4. The background to oral health education
The term Dental Health Education (DHE) has been gradually superseded
in recent years by Oral Health Education (OHE), reflecting a wider
concern than health only of the teeth.
Problems with oral health education
Previous inadequacies in OHE delivery have been attributed to two main
faults.
The message which has been contained within the dental health advice has
not always been correct and has at times been totally misleading.
PATIENT EDUCATION
4
5. Domains of learning
In education it is accepted that there are three domains of learning
1. Cognitive domain: this relates to the acquisition of knowledge.
2. Skills domain: this is the learning of practical skills.
3. Affective domain: this involves the creation of attitudes and
motivation.
THE LEARNING PROCESS
5
6. The prevention and control of the two major dental diseases
inflammatory periodontal disease and dental caries, depend to a large
extent on a change in the behavior of the patient.
Changing behavior
The following are the steps which must be followed to establish
behavioral changes
Factual education.
Practical demonstration.
Motivation.
Reinforcement.
BEHAVIORAL CHANGE
6
7. Information is a necessary but not on its own sufficient condition for
changing behavior.
The information supplied should be accurate and comprehensible to lay-
people.
Part of this information should include realistic goals that the patient can
achieve.
For example, with some patients it would be preferable to concentrate
solely on the improvements achievable by brushing before progressing to
interdental cleansing.
FACTUAL EDUCATION
7
8. The teaching of the physical skills involved in dental health includes
disclosing, brushing, interdental cleansing and the cleaning of dentures and
appliances.
Educator should use 'tell-show-do' approach.
The action should first be explained, then demonstrated to the patient,
possibly at first on models, then in the mouth.
Finally, the patient should carry out the procedure with the instructor
supervising, correcting and giving encouragement.
Do not overload the patient.
It is better to teach a little at a time.
PRACTICAL TRAINING
8
9. Refers to 'that which induces a person to act'.
In dentistry, the phrase 'patient motivation' is often misused, implying that
one can cause a third person to co-operate, comply or perform in some
desired manner.
This would be a very useful ability, but unfortunately not possible.
Motivation must come from within an individual.
MOTIVATION
9
10. In order to become motivated to alter a behavioral pattern an individual
must be able to identify the following:
1. A problem exists which affects the individual personally
for example the existence of periodontal disease in the mouth.
2. The problem will have an unwanted personal outcome
such as the premature loss of teeth.
3. There is a practical solution
such as adequate plaque control.
4. The problem is serious enough to justify the inconvenience of the
solution.
THE ESSENTIALS FOR
MOTIVATION
10
11. In relation to dental health education, people may be divided into three broad
groups:
- those who are already motivated,
- those with latent motivation,
- those lacking the necessary motivation to change their behavior
Motivated have their own drive and simply require guidance and reinforcement
from time to time.
Latent motivation is possessed by a majority of patients.
This is indicated by studies which show that approximately 60% of patients attend
a dentist at least every second year, usually for a preventive check-up.
This latent motivation requires a trigger to activate or release it.
THE ESSENTIALS FOR MOTIVATION
11
12. Patients without the desired motivation are intractable problem.
Various forms of threat or sanction may produce an improved short-term
behavioral change, but no long-term alteration.
However, even these patients may not be lost for ever, as research
suggests that the priority of motives may change with time and
circumstances, even in adults, and this will give rise to behavioral changes.
THE ESSENTIALS FOR MOTIVATION
12
13. The process of encouraging or establishing a belief or pattern of behavior.
Once the progression of the disease has been controlled, then most
patients require a regular (possibly 3 monthly) maintenance programme of
visits.
This can be coupled with reinforcement of the oral hygiene regimen.
The frequency of reinforcement will vary from person to person and will
depend to a large extent on their attitudes and the type of problem
present.
REINFORCEMENT
13
14. A. Learning is more effective when an individual is physiologically and
psychologically ready to learn.
B. Individual differences must be considered if effective learning is to take place.
C. Motivation is essential for learning.
D. What an individual learns in a given situation depends on what is recognized
and understood.
E. Transfer of learning is facilitated by recognition of similarities and
dissimilarities between past experiences and the present situation.
F An individual learns what is actually used.
G. Learning takes place more effectively in situations from which the individual
derives feelings of satisfaction.
H. Evaluation of the results of instruction is essential to determine whether
learning is taking place.
PRINCIPLES OF LEARNING
E M WILKINS 2005
14
15. The learning ladder illustrates the six steps from learner unawareness to
habit formation.
When beginning to help a patient learn about oral health and what the
individual's needs are, one must determine where the patient stands on the
ladder and start from there.
THE LEARNING LADDER
15
16. A. Unawareness
Many patients have little concept of the new information about dental and
periodontal infections and how they are prevented or controlled.
B. Awareness
Patients may have a good knowledge of the scientific facts, but they do not
apply the facts to personal action.
C. Self-interest
Realization of the application of facts/knowledge to the well-being of the
individual is an initial motivation.
THE LEARNING LADDER
16
17. D. Involvement
With awareness and application to self, the response to action is forthcoming
when attitude is influenced.
E. Action
Testing new knowledge and beginning of change in behavior may lead to an
increased awareness that a real health goal is possible to attain.
F. Habit
Self-satisfaction in the comfort and value of sound teeth and healthy
periodontal tissue helps to make certain practices become part of daily routine
Ultimate motivation is finally reached.
THE LEARNING LADDER
17
18. Periodontal health is important teeth are worth keeping for life.
The patients must believe this; otherwise any change in habit as an
immediate response will be short-lived.
Several arguments may be employed and the experienced practitioner can
tailor these to the patient's perceived needs.
Adolescents and adults may respond to different arguments
CHANGE IN ATTITUDE TO DENTAL HEALTH
DM ELEY, JD MANSON 2OO4
18
19. Impaired function
No appliance can function as efficiently as the natural and healthy
dentition
Full dentures may be an extremely poor substitute for the patient's own
teeth.
ATTITUDE TO DENTAL HEALTH
19
20. Personal hygiene.
These days most people are concerned about personal cleanliness and yet
there may be a marked contrast between the patient's general appearance
and the state of his mouth.
This usually represents a lack of awareness of oral hygiene and when the
true state of affairs is demonstrated the individual who is truly concerned
about personal hygiene will be ready to change his habits.
The patient is given a hand-mirror to witness the examination of the
mouth, and deposits of plaque and calculus can be pointed out.
The use of a disclosing agent is valuable.
ATTITUDE TO DENTAL HEALTH
20
21. Social handicap
Periodontal disease produces halitosis, inflamed gingiva and eventually
tooth loss due to mobility
The idea of possessing offensive breath or an ugly smile is often sufficient
incentive for patients to improve their home care.
General health
The fact that periodontal disease can have an adverse effect on general
health should be explained to the patient.
ATTITUDE TO DENTAL HEALTH
21
22. Based on the concept that one's beliefs direct behavior; model is used to
explain and predict health behaviors and acceptance of health
recommendations; emphasis is placed on perceived world of individual,
which may differ from objective reality
Components
1. Susceptibility-individuals must believe that they are susceptible to a
particular disease or condition
2. Severity-individuals must believe that if they get the particular disease or
condition, the consequences will be serious
3. Asymptomatic nature of disease-individuals must believe that the disease
may be present without their full awareness
4. Behavior change will be beneficial-individuals must believe that there are
effective means of preventing or controlling the potential or existing
problem and that action on their part will produce positive results
HEALTH BELIEF MODEL
M L DARBY 1998
22
23. Theory regarding human nature that is used to explain the motivational
process
Maslow suggested that inner forces, or needs, drive a person to action
He classified needs in a pyramid according to their importance to the
individual, his or her ability to motivate, and the importance placed on
their satisfaction
Only when an individual's lower needs are met, will the individual become
concerned about higher level needs
Once needs are met, they no longer function as motivators
"MASLOW'S HIERARCHY OF NEEDS
23
24. HIERARCHY OF NEEDS
24
self-realization needs that
drive the individual to reach the
very top of his or her field
components necessary for body
homeostasis, such as food, water,
oxygen, temperature regulation etc
Social needs
25. The first task of the practitioner is to establish rapport with the patient, which
then makes possible further development of communication, learning, and
motivation.
Despite their importance, history taking, clinical examination, and diagnosis must
all wait because, according to Meares 1957, while they may all occur concurrently
with rapport, rapport must come first.
ESTABLISHMENT OF COMMUNICATION : RAPPORT
H E GOLDMAN 1980
25
26. Rapport is an emotional state in which logical, intellectual, or verbal
factors may play only a small role.
Expressions, gestures, and other nonverbal communication, however small,
may assume symbolic value to the patient as the initial meeting with the
doctor takes place.
On the surface the patient may be reciting his symptoms and concerns, but
underneath this veneer he is assessing the competence and trustworthiness
of the doctor.
Meanwhile the doctor should be establishing the emotional relationship
with the patient that we know as rapport.
RAPPORT….
26
27. In considering obstacles to rapport the dentist should note the difference
between sympathy and empathy.
Empathy, a great gift for a professional to possess, means that although we
do not share the emotional feelings with the patients as in sympathy, we
do appreciate how he is feeling.
Empathy is a blend of interest and objectivity.
Many times the more sensitive the individual happens to be, the more apt
he is to possess a capacity for empathy.
Lack of this qualification by professional is an obstacle to formation of
rapport with his patients or clients.
SYMPATHY / EMPATHY
27
28. Cinotti and Grieder advocate methods that may prove to be effective and
more efficient.
These are conditioning and insight learning.
Conditioning
The dental patient is conditioned by past experiences to expect pain and
discomfort before he visits the dental office.
In our society, the dentist is often portrayed in cartoon and lay articles as a
threatening mutilator of the mouth who is to be feared.
It has been stated by many that the most feared figure in our society is the
psychiatrist and that the dentist is possibly a close second
Friedman
METHODS OF PATIENT
EDUCATION
28
29. In attempting to reeducate such patients many practitioners perform no
treatment per se on the first visit but use it to establish rapport and com-
munication and to commence the unlearning of old ideas and fears and the
learning of old ideas and fears and the learning of new values.
If several visits elapse without pain the former traumatic association is
weakened, and the patient is conditioned to become less fearful in the
dental situation.
The dentist may then proceed with the full treatment that is needed.
METHODS OF PATIENT EDUCATION
29
30. Insight learning.
If every patient came to the dentist with no previous dental experience
or knowledge, patient education would be not only easy but almost
effortless because no previous erroneous concepts would have to be
unlearned.
There would be no negative conditioning or avoidance reactions already
established.
Treatment could be started immediately, and insight learning could be
instituted as treatment proceeded.
Insight occurs when there is an instantaneous association between
formerly unknown or poorly understood events and present happenings.
In the process the individual avoids trial and error and the long-term
building up of associations required in conditioning.
METHODS OF PATIENT EDUCATION
30
31. Education of the patient continues throughout the examination.
A useful list of objectives to be accomplished by the dentist in
consultation would include the following:
1. Determine the patient's needs, motives, and desires.
2. Make the patient feel important and accepted .
3. Give the patient some recognition and attention as an active
partner in treatment plan.
4. Use visual aids (especially the patient’s own mouth).
5. Be a good listener, especially in the earlier stages of consultation.
METHODS OF PATIENT EDUCATION
31
32. The term "motivation" means conveying to the patient, through a series of
words, gestures, and examples, the importance that self-performed oral hygiene
has in the health of the oral cavity.
A T Botticelli 2002
In order to achieve this goal, dentists must possess:
- Technical skill
- Communication skill
- Psychologic insight
Dentist may have great technical skill, but will not succeed in their profession
if they are unable to communicate with their patients in order to motivate them
MOTIVATION
32
33. OUR YOUTH - ORIENTED SOCIETY
OUR DESIRE TO BE PHYSICALLY ATTRACTIVE
SUPERSTITIONS AND FOLKLORE
SELF-DISCIPLINE
FACTORS THAT INFLUENCE
PATIENT MOTIVATION
33
34. Our society is a youth oriented one and those things that enable us to prolong
our youth and retain our youthful appearance are much sought after and
valued.
Teeth are the most important physical facial feature that, if lost almost single
handedly give the impression of the onset of old age.
Old age has been portrayed for centuries as a period of toothlessness with a
collapse of vertical dimension in the face, subsequent characteristic changes
in speech and facial form, and an increase in wrinkling.
Therefore from the aesthetic standpoint teeth are important, not purely for a
superficial attractiveness, but also from more deep-seated fear of aging.
OUR YOUTH - ORIENTED
SOCIETY.
34
35. Teeth are a major factor in preserving a pleasant facial expression that
helps us retain our attractiveness to the opposite sex.
Attractiveness in men and women is aided immeasurably by the presence
of teeth —hopefully natural teeth.
OUR DESIRE TO BE
PHYSICALLY ATTRACTIVE
35
36. Many times facts regarding teeth and the pathology associated with them are
warped slightly incorrect to the extent of preventing patients from receiving
proper advice on retaining their teeth and preventing dental disease.
Practitioners have repeatedly heard about the "soft" teeth or the familial
susceptibility to decay or pyorrhea.
Folklore also contributes its share of distortion to the truth.
H E Goldman 1980
SUPERSTITIONS AND
FOLKLORE
36
37. Tonge (1965) indicates that this reputation is no doubt due to the fact that
teeth are the most lasting parts of our bodies, as demonstrated by skeletal
remains from all parts of the world.
In present-day life some evidence of' our respect for teeth still remains.
We still use eruption of teeth as a measure of maturity in the child.
SUPERSTITIONS AND
FOLKLORE….
37
38. Both caries and periodontal disease are by nature chronic and thereby
slowly progressive.
The practice of preventive measures to prevent future disease and
discomfort requires considerable self-discipline by the patient.
Age. Another factor that may be a barrier to successful motivation is the
fact that most periodontal patients are adults.
Adults are more difficult to change from their habits of neglect because
their previously held concepts must be overcome before learning can take
place.
On the other hand an adult can learn from another's experience and can
accept long-range goals better than a younger patient can.
SELF-DISCIPLINE
38
39. DARBY , WALSH 1995
1.Self-efficacy Theory
Self-efficacy, also known as self-confidence, is the belief in one's ability to
perform specific behaviors.
Self-efficacy theory maintains that self-confidence about being able to perform
a behavior has a strong influence on the ability to perform that behavior.
Based on self-efficacy theory, motivation to brush and floss should be stronger
when clients feel confident that they know how to floss and have the skill to do
so.
An important role of the dental hygienist is to help clients acquire this
confidence by training them to perform personal oral hygiene skills and by
providing them with ongoing support and encouragement.
THEORIES OF MOTIVATION
39
40. 2.Attribution Theory
Attributions are the explanations individuals give for their performance.
Attribution theory is a cognitive theory that emphasizes the importance of
content of thoughts.
What people attribute to their success or failure determines their feelings about
themselves, their predictions of success at accomplishing the task, and the
probability that they will try harder or not as hard at a task in the future.
For example, when people attribute their failure to low ability, they feel
depressed, predict that they will fail again, and use less effort in the future.
therefore attributions affect expectations of success, emotional (affective)
reactions, and persistence at future tasks.
THEORIES OF MOTIVATION
40
41. Some clients may blame someone or something else for their poor
performance in maintaining oral health.
Those people believe that external aspects or their environment have
control over their failure (or their successes)
The counterpart to these individuals is those who believe they hold their
fates in their own hands and are responsible for their own actions.
They are focused on the internal aspects of themselves and how they can
influence their environment.
Psychologists categorize such internal and external personality
dispositions under the construct locus of control.
LOCUS OF CONTROL
41
42. He developed a 23-item internal-external locus of control scale for
classification of individuals.
Three examples of items on Rotter's scale allow the respondent to read each
statement and select the statement he or she most agrees with.
1a. Many times I feel that I have little influence over things that happen to me.
(external)
1b. It is impossible for me to believe that chance or luck plays an important
role in my life (internal)
2a. Getting a good job depends mainly on being in the right place at the right
time (external)
2b. Becoming a success is a matter of hard work; luck has little or nothing to do
with it. (internal)
3a. Without the right breaks one cannot be an effective leader (external)
3b. Capable people who fail to become leaders have not taken advantage of their
opportunities (internal)
SOCIAL LEARNING THEORY
OF ROTTER
42
44. SOURCES OF INFORMATION ON PERIODONTAL THERAPY.
(H E GOLDMAN 1980)
Dentist is not the sole source of information about dental disease and its
treatment.
Before a Patient makes a dental visit oriented toward prevention, he must have
already been informed to some degree about the dangers of neglecting his
dental health.
He might have been informed by any one of great number of sources , some of
which are listed as follows:
1. Family or friends
2. Mass media-television, radio, magazines
3. Past experiences —personal and family
4. Fear of future pain and discomfort
5. Other authorities —physicians, school teachers, nurses
6. Social and cultural background44
45. At this point he may not be aware of the status of his periodontal health
but be concerned only about the problems associated with dental caries.
The major source of information about periodontal disease should be the
private practitioner of dentistry.
We must assume that the patient has come to a dental office for some
definite reason.
The dental practitioner may then take steps to inform him through a
suitable means of communication to arouse in him a need for the required
periodontal therapy.
SOURCES OF INFORMATION ON
PERIODONTAL THERAPY.
45
46. Actions that dentists and the dental profession may take to improve the
milieu in which the patient will motivate himself can be considered as either
extramural or intramural procedures (Katz et al 1972)
Extramural procedures
Because most periodontal patients are adults, and adults have beliefs that are
often difficult to change, the profession should concentrate on informing
patients when they are children.
Extramurally this could be done by the dental profession through a more
active participation in the health program at the elementary school level.
It could be accomplished by supplying attractive audiovisual materials to the
school, by participating in school functions, and by cultivating and educating
the teachers, who are very powerful opinion makers in the child's life.
Parents may be approached by other dentally educated opinion makers
such as physicians and nurses.
SUGGESTIONS FOR MOTIVATING
PATIENTS
46
47. Intramural procedures
Once the patient makes an appointment with the dentist, he has evidenced
a certain amount of need, or the appointment would never have been
made.
After he arrives, stronger motivation is evidenced.
Even though the patient has not come to the office for relief of pain, you
may assume that he has come for the relief of some other anxiety (disquiet
of mind).
SUGGESTIONS FOR MOTIVATING
PATIENTS
47
48. Kegeles (1963) has suggested a procedure for dealing with such a patient.
He indicates that the following format is a useful framework in which to
educate the patient relative to dental disease.
For a patient to make a dental visit and to undergo treatment that is
oriented toward prevention he must believe the following:
1. That he is susceptible to periodontal disease
2. That periodontal disease is personally serious
3. That there is something he can do to treat or correct the condition
4. To a lesser degree that the condition occurred due to natural causes
SUGGESTIONS FOR MOTIVATING
PATIENTS
48
49. A patient must first believe that he is susceptible to periodontal disease
before he can possibly consider the personal seriousness of it.
Likewise he must accept his susceptibility and its seriousness before he
can be required to consider whether any action that he may take will be
beneficial in treating the problem.
If the patient accepts the fact that periodontal disease is serious for him,
but does not accept the fact that he is susceptible to it., he will never take
any beneficial action.
Similarly, if he believes that he is susceptible, but that it is of no
consequence, he will never agree to treatment.
In like manner he may accept his susceptibility and its seriousness for him
and yet not believe that periodontal therapy and oral hygiene will help him.
He still will not take beneficial action.
SUGGESTIONS FOR MOTIVATING
PATIENTS
49
50. Therefore Kegeles outlines must be followed.
The dentist must develop a suitable presentation that will convince the
patient that he has every right to expect that, as a member of the human
race, he is susceptible to periodontal disease
If the dentist is aware of some of the motives that compel men to action,
he may similarly present the patient with factual information on the
seriousness of tooth loss from the financial, hygienic, functional, esthetic,
or psychological aspects.
The choice of approach depends on the patient's values in relation to his
teeth.
SUGGESTIONS FOR MOTIVATING
PATIENTS
50
51. Once the patient has truly accepted both his susceptibility and the serious
nature of periodontal disease he will probably ask the dentist what he can
do about treating the condition.
At this point a personal disease control program is outlined.
The individual dentist and his complete office staff should have their dental
disease under control and should enthusiastically teach such a program to all
patients (Kutz et al 1972).
Kegeles' last point states that the patient must believe that periodontal disease
has occurred in his mouth due to natural causes.
This means that the patient should accept his condition as a natural biologic
sequence of events and not as a punishment evoked by God for some past
sins.
Occasionally, successful patient motivation is blocked by such a belief.
SUGGESTIONS FOR MOTIVATING
PATIENTS
51
53. Patients can reduce the incidence of plaque and gingivitis with repeated
instruction and encouragement much more effectively than with self-
acquired oral hygiene habits
Gravelle et al 1967, Suomi et al 1969
However, instruction in how to clean teeth must be more than a cursory
chair side demonstration on the use of a tooth brush.
It is a painstaking procedure that requires patient participation, careful
supervision with correction of mistakes, and reinforcement during return
visits, until the patient demonstrates that he or she has developed the
necessary proficiency
Anderson JC 1972, Less W 1972
ORAL HYGIENE INSTRUCTIONS
53
54. Any strategy for introducing plaque control to the periodontal patient
includes several elements.
At the first instruction visit, the patient should be given a new toothbrush,
an interdental cleaner, and a disclosing agent.
The patient’s plaque should be disclosed because dental plaque otherwise is
difficult for the patient to see
Newman et al 2006
ORAL HYGIENE INSTRUCTIONS
54
55. A - Because bacterial plaque is relatively invisible and many tooth surfaces are
not easily accessed, teaching patients the skills necessary for disease control
can be difficult.
B -Agents that make supragingival plaque visible can enhance the teaching-
learning process by
i) Demonstrating a relationship between the presence of supragingival
plaque and the clinical signs of disease.
ii) Guiding skill development when applied before plaque removal.
iii) Allowing evaluation of skill effectiveness when applied after plaque
removal.
BACTERIAL PLAQUE DETECTION
M L DARBY 1998
55
56. C - Presence of subgingival plaque cannot be demonstrated by the use of
disclosing agents.
D - Plan for disease control education should include establishing the
association between the presence of plaque and clinical signs of
disease, such as bleeding.
E - Subgingival plaque detection by the client is best managed when there is
an understanding of the gingival sulcus and/or pocket and the
clinical changes that will occur when bacterial plaque removal is not
effective
BACTERIAL PLAQUE DETECTION
56
57. I. Purposes
A disclosing agent clearly demarcates soft deposits that might otherwise
be invisible and therefore facilitates the following:
a. Personalized patient instruction in the location of soft deposits
and the techniques for removal.
b. Self assessment by the patient on a daily basis during initial
instruction and periodic checks thereafter.
c. Continuing evaluation of the effectiveness of the instruction for
the patient.
i) Determining the need for revision of the biofilm control procedures.
ii) Studying the long term effects over successive maintenance
appointments.
DISCLOSING AGENTS
E M WILKINS 2005
57
58. d. Preparation of biofilm indices.
e. Conducting research studies to gain new information about the
incidence and formation of deposits on the teeth, the effectiveness
of the specific diseases for dental biofilm control, and anti biofilm
agents and to evaluate clinical and instructional group health
programs.
DISCLOSING AGENTS
58
59. II. Properties of an acceptable disclosing agent
A. Intensity of Color : A distinct staining should be evident, color should
contrast with normal colors of oral cavity.
B. Duration of Intensity: should not rinse off immediately with ordinary
rinsing methods, neither should it be removable by the saliva for the
period of time required to complete the instruction or clinical service.
C. Taste: The patient should not be made uncomfortable by an unpleasant or
highly flavored substance
D. Irritation to the mucous membrane: The patient should be questioned
concerning the possibility of an idiosyncrasy to an ingredient.
DISCLOSING AGENTS
59
60. E. Diffusibility: A solution should be thin enough so it can be applied readily
to the exposed surfaces of the teeth, yet thick enough to impart an
intense color to dental biofilm.
F. Astringent and Antiseptic Properties : These properties may be highly
desirable in that the disclosing agent may contribute other factors to
the treatment procedures
DISCLOSING AGENTS
60
61. III. Formulae
A variety of disclosing agents has been used.
Skinner’s iodine solution was formerly the most classic and widely used.
In general, iodine solutions are less desirable because of their unpleasant
flavor.
Aniline dyes have been shown to have carcinogenic potential.
Therefore, the use of basic fuchsine and beta rose (flavored basic
fuchsine) has been discouraged.
Other well-known agents are Buckley’s Berwic’s, Talbot’s iodo-glycerol, and
Metaphen solutions.
DISCLOSING AGENTS
61
63. 1V Methods for application
A. Solution for Direct Application
(Painting)
1. Have patient rinse to remove food particles and heavy saliva.
2. Apply water-based lubricant generously to prevent staining of the lips.
3. Dry the teeth with compressed air, retracting cheek or tongue
4. Use swab or small cotton pellet to carry the solution to the teeth
5. Apply solution generously to the crowns of the teeth only.
6. Direct the patient to spread the agent over all surfaces of the teeth with the
tongue
7. Examine the distribution of the agent and request the patient to rinse if
indicated.
DISCLOSING AGENTS
63
64. B. Rinsing
A few drops of a concentrated preparation are placed in a paper cup and
water is added for the appropriate dilution.
Instruct the patient to rinse and swish the solution over all tooth surfaces.
C. Tablet or Wafer
The patient chews the wafer (one half may be sufficient for some patients),
swishes it around for 30 to 60 seconds, and rinses.
DISCLOSING AGENTS
64
65. V. Interpretation
A. Clean tooth surfaces do not absorb the coloring agent; when pellicle and
dental biofilm are present, they absorb the agent and are disclosed
B. Pellicle stains as a thin, relatively clear covering whereas dental biofilm
appears darker, thicker, ' and more opaque.
C. Two-Tone
1. Red Biofilm. Newly formed, thin, usually supragingival.
2. Blue Biofilm. Thicker, older, more tenacious; usually it is seen at
and just below gingival margin, especially on proximal surfaces and
where brush or floss is not easily applied; may be associated with
calculus deposits.
DISCLOSING AGENTS
65
68. VI. Patient instruction

70. The bristle toothbrush appeared about the year 1600 in China, was first
patented in America in 1857.
Generally tooth brushes vary in size and design, as well as length,
hardness, and arrangement of the bristles. Silverstone LM , Featherstone MJ
1988
The American Dental Association has described the range of dimensions
of acceptable brushes:
- Length : 1 to 1.25 inches
- Width : 5/16 to 3/8 inches
- Surface area : 2.54 to 3.2 cm
- No. of rows : 2 to 4 rows of brushes
- No. of tufts : 5 to 12 per row
- No. of bristles : 80 to 85 per tuft
TOOTH BRUSHES

72. A. Sequence
1. A methodical, systematic approach will enhance effectiveness
2. Suggested sequence: begin systematic overlapping strokes at the facial
aspect of the maxillary right or left terminal tooth and continue around the
arch to the terminal tooth on the opposite side; switch to the lingual aspect
and begin working back toward the starting side; use the same pattern for the
mandible, then brush the occlusal surfaces.

73. B. Duration
1. Each time the brush is moved, the time spent in an area should be
monitored by counting strokes or seconds
2. Total manual brushing time of 3 to 5 minutes has been suggested; powered

74. C. Frequency
1. Thorough bacterial plaque removal once a day is the minimum requirement
for maintaining periodontal health; it may not, however, be the
optimum regimen for some individuals
2. Frequency should be increased when gingival or periodontal conditions
warrant it or when caries risk or activity is high
3. Brushing removes residual food debris as well as bacterial plaque and is one
method for self application of topical fluoride

75. D. Skill level
1. Careful attention should be given to evaluating skill development in all
components of brush manipulation, including grasp, placement,
activation, wrist movement, and amount of pressure applied
2. Control of brush placement and motion is essential for effectiveness

75
76. Roll: Roll method or modified Stillman technique
Vibratory: Stillman, Charters, and Bass techniques
Circular: Fones technique
Vertical: Leonard technique
Horizontal: Scrub technique
Scrub technique: probably the simplest and most common method of
brushing.
Patients with periodontal disease are most frequently taught a sulcular
brushing technique using a vibratory motion to improve access in the
gingival areas.
The method most often recommended is the Bass technique because it
emphasizes sulcular placement of bristles.
TOOTHBRUSHING METHODS
76
77. Place the head of a soft brush parallel with the occlusal plane, with the
brush head covering three to four teeth, beginning at the most distal tooth
in the arch.
Place the bristles at the gingival margin, pointing at a 45-degree angle to the
long axis of the teeth.
Exert gentle vibratory pressure, using short, back and forth motions
without dislodging the tips of the bristles.
This motion forces the bristle ends into the gingival sulcus area as well as
partly into the interproximal embrasures.
The pressure should be firm enough to blanch the gingiva
Complete several strokes in the same position.
Lift the brush, move it to the adjacent teeth, and repeat the process for the
next three or four teeth.
BASS TECHNIQUE
BASS CC 1954
77
78. BASS TECHNIQUE
• Place the toothbrush so
that the bristles are
angled approximately 45
degrees from the tooth
surfaces.
• Start at the most distal
tooth in the arch, and use
a vibrating, back-and
forth motion to brush.
78
79. A. Proper position of the brush in the mouth aims the bristle tips toward the
gingival margin.
B. Diagram shows the ideal placement, which permits slight subgingival
penetration of the bristle tips.
BASS TECHNIQUE
79
81. Brush is placed with bristles resting partly on cervical portion of tooth and
partly on adjacent gingiva, pointing in an apical direction at an oblique
angle to long axis of tooth
Pressure is applied laterally towards gingival margin to produce blanching
Brush is activated with 20 short back and froth strokes and is
simultaneously moved in coronal direction along attached gingiva, gingival
margin and tooth surface.
Recommended in patients with progressing gingival recession and root
exposure to prevent abrasive tissue destruction
STILLMAN METHOD
STILLMAN PR 1932
81
82. Brush is placed with bristles pointed towards the crown at 45 degree angle
to long axis of the teeth
Sides of the bristles are flexed against the gingiva, and the back and froth
vibratory motion is used to massage the gingiva
Bristle tips should not move across the gingiva
Suitable for gentle plaque removal and gingival massage
Indicated in healing wounds after periodontal surgery

84. Each of these methods can be modified to add a roll stroke.
The brush is positioned similarly to the Bass/Stillman technique.
After activation of the brush head in a back-and-forth direction, the head
of the brush is rolled over the gingiva and tooth in the occlusal direction,
making it possible for some of the filaments to reach interdentally.
MODIFIED BASS/STILLMAN
TECHNIQUE
84
85. A. Brushes should be rinsed clean after each use, allowed to air-dry in an
upright position
B. Rotating use of more than one brush during 24 prolongs brush life
C. Brushes should be replaced when bristles splay resiliency, generally no
longer than 3 to 4 months.
D. Some brushes have color indicator bristles to monitor replacement time
E. Brushes should be replaced after an illness such or flu or disinfected with a
household bleaches

87. Powered toothbrushes rely primarily on mechanical contact between the
bristles and the tooth to remove plaque.
The addition of low-frequency acoustic energy generates
dynamic fluid movement and provides cleaning slightly
away from the bristle tips.

89. Definition
Substance used with a tooth brushes are accessible tooth surfaces; available in
gel, paste or powder form.
Purposes
1. Cosmetic – Tooth surfaces are cleaned and polished, breath is freshened.
2. Therapeutic – Certain non drug substances augment the efficiency of the
brush in removal of plaque debris and stain; Vehicle for transporting
biologically active ingredients to the tooth and its environment;
fluoride dentifrices inhibit tooth demineralization
DENTIFRICES

seal
B. All ADA accepted dentifrices have safe levels of abrasiveness
C. Dentifrices containing fluoride are granted acceptance based on their
caries-reduction properties
GUIDELINES FOR

90
91. D. Dentifrices that carry the ADA seal have gained acceptance for the
proven efficacy of the fluoride mechanism
E. Desensitizing dentifrices that carry the ADA seal have gained acceptance
for proven efficacy in the control of dentinal hypersensitivity
F. Dentifrices that claim therapeutic benefits other than dental caries
reduction (from fluoride) or control of hypersensitivity have not been
awarded the ADA seal for such claimed benefit
GUIDELINES FOR
DENTIFRICE SELECTION
91
92. A. Daily use of fluoride dentifrice should be recommended for all individuals,
regardless of caries risk, because these products promote tooth
remineralization
B. Young children (under age 6) should be supervised when using fluoride
dentifrice
C. Use of a small pea-sized amount of toothpaste gel containing no more
than 1100 ppm fluoride is recommended swallowing should be avoided
dental fluorosis has been associated with use of more than a pea sized
amount of toothpaste by young children living in fluoridated
communities

93. Any toothbrush, regardless of the brushing method used does not
completely remove interdental plaque
This is true for all brushers even periodontal patients with wide open ,
embrasures. Gejermo et al1970, Schmidet al 1976
Daily interdental plaque removal is crucial to augment the effects of tooth
brushing because most dental and periodontal diseases originate in
interproximal areas Addy et al 1998
Tissue destruction associated with periodontal disease often leaves large,
open spaces between teeth and long, exposed root surfaces with anatomic
concavities and furcation's.
These areas are both difficult for patients to clean and poorly accessible to
the toothbrush Kinane 1998
INTERDENTAL CLEANING AIDS
93
94. Many tools are available for interproximal cleaning.
They should be recommended based on the patient's interdental
architecture (e.g., size of interdental spaces), Presence of furcation's, tooth
alignment, and presence, of orthodontic appliances or fixed prostheses.
Also, ease of use and patient cooperation are important considerations.
Common aids are dental floss and interdental cleaners such as wooden or
plastic tips and interdental brushes.

96. Dental floss is the most widely recommended tool for removing plaque
from proximal tooth surfaces.
Floss is available as a multifilament nylon yarn that is twisted or
nontwisted, bonded or nonbonded, waxed or unwaxed, and thick or thin.
Some prefer monofilament flosses made of a nonstick material because
they do not fray.
Clinical research has demonstrated no significant differences in the ability
of the various types of floss to remove dental plaque
they all work equally well. Grossman 1979, Keller 1969
Waxed dental floss was thought to leave a waxy film on proximal surfaces,
thus contributing to plaque accumulation and gingivitis.
Robert H. Beaumont 1990
DENTAL FLOSS
96
97. Dental floss should be held
securely in the fingers or tied
in a loop. (12-18 “)
Dental floss technique.
The floss is slipped between the
contact area of the teeth, is
wrapped around the proximal
surface, and removes plaque by
using several up-and-down
strokes. 97
99. INTERDENTAL BRUSH
(PROXY BRUSH)
Interdental brush are conical shape brushes made of bristles mounted on
a handle / single tufted brushes.
Suitable for cleaning large, irregular, or concave tooth surfaces adjacent to
wide interdental spaces.
Inserted inter-proximally and are activated with short back and forth
strokes in between the teeth.
99
101. The dorsum of the tongue harbors a great number of microorganisms.
These bacteria may serve as a source of bacterial dissemination to other
parts of the oral cavity.
Therefore, tongue brushing has been advocated as part of daily home oral
hygiene together with tooth brushing and flossing, since this might reduce
a potential reservoir of microorganisms contributing to plaque formation
Christen & Swanson 1978
The bacterial accumulations on the dorsum of the tongue may also be the
source of bad breath.
TONGUE CLEANER

102. Massaging the gingiva with a toothbrush or an interdental cleaning devices
produces epithelial thickening. increased keratinization, and increased
mitotic activity .
Canter et al1965, Castenfelt 1952, Glickman et al 1965
The increased keratinization occurs only on the oral gingiva and not the
areas more vulnerable to microbial attack the sulcular epithelium and
the interdental areas where the gingival col is present.
Improved gingival health associated with interdental stimulation is much
more likely the result of plaque removal than gingival massage.
GINGIVAL MASSAGE

103. Chemical plaque control can augment mechanical plaque control
procedures.
Fluoride preparations are essential for caries control in periodontal
patients.
Antimicrobial oral rinses will reduce gingivitis in periodontal patients.

pressure, steady or pulsating stream of water through a nozzle to the tooth
surfaces.
Most often, a device with a built-in pump generates the pressure
Oral irrigators clean non-adherent bacteria and debris from the oral cavity
more effectively than toothbrushes and mouth rinses.
Irrigators are particularly helpful for removing debris from inaccessible
areas around orthodontic appliances and fixed prostheses.
When used as adjuncts to tooth brushing, these devices can have a
beneficial effect on periodontal health
Both supra and sub-gingival irrigators are available

118. Coarse fibrous foods
As part of the plaque control program patients should be advised to include
hard fibrous foods in their diet, particularly at the end of meals.
Although some investigators disagree (Lindhe et al 1969) it is the consensus that
hard fibrous foods reduce plaque accumulation and gingivitis on tooth surfaces
exposed to their mechanical cleansing action during mastication
Bear et al 1961, Stewart et al 1960
Coarse fibrous foods functional stimulation to the periodontal ligament and
alveolar bone.
Soft diets increased plaque accumulation and calculus formation, gingivitis
and periodontal disease Plezer et al 1940
Animals fed soft diets enriched with vitamins and minerals develop severe
periodontal disease with loosening of the teeth, which does not occur when
the diet includes lengths of bone and adherent meat which require
vigorous chewing King et al 1945
DIET
GLICKMAN 1972
121
119. Limiting sucrose-containing foods
The fact that the ingestion of sucrose increases plaque formation is of
great clinical importance.
The polysaccharide dextran is a major component of the plaque matrix.
It is a sticky substance which envelops the plaque bacteria and attaches the
plaque to the tooth surface.
The bacteria form the dextran from carbohydrates, particularly sucrose.
Limiting the intake of sugar and sugar-sweetened foods assists in reducing
plaque formation (Carlson et al 1965) and patients should be instructed
accordingly.

122
120. No therapeutic intervention is without adverse effects, including oral
hygiene practices.
Tooth abrasion and gingival recession are both alleged to be caused by
traumatic brushing.
Tooth Abrasion
Evidence implicating the toothbrush in cases of abrasion comes primarily
from in vitro studies, case reports, and cross-sectional studies.
Some studies have implicated a horizontal scrubbing stroke as a more
important risk factor for tooth abrasion than bristle stiffness.
Other studies have indicated that abrasive toothpastes are the primary
cause of tooth abrasion.

ADVERSE EFFECTS OF ORAL

123
121. Gingival Recession
Gingival recession is the result of an interaction between precipitating
factors, such as trauma to the gingival tissues, and predisposing factors,,
such as a thin tissue complex.
Gingival recession, particularly that occurring on the buccal surface, is
often presumed to be the result of toothbrush trauma.
It seems logical to assume that the thin gingival biotype might be more
easily traumatized.
There is evidence suggesting that thin tissue is more prone to recession

122. Possible Adverse Effects of Home Irrigation
A number of investigators have examined the effect of pulsating water jet
devices on gingiva and mucosa and most have concluded there is little risk
for tissue damage when such devices are used according to manufacturer's
instructions Rethman et al 1994
In one investigation, the use of an irrigator at 60 psi in untreated
periodontal pockets created no more tissue damage than was found in the
"no irrigation" control group Cobb et al 1988
Some investigators have reported no bacteremia after irrigation, whereas
others have reported that this does occur. Because this could have
implications for individuals at risk for endocarditis, some authorities have
recommended that the devices not be used by individuals at risk.

123. Thorough plaque removal may enhance the results of regenerative surgical
therapy and may help provide stability to the gains in clinical attachment
achieved Tonetti et al 1996
In the immediate postoperative period plaque control is accomplished by
means of chemotherapeutic agents such as chlorhexidine gluconate rinses,
and mechanical plaque removal is generally avoided.
Some tissue maturation should occur before resumption of normal oral
hygiene
Critical to the regenerative outcome is wound stability and the preservation
of the delicate fibrin forms on the root surface.
The presence of this fibrin clot may prevent the down growth of the
epithelium, there by permitting regeneration of the attachment apparatus
ORAL HYGIENE AFTER
REGENERATIVE PROCEDURES
126
124. It is often recommended that professional subgingival debridement and
probing be avoided for 6 months after regenerative surgery, but little is said
about the resumption of oral hygiene measures

125. The foundation of a preventive health-oriented dental practice is an
effective hygiene department.
We are responsible for delivering not only quality restorations with which
patients can prevent dental disease, but also a structured program to aid
them in taking care of their health and investment.
It is the quality of the dentist's restorations and the effectiveness of his or
her hygiene program that determine whether he or she is practicing true
preventive dentistry or simply functioning in a reparative manner-always
"putting out fires."

Dental plaque is defined as a specific but highly variable sturctural entity, resulting from colonisation and multiplication of microorganisms on tooth surface, restorations and other parts of the oral cavity which consists of salivary components like mucin, desquamated epithelial cells, debris and microorganisms all embedded in a gelatinous extracellular matrix. (WHO 1978)
Biofilms: defined as matrix embedded microbial populations, adhering to each other and/or to surfaces or interfaces. (Costerton 1995)
1. Early colonizers: are either independent or defined complexes. Member of Yellow (Streptococcus spp.) or Purple complexes (Actinomyces odontolyticus).
2. Secondary colonizers:Members of Green complexes (Eikenella corrodens, Actinobacillus actinomycetemcomitans serotype a, and Capnocytophaga species), Orange (Fusobacterium, Provotella and Camphylobacter) and Red complexes
However results of studies on tongue brushing as an adjunct to tooth brushing in order to reduce plaque formation are inconclusive Badersten et al 1975
Epithelial thickening, increased keratinization, and increased blood circulation have not been shown to be beneficial for restoring gingival health Glickman et al 1964
The bacterial cell is characteristically negatively charged. The cationic chlorhexidine molecule is rapidly attracted to the negatively charged bacterial cell surface, with specific and strong adsorption to phosphate-containing compounds. This alters the integrity of the bacterial cell membrane and chlorhexidine is attracted towards the inner cell membrane. Chlorhexidine binds to phospholipids in the inner membrane, leading to increased permeability of the inner membrane and leakage of low-molecular-weight components, such as potassium ions.
At this bacteriostatic (sublethal) stage, the effects of chlorhexidine are reversible; removal of excess chlorhexidine by neutralizers allows the bacterial cell to recover (22). This implies that the structural changes to the cytoplasmic membrane caused by low levels of chlorhexidine are minor compared with the gross damage caused by higher concentrations
(bactericidal) levels of the agent
Increasing the concentration of chlorhexidine causes progressively greater damage to the membrane, reflected in the size of the permeable species lost from the cell (36, 46). As the concentration of chlorhexidine increases, leakage of low-molecularweight cytoplasmic components falls, reflecting the coagulation and precipitation of the cytoplasm by The formation of phosphated complexes such as adenosine triphosphate and nucleic acids (22). Electron micrographs show the cytoplasm of such cells to be chemically precipitated; this bactericidal stage is irreversible (22
great affinity for the cell wall of microorganisms and changes the surface structures. Osmotic equilibrium is lost, and as a consequence,cytoplasmic membrane is extruded, vesicles are formed, and the cytoplasm precipitates (Davies 1973, Brecx & Theilade
