2. Periodontal disease is a result of complex interaction
between subgingival microflora and non bacterial factors
(host and environmental factors)
Bacteria alone in a compromised host or combined with
environmental factors increase the host susceptibility to
infection hence an increased risk of progressive periodontal
disease.

3. Periodontitis is a chronic multifactorial inflammatory
disease caused by microorganisms and characterized by
progressive destruction of the tooth supporting apparatus
leading to tooth loss.

9. Moreover, low education level is likely to lead to low
prestige and low pay occupations, and residing in deprived
area.
The impact of environmental conditions on periodontal
health is such that individuals living in a neighborhood in
the most socially marginalized areas experience twice the
risk of periodontitis relative to those in the most affluent.

12. Periodontitis is a major oral disease that is strongly
influenced by obesity, over weight and level of exercise.
Physical activity has shown to have a protective relationship
with several chronic diseases.*
12
*Mohammad S et al. Increased physical activity reduces prevalence of
periodontitis. Journal of Dentistry. 2005;33,(9): 703-710
13. The adverse effect of obesity on the periodontium may be
mediated through pro-inflammatory cytokines like
interleukins (IL-1, IL-6 and TNF-α), adipokines (leptin,
adiponectin, resistin and plasminogen activator inhibitors-1)
and several other bioactive substances like reactive oxygen
species (ROS), which may affect the periodontal tissues
directly.
13
14. Reactive oxygen species are products of normal cellular
metabolism but over-production of reactive oxygen species
induces damage by oxidizing DNA, lipids and proteins.
Obesity increases the circulation of reactive oxygen species
which in turn causes gingival oxidative damage and
progression of periodontitis

general health: Relationship and management.
15. A systematic review (2010) reported a positive association
for obesity in the development of periodontal disease.
There was a greater mean clinical attachment loss among
obese individuals, a higher mean body mass index (BMI)
among periodontal patients, and a trend of increasing odds
of prevalent periodontal disease with increasing BMI.*

Korean workers. Scientific Reports 2017;7: 7967
18. Nutritional intake has impact upon the levels of
inflammation seen in a number of diseases, and this is no
less the case in periodontitis.
Studies using an experimental gingivitis model have shown
increased levels of bleeding on probing when participants
were fed with a diet high in carbohydrates when compared
to those on a low sugar diet.
18
Sidi A, Ashley F. Influence of frequent sugar intakes on experimental gingivitis. J
Periodontol 1984; 55: 419-423.
19. Oxidative stress is a key driver of chronic inflammation and
as a result has a central role in the pathogenesis of a wide
range of chronic inflammatory diseases.
In health a fine balance exists between, oxidants and on the
other antioxidants which are found in all tissues of the body
19
20. A study (2013) reported the importance of total amounts of
simple sugars, carbohydrates and fat intake entering the
blood stream.
Also frequency of intake is a key factor in generating
oxidative stress, the more frequent the intake the greater the
inflammation recorded in blood vessels
20

21. A study (2011) reported that overweight students, the
frequent consumption of fatty foods and infrequent
consumption of vegetables were associated with an
increased risk of periodontitis.
In underweight and normal-weight students, eating habits
had little effect on the periodontal condition.

22. Periodontal disease progresses more rapidly in
undernourished population, the role of nutrition in
maintaining an adequate immune response explains this.
Periodontitis is associated with an increased production of
reactive oxygen species which, if not buffered cause damage
to host cells and tisssue.
22
23. Currently there is no strong evidence that supports the claim
of diet and nutrition as a causal factor for periodontitis.
However studies are investigating the protective role of
antioxidants nutrients in periodontitis.

vitamin B complex, vitamin C, vitamin D, calcium and
magnesium deficiencies with periodontal disease in elderly
people is not evident.

25. A Systematic review (2014) reported that Vitamin E, zinc,
lycopene and vitamin B complex may have useful adjunct
benefits.
However, there was inadequate evidence to link the
nutritional status of the host to periodontal inflammation.

26. Vitamins are essential for general heath and normal
functioning. Similarly, they are required for maintaining
health oral and periodontal tissues. Nutritional deficiency of
vitamins results in oral manifestations such as scurvy and
rickets.

27. Since epithelial tissues provide a primary barrier function to
protect against invading microorganisms, vitamin A plays an
important role in maintaining the epithelium.
Periodontal changes have been reported in vitamin A-
deficient rats:
27
28. 1. Hyperplasia and hyperkeratinisation of the gingival
epithelium with proliferation of the junctional epithelium.
2. Retardation of gingival wound healing

29. Vitamin C (ascorbic acid) is primarily required for the
synthesis of collagen and it also prevents oxidative damage
by acting as a Reactive Oxidative Species (ROS) scavenger.
Scurvy, first identified by Sir Thomas Barlow in 1883.
In addition to malaise, lethargy, and spots on the skin,
periodontal hallmarks of scurvy are bleeding, inflamed, and
painful gums.
29

2016, 8, 530
30. Ascorbic acid deficiency interferes with bone formation,
leading to loss of periodontal bone.
Depletion of vitamin C may interfere with the ecologic
equilibrium of bacteria in plaque and thus increase its
pathogenicity.
How ever there is no evidence to support the above
statement.

31. In humans, there are two important groups of vitamin D,
vitamins D2 (cholecalciferol) and D3 (ergocalciferol).
Clinical studies have suggested that a deficiency of dietary
vitamin D leads to periodontal inflammation and a delay in
post-surgical periodontal healing
31
32. However, clinical trials have found no significant link
between serum vitamin D levels and periodontal health.
Nevertheless, when the correlation between serum vitamin
D levels and disease progression was studied in individuals
over 60 years of age, an inverse relationship was observed.
32
Shariq Najeeb et al. The Role of Nutrition in Periodontal Health: An Update. Nutrients
2016, 8, 530
33. A longitudinal study (2011) reported that calcium and
vitamin D supplementation has a modest positive effect on
periodontal health, and consistent dental care improves
clinical parameters of periodontal disease regardless of such
supplements.

34. Vitamin E serves as an antioxidant to limit free-radical
reactions and to protect cells from lipid peroxidation.
Cell membranes, which are high in polyunsaturated lipids,
are the major site of damage in vitamin E deficiency.
Deficiency results in increased tendency for haemolysis
which affects cross linking of collagen

35. A study (2014) investigated the levels of superoxide
dismutase (SOD) activity in serum and saliva of patients
with chronic periodontitis (CP).
In addition, the outcome of scaling and root planing (SRP)
with and without vitamin E supplementation was evaluated
in terms of changes in periodontal parameters
35
36. And they reported that adjunctive vitamin E
supplementation improves periodontal healing as well as
antioxidant defense.

38. Folic acid deficiency is characterized by lesions in cells with
rapid rate of renewal, which demonstrates the importance of
this vitamin in the synthesis of DNA.
Folic acid deficiency impairs immune responses and
resistance of the oral mucosa to penetration by pathogenic
organisms such as candida
38
39. A study (1997) reported series of human trials and
concluded that there was a significant reduction of gingival
inflammation reported after systemic or local use of folic
acid, when compared with placebo.

40. Alcohol is considered as one of the independent modifiable
risk factors for periodontitis.
Alcoholics are more prone to have a number of oral health
problems such as gingival infection, increased pocket depth
and loss of attachment, oropharynx cancer, caries, and tooth
loss
40
41. Several plausible mechanisms-
Amaral et al. (2011) reported that alcoholics have higher
levels of periodontopathic species in the subgingival
microbiota than non-alcoholics.

42. A recent study (2013) among African American males
reported that excessive alcohol use impairs the bactericidal
action of neutrophil and that periodontitis risk increases in

45. Periodontal diseases are more prevalent in addicts than in
the general population also having more cervical plaque on
one or more teeth.
A study (1996) found majority of addicts have a high rate of
plaque accumulation and calculus deposits resulting from
oral hygiene neglect, xerostomia and alteration in microbial
profile.

48. A study (2017) analysed results of 28 literatures to find an
association between poor oral health and substance abuse
and found that patients with substance abuse have greater

49. Patient compliance may be defined as the extent to which a
person’s behaviour coincides with medical or oral health
related advice.
It reflects a patient’s willingness to comply with preventive
or therapeutic strategies as set forth by his or her health care
provider.

50. The most meticulous and conscientious periodontal therapy
by a dentist is many a times rendered by patients
noncompliance to the maintenance therapy.
Stress full life events was the highly reported factor for non
compliance.*

51. A study (1991) reported that embarrassment, nervousness,
lack of time, practice location, beliefs/ideals, and personal
crises were not significant reasons for non-compliance
where as regular visit to dentist, cost and lack of perceived
need for periodontal therapy were the patients stated reasons
for non compliance.

57. Inadequate control of dental biofilm may result in
recolonization of the subgingival area by periodontal
pathogenic microorganisms, which could compromise the
results of the periodontal treatment
In periodontal maintenance, patients should participate
actively in the treatment and attending periodontal
maintenance appointments.

59. Bacterial plaque is the primary etiologic factor associated
with periodontitis. Therefore effective plaque removal on
daily basis by an individual is critical.
Many studies have demonstrated significant reductions in
probing pocket depths, attachment gains and, of course, in
gingival inflammation, with improvements in oral hygiene
alone.*

61. A study (2017) used pooled effect of fair OH versus good
OH and poor OH versus good OH on periodontitis found
odds ratios (ORs) of 2.04 and 5.01, respectively.
They measured oral care habits according to toothbrushing
regularity and dental visit frequency; pooled ORs of 0.66
and 0.68, respectively.
61
62. Further concluding that poor OH increases the risk of
periodontitis by approximately two- to five-fold compared
with good OH. Oral care habits, including regular brushing
and regular dental visits can decrease the risk of
periodontitis.

Apart from peripathogenic microflora, attachment loss is
influenced by many external modifying factors.
External modifying factors such as Smoking, Low SES,
Compliance, Poor Oral Hygiene, Irregular dental visits and
Unhealthy lifestyle increase an individuals risk of
periodontal disease.
