3. DISCLAIMER
• All the materials (literature) that I have put in this presentation
that might change according to time because this Is new virus
and everything is under trial.
• Purpose of this presentation is to spread awareness among our
collogues about COVID 19
• THANK YOU

4. INTRODUCTION
• Covid 19 pandemic it was initiated in 20019 from the city of
Wuhan China, shows flue like symptoms and mainly spread
by close contact and by droplet infections.
• Some authors claim that salivary gland it is reservoir of this
viruses and it spread by Aerosol generation. Some of authors
claimed that the mouth is like graveyard for this virus, and in
oral cavity tongue is the most common site where virus can
stay longer in the oral cavity.

5. • As a prosthodontist it is routine work to prepare full coverage
crown, full mouth rehabilitation, mouth preparation etc. this
all procedure generates more amount of aerosol which is
harmful for the dentist, patients, dental assistant and for the
society also.
• We are the peoples who is more close to the covid 19 so it is
important to know details about this virus and there
management.

6. TERMINOLOGIES
• VIRUSES:- an infective agent that typically consists of a nucleic
acid molecule in a protein coat, is too small to be seen by light
microscopy, and is able to multiply only within the living cells of a
host.
• EPIDEMIC:- a widespread occurrence of an infectious disease in
a community at a particular time.
• PANDEMIC;- prevalent over a whole country or the world.

7. BACKGROUND
• Corona virus term was coined in 1968
• Corona= Crown like structure
• 1975= family Corona viridae
• 2005= sub family
A. Corona virus.
B. Torovirus.

23. COVID 19 IN DENTISTRY
• DENTISTS ARE MORE PRONE TO THIS VIRUS
BEACAUSE OF
• Work into the mouth
• Chances of salivary contamination
• Aerosol generation
• Salivary gland is reservoir of this virus
• Tongue is the part of oral cavity where we they can get
attached for more periods of time.

24. MANAGEMENT IN DENTAL
CLINIC
• TYPES OF DENTAL CARE
1.EMERGENCY 1.URGENT
1.NON-
ESSENTIAL

25. WHAT IS AN EMERGENCY?
• In dentistry, an emergency is a potentially life-
threatening condition that requires immediate
treatment, including:
1. • oral-facial trauma
2. • cellulitis or other significant infection,
especially if compromising the patient’s airway
3. • prolonged bleeding
4. • pain that cannot be managed by over-the-
counter medications

26. WHAT IS URGENT CARE?
• In dentistry, urgent care is the management
and treatment of conditions that require
immediate attention to relieve pain and/or
risk of infection, including:
1. • severe dental pain from pulpal
inflammation
2. • pericoronitis or third-molar pain
3. • surgical post-operative osteitis, dry socket
dressing changes
4. • abscess or localized bacterial infection
resulting in localized pain and swelling

27. 5• tooth fracture resulting in pain, pulp exposure or causing soft
tissue trauma
6• dental trauma with avulsion/luxation
7• final crown/bridge cementation if the temporary restoration is
lost, broken or causing gingival irritation
8• biopsy of a suspicious oral lesion or abnormal oral tissue
9• replacing a temporary filling in an endodontic access opening
for patients experiencing pain
10• snipping or adjusting an orthodontic wire or appliance piercing
or ulcerating the oral mucosa
11• treatment required before critical medical procedures can be
provided

28. WHAT IS NON-ESSENTIAL CARE?
• In dentistry, non-essential care is the provision of routine or
non-urgent procedures, including:
1. recall examinations and routine radiographs
2. • routine dental cleanings and preventive therapies
3. • orthodontic procedures other than those to address acute
issues (e.g. pain, infection, trauma)
4. • extraction of asymptomatic teeth
5. • restorative dentistry, including treatment of asymptomatic
carious lesions
6. • cosmetic dental procedures, including teeth whitening

29. PROSTHODONTIST POINT OF VIEWS
• Procedures that can be performed:
1) Removable denture fabrication :
2)Fixed prosthodontics :
• No crown preparations to be done
Fractured prosthesis can be removed
Already prepared teeth: Either Bisacrylic chairside temps or lab
fabricated heat cure
Already fabricated fixed prosthesis: has to be sterilized as
described below and can be cemented using permanent cement

30. • Recementation of dislodged crowns/bridges
• • Missing anterior tooth/teeth can be
replaced a temporary
• Maryland bridge or Essix appliance.
• • Missing posteriors:
• Removable denture to avoid occlusal plane
discrepancy and to restore function.

31. PRECAUTIONS TO BE TAKEN:
• Impression trays
• Avoid using plastic trays; Metal trays to be water rinsed,
dried, packed and autoclaved before and after use
• Ultrasonic cleaners:
• washing under running tap water followed by judicious use of
ultrasonic cleaners is recommended.

32. • Impression disinfection
• Alginate : to be disinfected using
• 1% sodium hypochlorite solution.
• Quaternary ammonium compounds, glutaraldehyde based;
alcohol based.
• Elastomeric impressions
• 1% Sodium hypochlorite solution,
• Quaternary ammonium compounds, glutaraldehyde based

33. • Wax rims and wax bites
• disinfected using an sodium hypochlorite spray; "spray-wipe-
spray" technique; wax bites can be enclosed in a sealed plastic
bag for the proper contact time.
• Acrylic appliance disinfection
• Povidone Iodine or 1% Sodium hypochlorite are preferred.
Avoid storing prostheses in a disinfectant before insertion
Instead rinse thoroughly after disinfection and store acrylic
items in diluted mouthwash until inserted.
• Fixed prosthesis disinfection: Immersion in Cidex (alkaline
glutaraldehyde) or 1% sodium hypochlorite.
• Gypsum casts: Difficult to disinfect. Microwave irradiation of
the casts for 5 minutes at 900 W does give high level
disinfection of the gypsum casts.

34. IMPLANT SURGERY
• Implant surgeries should be postponed as far as possible.
However, osteotomies for implant site preparation maybe
possible in select clinical situations.
• FOLLOWING PROCIDURES CAN BE PERFOMED
• Bone expansion: In cases with softer bone (D3,D4) and narrow
ridges, bone expansion procedures can be accomplished using
expansion screws or convex ossteotomes. This may lead to
thinning of the labial bony wall, which can be augmented by
performing a GBR (Bone grafting) procedure.

35. • Immediate placements: Most immediate implant placements
do not require too much osteotomy site preparation. Apical
preparation for achieving primary stability can be achieved
using the same protocol explained above.
• Indirect Sinus Lifts: Can be performed using concave
ossteotomes followed by bone augmentation.
• Ridge augmentation and socket grafting procedures can be
performed as always.

36. AVOID:
FOR IMPLANT DENTISTRY
• 1.Avoid mandibular anterior cases
• 2. Speed> 100 rpm: the smoke can cause aerosol even in
absence of saline
• 3. No Piezo surgical devices
• 4. No autogenous grafting using trephine/ACM/piezo:
• 5. Complex surgical procedures

37. CAUTION
• Before going for any procedure take proper history proper
screening and proper PPE.
• It can be dangerous for any dentist if they are comes in
contact with any patients.
• If you are suspect then go for home quarantine
• Can take Hydroxychloroquine as a prophylactic measures
• Stop your practice if u are suspected and try to go for
screening.

39. ADA GUIDELINES

40. CONCLUSION
As we are the dentist then we are the person who is most close
to mouth of any patients.
And we are more prone to infection then other one. So the
knowledge about this virus is very important so that we can
prevent the spread of this virus.
We must be constantly aware of infectious threats that may
challenge the current infection control regimen, especially in
dental practices and schools of dental medicine.
