complications +OAC, pericoronitis

Question 1

teeth most at risk for OAC

Answer 1

maxillary molars

obv in close proximity to the sinus

Question 2

sinus pneumitization

Answer 2

increases risk of OAC

sinus line extended below the hard palate

Question 3

allogenic bone graft

Answer 3

An allogenic bone graft is done using human bone, but unlike other types of bone grafts, the bone is not harvested from the patient receiving the graf

Question 4

xenograft + examples

Answer 4

a tissue graft or organ transplant from a donor of a different species from the recipient.

collagen
gelatin film
bioguise / bio-oss

Question 5

immediate tx vs delayed

general

Answer 5

immediate = 
1. soft tissue flaps 
local like buccal flap or distant like tongue 
2. bone grafts 
3. allogenous grafts 
- fibrin glue 
- dura 

delayed =
1. xenografts
-collagen
-gelatin film
-bioguide 
2/ synthetic materials 
3. other techniques
- GTR
- prolamin gel
-splint

Question 6

single most imp thing

Answer 6

recognitino

have them breathe through nose with resistance - created valsalvs meanuver and see if area bubbles - if communication exists

Question 7

pericoronitis

Answer 7

anatomy that favors
betweeen crown and overlying gingiva

A marked inflammatory response over a partially impacted tooth and is best thought of as a “Low Grade Infection”

Results from a “favorable” anatomic environment and high bacterial burden which creates a “trap door effect” for debris and bacteria to overgrow unopposed by hygiene practices

May be associated with any tooth that is partially impacted (meaning there is no possibility of full eruption into a functional position) exposure exposure of only part of the dental crown

Third Molar teeth are the most common site for pericoronitis in the OMS clinic

• think about it like a low grade infection

Question 8

treat acute pericoronitis?

Answer 8

While extraction of the tooth or elimination of the soft tissue “trap door” eliminate the source of the problem, doing so doing acute pericoronitis can result in severe tracking of infection/pathogens to unfavorable areas

***Active (acute) pericoronitis however is best managed over the short term with elimination of the bacterial load (ie scaling), topical antimicrobial (chlorhexidine) and/or 1 week course of oral abx (penicillin, amox or clindamycin)

Question 9

mouth rinse rx?

Answer 9

Chlorhexidine oral rinse 0.12%
Disp: 16oz or (32oz)
Sig: 15ml swish for 30sec and expectorate BID x 7days

Question 10

if spread pericoronittis could go?

Answer 10

lateral pharynx

medial ramus
