QUESTIONS AND ANSWERS SURE A+
✔✔osteoradionecrosis is more common in ? - ✔✔the mandible.
- probably because of the richer vascular supply ot hte maxilla and the fact that the
mandible is more frequently irradiated.
- osteoradionecrosis is necrosis of bone, produced by ionizing radiation.
✔✔Name of pathology: Patient returns 48-72 hours after extraction with pain and fetid
odor?
TX: (3)? - ✔✔fibrinolytic alveolar osteotitis (dry socket or local osteitis)
tx is to irrigate extraction site and treat with iodonform gauze and eugenol.
✔✔Patient presents with a blood clot after extraction (post surgical sequela) Most likely
a ___ clot.
Tx:? (3) - ✔✔liver clot
remove with curette, apply pressure, and reassess
✔✔if a PERMENANT tooth is avulsed,
1. scrub clean?
2. place in milk of hanks balanced salt solution? - ✔✔do not scrub clean, will kill cells
yes place in milk of hanks balanced salt solution
✔✔t/f; traumatic ulcer can occur after tooth extraction? ill fitting dentures - ✔✔true and
true
,✔✔t/f? prophy teeth after extraction to reduce plaque and bacteria? - ✔✔false before
extraction allow better healing of tissue during post surgery healing
✔✔If a patient takes asprin after reviewing thier medical history, they may have
excessive ____ after extraction - ✔✔excessive bleeding
✔✔A patient taking coumadin requires a tooth extraction. What test are needed? -
✔✔PTT and INR
✔✔Normal PT/INR - ✔✔PT: 10-13s (greater than or equal to 2.5)
INR: <1.2 (less than or equal to 3.5)
✔✔After SRP, you would typically find reduciton in inflammation and ___-___mm
probing depth (pocket reduction) - ✔✔1-2mm
✔✔A 6-7mm pocket with continued BOP depsite good oral hygiene and root planning
would result from ______ or ____ - ✔✔retained subginval bacteria or calculus
✔✔The best way to detemrine if a ptients periodontal condition is stable is if there is
______. - ✔✔no increase in pocket depth
✔✔What are the two most significant factors that influence the course of periodontal
disease ? - ✔✔furcation involvement and pocket depth
✔✔Best (inital and most effective ) treatment of ANUg is ? - ✔✔SRP (debridement)
✔✔t/f: ANUG can cause foul(bad breath) - ✔✔true
✔✔name type of treatment: treatment is SRP and place gingival graft and is V shaped ?
- ✔✔Stillmans cleft
✔✔The common goal of flap surgery is toe access ___ for ___ to allow pocket
elimination - ✔✔access roots for debridement to allow pocket elimination
✔✔healing of what type of epithelum occurs after raising a flap? - ✔✔long junctional
epithelium
✔✔The normal width of kertatinized gingiva in the mandibular anterior region is ? -
✔✔3-4mm
✔✔Drugs like Naproxene, penicllin, and Asprin ________pocket depth. Tetracyclines
(arestin) _____ pocket depth in conjunction with SRP - ✔✔do not increase pocket depth
, can increase pocket depth in conjunction with srp
✔✔Measurement in millimeters of the depth from the gingival margin to the epithelial
attachment in unhealthy gingival tissue is the ____? - ✔✔pocket depth
✔✔distance from the free ginval margin to the cej of the tooth measures? -
✔✔recession
✔✔Furcation involvement:
Class I tx? Pocket depth?
Class II tx? Pocket depth?
Class III tx? Pocket depth?
Class IV tx? Pocket depth?
Class V tx? Pocket depth? - ✔✔class I: treated with scrp, less than 3mm depth
class II; SRP followed by Guided tissueregernation with bone graft and membraine
barrier to prevent epithelial migration into the furcaito and allow bone migration,
idfferntiaion, an matureation of the area. At least 3mm depth
Class III/IV: success is limited, tunnerlizaiton is used to created a tunnel throug hthe
furcaiton to allow an interproximal brush to clean th efurcation. Greater than 2mm with
Nabers probe. Goes through the enter width of the tooth so no bone is attached to the
angle of the furcation
✔✔Furcation involvement
Measured with what instrument - ✔✔A loss of alveolar bone and periodontal ligament
fibers in the space between the roots of a multirooted tooth
Nabers probe
✔✔Furcation involvment with worst prognosis? (1)
Best prognsisis (2)
limited prognosis:(2) - ✔✔grade 4: worst
1/2 best
