377. How to determine periodontal success – No bleeding on probing or establish clinical attachment? – The BEST CRITERION to evaluate the success of SRP is NO BLEEDING ON PROBING (since BOP indicates active inflammatory periodontal disease). Amount of attachment loss is the most important factor in the determination of a prognosis of a tooth with periodontal disease (more accurate than probing depth, tooth mobility, and presence of furcation involvement). à Long term prognosis
= plaque
– Attachment loss à Prognosis of tooth w/ periodontal disease
– Bleeding on probing à periodontal success
– Plaque à Long term prognosis

394. You have HIV+ pt you can do all of the followin except
a) treath with metronidozole
b) free gingival graft
c)prophylaxix to treat candidiasis
“Data from prospective controlled trials indicate that fluconazole can reduce the risk of mucosal disease (i.e., oropharyngeal, esophageal, and vulvovaginal) in patients with advanced HIV. However, routine primary prophylaxis is not recommended because mucosal disease is associated with very low attributable morbidity and mortality and, moreover, acute therapy is highly effective. Primary antifungal prophylaxis can lead to infections caused by drug-resistant Candida species and introduce significant drug-drug interactions. In addition long-term oral prophylaxis is expensive. Therefore, routine primary prophylaxis is not recommended (AIII).” 395. Permanent tooth with largest occlusal table – maxillary first molar.

396. Epithelium comes from the donor site – T

397. Dexterity- Something to do with flossing -> 5 brush and 8 floss. If lack of dexterity can’t do interproximal floss – T

398. Perio v/s endo abscess- pulp testing, lat percussion

399. Opaque porcelain function mask dark oxidized color – T
