1. It has been decided to perform osseous surgery on the maxillary right quadrant of a patient. This surgery will involve modification of the bony architecture of the periodontally involved teeth. The objective(s) of osseous surgery include:
a. periodontal pocket reduction
b. regeneration of periodontal tissues lost to periodontitis
c. gingival tissue morphology which mimics physiologically contoured alveolar bone
d. a and b
e. a and c
2.What is the objective of flap design for regenerative surgery?
a. To remove the maximum amount of gingival tissue to eliminate pocket depths
b. To preserve the maximum amount of gingival tissue and papilla to cover the materials placed for regeneration
c. To increase the zone of attached gingiva
3. In designing your flap, vertical incisions should be placed:
a. In the center of an interdental papilla.
b. At the mid-radicular surface of a tooth.
c. At the line angle of a tooth.
4. Which ONE of the following in NOT considered a displaced flap design?
a. Apically positioned flap.
b. Lateral sliding flap.
c. Coronally positioned flap.
d. Modified Widman flap ??
5. If your periodontal surgery sextant has a very narrow band of facial keratinized gingiva, your surgical technique will most likely include:
a. Intra-crevicular incisions
b. Reverse bevel incisions
c. External beveled incisions???
6. Which antibiotic therapy would be your first choice for a patient suffering from necrotizing ulcerative gingivitis/periodontitis (NUG/NUP)?
a. Atridox (doxycycline in biodegradable polymer)
b. Arestin (minocycline microspheres)
c. PerioChip (chlorhexidine gluconate in gelatin chip)
d. Oral Metronidazole tablets??????
7. Which of the following terms is defined as the reshaping of the alveolar process to achieve a more physiological form with the removal of supporting bone?
a. osteotomy
b. osteoconduction
c. ostectomy
d. osteoinduction
e. osteoplasty
8. Bone morphogenic proteins, whether in active or inactive forms, can be found in which of the following bone grafting materials?
a. alloplasts
b. demineralized freeze dried bone allograft
c. autogenous grafts
d. b and c
e. all of the above
9. You have decided to place your patient on low dose doxycycline (Periostat®). The intended mechanism of action of this medication is:
a. The suppression the arachidonic acid pathways
b. Bactericidal to a selected group of periodontal pathogens
c. To inhibit the activity of collagenases, particularly those produced by polymorphonuclear leukocytes (neutrophils, PMN).
d. None of the above
10 . During the course of periodontal therapy, plaque retentive sub-gingival carious lesions should be corrected:
a. During the hygienic phase
b. After the re-evaluation appointment
c. After completion of the periodontal treatment
d. All restorative needs must be completed before the start of the periodontal treatment.
11 Healing after scaling and root planing will consist largely of:
a. formation of new cementum
b. new connective tissue attachment
c. formation of a long-junctional epithelial attachment
d. periodontal ligament regeneration
Following the hygienic phase of periodontal therapy, the re-evaluation appointment is scheduled _____________ after scaling and root planing.
a. 2-4 weeks
b. 4-6 weeks
c. 6-8 weeks
d. 8-10 weeks
