Age related gingival recession

# Age-related gingival recession can be best treated by:

A. Gingivoplasty

B. Pedicle graft

C. Free gingival graft

D. No treatment

The correct answer is D. No treatment.

Gingival recession increases with age, the incidence varies from 8% in children to 100% after the age of 50 years. This has led to some investigators to assume that recession may be a physiologic process related to ageing. 

Tooth most affected by gingivitis

 # Facial surface of which tooth is most affected by gingivitis?

 A. Upper first molar

 B. Lower first molar

 C. Lower central incisor

 D. Lower premolar

The correct answer is A. Upper first molar.

Facial surface of upper first molar and lingual surface of lower central incisors is most affected by gingivitis. This is due to close proximity to opening of salivary ducts.

Life saver shaped gingival enlargement of Marginal Gingiva

 # Life saver shaped gingival enlargement of marginal gingiva is called:

 A. Stillman's cleft

 B. McCall's festoons

 C. Widow peaks

 D. Craters

The correct answer is B. McCall's festoons.

The term McCall's festoons has been used to describe a rolled, thickened band of gingiva that is usually seen adjacent to the cuspids when recession approaches the mucogingival junction.

Stillman clefts are apostrophe shaped indentations extending to marginal gingiva. They are usually present on facial surface. 

Craters are bony defects or concavities found in interdental areas.

Widow peaks are pseudo piling up of gingiva when failed to remove bony discrepancies at gingival line angles during osteotomy procedures. These are peaks of residual cortical bone left out during horizontal grooving at the facial/palatal/lingual line angles. 

Radiographic finding of Aggressive periodontitis

 # One of the radiographic finding of Aggressive periodontitis is arc shaped bone loss extending from:

A. Distal surface of the second premolar to mesial surface of second molar

B. Distal surface of the first premolar to mesial surface of first molar

C. Mesial surface of the second molar to distal surface of the first premolar

D. Mesial surface of the first premolar to distal surface of the second premolar

The correct answer is A. Distal surface of the second premolar to mesial surface of second molar

- Localized Juvenile Periodontitis is characterized by distribution of lesions in the first molars and incisors with least destruction in the cuspid-premolar area whereas in Generalized Juvenile periodontitis, there is generalized involvement of teeth.

- Vertical bone loss around incisors and molars in otherwise healthy teenagers is diagnostic of Localized juvenile periodontits.

- There is an arc shaped bone loss extending from distal surface of second premolar to mesial surface of second molar creating a mirror image type of bone loss which is characteristic of Juvenile periodontitis.
