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.
