Abstract
This study examined whether tooth extrusion can be induced by experimental periodontitis. Five mongrel dogs served as the subjects. A metal cap was set on both sides of the lower 3rd premolar, and a bridge type splint used for measuring the amount of tooth extrusion was splinted on both sides of the lower 2nd and 4th premolars. In the 3rd premolar of the experimental site, experimental periodontitis was induced by dental floss ligature. The periodontal tissue on the contralateral side was kept healthy. The amount of tooth extrusion was measured once a week by using silicone rubber impression paste and determining the distance between the upper side of the metal cap and the lower side of the apparatus on the impression. Then clinical parameters were examined.<BR>The results obtained were as follows:<BR>1. The experimental side showed significant extrusion compared with the control side.<BR>2. Tooth mobility was grater on the experimental side than the control side. The increase in tooth mobility was correlated with the amount of tooth extrusion.<BR>3. On the experimental side, a remarkable increase in pocket depth and loss of attachment were found at the end of the 1st week, but there were few changes afterwards.
