Effect of the endodontic status of the tooth on experimental periodontal reattachment in baboons: a preliminary investigation.
The effect of the endodontic status of the tooth on periodontal reattachment after the raising of a mucogingival flap was studied with the use of 48 teeth in four old baboons. Root canal therapy was performed on 26 front teeth. Tubliseal, AH26, N2, and Diaket were used as sealers with gutta-percha. The pulps of 5 teeth were exposed and left infected; 17 teeth with intact pulps served as a control. The teeth and their surrounding structures were studied histologically for reattachment with new cementum formation 2 to 17 days, 1 to 2 months, and up to 1 year after the operation. In the teeth examined 1 month postoperatively or more, if epithelium had not covered the denuded surface, new cementum was present, regardless of the endodontic status.
