 note = {application/pdf, This clinical study examined, on clinical success, the influence of excess pealers and/or overextended gutta-percha points beyond the radiographic apex or root surface. The long-term follow-up was also done on excess sealers and overextended gutta-percha points. The cases (root canals) examined were the same cases as reported previously in the Matsumoto Shigaku (the Journal of Matsumoto Dental Callege Society) (Vol. 6), entitiled "Clinical success of endodontically treated teeth." The results were as follows: 1. 92.8% (220 canals) out of the cases without excess sealers and overextended gutta-parcha points, 89.8% (53 canals) out of the cases with excess sealers, 84.3% (129 canals) out of the caseh overeutended gutta-parcha points were considered successful. Statistical analysis of healing at the cases without excess sealers and overextended gutta-percha points and the cases with overextended gutta-percha points yielded significance (α=0.02). 2. Excess sealers were absorbed as time went by, and almost disappeared at the end of 2 years postoperatively. There were no relationships among size of excess sealers, absorbed rate of exsess sealers and age of the patients. 3. The fracture of overextended gutta-percha points occurred on 7 of 153 cases in the follow-up period. The overextended gutta-percha points of all these 7 cases were fractured at the radiographic apex root surface. All of them were successful. There was a tendency that the longer the overextended gutta-parcha points were the more fractured. It seemed that the fracture of overextended gutta-percha points were caused by the physiological movement of teeth.},
