Abstract

The patients treated at the Dental Hospital of Yonsei University during 1994-2000 were recalled for reexamination to evaluate the results of the treatment. Of two hundreds twenty three patients, one hundred patients were reexamined. A total of 105 teeth was included in this study. For each radiograph, 3 evaluators had to reach agreement before the case was assigned to one of the radiographic healing groups based on the criteria of Rud et al8). Radiogrphic success rate is 84.76% in this study and position of teeth and periodontal condition were statistically significant variables.
