영문 초록

The purpose of this study was to investigate the resorption potential in human permanent teeth by analyzing the frequency and the degree of root resorption as revealed by routine intraoral roentgenograms. The following conclusions were obtained: 1) The distribution of root resorptions was as follows; a) 65.3 per cent were no root resorption. b) 7.0 per cent showed questionable root shortening. c) 25.2 per cent were definite root shortening. d) 2.5 per cent showed very severe resorption. 2) The order of susceptibility of teeth to resorption in this study was consistent with other studies. 3) The maxillary teeth showed a much higher incidence (52.2 per cent) than the mandibular teeth (17.1 per cent) 4) The sex ratio of the sample in this study was 1.3 female to 1 male.
