[Statistical study of endodontically treated teeth by undergraduate students from 1979 to 1989]

In clinical education in dentistry, it is very important and significant that the undergraduate students themselves treat the patients. According to the rapid progress of dental science, the complexity and the high degree of the quality of education increase more and more, so that it is a requisite to make our efforts to enrich the quality of the practice at all times. In this paper, we investigated and statistically analyzed the result of 3,359 cases (test cases: 304, general cases: 3,055) which were treated endodontically by the undergraduate students of Tokyo Medical and Dental University in the four classes of 1979, 1982, 1986 and 1989. Both the number of the treated cases and the patients decreased year by year. Only the patients above sixty years old showed a tendency to increase in number. The result of the test cases was not always representative of the result of the general cases. If the clinical instructors for the undergraduate students grasp the detailed results of this study, we can expect that they can guide and train the undergraduate students more effectively.
