Students prepared upper first molars on the simulation models within 30 minutes just before and after 1-year clinical courses, and their product was evaluated in order to examine significance of the course regarding preparation skill. The check points were convergence angle, occlusal clearance, surface roughness, amount of reduction (measured with weight loss of plastic tooth) and total impression by raters. In addition, four less-skilled students were selected and given a supplemental course consisted of training on the simulation model at the beginning of clinical course. At the end of the course, effect of training was evaluated. The results were follows : 1. There were no differences in convergence angle between before and after clinical course, but big differences in rating grades of total impression, that is grades after the course were remarkably higher than those before the course. 2. Through the supplemental course, preparation skill in convergence angle and rating grades of total impression was considerably improved and the higher level was maintained until after the course. In other words, the supplemental course was very effective in teaching tooth preparation. 3. There were no significant differences in other factors, occlusal clearance, surface rouglaness and amount of reduction, in any stages and students.
