In preclimcal restorative technique courses, traditional evalution methods established by dental educators were used with student produced specimens and interviews related to the performance of the task. Although defined criteria were present, instructors tended to evaluate subjectively and there appears to be a need for improving the method of evaluation. Self-assessment is a new and important aspect in educations. Students should be trained and expected to critically evaluate their work Only then can the instructors and students contructively discuss deficiencies. The purpose of our study was to determine if students can become proficient in self-assessment of ClassII MO-shce type inlay casting preparations. The authors developed a new format, which designated twenty-nine aspects for use in evaluating tooth preparations a grading scale was used for each criterion overdone (cut too much), good, underdone (cut too little) 97 dental students (4th grade) prepared a right maxillary first molar of a plastic tooth in a manniqm for Class II MO-slice casting inlay at campletion of the exercises of the first and second half of the preclimcal perative dentistry laboratory course, and evaluated their own work according the new format 7 facult members selected 24 out of the 97 cavities at random, and also evaluated these with the format The authors compared differences in student understanding and improvements from the first student evaluation with the second evaluation. The following results were obtained. 1 Student self-evaluation of MO-shce type inlay preparation was higher than the evaluation by faculty Student self-evaluation of cavity preparations were similar to that of the faculty after the first half of the course. 2 After the first half of the course, student prepared cavities were cut too much at the occlusal fissure and the groove evaluation showed the axio-pulpal line angle slightly and there were irregularities in the cavity walls This improved after the second half of the course. 3 Student cavity preparations of the proximal part did not improve with experience There were differences in the evaluation of the proximal part among instructors. The intent of the criteria-evaluation format is to provide begming students with an orderly and systematic approach to cavity design and a mechanism for discussion with laboratory instructors.
