Abstract

The aim of this study was to evaluate the impact of a contemporary preclinical technique skills course on early dental student performance in a preclinical operative course. Ivorine teeth prepared for Class I resin restorations by the Classes of 2020 and 2021 in one U.S. dental school were evaluated in this study (N=184). Ivorine teeth were prepared during the first practical exam of the operative dentistry course. Students in the Class of 2021 had been enrolled in a contemporary technique skills course a semester prior to the operative dentistry course, while students in the Class of 2020 were not. The preparations were randomly evaluated by three calibrated and blinded faculty members using magnification loupes, an explorer, and a periodontal probe to evaluate external outline form, internal form, depth, and margin following an established rubric. The results showed that students in the Class of 2021 (who had taken the technique skills course) performed significantly better than students in the Class of 2020 for all criteria evaluated (p<0.05). In this study, incorporation of the preclinical technique skills course improved student performance in the subsequent operative dentistry course.
