Effect of a Pilot Preclinical Incentive Program on Dental Students’ Performance on a Clinical Competency Exam

Abstract

The aim of this study was to investigate the effect of a pilot preclinical incentive program on dental students' performance on a clinical competency (mock board) exam at Midwestern University College of Dental Medicine-Arizona. To assess the effect of preclinical grade incentives in a program called SUCCEED, scores from a clinical competency exam administered during the fall quarter of the fourth year were compared between the graduating classes of 2014 and 2015 (pre-SUCCEED curriculum) and the graduating class of 2016 (post-SUCCEED curriculum). The study hypothesized that the class participating in the SUCCEED program, with its incentives for greater preclinical preparation and practice, would score higher than the other classes on the exams. The results showed that the endodontics and periodontics pass rates and test scores from the Class of 2016 were higher than those from the Classes of 2014 and 2015; the prosthodontics pass rates were similar; and the operative dentistry pass rates and test scores were lower than the Classes of 2014 and 2015. While the results of two of the four subsections of the competency exam showed an improvement in clinical performance for the Class of 2016, the operative dentistry test scores for that class were less than expected. Based on the increased number of operative dentistry procedures performed in preclinical simulation and the clinic, the authors conclude that the competency exam should not be the only measure to evaluate success of the SUCCEED program.
