Abstract

Abstract: Purpose/Objective: The effectiveness of different curriculum types has long been debated by dental educators aiming to provide the best education possible to their students. This study aimed to evaluate the effect of curriculum type (hybrid problem‐based learning [PBL] vs. traditional) on National Board Dental Examination (NBDE) part I and II pass rates Methods: A retrospective cohort study was conducted with a hybrid PBL cohort and traditional cohort. NBDE part I and II pass rates for the two cohorts were acquired, along with demographic and scholastic variables. Pass rates, scholastic variables, and demographic variables were compared using two‐sample t ‐tests and chi‐square tests. Associations of the variables with pass rates were analyzed using logistic regression. Significance was set at 5% Results: No significant differences in pass rates for NBDE part I and II were observed between the cohorts. Cumulative dental school grade point average (GPA) was found to be an independent predictor of success for NBDE part I (odds ratio (OR): 1.40, 1.24–1.59 for 0.1 point intervals) and II (OR: 1.34, 1.18–1.52 for 0.1 point intervals), ( p < 0.01). DAT biology sub‐score was found to be predictive of success for NBDE part I (OR: 1.58, 1.14–2.19), ( p = 0.01) Conclusions: No significant difference in NBDE part I and II pass rates between the cohorts was found. Dental school GPA was the most predictive variable for success on NBDE part I and II. These findings may be helpful considerations as institutions assess the structure of their school curricula.
