Evaluation of student readiness for clinical dental education at the end of preclinical education.

Abstract

This study examined results of a summative objective structured clinical examination (OSCE) at the end of preclinical periodontal education to identify deficient areas for dental students in patient care and to explore factors affecting the probability of passing the OSCE. The summative OSCE was administered to two consecutive cohorts, Classes A (class of 2024; n1=134) and B (class of 2025; n2=129). The questions for each station in the OSCEs were available to both classes 1 week before the OSCEs. Descriptive statistics were used to identify deficient areas. The multiple logistic regression model was built to predict the probability of passing the OSCE based on the cohort, gender, and the practical and written examination scores. Fifty-one (38%) students in Class A and 66 (51%) students in Class B completed the OSCE by passing all stations. Students undergoing remediation showed deficiencies in demonstrating how to detect tooth mobility, performing periodontal probing, drawing the healthy positive bony architecture and the mucogingival junction, and using a universal and a Gracey 13/14 curette. The probability of passing the OSCE was significantly correlated with Class B (p=0.035) and the practical examination score (p=0.03) while not associated with gender (p=0.53) and the written examination score (p=0.11). Students showed deficiencies in assessment skills at the end of preclinical education. The study findings suggest that the implementation of the OSCE at the conclusion of preclinical education would be beneficial since the written examination score might not accurately reflect student readiness for clinical patient care.
