The analysis and feedback from the performance of pre-clinical operation skills tests for clerkship in School of Dentistry, National Taiwan University in 2022

Abstract

Background/purposeThe simulated pre-clinical operation skill test (PCOST) is part of the objective structured clinical examination (OSCE) and designed for clinical practice using manikins, physical typodonts, and instruments in the laboratory. This study tried to evaluate the influencing factors of the PCOST results for dental students. Materials and methodsThe 32 5th-year dental students of the dental school of National Taiwan University (NTU) joined the PCOST. The contents of PCOST included two specialties: operative dentistry (OD) and prosthodontics (PS). The examination content of OD was tooth 36 mesio-occluso-distal (MOD) cavity preparation, and that of PS was crown preparation and temporary crown fabrication of tooth 11. Several factors including the gender, age, and dental student admission ways (with or without the skill tests) were evaluated. Each scoring item was calculated. The students also filled the feedback questionnaire about the examination questions and suggestions for the PCOST. ResultsFor both OD and PS, there were no significant differences in the mean PCOST scores between male and female dental students, between two groups of dental students with or without the skill tests in the admission process, and among three different age groups of dental students. According to the feedback questionnaire from the participated dental students, they were satisfied with the PCOST. ConclusionThe PCOST is a good simulated examination in clinical practice. However, we still need to collect more PCOST data and feedback to revise the guideline of the PCOST, and to promote the performance of clinical works of dental students.
