Abstract

Abstract Introduction Updating the method for evaluating suturing and scaling skills in dental education has attracted relatively little attention and there is no consensus to what should be assessed and how. The purpose of this study was to investigate the applicability of the Objective Structured Assessment of Technical Skill (OSATS) method for these two basic skills, the possible association between the scores and demographic factors, and the level of satisfaction of residents with this method. Methods All six periodontics and three oral medicine residents were recruited by census method and video-recorded while performing a simple interrupted suture, a figure eight suture and scaling on a model. Then, the videos were evaluated independently via a checklist and a global rating scale (GRS) by two expert raters. Agreement between raters and residents’ satisfaction were evaluated. Correlation between demographic factors of participants and scores was also assessed. T-test and linear regression analysis were used. Results There was no significant difference between the scores based on the views of the two raters for each of the checklist (ICC = 0.99, CI = 0.96–0.99, P < 0.001) and GRS (ICC = 0.97, CI = 0.86–0.99, P < 0.001). Linear regression showed no correlation between gender and scores but periodontics major and higher year of education showed correlation with higher scores. Conclusion Considering the excellent agreement between raters in using both the checklist and GRS components of OSATS, and satisfaction of 88% the residents with this method, it seems to be able to provide a reliable assessment.
