Perceived confidence of dental students and new graduates in performing tooth extractions-An exploratory study.

Abstract

The ability to perform uncomplicated tooth extractions is a core clinical skill in undergraduate dental education. The aim of this study was to evaluate pre-extraction assessment skills of dental students and interns and explore their self-perceived confidence in performing these tooth extractions. A cross-sectional survey investigated the self-perceived confidence to perform the extraction for a set of eight expert-rated cases. The participants were dental students at three different stages, that is, in Years 4 and 5 of the Bachelor of Dental Surgery (BDS) programme and interns. The participants were asked to rate the difficulty level of each of the eight tooth extraction cases. The self-perceived confidence of the participants to perform extraction of each was also explored. Finally, the participants were asked to identify the main reason for the perceived lack of confidence. A total of 199 responded to the survey, yielding a response rate of 94.7%. The effect of grade of extraction (the expert rating of cases) and stage of education on difficulty ratings was assessed using a mixed three stage of education × 4-grade ANOVA, with response (Difficult = 1, Easy = 0) as the dependent variable. The results showed that there was a correlation between the stage of education and grade of extraction and affected the self-perceived confidence of the participants. Gender showed a significant impact with females categorizing significantly more cases as difficult. A three-way contingency table (counts of each confidence-level response by stage of education by expert rating of cases) suggests a statistically significant association between the three factors. Most participants identified limited clinical exposure as the main reason for their perceived lack of confidence. The findings of this study show that a majority of the participants were able to recognize tooth extraction cases which were beyond the scope of their training stage with females reporting a lower confidence. Increased clinical exposure to a wider range of tooth extraction cases with varying levels of difficulty may contribute to improving the self-confidence of undergraduate dental students and interns.
