Dental students' self-reported confidence level in restorative crown and bridge procedures: A UK quantitative study

Introduction
Graduating confident students who can flourish and develop in their future career is an important outcome of dental education. The aim of the study was to gain an insight into students' self-reported level of confidence in restorative crown and bridge procedures, highlighting in which stage of the process students have the highest and lowest confidence, depending on the level of supervision required.

Materials and methods
Fourth and final year students (n = 85) were invited to complete a 71-item closed questionnaire specific to self-reported confidence based on the level of supervision required in stages of crown and bridge procedures. Clinical activity for each student from their portfolio system was collected. Non-parametric tests, specifically the Mann–Whitney U-test was used to analyse the continuous non-normal data.

Results
A response rate of 65% was obtained. Final year students were more confident in crown and bridge procedures than fourth year students. Fourth year students were more confident in bridges, whilst final year students were more confident with crowns. Majority of students expressed “average confidence requiring minimal supervision” in crown and bridge procedures. An association between clinical activity, confidence and year of study was noted. Gender was not strongly associated with confidence. Stages in crown and bridge procedures were noted where students lacked confidence.

Conclusion
The study highlighted areas in which students were most and least confident in crown and bridge procedures. A positive relationship between clinical activity in crown and bridge procedures and student self-confidence has been noted for both years, though slightly higher in the bridge procedure for fourth year students. We attribute this to the fact that fourth year students had recently completed their bridge competency assessment. Upon graduating, final year students still require supervision and reported average confidence in certain aspects of crown and bridge procedures, namely occlusal, bevel and axial reduction.
