Abstract
Background: Regarding the new dental licensing regulations in Germany (AOZ), this study evaluated the effectiveness of two different digital tooth preparation validation systems in comparison to traditional faculty feedback. Methods: Participants were randomly divided into groups: Faculty Feedback (FF: n = 33), PrepCheck® (PC: n = 32) and Dental Teacher™ (n = 32). Students had the task to prepare tooth 16 for a retentive full-cast crown. Preparations could be repeated as often as desired. Feedback was provided either by faculty staff or by digital validation systems only. Exams were conducted and graded by two independent and experienced examiners. A survey was performed to evaluate the assessment concepts. Results: No statistical difference in examination performance between groups could be observed. Nevertheless, the survey showed participants preferred consulting the faculty staff rather than the digital validation systems. Students preferred practising with DT rather than with PC. Conclusions: Although both classical and digital methods showed comparable results regarding the preparation examination performance, direct feedback by the faculty staff is still appreciated by the students. A combination of both methods is mandatory since demonstration and advice by the teacher is needed. However, digital tooth preparation validation systems are predestined for free practice sessions, providing self-assessment.
Highlights
Over the last two decades, digitisation has increased enormously in everyday life.Improved computing power and graphic visualisation have allowed the implementation of various innovations
Statistical analysis did not expose the difference in the performance within groups (Kruskal–Wallis and Dunns multiple comparison test; p < 0.05) (Figure 2)
Assuming grade “D” as a minimum requirement for passing the exam, the preclinical examiner did not rate below this grade, whereby 23 participants (22%) failed the exam according to the clinical examiners rating
Summary
Improved computing power and graphic visualisation have allowed the implementation of various innovations. This development affects many areas of modern healthcare, aiming for higher efficiency, facilitated clinical decision-making and quality assurance. The demand for digital systems in dental education has evolved [3]. Two basic approaches of digital dental education systems are available: digital evaluation systems, which provide feedback on the students’ preparation (e.g., PrepCheck® (Dentsply Sirona© , Bensheim, Germany)) Dental. Regarding the new dental licensing regulations in Germany (AOZ), this study evaluated the effectiveness of two different digital tooth preparation validation systems in comparison to traditional faculty feedback. Feedback was provided either by faculty staff or by digital validation systems only. Exams were conducted and graded by two independent and experienced examiners
