A Computer-Assisted Training Approach for Performing and Charting Periodontal Examinations: A Retrospective Study.
Journal of Dental Education 2018 January
The aim of this study was to retrospectively investigate the development of a model-based, computer-assisted training approach for performing and charting periodontal examinations in a dental clinic in Germany. The study was initiated in summer semester 2013 and repeated in two consecutive semesters (S1: 44 students, S2: 48 students, and S3: 61 students) because technical features were introduced (S2: feedback and time control; S3: input control). In each semester, new dental students who had never performed periodontal examinations participated. Students were divided into two groups and received intense training at different time points. Agreement levels were calculated at baseline, after the first group received training, and after the second group received training. Comparisons were also made among the semesters. All 153 enrolled students in the three semesters participated. The results showed that probing depth accuracy significantly decreased in S1 from baseline to training completion (79.9% to 74.5%), and the probing depth accuracy significantly increased in S2 (76.1% to 78.9%) and S3 (77.2% to 82.3%). The students who received intense training at a late stage of the tutorial showed greater improvement, especially in the case of S3. Small changes in accuracy were observed for recession (S1: 94.5% to 96.1%; S2: 93.8% to 93.9%; S3: 95.4% to 96.6%). Accuracy for furcation involvement improved significantly in S1 (46.1% to 52.0%), S2 (46.8% to 59.7%), and S3 (44.2% to 58.3%); the improvements occurred when the students received intense training. The time taken for periodontal examination decreased significantly for S2 (23.6 to 14.2 min) and S3 (25.7 to 13.9 min). This study found that when feedback was provided, the students' periodontal examinations improved in accuracy and duration.
