Accuracy of Periodontal Probing Depth and Calculus Detection Through the use of the Kinoshita Nissin Periodontal Dental Model.
Abstract: Dental education is a continually evolving process. This study seeks to develop evidence-based practices for the instruction of dental students to accurately probe periodontal pockets and detect dental calculus. The purpose of this study was to evaluate the effectiveness of the Kinoshita Dental Model (KDM) as a pre-clinical training tool for pre-doctoral education in periodontal probing ... read moreand calculus detection. Prior to this study, students at Tufts University School of Dental Medicine (TUSDM) had been trained primarily through lecture in techniques for periodontal pocket probing and calculus detection. The KDM was specifically modified by the authors of this study to facilitate hands on instruction of probing depth measurement and calculus detection. Study participants were second year TUSDM students. Participants were given a hands-on lecture and workshop on correct techniques for periodontal probing and calculus detection using one of two KDM models. Three workshops were given. In each workshop participants received a KDM with different simulated gingiva. The three preclinical groups were trained on KDM models with translucent gingiva, opaque gingiva, or both translucent and opaque gingiva models. At the end of each workshop students were tested on opaque gingiva KDMs to determine their accuracy in both periodontal probing and calculus detection. The pre-clinical results of this study indicate that students preformed comparably on each model type with no statistically significant differences between groups for probing depth measurement. Significance was reported between groups for the total number of correctly identified surfaces of calculus however, no pair of groups could be identified as exhibiting a significant difference once accounting for more stringent statistical measures with Bonferroni correction. Preclinically, the opaque group performed better than the group trained with both translucent and opaque gingiva (p<0.05) for calculus detection. Clinical results showed no statistically significant differences between groups for mean probing depth values or the number of correctly identified surfaces for calculus detection. However, Generalized Estimating Equation (GEE) analysis showed a significant difference (p<0.0001) in students' ability to properly identify sites without calculus as compared to sites with calculus for all groups. This study brings us insight as to the effectiveness of each KDM as a teaching tool for periodontal probing and calculus detection as well as student performance on these tasks in a clinical setting.
