 note = {Objective: To standardize examiners using a dental model, we developed a dental model and conducted a study that found the model was feasible and effective for student practice. However, it remains unclear whether the skill of measuring probing depth (PD) in this model correlates with the skill of measuring PD in patients. Thus, this study was designed to clarify this point and to determine the accuracy rate of a skilled examiner. Material and Methods: Study 1: Fifty-one students measured PD in patients with more than 4 teeth having a pocket equal to or deeper than 4 mm and PD in the model. On the same day, their instructor remeasured PD in these patients. Study 2: Ninety- nine students and 11 Certified Periodontists measured PD in the model. Results: Study 1: The accuracy rate of students measuring patients’ PD equal to or deeper than 4 mm and PD in the model showed a significant positive correlation. Study 2: Based on the receiver operating characteristic curve analysis, the accuracy rate equivalent to the skill level of Certified Periodontists was found to be 84.7%. Conclusion: Standardization of examiners was confirmed with this model. The standard accuracy rate of skilled examiners was found to be 85%.},
