Abstract
Purpose
The objective of this study was to assess the impact on diagnostic accuracy and Kappa values improvement during the three-phase training and calibration process for MIH/HSPM.
Methods
Thirty dentists were calibrated as examiners for diagnosis of Molar Incisor Hypomineralization (MIH) using Ghanim’s index. The whole process was divided into three phases. Phase 1: three meetings with the dentists for the first diagnosis training and calibration (sessions 1a and 1b); phase 2: for a period of 1 month, the dentists started practicing MIH/HSPM diagnosis in the Basic Health Units and an online follow-up group was created to discuss cases and resolve doubts; phase 3: two meetings with the dentists for the second calibration (sessions 2a and 2b). A webpage with educational material was prepared as support during the whole process to improve the dentists’ skills in diagnosing MIH/HSPM. The examiners’ responses were compared to a gold standard and the Kappa value was obtained.
Results
The average clinical criteria kappa value of the examiners was 0.76 ± 0.19 for the first calibration and 0.93 ± 0.07 (p < 0.05) for the second calibration. For the eruption criteria, the average kappa value was 0.89 ± 0.14 for the first calibration and 0.98 ± 0.08 for the second calibration. Extension criteria had an average kappa value of 0.59 ± 0.15 during the first calibration and 0.75 ± 0.14 during the second calibration.
Conclusion
This study demonstrated that the methodology used was an effective tool for improving the diagnostic accuracy of MIH/HSPM.
