Resumen

Objetive: To compare majority age estimation according to Demirjian's method and Cameriere's third molar maturity index using cone-beam computed tomography in patients who attended the Maxillofacial Diagnostic Institute during 2014-2018, Lima-Peru. Material and Methods: A cross-sectional and analytical analysis was performed evaluating 492 lower third molars corresponding to 38 and 48 teeth. Patients included were between 12 and 23 years-old and were of both sexes. Data obtained were analyzed with a double entry frequencies distribution table. Sensitivity, specificity tests, and plotting on a ROC curve were selected to assess the methods capacity to estimate the majority age. Results: Sensitivity values for Demirjian's and Cameriere's indexes were 0.80 and 0.70. Specificity values were 0.87 and 0.93, respectively. The AUC for Demirjian's and Cameriere's indexes were 0.84 (0.79-0.88) and 0.81 (0.77-0.86) respectively and the Delong test p-value was > 0.05. Conclusions: There was no difference on majority age estimation accuracy according to Demirjian's method and Cameriere's third molar maturity index using cone-beam computed tomography.
