Abstract
Background and objectives: Determination of the age of majority is a major problem in forensics. This study aimed to evaluate the usefulness of Demirjian’s stages of teeth development in estimating the age of majority from the left mandibular molar among a sample of the Egyptian population
Methods: A prospective cross-sectional study included a sample of 134 digital panoramic radiographs of participants aged 15-26 years. The left lower third molars were analyzed using Navegatium DICOM viewer software for the medical sector. e version 1.10.0.0 applicable on Microsoft. The effectiveness of Demirjian’s stages was assessed by using accuracy, sensitivity, specificity, positive (LR+) and negative (LR-) likelihood ratios, and positive and negative predictive values
Results: The test showed better specificity for stage H (90.91% for males, and 63.64% for females), and better sensitivity for stage G (98% for males, and 95.16% for females) for adult age. The accuracy of the test was (85.25% for males and 72.60% for females) in stage H, and (93.44% for males and 87.67%for females) in stage G.
Conclusion: Demirjian’s stages G and H are fairly reliable method for estimating the age of majority among Egyptians.
