Summary

Aim: To assess the reliability of age estimation in Egyptian adolescents and young adults using mandibular third molar stages of calcification, based on the Demirjian method, on CBCT scans.

Methodology: 145 CBCT scans for the mandibular left posterior region were collected from the database of the maxillofacial radiology clinic of the faculty of dentistry at Cairo University. The scans were then analyzed using Planmeca Romexis software viewer version 4.6.2.R. The mandibular left 3rd molars were evaluated to determine the calcification stage of each of them based on the modified Demirjian method. According to the assigned calcification stage, the dental age was determined, and then the mean ± SD for each calcification stage was calculated and compared to the chronological age in terms of mean difference and mean absolute error. The correlation between the calculation stage and chronological age was analyzed, and the probability for an individual to be 18 years of age or older in each stage was calculated.
