Measurements of mandibular radiomorphometric indices in Egyptian population at different ages using cone beam computed tomography: A cross-sectional study

Abstract

Aim: This research was conducted to correlate the mandibular radiomophometric indices with age in a sample of Egyptian population using cone beam computed tomography (CBCT). Materials and Methods: A total number of 318 CBCT scans of the Egyptian population were assigned to six age groups (53 per group) in a cross-sectional study using the simple random sampling method. Mandibular radiomophometric indices were assessed for each side and for each age group. Four quantitative indices were measured. The quantitative indices were mental index (MI), panoramic mandibular index superior (PMIS), panoramic mandibular index inferior (PMII), and panoramic mandibular index average (PMIA), which were measured on the CBCT cross-sectional cuts. Post hoc pairwise comparisons between the groups and both sides were done. Association and correlation between the indices and age were done. Results: There was a positive weak correlation between the indices and age. There was a statistically significant difference between panoramic mandibular indices. Conclusions: Age affects the mandibular radiomophometric indices. The mental index and panoramic mandibular indices increase with age.
