| Abstract | ||
| Aim: The aim of this study is to identify sex and estimate age by measuring the maxillary sinus dimensions and bizygomatic distance using CBCT. Subjects and Methods: Using 180 CBCT scans 90 males and 90 females divided into 3 age groups; Group I: 18-29 years, Group II: 30-41 years, and Group III: 42-60 years; medio-lateral (ML), superior-inferior (SI), anteroposterior (AP), antero-lateral angle (ALA), volume (Vol.) of both right (R) and left (L) maxillary sinuses (MS), intermaxillary distance (IMD), and bizygomatic distance (BZD) were measured and compared. Discriminant function analysis and linear regression analysis were performed for sex identification and age estimation respectively. Results: A significantly higher mean values of right and left ML in males than females (p=0.001) and (p=0.002) respectively. Mean values of AP, SI, Vol. of both sides and BZD were significantly higher in males (p=0.000). ALA revealed high insignificant mean values in females. IMD revealed high insignificant mean value in males. No significant difference between age groups regarding MS measurements, ALAR and BZD. But ALAL and IMD showed a significantly lower value in Group I in comparison to Group II and III (p=0.018) (p=0.000) respectively. In terms of discriminative ability, SIR had the highest overall sex prediction accuracy 69.44%. Linear regression analysis for age prediction revealed that IMD had the highest overall prediction R2 = 0.143.Conclusions: The use of maxillary sinus dimensions and BZD may be valuable for sex determination. Conversely, these variables revealed poor results for age estimation. | ||
