Morphometric evaluation of Bizygomatic distance and maxillary sinus width as dimorphic tool- A CBCT study

Abstract

Objectives: The objective of this study is to determine the age prediction on the basis of Bizygomatic distance, intermaxillary distance, Antero-Posterior diameter and maxillary sinus width. The bizygomatic distance and maxillary sinus width is also studied as dimorphic tool in relation to gender determination. Materials and Methods: This is prospective study of 202 study subjects which was carried out in Department of oral medicine and radiology using Care stream 9000cc Cone beam computed tomography (CBCT) machine. All the measurements were taken from series of axial sections of Cone beam computed tomography (CBCT) of head and Paranasal sinuses (PNS) images using DICOM viewer. Results: There was no significant (p>0.05) difference in the study parameters among the age groups. It was found that only Bizygomatic distance was significantly (p=0.01) different between male and female all other parameters were statistically non significant (P>.005). Conclusion: It was concluded that bizygomatic distance is a strong dimorphic tool for sex determination by cone beam computed tomography.
