Abstract

 Objectives: The objective of the present study is to determine the age on the basis ofbizygomatic 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 151 study subjects which was carried out in Department of oral medicine and radiology using Carestream 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: The study population consists of 151 study subjects aged between 6 and 17 years having49.7% male and 50.3% females.The maxillary sinus width in right side of male and female was statistically significant (p<0.05). The mean maxillary sinus width in right side is higher in males (25.6 mm)than females(23.9mm).Maxillary sinus width (right & left), maxillary sinus height (right & left), intermaxillary distance and bizygomatic width were significantly associated in all age groups(P<.005). On the basis of strong positive correlation shown by pearson correlation, it was concluded that age plays an important role in determination of maxillary sinus width, maxillary sinus height, intermaxillary distance and bizygomatic width. The mathematical equations derived from linear regression analysis helps in age determination. However age prediction by maxillary sinus width (right & left), maxillary sinus height (right & left), intermaxillary distance and bizygomatic width was strongly significant i.e on the basis of above parametrs age can be predicted with high accuracy. Conclusion: As maxillary sinus width (right & left), maxillary sinus height (right & left), intermaxillary distance and bizygomatic width was strongly significant (P value<.05). It was concluded that in paediatric population, all the maxillary parameters can be used as strong dimorphic tool for sex determination by cone beam computed tomography.
