Abstract

Background:
Introduction: Radiographs have been widely used to determine morphological traits among genders in forensic odontology.
Aim: The study aims to determine the gender using an occlusal radiograph.
Objectives: Assessing the reliability of linear and angular measurement in the occlusal radiograph.
Materials & Methods: The study was conducted in the Department of Oral Medicine & Radiology in Namakkal District, after obtained approval from the institutional ethical committee with total sample size of 40 dentate subjects using an occlusal radiograph. After obtaining informed consent from patients, the study has been conducted.
Topographic occlusal radiographs were taken with help of an intraoral X-ray machine with ideal exposure parameters and all radiation protective precautions were carried out. Linear & angular measurement are measured attributing capital letters to the maxillary arch & small letters to the mandibular arch.
Statistical Analysis: The obtained data were analyzed using student t-test & Spss software version 22.0.
Results: In the present study among linear measurement molar (MM) is highly significant (p=0.012.) Among Angular measurements max CIA R (p=0.001), max PIB R (p=0.001), max MIC R (p=0.007), man pib r (p=0.017), man mic r (p=0.031), man pib l (p=0.028) are highly significant.
Conclusion: Gender can be determined by occlusal radiographs with greater reliability when linear measurement & angular measurements are performed.
