Orthopantomography and use of Mandibular Indices for the Evaluation of Gender Distribution in Navi Mumbai Population - A Retrospective, Single Blind Study

Introduction: The study of forensic sciences often leaves the expert to draw conclusions from any and every material available in determining identity deceased. initial step identifying a person is determine their gender based on adult skeleton. human skeleton displays sexual dimorphism, which skull most dimorphic providing an accurateness 92%. However, certain situations where may not be found intact, mandible plays vital role. mandible's thick covering compact bone helps keep it exploding during mass tragedy. Dimorphism specific mainly reflected its shape size. also easily radiographed linear measurements mandibular rami as seen OPG are useful indices for determination. 
 Aims: To examine efficacy measures such maximum ramus breadth, height, minimum condylar coronoid body length gonial angles right left side gender.
 Materials methods: 110 digital OPG’s (55 males, 55 females) Navi Mumbai population were obtained retrospectively reputed dental college hospital. taken using Xtropan 2000 machine, 10x12 PSP plates, exposure parameters 75 Kvp, 8 mas, 13 sec, KODAK CR 7400 digitizer. Master View 3.0 software was used desktop computer measure ramus's width thickness. Maximum Ramus height lowest breadth rami, well condyle bone, sides mouth, all measured. Using statistical formula, substituted estimated.
 Result: We IBM SPSS v 21.0 social do our study. p0.05 deemed statistically significant, with 5% margin error 20% error, giving 80 percent power. In group, 51 men expected while 49 females anticipated females, 6 predicted males.
 Conclusion: This research shows that tool gender, panoramic imaging yielded best accurate measures. There considerable dimorphism chosen – subpopulation, combination factors demonstrated accuracy 91.81 helpful
