Forensic odontology is a challenging and interesting branch of forensic science that has evolved as a new ray of hope assisting forensic medicine. It involves among other applications the administration of dental sciences in the identification of deceased individuals. Nowadays, radiology has an indispensable role in human identification based on the anatomy and depending mainly on comparing anatomical landmarks in antemortem and postmortem records.The dento-maxillofacial radiology plays an important role in the field of dental forensics, studying the radiographs and allowing for evaluation of further details (Nicopoulou-Karayianni et al. 2007&Rathod et al. 2017). Sex determination is a subdivision of forensic odontology,that has an indispensable role in human identification especially when the information related to the deceased individuals is unavailable. Radiographsplay a remarkable role as an aid for sex determination, as they provide several measurements without a flesh barrier. Accordingly, radiographic imaging methods are generally preferred by forensic scientists as they offer various morphological information that can be analyzed and used for gender differentiation (Karayianni et al. 2007, Divakar et al 2015, Uppal et al. 2018) Many researchersstudied sexual dimorphism in various populations by analysis of different anatomical structures using radiographs of the maxillofacial region. Teeth dimensions, dental arch analysis, paranasal sinuses, foramen magnum dimensions, craniofacial analysis, mandibular ramus measurements and inferior alveolar canal location were proven to be effective indicators of sexual dimorphism in different populations (Oliveira et al. 2009, Angel et al. 2011, Indira et al. 2012, Abu-Taleb and El Beshlawy 2015&Demiralp et al. 2019)
