Cervico-Incisal measurements of Incisors, Cuspids, and Molars for Gender Estimation:A Pilot Study in Western Uttar Pradesh

Abstract

Background: Dental forensic anthropology is a specialized field within forensic den????stry that focuses on examining the variations in dental morphology and measurements of human teeth across different ????me periods (both prehistoric and modern) and geographical regions (including ethnic influences). Objectives:o check whether there is sexual dimorphism in cervico-incisal dimensions of incisors, cuspids and molars. Methods: Cross sectional study conducted in 60 patients, aged 25-60 years from daily hospital OPD at Aligarh. Impressions of both the maxillary and mandibular arches were taken using irreversible hydrocolloid-alginate material. To prevent any distor????on, the impressions were promptly cast with type IV dental plaster. The resul????ng study models were then measured using a digital Vernier caliper (resolu????on 0.01 mm) (Aerospace) to ensure precise data collection on study casts. The data thus obtained was tabulated and subjected for further sta????s????cal analysis using SPSS 20.0 (Microso???? Corpora????on Inc., Chicago, IL, USA). Results The le???? mandibular first molar with SDI of 134.5%, and poten????ally other mandibular measurements, could be highly reliable markers for sex determina????on in forensic inves????ga????ons. Conclusion The present data underscores that male den????????ons are consistently larger than female den????????ons, with the mandibular teeth especially le???? mandibular first molar demonstra????ng the most significant differences.
