Evaluation of Sexual Dimorphism through Linear Odontometric Measurements in a Maharashtra Cohort: A Cross-sectional...

The most resilient structures to mechanical, thermal, and chemical changes are teeth. Both metric and nonmetric techniques may be used on the teeth to determine dental gender. Several odontometric investigations were conducted in various Indian demographic groups. The Maharashtrian population was not studied for sexual dimorphism using linear odontometric analysis.

This study aims to determine sexual dimorphism using linear odontometric analysis in a sample of the Maharashtrian population.

One hundred and sixty individuals, including patients and students, participated in cross-sectional research. Dental alginate was used to take impressions of the maxillary and mandibular arches from undergraduate students and patients at our institution after the participants gave their written permission. Dental stone was then used to pour the castings. A digital caliper calibrated to 0.01 mm was used to measure the mesiodistal (MD) and buccolingual (BL) dimensions of every tooth, with the exception of third molars, on the castings, and all the measurements were recorded.

Male canine BL and first premolar MD dimensions in the maxillary arch are substantially larger than those of females. The mandibular first premolar MD measures and the maxillary lateral incisor BL measurements were significantly bigger than the mandibular arch when comparing the two arches. Using MD and BL measures, the Maharashtrian population's overall sex determination accuracy rate was 73%.

The most accurate markers of sexual dimorphism in the Maharashtrian population are maxillary canines and maxillary first premolars. These results draw attention to population-specific differences that may have an impact on anthropological and forensic research.
