Abstract
Different studies have evaluated the mandibular anthropometric parameters pertaining to gender prediction in different races. In this study, mandibular anthropometric measurements are evaluated for gender prediction in Iranians over the age of 20. Eight anthropometric measures were evaluated in 120 Iranian adult cadavers from 2011 to 2012, and the relationship between these variables and their changes with gender were examined. Collected data was analysed using SPSS version 13 by means of descriptive analysis, ROC curve, cross tabulation and discriminant analysis. There was no significant difference in the mandibular angle between the two genders. The characteristics holding the most value for gender prediction were symphysial height and minimum ramus breadth in those between 20–34 years old, mental angle in those between 35–49 years old and symphysial height in those older than 50. Overall, measured accuracy of the mandibular bone in sex prediction was between 80% and 95%. Our results showed that measuring the mandibular parameters can identify gender with a high rate of accuracy.
