Relationship of Age, Gender, and Height with the Anthropometric Radiographic Indices of the Mandible in 20-50-year-olds of Iranian Race

The mandibular bone, similar to other bones in the human body, has a number of effective anatomical features that the use of radiographic images of these features can be effective in various findings, such as forensic dentistry. The present study aimed to estimate age, gender, and height by measuring the anthropometric radiographic indices of the mandible in 20-50-year-olds of Iranian race.

This cross-sectional study was performed on 100 people (50 female and 50 male) who were referred to the Orthodontics Department of Ilham Dental School in 2018. The required information was extracted and recorded from patients' panoramic radiographs. Statistical analysis was performed using descriptive statistics, t-test, and SPSS (version 22) software.

The results of this study showed no significant difference between any of the studied variables with age (P>0.05). However, a significant difference was observed between mandibular width, mandibular height, gonial angle, mandibular canal, and the superior-inferior position of the mandibular foramen with gender and height (P<0.05). Moreover, no significant difference was found between the location of the mental foramen and the posterior and anterior position of the mandibular foramen with height (P>0.05). In addition, although no significant difference was seen between the antegonial angle and gender, the antegonial angle had a significant relationship with height (P<0.04).

There is a significant relationship between skeletal variables and gender and height, and it may be possible to determine the gender and height of individuals by evaluating radiomorphometric indices.
