Abstract

Objective:The present study is intended for properly assessing, comparing, and evaluating the contemporary measurements of gonial angle using digital panoramic radiography. In addition, this research evaluates the importance of mandibular gonial angle in gender determination.Materials and Methods:Technically, this is a retrospective cross-sectional study, where the study sample was composed of 590 (295 males and 295 females) patients undergoing digital panoramic radiography in the College of Dentistry in University of Science & Technology of Fujairah, Fujairah, UAE . These patients had been prescribed panoramic radiographs based on different factors. As a generally adopted procedure, bilateral gonial angle measurements were carried out, results were recorded, and their predictability as a determinant of gender was assessed. ANOVA and t-test procedures were utilized for statistical analysis of the collected data.Results:The analysis of the present study confirmed a statistically significant difference between the right and left sides of the gonial angle in both genders. Further, the mean comparison exposed a variation between males and females, based on gonial angle values; females have a statistically significant higher mean angle values than males. Based on the analysis, the present study concludes that this difference between males and females from both sides suggests that the gonial angle helps in sex identification.Conclusion:It has been concluded that gender significantly influences the gonial region and has great potential to be used as a forensic tool in gender determination. Digital panoramic radiography is a good study tool and it can be used to determine the morphology of the mandible.

Highlights

IntroductionFor the proper assessment of the mandibular and maxillary vital structure, practitioners most commonly and frequently advise panoramic radiographs (OPGs)
The study explicitly revealed that females had statistically significantly higher gonial angles than males
Summing up the above discussion revealed that the outcomes of the current work are in line with the previous relevant literature; using values of gonial angles is significantly important and helpful in the determination of gender

Summary

Introduction

For the proper assessment of the mandibular and maxillary vital structure, practitioners most commonly and frequently advise panoramic radiographs (OPGs). This is considered the all-inclusive approach for imaging the number of different dental disorders in one film. If the head positioning is kept constant and standardized, a suitable duplicability in terms of vertical and angular variables for group comparisons is obtained [20 - 23] It has been documented in the earlier studies that irrespective of the fact that the horizontal measurement is not much reliable, angular measurement is still carried out in the OPG process with significant reliability
