Background:
Forensic odontology plays an important role in mass disasters, house fires, criminal deaths, identification of missing persons, and child abuse cases. Teeth are the most stable part of the human body and are resistant to thermal, mechanical, and chemical insults. The aim of this study was to evaluate the effectiveness of mandibular intercanine distance and mesiodistal width of mandibular first molar in gender determination.
Materials And Methods:
The study comprised 100 participants (50 males and 50 females) in the age group of 18-23 years. The mandibular impressions were made, and casts were prepared using dental stone. The intercanine distance and mesiodistal width of the right mandibular first molar were measured using digital vernier callipers. The data obtained was statistically analysed using SPSS software version 23.
Results:
The mean mandibular intercanine distance was found to be 27.2 ± 2.3 in males and 25.94 ± 1.76 in females (P = 0.03). There was no statistical difference in the mesiodistal width of the mandibular molar between males and females (P = 0.166). However, the mean mesiodistal width of males was higher when compared to females.
Conclusion:
Males have a greater intercanine width and mesiodistal dimension when compared to females. This result will be helpful in forensic medicine, anthropology, orthodontic treatments, and clinical dentistry.
