Abstract
Background:
Gender determination is one of the prime parameters in forensic identification. The feasibility of the nonreactive, mineralized part of teeth to resist mutilation and to survive deliberate, accidental, or natural change has led forensic experts to focus on the teeth as a possible source as forensic data in cases of fragmentary and mutilated human remains.
Aim:
The aim of this study is to determine gender using odontometric diagonal measurements of permanent maxillary and mandibular teeth.
Objectives:
To measure and evaluate sexual dimorphism by odontometric diagonal measurement of teeth.
Materials and Methods:
The study sample included a total of 80 maxillary and mandibular dental casts obtained by alginate impression from 40 participants (20 males and 20 females) in the age range of 19–35 years selected from the Central Indian population. Mesiobuccal-distolingual (MBDL) and distobuccal-mesiolingual (DBML) measurements of the right permanent maxillary and mandibular teeth excluding third molars were taken separately. All the measurements were taken using a Digital Vernier Caliper. Data were analyzed using discriminant function analysis.
Results:
It is found that the diagonal measurements are significantly greater in males than females. The highest percentage of overall accuracy rate of maxillary MBDL is followed by maxillary DBML, mandibular MBDL, and mandibular DBML. All the values of the mean tooth dimension of MBDL were greater than DBML. The overall accuracy rate of maxillary MBDL is 97.2% and mandibular MBDL is 95.2%. The overall accuracy rate of maxillary DBML is 96.56% and mandibular DBML is 94.21%.
Conclusion:
Diagonal measurements of teeth can be used for sex determination. The most significant variable is found to be MBDL measurements of maxillary and mandibular second premolars. It is the strongest predictor for gender determination.
