Odontometric Analysis of Permanent Maxillary First Molar For Sex Determination
Keywords:Odontometrics, gender determination, maxillary molar.
Introduction: Sex determination from skeletal remains forms part of archaeological and medicolegal
examinations. Teeth, being the hardest and chemically the most stable tissue in the body are an excellent
material in living and non-living populations for anthropological, genetic, odontological and forensic
Objective: The aim of this study is to assess and evaluate the sex discrimination potential of permanent
maxillary first molar.
Materials and method: 100 subjects (47 males and 53 females) were selected from outpatient department
of a private dental institution, with the age group of 10-40 years. The mesiodistal and buccolingual crown
dimensions, cusps dimensions and diagonal dimensions of permanent maxillary right and left first molar
were measured from the study casts with digital Vernier caliper. Sexual dimorphism in the left and right
maxillary first molar was also calculated using formula. The data obtained were subjected to statistical
analysis using paired and unpaired t?test.
Conclusion : Maxillary first molar shows significant sexual dimorphism and can be used as an adjunct along
with other accepted procedures for sex determination.
