Abstract

Background: Teeth have been used as the means for sex determination and for individual identification as they are resistant to various insults. Aims and Objectives: To determine the sexual dimorphism based on the linear measurements of mesiodistal dimensions of permanent maxillary central incisors and canines and maxillary inter-molar width. Setting and Design: Descriptive study. Materials and Methods: A total of 130 children, 65 boys and 65 girls of age between 11-14 years were included in the study. Impressions of the maxillary arch were taken with alginate, poured in dental stone and were allowed to set and then the cast bases were made with dental plaster. A digital vernier calliper was used for measuring the parameters. Mesiodistal width and maxillary inter-molar width were measured in millimetres. The data was statistically analysed with SPSS version 22.0 software using unpaired “t” test. Results: Mesiodistal width of the maxillary central incisors and canines were higher in boys than girls and inter-molar width was also higher in boys than girls. Percent sexual dimorphism was highest with maxillary right central incisor and least with maxillary inter-molar width. Conclusion: Mesiodistal dimensions and maxillary inter-molar width can be used as an aid for sex determination as an inexpensive and alternative method.
