Abstract

AIMS: To assess the sex discrimination potential of permanent maxillary molar crown widths and cusp diameters.

MATERIALS AND METHODS: Measurements were made on plaster casts of 200 individuals of known sex (100 males, 100 females, aged 12-21 years). Eight parameters were measured on the first and second maxillary molars with a digital caliper [buccolingual, mesiodistal, mesiobuccal-distolingual and distobuccal-mesiolingual crown widths and cusp diameters (hypocone, protocone, paracone, and metacone)]. The percentage of sexual dimorphism for each parameter was calculated. Discriminant function analysis was used to determine the accuracy of sex determination for each molar separately and both the molars taken together.

RESULTS: The highest sexual dimorphism was shown by protocone in the first molar and hypocone in the second molar. Furthermore, the sex determination accuracy was highest when the first molar was taken alone than when the second molar or the first and second molars were taken together.

CONCLUSION: Based on this study, odontometric measurements of maxillary molars provide low to moderate sex determination accuracy.

Keywords: Crown widths; cusp diameters; odontometric; sexual dimorphism
