Contribution of dental tissues to sex determination in mod- ern human populations.

Earlier studies have shown that elements of the human permanent dentition are sexually dimorphic. The aims of this study are to determine the degree of sexual dimorphism in the dental tissue volumes and surface areas of mandibular canines and to explore its potential for reliable sex determination. Method: The teeth included in this study (n569) were selected from anthropological collections from Spain, South Africa and Sudan. In all cases, the sex of the individuals was known. The teeth were scanned and three-dimensional (3D) measurements (volumes and surfaces areas) were obtained. Finally, a dsicriminant function analysis was applied. Results: Our results showed that sexual dimorphism in canine size is due to males having greater amounts of dentine, whereas enamel volume does not contribute significantly to overall tooth size dimorphism. Classification accuracy of the multivariable equations tested on slightlyworn teeth ranged from78 to 90.2% for the crossvalidation, and from71.43 to 84.62% for the hold-out sample validation. When all functionswere applied together, the sexwas correctly assigned 92.30% of the time. Conclusions: Our results suggest that the 3D variables from mandibular canine dental tissues are useful for sex determination as they present a high degree of dimorphism. The results obtained show the importance of 3D dental tissue measurements as a methodology in sex determination, which application should be considered as a supplemental method to others.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/journal article1096-8644https://doi.org/10.1002/ajpa.23447https://onlinelibrary.wiley.com/doi/10.1002/ajpa.23447https://pubmed.ncbi.nlm.nih.gov/29460327/restricted access340.6CaninesDentineDimorphismEnamelMicrotomographyAntropología biológicaMedicina legal (Medicina)Odontología (Odontología)2402 Antropología (Física)3203 Medicina Forense
