Resumen:
Objectives: Sexual estimation of human remains is of great importance for bioarchaeologists and forensic anthropologists. If the skeletons are damaged, fragmented or mixed, dental metrics are a useful procedure to obtain reliable information otherwise lost. Since dimorphic patterns tend to vary among populations, specific formulae must generally be calculated for different samples in order to obtain accurate results. Recently, ten discriminant functions and logistic regression equations including the buccolingual and mesiodistal diameters of permanent canine crowns and necks were developed for sex estimation with a sample of 115 individuals died between 1895 and 1936 that belongs to the Collection of Identified Skeletons of Coimbra (CIAS, University of Coimbra, Portugal). They successfully estimate sex between 78.9 and 85.1%. The aim of this study was to test if those formulae offer adequate results in a geographically-related sample from the Roman (I-III century AC) cemetery of Ossonova, Faro, Portugal.Methods: Canines from 32 individuals, previously sexed through a traditional multiregional approach (based on pelvic and cranial analysis), were considered for this research. The measurements were recorded with a fine point caliper, specially designed for odontometric studies; only teeth without pathologies, intense wear or taphonomic effects were considered.Results: One discriminant function and two logistic regressions offered values of correct allocations higher than 75% for males and females separately; they mostly included neck measurements. This fact indicates that phenotypic variation in human samples from similar proveniences could be an important factor that influences the data obtained.Conclusions: The findings obtained show that canine odontometrics is a powerful tool for sex estimation and increase the amount of data obtained for bioarchaeological purposes. However previous testing of the methods must be done when applied to samples different from those used to generate them. Moreover, the importance of incorporating neck measurements in the anthropological-forensic protocols is highlighted.
