Dimorphism in dental tissues: sex differences in archaeological individuals for multiple tooth types
Dimorphism in dental tissues: sex differences in archaeological individuals for multiple tooth types
Objectives
Dimorphism in the dentition has been observed in human populations worldwide. However, research has largely focused on traditional linear crown measurements. As imaging systems, such as micro‐computed tomography (micro‐CT), become increasingly more accessible, new dental measurements such as dental tissue size and proportions can be obtained. This research investigates the variation of dental tissues and proportions by sex in archaeological samples.
Materials and Methods
Upper and lower first incisor to second premolar tooth rows were obtained from 30 individuals (n = 300), from 3 archaeological samples. The teeth were micro‐CT scanned and surface area and volumetric measurements were obtained from the surface meshes extracted. Dental wear was also recorded and differences between sexes determined.
Results
Enamel and crown measurements were found to be larger in females. Conversely, dentine and root measurements were larger in males.
Discussion
The findings support the potential use of dental tissues to estimate sex of individuals from archaeological samples, while also indicating that individuals aged using current dental aging methods may be underaged or overaged due to sex differences in enamel thickness.
