Abstract
With high numbers of unidentified skeletonised remains recovered annually in South Africa and an increased number of edentate individuals being reported, the question arises as to whether tooth loss would result in craniofacial changes which might alter the accuracy of osteological analyses. Forty-five fixed landmarks together with sliding semilandmarks were collected from 229 white South African crania and were used to capture curve data pertaining to the basicranium, alveoli, zygomatic arches, nasal aperture and orbits. Geometric morphometric methods were employed to assess the effects of tooth loss on these structures. Although a number of effects were seen when the skull was analysed in its entirety, only the alveoli proved to be significantly affected when regions were analysed individually. Both upper facial height and palate shape were affected by tooth loss, which may influence various osteometric measurements and qualitative traits that are used during the assessment of ancestry and sex.
