Covariation between dental development and mandibular form changes: a study combining additive conjoint measurement and geometric morphometrics

Popis výsledku v původním jazyce

Studies have suggested that dental development substantially influences the variation of mandibular morphology and growth in primates. As a contribution to the methodology of such studies, we introduce a novel approach to quantifying the covariation between teeth and mandible. This was done showing fluctuations in the magnitude of this covariation within a sample of modern human mandibles at different postnatal ages. Dense CTderived mandibular surface meshes of 73 females and 71 males, ranging in age from birth to adulthood, were processed by methods of geometric morphometrics. Each specimen?s deciduous and permanent teeth were rated for mineralization stage. Form-space principal component analysis of the morphometric data was used to produce a singlemetric variable that best explains mandibular-form variation. This variable was then used to quantify the developing teeth, all together, through the use of the additive conjoint measurement method.
