HEAS member Gerhard Weber starts a new FWF Project to study the 3D morphology of human postcanine teeth
HEAS member Gerhard Weber starts a new FWF Project to study the 3D morphology of human postcanine teeth. Petra Simkova will be employed as PostDoc, Jana Pfneiszl will start a PhD in the project. In this project we undertake the first comprehensive 3D study of human teeth, more precisely of the tooth crowns of canines, premolars, and molars from the upper and lower dentition. We will also include milk teeth. Despite the long history of dental research in anthropology and medicine, progress in studying the three-dimensional geometry of teeth has only been made recently. How the 3D shape and size of individual tooth types are related to each other, how they vary between different human populations, and which individual regions of these teeth show more or less variation remains largely unknown. This project fills the gaps in our knowledge on human dental anatomy, provides comparable data, and lays the foundations for future work to unravel the associations between teeth and genes. We have defined four major aims: 1) Investigate the 3D shape and size variation of the upper and lower dentition in a geographically diverse sample of modern humans, 2) study the shape variation in different tooth regions, namely those regions that touch each other during chewing and those which do not touch, 3) examine the 3D shape relationships between…
