Quantification of dental macrowear using 3D occlusal surface topographic measurements in deciduous and permanent molars of children.

ABSTRACT:

Objectives

Childhood paleodietary reconstruction via dental macrowear analysis is limited in part by available methods to measure dental macrowear. We describe a method to quantify dental macrowear progression (in both deciduous and permanent molars) using a handheld intraoral scanner and two 3D occlusal topographic measurements. We assess the agreement of our macrowear proxies with an established qualitative wear scoring system and their relationship to age.

Material and methods

We scanned 92 well-preserved dentitions of immature individuals from the medieval cemetery of St. Pölten in Lower Austria using an intraoral scanner. Two measurements were made on the resulting mesh files-the relative flat surface area in % of the occlusal surface (RFSA%) and the mesial interior slo
