Ambient occlusion and PCV (portion de ciel visible): A new dental topographic metric and proxy of morphological wear resistance

MA Berthaume, J Winchester, K Kupczik - PLoS One, 2019 - journals.plos.org
Recently, ambient occlusion, quantified through portion de ciel visible (PCV) was introduced
as a method for quantifying dental morphological wear resistance and reconstructing diet in
mammals. Despite being used to reconstruct diet and investigate the relationship between
dental form and function, no rigorous analysis has investigated the correlation between PCV
and diet. Using a sample of platyrrhine and prosimians M2s, we show average PCV was
significantly different between most dietary groups. In prosimian, insectivores had the lowest …
