size, shape, and location of PAFs according to age cohort, gender, and ethnicity

What is it about?

proximal attrition facets are usually located on the upper half of the crown proximal aspect; in each tooth, the mesial facet is more lingually positioned and the distal facet is more buccally positioned; the majority of the facets are subrectangular in shape; the size of the facets tends to increase in an anteroposterior direction (from premolars to molars); and facet size and location are age- and sexdependent and ethnicity-independent.

interproximal attrition is a dynamic, long-term process and needs to be considered in many clinical scenarios.
