Dental micro-wear

Tooth micro-wear results from abrasion between the tooth and food as well as attrition between the teeth themselves.

The micrometric traces accumulate continuously and vary significantly depending on the functions of the dental facet considered and the composition of the bolus.

This eco-indicator provides information on the interindividual, interpopulational and interspecific variability of diets in the weeks preceding the death of the animal.
