Dimensions and occlusal patterns in molars of Hystrix brachyura Linnaeus, 1758 (Mammalia, Rodentia) in a system of wear categories

Molars of 35 skulls of Hystrix brachyura brachyura Linnaeus, 1758 have been studied. Problems with the currently used dental nomenclature are discussed. A positional, numerical system for the indication of occlusal elements, and a system of wear classes for all the different occlusal patterns are presented. Dimensions of the teeth in relation to wear are given, the variation in the occlusal patterns is described and their changes with progressive wear are discussed.
