[Experimental reproduction of the mechanical process of dental attrition by abrasion: paleoecological implications to fossil man].
By microscopic examination we differentiated rays appearing on dental surfaces according to the geometry of abrasive grains which produced them. Since the aspect of particules originally relied on paleoecological conditions, this new research helps us to complete our knowledge of the bolus and of fossil environment.
