Dental wear in dolphins (Cetacea: Delphinidae) from southern Brazil
Archives of Oral Biology, 2013 (1) Dental wear is a common phenomenon in mammals. Its occurrence is influenced by tooth anatomy, animal physiology, biomechanics and behaviour. So far, investigations of dental wear in cetaceans have been scanty and superficial. We compare the frequencies of occurrence, location and intensity of dental wear in some species of dolphins from southern ...
