Tooth and jaw (temporomandibular) joint (TMJ) diseases are common in certain wildlife species and may be important contributors to morbidity (sickness) and mortality (death). Our group has documented the dental and TMJ pathology of the elephant seal, southern sea otter, California sea lion, northern fur seal and the harbor seal. The aim of this study is to determine the nature and prevalence of dental and TMJ pathology in the walrus by examining skull specimens at the University of Alaska.
