| Abstract | MATERIALS AND METHODS: 86 adult skulls, dating from the 3rd to 18th century, which were found in the area which today is known as Slovenia. The degree of occlusal wear was measured by using the scale devised by Molnar. Age and sex were known in almost all cases. Dental rulers were used for 30 different measurements. Four angular measurements were performed through photographic basis. The slope of abraded occlusal facets from canine and first molar teeth were classified. The scale devised by Richards was used for the assessment of the severity of degenerative changes of the temporomandibular joints. The condyles were classified according to the scales devised by Mongini and by Oeberg. Statistical analysis of the relationships between tooth wear and all other variables using the linear regression method and Pearson correlation test were performed. RESULTS: tooth wear is a function of age (p < 0.001). Males have on average more abraded teeth than females of the same age group (p = 0.012). Tooth wear is conversely related to the number of remaining teeth (r = -0.336). Slopes of the wear facets on the first molar teeth (p = 0.058 for the left side and p = 0.090 for the right side) and a slope of the condyle path (p = 0.096 for the left side and p = 0.008 for the right side) were related to the average tooth wear index. The depth of the temporal fossa (p = 0.064 for the right fossae and p = 0.040 for the left ones) and the condylar dimensions become bigger with the higher tooth wear. The loss of the tooth crowns results in the loss of the facial vertical dimension which influences on the articular surfaces of the joints (p = 0.020 for the right fossae and p = 0.024 for the left ones). Gonial angle (r = -0.207 for the right angles and r = -0.279 for the left ones) and bigonial width (p = 0.073) are statistically significantly related to the extent of the tooth wear.
