Purpose: Increased wear of teeth may constitute a major problem in the future for the elderly. The aim of the present study was to investigate tooth wear in a sample of elderly Greeks and explore the presence and extent of severe occlusal/incisal wear in relation to the parameters of age, gender and remaining teeth. Materials and Methods: A convenience sample of 70 dentate elderly (60–92 years old) was examined. Tooth wear was assessed using a modification of the tooth wear index. The presence of severe occlusal/incisal wear was explored using the multiple correspondence analysis (MCA) and x2 tests and the extent (% of surfaces) with analysis of variance (ANOVA). Results: Increased prevalence of severe wear was observed in the occlusal/incisal and, to a lesser extent, in the cervical surfaces of the examined teeth. Seventy per cent (70%) of the participants had at least one severely worn tooth surface. Advanced age seemed to be associated with severe occlusal/incisal wear (>70 years: 79.4%; 60–70 years: 52.8%; x2 test, p = 0.024). The mean (± SD) percentage of severely worn teeth and surfaces was 34.2 ± 32.6% and 9.6 ± 9.6%, respectively. ANOVA showed that males and those with less than 20 remaining teeth exhibited more severely worn occlusal/incisal surfaces (p = 0.031 and p = 0.000, respectively). Conclusions: The presence and the extent of severe wear in the sample of the examined elderly is high compared to elderly populations in other countries. Severe wear was more prevalent with advanced age and more extensive in the occlusal/incisal surfaces in males and those having less than 20 remaining teeth.
