Cervical tooth abrasion was assessed for 520 elderly people who were representative of the non-institutionalized dentate elderly in 2 rural Iowa counties. In this dentate population, 56% of the people had some cervical abrasion, with 30% having abrasion more than 1 mm in depth. Abrasion was found on 16% of all teeth, 5% being deeper than 1 mm. The prevalence of cervical abrasion varied by tooth type, with maxillary premolars most frequently affected. Regression analysis identified 5 independent variables that were related to the number of teeth with cervical abrasion (R2 = .335). These factors were consistent with a hypothesis of vigorous toothbrushing as the major etiologic factor.
