[Elevated tooth abrasion in people of older age groups]

Specific features of tooth abrasion were studied in 105 patients aged 46-65 with the use of special questionnaires and Smith and Knight's abrasion index. Mandibular teeth were characterized by a higher abrasion level, the first and second right molars wearing down the first. Of the maxillary teeth the frontal ones were worse worn down. Potable water enrichment with fluorine (up to 2 mg/l) did not reduce the level of teeth abrasion.
