Radiographic findings in a group of elderly patients at a Canadian dental school.

The panoramic and intraoral radiographs of 154 elderly dental patients aged 65 years and older were assessed at the College of Dentistry, University of Saskatchewan, Saskatoon. Thirty-seven per cent of the patients were completely edentulous, and 61% were partially edentulous. In the dentate group, 87% had evidence of at least one carious tooth, and all had radiographic evidence of alveolar bone loss. The incidence of periapical inflammatory lesions and root remnants was relatively high.
