The oral health and attitudes to dental treatment of a dentate elderly population in Mosgiel, Dunedin.

As part of the Mosgiel Community Study, a longitudinal investigation of the health of the elderly, a dental survey was used to determine the oral health status and treatment needs, both objective and subjective, of a group of dentate older adults. Sixteen percent of the 817 subjects were dentate. Of these, 95 were available for the dental survey, and they were questioned and examined at their homes. The mean age was 77 years, and 55 percent of subjects were male; disproportionately more older males than females had retained some of their natural teeth. Seventy-two percent regularly sought dental treatment, and 39 percent felt they were in need of treatment. Few real barriers to treatment were identified, although a major obstacle preventing many from seeking treatment was their lack of perceived need. However, even the realisation that they required treatment was not sufficient cause for many to seek treatment. All subjects required some form of dental treatment. Eighty-five of the 95 subjects required at least one restoration, and 16 percent advanced restorative treatment. The frequencies of coronal and root surface caries were similar. Oral mucosal pathology was also common. Sixty-five percent of denture wearers required prosthetic treatment. Most subjects needed simple periodontal treatment, but 11 percent required advanced therapy. The main oral health problems of this group related to the simple management of plaque-related disease, and the wearing of dentures. However, 24 percent of people required complex restorative and periodontal treatment, or both.
