Oral health status and treatment needs of non-institutionalized persons aged 60+ in Adelaide, South Australia.

There has been a growing recognition of the need to obtain information about the oral health of older Australians. The aim of this report is to provide descriptive epidemiological information about the oral health and treatment needs of non-institutionalized older adults in Adelaide. Data from interviews with 178 persons aged 60+ were obtained from a pilot study. Clinical data were available for 106 persons who participated in oral examinations. Among the 52.9 per cent of dentate persons, the prevalence of root decay (27.1 per cent) was slightly higher than coronal decay (23.6 per cent). Some 28.1 per cent of dentate persons had a serious periodontal condition, defined as the presence of four or more teeth with at least 5 mm or more of periodontal attachment loss and periodontal pocketing of 4 mm or more at one or more of those teeth. The majority of persons (83.8 per cent) wore one or two dentures. Disorders associated with dentures were frequent, affecting 77.4 per cent of upper denture wearers and 72.5 per cent of lower denture wearers. Persons who were older, who had lower educational attainment or lower household incomes were disadvantaged in aspects of oral health status and dental caries. However, there were no consistent associations between chronic medical conditions and oral disorders. Despite the high prevalence of oral impairment, reflecting extensive disease activity in the past, high levels of untreated disease were relatively uncommon. Instead, a high prevalence of oral disorders created a substantial need for basic forms of dental treatment in this group.

Oral conditions and their social impact among HIV dental patients.

This study aimed to assess oral health status and the social impact of oral conditions among dental patients with HIV infection in comparison with general dental patients receiving public-funded care in Adelaide, South Australia. DMFT and CPITN indices were recorded by one dentist at a clinic for HIV dental patients. The data were compared with information from an existing survey of general dental patients. Social impact was assessed using the Oral Health Impact Profile questionnaire and responses from HIV dental patients were compared with responses from a telephone interview survey of Adelaide residents. HIV patients were aged 21 to 49 years (median = 34), 90.7 percent were male and 29.6 percent had stage 4 HIV infection. Oral candida was present among 32.0 percent, hairy leukoplakia among 24.1 percent, HIV gingivitis among 18.5 percent, and HIV periodontitis among 33.3 percent. The DMFT index and its components did not differ significantly between HIV and general dental patients, while CPITN scores were lower among HIV patients (p = 0.01). However social impact among HIV patients was frequent: 64.6 percent reported toothache, 43.7 percent avoided foods, and 16.7 percent avoided going out because of dental problems. HIV patients reported significantly greater levels of social impact than the Adelaide sample (p < 0.01). Patients to this clinic frequently presented with severe and disabling oral conditions which were not adequately captured using standard clinical indices.

Hepatitis C infection and associated oral health problems.

Hepatitis C infection is widespread throughout the community. This study aimed to assess the status of oral health of persons infected with hepatitis C. DMFT and CPITN indices were recorded at a clinic providing priority dental care for people with hepatitis C infection. The data were compared with information from an existing survey of general dental patients. Social impact was assessed using a modified Oral Health Impact Profile questionnaire. The DMFT index differed significantly between hepatitis C and general patients. The number of decayed and missing teeth was greater in those infected with hepatitis C for all patients aged between 25 and 50 years. Although there was no significant difference in CPITN categories for subjects evaluated, a marked trend for poor periodontal health was noted for those individuals with hepatitis C. Salivary flow was reduced in 50 per cent of hepatitis C infected subjects. Social impact was significantly affected with 71 per cent of hepatitis C subjects reporting painful aching in the mouth and 56 per cent having difficulty in relaxing. In conclusion, the results from the project strongly indicate an urgent need for priority delivery of dental care for people with hepatitis C infection.
