Very little is known about the oral health of, and access to, dental services among frail elders who live in the community and use an adult day health center (ADHC) for respite care. This pilot study evaluated the perceived oral health quality of life (OHQOL) of elders who used a mobile dental program in urban, suburban, and rural ADHC settings. Pre- and post-treatment interviews were conducted to evaluate OHQOL using the Geriatric Oral Health Assessment Index (GOHAI). ADHC records were used to obtain demographic, medicai history and medication data. Following initial dental examinations and consent, dental treatment was provided at each ADHC. Of the 138 elders screened at three ADHCs, pre- and post-treatment data were obtained on 76 subjects following their treatment (mean four months later). The groups members were mostly female (64.5%) and Caucasian (71.6%). Their mean age was 76.8 (+/- 9.8), with an average of 12.4 teeth (34.2% edentulous); 67.7% were on Medicaid. On average they had 5.5 chronic diseases, hypertension being the most common (67.1%); 44.8% had a neurological disorder or dementia. GOHAI scores were generally high both pre- and post-treatment, reflecting high physical and psychosocial OHQOL and low leveis of worry. GOHAI scores were correlated with chronic diseases; the more chronic diseases an individual had, the lower his or her total score pre- and post-treatment (r=-.24, r=-.26 respectively, p<.04). The more dental treatment needs an elder had, the lower his or her GOHAI (r=-.23, p<.05). Elders with more teeth reported higher GOHAI pre- and post-treatment (r=.36, r=.37 respectively, p<.002). Paired t-tests comparing pre- and post-treatment GOHAI scores revealed significant improvements in overall GOHAI (p<.001), and on two dimensions: physical (p<.005) and psychosocial (p<.002). The findings support the importance of providing on-site access to dental services in order to maintain the general OHQOL of frail elders, more specifically in the areas of physical and psychosocial well-being.
