    Abstract:
    One in ten persons over the age of 65 and as many as half the population aged 85 and over have Alzheimer's disease. Review of the literature reveals substantial decrements in oral health in persons with dementia as measured by denture hygiene, coronal decayed, missing and filled teeth, filled teeth (cervical), percentage of the population with caries, Oral Hygiene Index-simplified, and of sites with plaque, gingival bleeding and calculus. A study of caries incidence is described in 23 male veterans with moderate and advanced dementia of the Alzheimer's type, using a comparison group of male veterans from the Department of Veterans Affairs Dental Longitudinal Study, matching 2:1 for age, number of teeth and education. Baseline findings indicate significant differences in the numbers of coronal surfaces with decay, root decayed and/or filled teeth and root decayed and/or filled surfaces. Mean annual increments of coronal caries in the dementia group were 2.29 +/- 4.29 per 100 surfaces at risk, over twice that in the comparison group (0.88 +/- 1.14). For root caries, mean annual increments in the dementia group were 2.38 +/- 5.57 per 100 available surfaces, versus 0.31 +/- 0.69 in the comparison group. Despite these large mean differences, the marked variability in these small samples statistical significance in caries increments between the two groups. The article concludes by suggesting some potential modifications to clinical trials of caries preventive agents and some overall research issues in populations with dementia.
