Geriatric dentistry researchers are building a basic knowledge basic pertaining to the oral health status of older adults. Important findings on the prevalence of disease that run counter to “conventional wisdom” surrounding the oral health of older adults are that edentulism is decreasing, that both coronal and root caries are prevalent, that serious periodontal disease is not as prevalent as thought, that chronological age is not strongly associated with disease in older adults, and that oral lesions, especially those related to dentures, are prevalent. An important finding has been that the majority of disease seems to occur in a minority of the population. While the prevalence of oral diseases have been shown to be associated with water fluoridation, systemic diseases, use of medications, social and behavioral factors, and a variety of other oral conditions, there is only preliminary information on the incidence of disease and actual risk factors. The data available on the incidence of disease come from a study of community‐dwelling older adults in Iowa, and these data generally confirm the prevalence results. Coronal and root caries are active in this older population with caries being the best predictor of tooth loss. Furthermore, most disease occurs in a high risk group. Multivariate models predicting people at highest risk for root and coronal caries implicate stress and anxiety, use of tobacco, and recent onset of illness as risk factors. In addition, preliminary results indicate that some dental conditions may be predictive of general health s
