Prevalence and intraoral distribution of coronal and root caries in middle-aged and older adults.

This work describes the prevalence and intraoral distribution of coronal and root caries in 326 predominantly white, educated, middle-aged and older adults. Study participants were recruited from Tufts Geriatric Outreach Program, Nutritional Status Study (NSS), and the Forsyth Root Caries Study. Eighty-five percent of participants reported visiting their dentist in the last year. The median number of teeth was 21 in the 65+ age-group, and 40% of participants had coronal caries and 33% had root carious lesions. The mean coronal and root caries (DFS) was higher and the proportion of decayed surfaces to all decayed and filled surfaces (%D/DFS) was lower than in other comparable studies. A comparative analysis of intraoral distribution of coronal and root caries and their relation with age is discussed.
