  • Title: Prevalence of and factors associated with root decay in older adults in Canada.
    Author: Locker D, Slade GD, Leake JL.
    Journal: J Dent Res; 1989 May; 68(5):768-72. PubMed ID: 2715468.
    Abstract:
    We collected data on the oral health status and treatment needs of a random sample of persons aged 50 years and over. Data on root decay were obtained from the 183 subjects who were dentate. All remaining teeth were examined for root decay and restorations, whether root surfaces were affected by recession or not. Analysis was undertaken by case and root surface, with separate analyses of decayed (DS), and decayed and filled (DFS) root surfaces. One or more root surfaces with untreated decay were found in 37.2% of subjects, while one or more decayed or filled root surfaces were found in 56.8%. The mean number of decayed surfaces was 1.3 per person, and the mean number of decayed and filled root surfaces was 2.6. Multiple and logistic regression analyses showed that oral health variables were more important predictors of the presence and severity of root decay than demographic, general health, or dental care factors.
