The dental examinations were conducted by one trained dentist in the elderly homes using a portable clinic light, mouth mirror, and dental explorer. Two\u2010level logistic regression analyses, one using the presence of decay and the other using decay\/filling in the root surface as the dependent variable, were conducted to study the relationship between root caries and a number of selected subject\u2010level and site\u2010level factors.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 306 elders with a mean age of 78.8\u00a0years were examined.
