The association of medications with sedative properties with oral health behaviour in community-dwelling older people

ObjectivesThe objective of this study was to determine whether drugs with sedative properties are related to oral health behavioursuch as frequency of toothbrushing, using toothpaste and dental visitsand oral hygiene, measured by the number of teeth with dental plaque, among community-dwelling older people. MethodsThe study population consisted of 159 community-dwelling, dentate, non-smoking, older people from the Oral Health GeMS study (Geriatric Multidisciplinary Strategy for the Good Care of Older People study). The data were collected by interviews and clinical examinations during 2004-2005. Sedative properties of drugs were assessed using the sedative load (SL) model. Logistic and Poisson regression models were used to estimate odds ratios/relative risks (OR/RR) and 95% confidence intervals (CI). ResultsAfter adjusting for confounding factors, SL associated with infrequent toothbrushing (OR 1.72, CI: 0.61-4.89), toothpaste use less than twice a day (OR 3.34, CI: 1.39-8.12), non-regular dental visits (OR 2.28 CI: 0.91-5.30) and the number of teeth with dental plaque (RR 1.20 CI: 1.04-1.39) compared to participants without a SL. ConclusionsThe results of this study suggest that use of drugs with sedative properties indicates poor oral health behaviour among older people.
