摘要
Abstract
Objective To explore the prevalence and risk factors of root caries among the elderly in Guangzhou city in order to provide reference information for the prevention of root caries in the elderly. Methods Cross-sectional study was carried out in 513 people aged 65-74 years who were studying at the University for the elderly. Oral examination was taken by a trained and standardized dentist, the root caries index and other clinical variables were recorded. Question-naires were administered to collect socioeconomic, sociodemographic and oral hygiene data. Statistical analyses were per-formed using parametric tests. Results The prevalence of root caries was 65. 7%. The mean DFT was 2. 19 ± 1. 92. The prevalence and the mean DFT of men were 68. 8% and 2. 34 ± 2. 01, while 62. 7% and 1. 98 ± 1. 75 for women. The prevalence of root caries showed no significant difference between genders ( P=0. 147) , the mean DFT showed significant difference between genders ( P<0. 001) . Statistically differences of the caries prevalence were observed across food im-paction ( P=0. 016) , and were higher in dry mouth ( P<0. 001) . Those who were with dry mouth and/or with food im-paction had more root caries. Conclusion Strengthening the oral health education and forming a good oral health behav-ior are helpful to prevent the elderly root caries.关键词
