Abstract：Objective To study the status and the risk factors of dental caries in high-risk elderly people in Liaoning,in order to provide basic research data for establishing Logistic model of high-risk elderly people with dental caries.Methods From May to December 2015,1144 elderly people aged 65 ～ 74 were randomly selected to take an oral examination,and a questionnaire survey was also performed.Chi square tests and multifactor Logistic regression analysis were used to analyze the results by SPSS 13.0 software.Results The dental caries prevalence was 68.53％.Elderly people living in urban areas had no significant difference with those living in rural areas on caries prevalence (73.12％ vs.63.92％,P ＞ 0.05).The same status existed in gender difference (67.78％ vs.69.27％,P ＞ 0.05).A multiple Logistic regression analysis showed that rural residence (OR =0.676,95％ CI:0.503-0.908),seldom smoking (OR =0.681,95％ CI:0.502-0.923),and seldom drinking (OR =0.628,95％ CI:0.446-0.885) were negatively associated with dental caries in elderly people.The experience of toothache in the recent one year (OR =1.550,95％ CI:1.164-2.063) was the risk factor of the dental caries.Conclusion The prevalence of dental caries is high in elderly people in Liaoning,with experience of toothache in the past 1 year being positive determints and rural residence,seldom smoking,and seldom drinking being negative determints.
