Analysis of periodontal health status and its related factors in the elderly in Haikou city / 中华老年医学杂志

ABSTRACT

Objectives To investigate the prevalence rate of periodontal diseases in the elderly aged 65～74 years in Haikou,and to provide basic data for the diseases prevention.Methods A total of 875 residents(aged 65-74 years)were selected using stratified random sampling in four areas of Haikou,and oral health checks were conducted.Results The prevalence rate of periodontal disorders,such as gingival bleeding,dental calculus,periodontal pockets was 57.8％,83.5％ and 24.0 ％,respectively.In average,9.2 (gingival bleeding),16.6 (dental calculus) and 1.7 (periodontal pockets)teeth were detected in each person.Detection rate of loss of periodontal attachment(LOA)of ≥4 mm(at least 1 teeth)was 55.7％,while the percentages of LOA ≥ 6 mm(at least 1 teeth)declined to 17.6％.Binary Logistic regression analysis showed that dentures were a risk factor for bleeding gums.With aging,risk of the formation of dental calculus became lower.The risk of the formation of dental calculus was 1.98 times higher for the elderly without denture than for the elderly with denture.The risk of the formation of periodontal pockets was higher in men than in women.The risk of the formation of periodontal pockets became higher in the elderly from poor families.The risk of the LOA≥ 4 mm was 1.40 times higher for rural original-addressed elderly than for urban originaladdressed elderly,and smoking and drinking were risk factors for LOA≥4 mm.Conclusions The periodontal health status of the elderly in Haikou is not optimistic.Factors affecting periodontal health are multifaceted.Therefore,appropriate measures should be taken to improve the oral health status of older persons.
