Caries in the elderly has been associated with dependence, oral-health status and -care practices. This cross-sectional study aimed to investigate the association between root/coronal caries and individual factors among institutionalised elderly people in Bogotá, Colombia, using the International Caries Detection and Assessment System severity and activity criteria (ICDAS).
A total of 226 institutionalised elderly were clinically examined for root and coronal caries in 40 institutions. Caries risk was assessed with Cariogram, and demographics, oral health knowledge and practices, oral health-related quality of life and denture-use habits using a questionnaire.
Participants (mean age: 80.1 ± 9.3 years; 63.7% female) presented a mean number of 10.8 ± 7.3 teeth and 19.4 ± 18.8 exposed root surfaces. Prevalence of Coronal-ICDAS caries experience (C-ICDAS DF) was of 100% and of 54.4% for C-ICDAS D; mean number of C-ICDAS DFS was 16.76 ± 27.36, with 50.9% of subjects having ≥ one active C-ICDAS DS. Prevalence of Root Caries Index was of 49.1% and of R-ICDAS DF of 46%; mean number of R-ICDAS DFS was 2.03 ± 2.78, with 40.3% of subjects having ≥ one active R-ICDAS DS. Most individuals had a systemic condition (94.2%) and required oral-hygiene assistance (58%). Logistic regression analyses showed significant associations (p < 0.05): for coronal active caries when having over six teeth (OR: 2.7), and for root caries, when having coronal caries (OR: 2.41), being a man (OR: 1.95), and having over 14 teeth (OR: 0.30). Those presenting with > eight exposed root surfaces were 4.04 more likely to have root caries and 2.4 times more likely to have active root caries.
In the institutionalised elderly population in Bogotá significant associations were found, both for the presence as for the activity status of root and coronal caries, with individual clinical factors including coronal caries, exposed root surfaces and number of teeth.
老年人的龋齿与依赖、口腔健康状况和口腔保健措施有关。本横断面研究旨在使用国际龋齿检测和评估系统（ICDAS）的严重程度和活动标准，调查哥伦比亚波哥大的机构老年人中根/冠龋与个体因素之间的关系。
对 40 家机构的 226 名机构老年人进行根和冠龋的临床检查。使用 Cariogram 评估龋齿风险，使用问卷评估人口统计学、口腔健康知识和习惯、口腔健康相关生活质量和义齿使用习惯。
参与者（平均年龄：80.1±9.3 岁；63.7%女性）的平均牙齿数为 10.8±7.3 颗，暴露的牙根面数为 19.4±18.8 颗。冠部 ICDAS 龋齿经历（C-ICDAS DF）的患病率为 100%，C-ICDAS D 的患病率为 54.4%；C-ICDAS DFS 的平均数量为 16.76±27.36，50.9%的受试者有≥1 个活跃的 C-ICDAS DS。根龋指数的患病率为 49.1%，R-ICDAS DF 的患病率为 46%；R-ICDAS DFS 的平均数量为 2.03±2.78，40.3%的受试者有≥1 个活跃的 R-ICDAS DS。大多数人患有系统性疾病（94.2%），需要口腔卫生协助（58%）。逻辑回归分析显示具有显著相关性（p<0.05）：当有超过 6 颗牙齿时，与冠部活动性龋齿相关（OR：2.7）；当有根龋时，与冠部龋齿相关（OR：2.41）；与男性（OR：1.95）和有超过 14 颗牙齿（OR：0.30）相关。那些有超过 8 个暴露的牙根面的人，患根龋的可能性增加了 4.04 倍，患活动性根龋的可能性增加了 2.4 倍。
在波哥大的机构老年人中，无论是根龋和冠龋的存在还是活动状态，都发现了与个体临床因素（包括冠部龋齿、暴露的牙根面和牙齿数量）显著相关。
