The purpose of this study was to analyze the life-course effects of education, occupation, and income at ages 70, 75, 80, and 85 years, respectively, on dental caries experience of 85-year-olds.
The present study includes follow-up data from a population-based study, which comprised a sample of 176 individuals aged 85 years. Data on social position were collected at ages 70, 75, 80, and 85 years by means of structured personal interviews. Clinical oral health examinations were conducted to obtain data on dental caries at age 85. Dental caries was recorded at tooth surface level and caries experience was expressed by the DMF Index: the decayed tooth surfaces (D component), missing tooth surfaces (M component), and filled tooth surfaces (F component).
The participants in the present study demonstrated a high level of dental caries experience; the prevalence rate for active dental caries (D-S) was 80 percent. Older adults with low education, low occupational status, and poor income tended to have more active dental caries compared to their counterparts. In contrast, individuals with high education (F-S = 35.5) and high occupational status (F-S = 36.0) had significantly more filled surfaces than persons with low education (F-S = 24.0) and low occupational status (F-S = 25.6). Individuals with high income at ages 75, 80, and 85 years had more filled surfaces (F-S = 31.9, 33.2, 34.1) compared to persons with low income (F-S = 25.5, 23.5, 22.8).
The study identified social inequalities across age among the very old individuals in relation to dental caries experience.
本研究旨在分别分析70岁、75岁、80岁和85岁时的教育程度、职业和收入对85岁老年人龋齿经历的生命历程影响。
本研究纳入了一项基于人群研究的随访数据，该研究样本包括176名85岁的个体。通过结构化个人访谈收集70岁、75岁、80岁和85岁时的社会地位数据。在85岁时进行临床口腔健康检查以获取龋齿数据。龋齿记录到牙面水平，龋齿经历用DMF指数表示：龋坏牙面（D部分）、缺失牙面（M部分）和充填牙面（F部分）。
本研究中的参与者表现出较高的龋齿经历水平；活动性龋齿（D-S）的患病率为80%。与教育程度高、职业地位高和收入高的老年人相比，教育程度低、职业地位低和收入低的老年人往往有更多的活动性龋齿。相比之下，高学历者（F-S = 35.5）和高职业地位者（F-S = 36.0）的充填牙面明显多于低学历者（F-S = 24.0）和低职业地位者（F-S = 25.6）。75岁、80岁和85岁时高收入者的充填牙面（F-S = 31.9、33.2、34.1）多于低收入者（F-S = 25.5、23.5、22.8）。
该研究发现高龄个体在龋齿经历方面存在年龄差异的社会不平等现象。
