Abstract:

As one of the most common chronic diseases of the oral cavity, caries gradually accumulate over the lifetime and affect approximately 80% of the world population. The epidemiological characteristics of the disease are specific in terms of regional distribution, temporal distribution and population distribution. Caries prevalence and mean decayed, missing and filled permanent teeth (mean DMFT) scores are the most commonly used indexes in oral epidemiology. Caries prevalence is used to describe the frequency of caries over a certain period of time. In addition, DMFT scores reflect the severity of caries in the population. The caries prevalence and the severity of caries are assessed as part of a dynamic process. In developing countries, caries prevalence is higher among urban populations than among rural populations. Currently, the epidemic characteristics of caries in urban and rural areas are changing, and the caries prevalence of urban residents is lower than that of rural residents. This article is a chronological review of the Oral Health Epidemiological Surveys of China from 1983 to 2015, the Preventive Dentistry study and other related studies. It is concluded that the epidemic characteristics of caries in urban and rural areas in China have changed from a higher caries prevalence in urban areas compared to that in rural areas to a lower caries prevalence in urban areas compared to that in rural areas. Several factors, such as the dynamic development of differences in dietary habits, economic levels and access to oral medical resources of urban and rural residents might have led to changes in caries prevalence in urban and rural areas. The caries prevalence of rural residents has increased greatly, which indicates that the caries prevention efforts of the relevant departments should be focused more on rural areas in the future.

摘要:

龋病作为一种最常见的慢性口腔疾病,其病变终生渐进累积,影响全球约80%的人群;其流行病学特征在地区分布、时间分布以及人群分布上具有特异性。患龋率和龋均是口腔流行病学中最常用的评价患龋状况的指标,其中患龋率用来描述某一时间段内人群中龋病的患病频率;龋均指人群中每人平均龋坏、因龋缺失和因龋补牙数,反映受检人群龋病的严重程度。人群患龋率及龋均是动态变化的指标。在发展中国家,一般城市居民的患龋率高于农村。本文对1983~2015期间全国口腔健康流行病学调查报告、《口腔预防医学》教材以及相关学者的研究报告按时间顺序进行回顾,总结出我国龋病城乡流行特征由最初的城市患龋水平高于农村过渡为目前的城市患龋水平低于农村。分析其差异原因,其中城乡居民饮食习惯、经济水平以及口腔医疗资源可及性等差异的动态发展导致城乡龋病患病水平的变化。农村居民患龋水平上升幅度较大,提示相关部门目前龋病预防工作的重点应更侧重于农村地区。
