At present, it has been regarded that oral disease was one of the most prevalent problems for people's general health around the world. Oral disease burden study focuses on the pressure and effect of oral diseases to the whole social economy and people's health. Oral disease burden, as a public health problem, needs to be attached importance in China and foreign countries. By means of retrieving the literature, this review article summarizes the progress of domestic and oversea studies on oral disease burden, analyses the epidemiological burden through the indicators such as the prevalence rate, decayed missing and filled teeth, disability adjusted life years, disability weights, and illustrates the economic burden of oral diseases by using part of the data. Results shows that the oral disease burden is obvious in most countries and regions both in China and foreign countries. The study of oral disease burden in China has not been well developed. Giving priority to dental caries, periodontal disease and tooth loss, the prevalence of oral diseases in China is high. The rate of seeking dental treatments is low and the proportion of self-supporting treatments is high. In general, the epidemiological and economic burden of oral diseases is heavier in China than that in the rest of the world.
口腔疾病目前已成为世界上大部分人群的健康问题之一。口腔疾病负担研究是对口腔疾病造成的社会经济和人群健康压力与影响的研究，是国内外各个国家地区需要重视的公共卫生问题。本文通过文献回顾的方法，总结了口腔疾病负担在国内外的研究进展，通过患病率、龋均、伤残调整寿命年、伤残权重等指标对口腔疾病的流行病学负担进行比较，并通过一些数据说明口腔疾病的经济负担现状。结果表明口腔疾病在国内外大部分国家、地区均为明显的疾病负担，而我国对口腔疾病负担的研究尚不成熟，以龋病、牙周病、失牙为主的口腔疾病在我国患病率高，社会大众的就诊率低，且医疗费用自付比例高，相对而言，我国口腔疾病的流行病学和经济负担较重。.
