2005年广东省成年人恒牙冠龋病抽样调查报告

Crown Caries in An Adult Guangdong Cohort:A Sampled Investigation

目的了解广东省35-44岁、65-74岁人群恒牙龋病状况,为广东省口腔卫生保健工作提供信息支持。方法采用多阶段分层等容量随机抽样的方法,抽取广东省35-44岁、65-74岁城乡常住人口各720人,男女各半。按照《第三次全国口腔健康流行病学调查方案》中临床检查牙列状况的检查方法和标准,使用CPI探针检查全口恒牙牙冠龋病情况。数据采用SAS8.1软件统计,计算出患龋率、龋均。结果35-44岁组恒牙患龋率为63.89%、龋均为1.99;患龋率和龋均均为女性高于男性,农村高于城市。65-74岁组患龋率为74.17%、龋均为3.37;患龋率和龋均均为农村高于城市。结论广东省成年人群龋病患病率较高,人群大部分龋齿未得到治疗。

Objective To investigate the current status of crown caries on permanent teeth in adult population at the age of 35 - 44 and 65 - 74 years in Guangdong province, thus to provide scientific basis for the establishment of oral health care policies in Guangdong. Methods An equal-sized stratified multi-stage randomly sampling design was applied to obtain two provincially representative sample groups consisted of 720 Guangdong residents each, aged at either 35- 44 or 65 - 74 years old respectively, with a gender ratio of half to half. The caries on the crowns of permanent teeth were assessed according to The Guideline for the 3rd National Oral Health Survey, thereafter the caries rate and decayed, missing and filled tooth （DMFT） of permanent teeth were calculated. The data obtained were analyzed using SAS package. Results In the population aged 35 - 44, the caries rate was 63.89%, with a DMFT of 1.99, while the corresponding figures in age group of 65 - 74 were 74.17 % and 3.37, respectively. In both age groups, relative high levels of caries rate and DMFT was recorded in countryside when compared to the urban opponents. However, gender difference was only noticed in age group of 35 - 44 and the female had a high DMFT score and caries rate level. Condusion The data suggested that there is a high level of crown caries in Guangdong cohort, with most of the involved teeth not treated.
