To analyze the dental caries prevalence and severity in 3-year-old children from Jing'an district of Shanghai, and provide epidemiologic evidence for monitoring dental decay for establishing policies of preventive and treatment.
The surveillance was conducted using random cluster sampling method, 959 3-year-old children from Jing'an district was investigated in regard to dental caries. SPSS 15.0 software package was used for statistical analysis.
The caries prevalence rate of deciduous tooth in 3-year-old children was 28.05.%. The incidence in males was significantly higher than that in females (P<0.05). The index of decayed, missing or filled-teeth（dmft）was 0.87, there was no significant difference between different genders.The caries filling ratio was 5.44%, with no significant difference was noted between different genders. Dental caries was mostly seen in the primary mandibular second molars，and least seen in the primary mandibular lateral incisor.
Caries prevalence is high in 3-years-old children, and the majority is left untreated. Oral health care should be strengthened in this population.
分析上海市静安区3岁儿童龋病的患病率及严重程度，为龋病监测及制定防治策略提供流行病学依据。
采用随机整群抽样方法进行监测，对静安区959名3岁儿童进行龋病调查。采用SPSS 15.0软件包进行统计分析。
3岁儿童乳牙龋病患病率为28.05%。男性发病率显著高于女性（P<0.05）。龋失补牙指数（dmft）为0.87，不同性别间差异无统计学意义。龋病充填率为5.44%，不同性别间差异无统计学意义。龋病主要发生在乳牙下颌第二磨牙，最少见于乳牙下颌侧切牙。
3岁儿童龋病患病率高，且多数未治疗。应加强该人群的口腔保健。
