浙江省平湖市12、14岁学生龋病流行病学调查

目的了解平湖市城乡12、14岁年龄组学生恒牙龋齿状况及相关发病因素,为龋病预防提供科学依据。方法采取随机抽样调查方法,按照WHO口腔调查基本方法中的龋病诊断标准对平湖市城乡12岁1030名和14岁1012名学生进行口腔龋病及相关因素调查。结果 1030名12岁学生患龋率为56.02%,龋均为1.30,显著性龋均指数3.06,充填率9.71%,残冠残根率10.98%,有80.10%儿童偏好甜食和饮料或二者同时兼食。14岁1012名学生患龋率为60.87%,龋均为1.71,显著性龋均指数3.98,充填率19.96%,残冠残根率17.89%,89.43%学生偏好甜食和饮料或二者同时兼食。两组女性患龋率均高于男性,差异有统计学（P〈0.05）;偏好甜食或甜食和饮料同时食用者患龋率高,与无不良饮食习惯者差异有统计学差异（P〈0.05）;两年龄组间患龋率差异无统计学意义（P〉0.05）。结论平湖市12、14岁学生患龋率高,残冠残根率较高,治疗率低,偏好甜食和饮料者多。

Epidemiological investigation of dental caries on 12, 14 years old students in Pinghu City of Zhejiang Province

Objective To investigate the permanent dental caries status and related risk factors on 12, 14 years old students in Pinghu City, to provide the scientific evidence of caries disease prevention. Methods 1030 cases of 12 years old students and 1012 cases of 14 years old students were selected to investigate the permanent dental caries status and related risk factors according to random sampling method and WHO oral survey basic method in Pinghu City. Results Dental caries rate of 12 years old students among 1030 cases was 56.02%, average caries was 1.30, significant caries index was 3.06, dental caries filling ratio was 9.71%, the residual crown and residual root rate was 10.98%,80.10% children were enjoyed with sweet food and drinks or both of them. Dental caries rate of 14 years old students among 1012 cases was 60.87%, average caries was 1.71, significant caries index was 3.98, dental caries filling ratio was 19.96%, the residual crown and residual root rate was 17.89%, 89.43% children were enjoyed with sweet food and drinks or both of them. The dental caries rate in female was higher than that in male in both groups, the differences were statistically significant（P〈0.05）. The dental caries rate in children with sweet food and drinks or both of them was higher than that without poor dietary habit, the differences were statistically significant（P〈0.05）. The dental caries rate in the two age groups was not statistically significant（P〉0.05）. Conclusion 12, 14 years old students in Pinghu City have high dental caries rate, high residual crown and residual root rate, low treatment rate, and has high preference rate of sweet food and drinks.
