摘要
目的调查滨海新区适龄儿童氟斑牙与窝沟龋的患病情况,探讨氟斑牙与窝沟龋的关系,为氟斑牙与窝沟龋的防治提出指导意见.方法参考《WHO 口腔健康调查基本方法》（第四版）,并参照第三次全国口腔流行病学调查方法,采用横断面调查研究方法对3 778 名7～9 岁教育水平相近的儿童进行氟斑牙与窝沟龋情况进行调查.结果样本中氟牙症发生率〈10%,社区氟牙症指数（CFI）为0.075.男学生第-恒磨牙的患龋率和龋均分别是15.57%、0.46,而女学生第-恒磨牙的患龋率和龋均分别是17.41%、0.58.男女间第一恒磨牙患龋率（χ^2=2.345,P〉0.05）和龋均无差异.不同年级组患龋率（χ^2=172.576,P〈0.05）和龋均有差异,两者均随年级的增长而上升.结论天津市经过多年改水降氟工程之后,在本地区儿童氟斑牙检出率及氟斑牙指数已经呈现下降趋势;患龋率可能与第一恒磨牙的萌出率存在相关性.
Objective To investigate the incidence of dental fluorosis and pit caries in school-age children from binhai newarea of Tianjin, and to discuss the relationship between dental fluorosis and pit caries, providing the guidance for the preventionand treatment of them. Methods Referring to WHO’s“Oral Health Surveys Basic Methods”（Fourth Edition） and protocols ofthe third national oral epidemiology investigation, 3 778 children aged 7 to 9 year-old with similar levels of education wereinvestigated for their dental fluorosis and fissure caries using the cross sectional survey method. Results The data showed thatthe incidence of dental fluorosis was less than 10% in the samples, and the community fluorosis index （CFI） was 0.075. The cariesprevalence rate and mean decayed missing filled tooth （DMFT） of first permanent molars were 15.57% and 0.46 in male students,and those were 17.41% and 0.58 in female students. There were no significant differences in the caries prevalence rate and DMFTof first molar between male and female children （χ^2 =2.345, P 〉 0.05）. There were statistically significant differences in the cariesrate and DMFT between different age groups （χ^2=172.576, P 〈 0.05）, and both increased with age. Conclusion After years ofdefluoridation project in Tianjin, the detection rate and index of dental fluorosis in children have showed a downward trend. Thecaries prevalence rate may be related to the eruption rate of the first permanent molar.
