COMBINED SELF-APPLIED FLUORIDES AND SEALANTS FOR CARIES PREVENTION

纳尔逊县启动了一项自我管理的牙齿健康计划， 弗吉尼亚州，一个缺氟的社区儿童 县的学校，在教师的监督下，咀嚼和摄入每天a1 mg F片剂，每周用0.2%NaF溶液冲洗。氟化物 在家中随意使用。基线DMFS 对该县小学、初中和高中的2,138名儿童进行了检查， 高中和高中。进行了随访DMFS检查 每隔两到三年1983年举行了期末考试 当氟化物项目的全部效果可以被评估的时候。 在1983年秋天，一个密封剂计划被添加到正在进行的氟化物 程序. 6岁、7岁、12岁和13岁的儿童有资格获得 使用了窝沟封闭剂。初步筛选，以确定那些 1983年12月制造了待密封的齿面。龋齿数据（DMFS） 从1983年9月的牙科检查作为基线， 参与研究的密封剂阶段的儿童。在继 2002年，6岁和12奥尔兹的新群体被招募。继续治疗 四年了临时牙科检查在开始时进行， 研究的第三年（1985年9月）和期末考试进行了 1987年9月。数据分析已接近完成， 最后报告已经开始。

A self-administered dental health program was initiated in Nelson County, Va., a fluoride-deficient community in October 1972. Children in the County's schools, under teacher supervision, chewed and ingested daily a 1 mg F tablet and rinsed weekly with a 0.2% NaF solution. A fluoride dentifrice was provided for ad libitum use at home. Baseline DMFS examinations were made of 2,138 children in the County's elementary, junior high, and senior high schools. Follow-up DMFS examinations were conducted at two-to-three year intervals. Final examinations were conducted in 1983 when the full effectiveness of the fluoride program could be assessed. In the fall of 1983, a sealant program was added to the ongoing fluoride program. Children who were 6, 7, 12, and 13 were eligible to have pit-and-fissure sealants applied. An initial screening to identify those tooth surfaces to be sealed was made in December 1983. Caries data (DMFS) from the September 1983 dental examination served as a baseline for those children who participated in the sealant phase of the study. In succeeding years, new groups of 6 and 12 year olds were enrolled. Treatments continued for four years. Interim dental examinations took place at the start of the third year of the study (September 1985) and final examinations were made in September 1987. Data analysis is nearly complete and preparation of final reports has been initiated.
