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，1972年10月，一个氟化物缺乏的社区。世界上的孩子们 在老师的监督下，县里的学校每天都在咀嚼和摄取 1 mg氟片，每周用0.2%氟化钠溶液冲洗一次。一种氟化物 在家中提供了牙膏供随意使用。基准DMF 对该县小学的2138名儿童进行了检查， 初中和高中。后续的DMFS检查是 每隔两到三年进行一次。期末考试是 在1983年进行的氟化物计划全面生效时 可能会被评估。 1983年秋天，一项密封剂计划被添加到正在进行的氟化物中 程序。6岁、7岁、12岁和13岁的儿童有资格获得PIT- 并应用了裂隙封闭剂。初步筛查以确定 待密封的齿面制作于1983年12月。龋齿数据(DMF) 从1983年9月的牙科检查开始， 参与研究密封剂阶段的儿童。在……里面 在接下来的几年里，新的6岁和12岁的儿童被招募进来。 治疗持续了四年。进行中期牙科检查 在研究的第三年开始时(1985年9月)和 期末考试于1987年9月进行。数据分析完成 目前正在编写最后报告。

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 complete and preparation of a final report is underway.
