COMBINED SELF-APPLIED FLUORIDES AND SEALANTS FOR CARIES PREVENTION

1972年10月，一项自我管理的牙齿健康计划 开始于弗吉尼亚州的纳尔逊县，一个缺乏氟化物的社区。 该县学校的孩子们在老师的监督下咀嚼 每天服用1毫克氟片，每周用0.2%的氟化钠冲洗 解决方案。一种含氟牙膏供随意使用，网址为 回家。对2138名儿童进行了基线DMFS检查 在该县小学(1-6年级)、初中(7年级和8年级)、 和高中(9-12年级)。后续DMFS 检查每隔两到三年进行一次，直到 1983年，该计划实现了充分的有效性。 1983年秋天，密封剂计划被添加到正在进行的 氟化物计划。6岁、7岁、12岁和13岁的儿童有资格 使用坑缝密封剂。最初的筛选是为了 识别要密封的牙面是在12月制作的 1983年。携带1983年9月的牙科数据(DMF) 考试将作为那些符合以下条件的孩子的基线 参与研究的密封剂阶段。在随后的几年里， 已经招收了新的6岁和12岁的儿童。治疗 已经持续了四年。进行中期牙科检查 在研究第三年开始时(1985年9月) 期末考试将于1987年9月进行。

In October 1972, a self-administered dental health program was started in Nelson County, Va., a fluoride-deficient community. Children in the County's schools, under teacher supervision, chew and ingest daily a 1 mg F tablet and rinse weekly with a 0.2% NaF solution. A fluoride dentifrice is provided for ad libitum use at home. Baseline DMFS examinations were made of 2138 children in the County's elementary (grades 1-6), junior (grades 7 and 8), and senior (grades 9-12) high schools. Follow-up DMFS examinations were conducted at two-to-three year intervals until 1983 when the full effectiveness of the program was achieved. 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. Carries data (DMFS) from the September 1983 dental examination will serve as a baseline for those children who participate in the sealant phase of the study. In succeeding years, new groups of 6 and 12 year olds have been enrolled. Treatments have continued for four years. Interim dental examinations took place at the start of the third year of the study (September 1985) and the final examinations will be made in September 1987.
