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 县里的学校，在老师的监督下，每天咀嚼和摄入1 每周用0.2%的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、初中的2138名儿童进行了检查 高中和高中。进行了DMFS的后续检查 每隔两到三年。期末考试于1983年进行。 何时可以评估氟化物计划的全部效果。 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 使用坑缝密封剂。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。在成功中 几年后，新的6岁和12岁的儿童被招募进来。治疗仍在继续 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 1987年9月。数据分析已接近完成，并准备 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.
