This study assessed the treatment and posttreatment effects of a school-based, fluoride mouthrinse regimen.
Children in a nonfluoridated community in Japan participated in a daily rinse program using a 0.05 percent NaF solution in nursery and primary schools, and a weekly rinse with 0.2 percent NaF in junior high school. Students were examined at least annually for dental caries and dental treatment was provided in a public dental clinic through the ninth grade. Incipient carious lesions with no cavitation were not restored.
The percent of children in grades one through nine (6-14 years of age) with caries-free permanent teeth increased from 13.4 percent in 1974 to 73.0 percent in 1991, while the mean DMFT decreased by 86 percent during this period. For 12-year-olds, mean DMFT scores declined to about one tooth per child after 1982. For adults 20 years of age, there was a 64 percent difference in DMFS between the treatment group who started the rinse regimen at 4 years of age and continued for 11 years, and the controls who lived in different districts and did not participate in a fluoride rinse regimen.
Children who began rinsing at 4 or 5 years of age benefited the most from the program. The program was inexpensive, simple to implement and well accepted by families and teachers. The conservative treatment policy in the public clinic likely contributed to the benefits derived by participants.
本研究评估了一项基于学校的含氟漱口水方案的治疗及治疗后效果。
日本一个未进行氟化处理社区的儿童参与了一项日常漱口项目，幼儿园和小学阶段使用0.05%的氟化钠溶液，初中阶段每周使用0.2%的氟化钠溶液进行漱口。学生们至少每年接受一次龋齿检查，并在公立牙科诊所接受牙科治疗直至九年级。对于没有龋洞的初期龋损不进行修复。
一至九年级（6 - 14岁）恒牙无龋儿童的比例从1974年的13.4%增至1991年的73.0%，在此期间平均龋失补牙数（DMFT）下降了86%。对于12岁儿童，1982年后平均DMFT得分降至每名儿童约一颗牙。对于20岁的成年人，4岁开始进行漱口水方案并持续11年的治疗组与居住在不同地区且未参与含氟漱口水方案的对照组相比，龋失补牙面数（DMFS）存在64%的差异。
4或5岁开始漱口的儿童从该项目中受益最大。该项目成本低廉、易于实施，且受到家庭和教师的广泛接受。公立诊所的保守治疗政策可能是参与者受益的原因之一。
