Schoolchildren residing in a fluoride-deficient area were provided either a sodium fluoride (0.1% F) or a nonfluoride dentifrice for home use. About half the children provided each type of dentifrice were also given an initial prophylaxis. Combining the data with regard to the type of dentifrice indicated that the sodium fluoride dentifrice resulted in dental caries reductions of 24 and 26% as noted by the two examiners, respectively.
居住在缺氟地区的学童被提供了氟化钠（0.1%氟）牙膏或非含氟牙膏供家庭使用。使用每种牙膏的儿童中约有一半还接受了初次预防治疗。综合有关牙膏类型的数据表明，两位检查人员分别指出，使用氟化钠牙膏可使龋齿减少24%和26%。
