本研究的目的是比较含氟浓度为250ppm和1450ppm的两种氟化钠牙膏对幼儿园儿童乳牙期的防腐效果。共有319名儿童参与了这项研究(低氟组155名，高氟组164名)，并在幼儿园的监督下每天刷牙。这些儿童由一名按照O‘Mullane等人的程序接受培训的牙医进行检查，并根据WHO标准在空洞水平记录龋损。在22个月后的最终检查中，这些组包括83名(低氟组)和89名(高氟组)儿童。两组间平均DMFS和DMFT增量差异无统计学意义。在这两组儿童中，约57%的儿童保持无龋齿。将这些儿童排除在分析之外，高氟组的平均DMFS增量显著较低，但不是平均DMFT增量。除咬合面外，高氟组的平均DMFS增量明显较低。
The purpose of the study was to compare the anticaries effects of two dentifrices containing sodium fluoride with fluoride concentrations of 250 ppm and 1450 ppm on the primary dentition of kindergarten children. A total of 319 children participated in the study (155 in the low-fluoride and 164 in the high-fluoride group) and brushed their teeth daily under supervision in their kindergartens. The children were examined by one dentist trained according to the procedures of O'Mullane et al., and carious lesions were recorded at the cavitation level according to the WHO criteria. At the final examination after 22 months, the groups comprised 83 (low-fluoride group) and 89 (high-fluoride group) children. The differences in mean dmfs and dmft increments between the two groups were not statistically significant. In both groups about 57% of the children remained caries free. Excluding these children from the analyses, the mean dmfs increment was significantly lower in the high-fluoride group, but not the mean dmft increment. The mean dmfs increment excluding occlusal surfaces was significantly lower in the high-fluoride group.
