This study modelled the cost-effectiveness, from a societal perspective, of a program that used fluoridated milk to prevent dental caries in children who were 6 years old at the beginning of the program, versus non-intervention, after 6 years.
After 6 years, children in the milk-fluoridation program had a significant (34%) reduction in dental caries experience compared to those in the comparison community (i.e., received school milk without added fluoride) (DMFS: 1.06 vs. 1.60).
This improvement was achieved with an investment of Thailand Baht (THB) 5,345,048 over 6 years (or THB 11.88 per child, per year) (1 US$ = THB(2011) 30.0). When comparing the costs of the operation of the program and dental treatment in the test community with those of the comparison community, the program resulted in a net societal savings of THB 8,177,179 (range 18,597,122 to THB 7,920,711) after 6 years. This investment would result in 40,500 DMFS avoided in a community with a childhood population of 75,000 [DMFS avoided: 75,000 x (- 0.54)].
While the analysis has inherent limitations due to its dependence on a range of assumptions, the results suggest that, from a societal perspective, when compared with the non-intervention group, the Bangkok Metropolitan Administration intervention appeared to be a more cost-efficient option than current standard oral health care.
本研究从社会角度对一项使用加氟牛奶预防项目开始时6岁儿童龋齿的项目与6年后不干预的成本效益进行了建模。
6年后，与对照社区（即饮用未添加氟化物的学校牛奶）的儿童相比，参与牛奶加氟项目的儿童龋齿经历显著减少（34%）（DMFS：1.06对1.60）。
通过在6年内投资5,345,048泰铢（或每名儿童每年11.88泰铢）（1美元=2011年30.0泰铢）实现了这一改善。将测试社区项目运营成本和牙科治疗成本与对照社区的成本进行比较时，该项目在6年后为社会带来了8,177,179泰铢的净节省（范围为18,597,122泰铢至7,920,711泰铢）。在一个儿童人口为75,000的社区中，这项投资将避免40,500个DMFS [避免的DMFS：75,ooo×（- 0.54）]。
虽然由于依赖一系列假设，该分析存在固有局限性，但结果表明，从社会角度来看，与非干预组相比，曼谷市政府的干预措施似乎比当前标准口腔保健更具成本效益。
