Since 2000, a community water fluoridation program (CWFP) has been implemented in Hapcheon for over 15 years. We aimed to evaluate the caries-reducing effect on permanent teeth after this implementation. In 2015, evaluation surveys were conducted by our study group, 498 subjects aged 8, 10, 12, and 15 years. As the control, 952 similarly aged subjects were selected from the Sixth Korean National Health and Nutrition Examination Survey (2013-2015 KNHANES). Data of a prospective cohort of 671 8-,10- and 12-year-olds, collected when CWFP started, were used for the evaluation. Caries-reducing effects were estimated by decayed, missing and filled teeth (DMFT) scores between CWFP and control groups, pre- and post-program. Confounders including the mean number of sealant teeth and gender were adjusted for. The mean adjusted DMFT scores of 10-, 12- and 15-year-olds in Hapcheon were significantly lower compared to KNHANES DMFT scores; in addition, those of 8-, 10- and 12-year-olds after the 15-year CWFP were significantly lower than in 2000. The caries-reducing effect among 12-year-olds was 37.6% compared to those recorded in KNHANES, and 67.4% compared to those in 2000. In conclusion, the caries-reducing effect was so high that health policy makers should consider CWFP as a priority policy for caries-reducing in Korean children and adolescents.
自 2000 年以来，海兵市已实施社区饮水氟化项目（CWFP）超过 15 年。我们旨在评估该项目实施后对恒牙龋病的预防效果。2015 年，我们的研究小组对 498 名 8、10、12 和 15 岁的学生进行了评估调查。作为对照，我们从 2013-2015 年的第六次韩国国家健康和营养检查调查（2013-2015 KNHANES）中选择了 952 名年龄相似的学生。我们还使用了在 CWFP 启动时收集的 671 名 8、10 和 12 岁前瞻性队列的数据进行评估。通过比较 CWFP 组和对照组的龋齿、缺失和补牙（DMFT）评分，评估龋病预防效果。对包括平均窝沟封闭牙数和性别在内的混杂因素进行了调整。与 KNHANES 的 DMFT 评分相比，海兵市 10、12 和 15 岁学生的平均调整 DMFT 评分明显较低；此外，经过 15 年的 CWFP 后，8、10 和 12 岁学生的 DMFT 评分明显低于 2000 年。与 KNHANES 相比，12 岁学生的龋病预防效果为 37.6%，与 2000 年相比为 67.4%。总之，龋病预防效果非常显著，决策者应考虑将 CWFP 作为韩国儿童和青少年龋病预防的优先政策。
