The purpose of this study was to evaluate the long-term caries preventive effects of school-based fluoride mouth rinse (FMR) program in adults aged 20 years and older. 637 mothers aged from 20 to 39 years were surveyed. Clinical examinations were carried out for subjects to obtain data on dental caries prevalence when they visited local health centers to take their children for medical and dental check-ups at 1.5- or 3-years old. We also obtained information regarding the FMR program: the duration that the subjects participated between nursery school and junior high school. When analyzing data, subjects were divided into 4 groups: FMR from nursery to junior high school group (N-JH group, n=22), FMR limited to the elementary school group (El group, n=62), FMR no-experience group (n=545), and other subjects whose FMR experience is not clear (n=8). For evaluation of the FMR program effect, multiple regression analysis was used. As independent variable, the FMR program patterns were converted into dummy data, and mean DMFT was used as dependent variable. The results of multiple regression analysis between mean DMFT and FMR program patterns showed that the N-JH group and El group were negatively associated with the mean DMFT (ß=-0.20, p<0.001 for N-JH group and ß=-0.11, p=0.003 for El group).The positive caries preventive effects of school-based FMR program from nursery school to junior high school can continue in adults aged 20 years and older.
本研究的目的是评估以学校为基础的含氟漱口水（FMR）项目对20岁及以上成年人的长期防龋效果。对637名年龄在20至39岁之间的母亲进行了调查。当这些受试者带孩子到当地卫生中心进行1.5岁或3岁的医疗和牙科检查时，对其进行临床检查以获取龋齿患病率数据。我们还获取了有关FMR项目的信息：受试者在幼儿园到初中期间参与该项目的时长。在分析数据时，受试者被分为4组：幼儿园到初中使用FMR组（N-JH组，n = 22）、仅小学使用FMR组（El组，n = 62）、未使用FMR组（n = 545）以及FMR使用经历不明确的其他受试者组（n = 8）。为评估FMR项目效果，采用多元回归分析。作为自变量，FMR项目模式被转换为虚拟数据，平均龋失补牙数（DMFT）用作因变量。平均DMFT与FMR项目模式之间的多元回归分析结果显示，N-JH组和El组与平均DMFT呈负相关（N-JH组β = -0.20，p < 0.001；El组β = -0.11，p = 0.003）。从幼儿园到初中以学校为基础的FMR项目的积极防龋效果在20岁及以上成年人中可以持续。
