The evaluation of long-term effects five years after the completion of a school-based caries prevention programme combined with fluoride mouth rinse (FMR) and targeted sealant application (TS).
46 subjects in the FMR+TS group and 55 subjects in the FMR group, who were 20 -21 years old, were analysed. They had participated in each 11-year programme, underwent a dental examination at the age of 20 years and answered a self-administered questionnaire.
The caries prevalence and mean DMFT were calculated, and differences between the two groups were analysed by the chi2 test and Mann-Whitney test, respectively. Logistic and multiple regression analyses were performed using sex, group, and five questionnaire items as independent variables.
The caries prevalence and mean DMFT (SD) was 28.3%, 1.56 (3.00) in the FMR+TS group and 60.0%, 2.20 (2.44) in the FMR group, and the difference was significant respectively. In the logistic regression analysis the odds ratio of the FMR+TS group to the FMR group was 0.28 (p < 0.05).
The caries-preventive effects of a school-based combined programme with FMR and TS continued for more than five years after the programme until the age of 20 years.
评估一项以学校为基础的龋齿预防项目结束五年后的长期效果，该项目结合了含氟漱口水（FMR）和针对性窝沟封闭（TS）。
分析了FMR+TS组的46名受试者和FMR组的55名受试者，他们年龄在20 - 21岁。他们都参与了为期11年的项目，在20岁时接受了牙科检查，并回答了一份自填式问卷。
计算龋齿患病率和平均龋失补牙数（DMFT），两组间差异分别采用卡方检验和曼-惠特尼检验进行分析。以性别、组别和五个问卷项目作为自变量进行逻辑回归和多元回归分析。
FMR+TS组的龋齿患病率和平均DMFT（标准差）分别为28.3%、1.56（3.00），FMR组为60.0%、2.20（2.44），差异均有统计学意义。在逻辑回归分析中，FMR+TS组与FMR组的比值比为0.28（p < 0.05）。
以学校为基础的FMR和TS联合项目的防龋效果在项目结束后持续了五年多，直至20岁。
