Children with a high prevalence of dental caries living in a community with fluoridated water had received semi-annual half-mouth applications of one of two fluoride varnishes for three years. Two years after the applications were discontinued, we studied the post-treatment effect of the varnishes. The absolute reduction in caries found during the treatment was retained, but the cariostatic effect did not continue after treatment. This finding suggests that fluoride varnish applications should not be discontinued after three years.
生活在饮用含氟水社区的龋齿高发儿童接受了为期三年的每半年一次半口涂抹两种氟化物清漆之一的治疗。在停止治疗两年后，我们研究了清漆的治疗后效果。治疗期间发现的龋齿绝对减少量得以保持，但治疗后防龋效果并未持续。这一发现表明，氟化物清漆的涂抹不应在三年后停止。
