The anticaries effect of repeated toplications with APF gel was assessed in the primary dentition of 2-6-year-olds after 8, 18 and 28 months. Frequent, but less than daily, topical fluoride therapy appeared to have little effect in pre-school children consuming water-borne fluoride and receiving other traditionally recommended modalities of prevention.
在2至6岁儿童的乳牙列中，于8个月、18个月和28个月后评估了重复涂抹含氟磷酸凝胶的防龋效果。对于饮用含氟自来水并接受其他传统推荐预防措施的学龄前儿童，频繁但少于每日一次的局部用氟治疗似乎效果甚微。
