Abstract
Two similar sodium fluoride dentifrices, one neutral and one alkaline, were compared to a placebo for clinical effectiveness in reducing caries. The neutral dentifrice contained 35% less soluble fluoride than the alkaline dentifrice. Both fluoride dentifrices were significantly effective but were not different from each other.
摘要
将两种类似的含氟牙膏（一种中性，一种碱性）与一种安慰剂进行比较，以评估它们在减少龋齿方面的临床效果。中性牙膏的可溶氟含量比碱性牙膏低35%。两种含氟牙膏都具有显著效果，但彼此之间没有差异。
