Influence of alkaline pH on the effectiveness of sodium fluoride dentifrices
Journal of Dental Research
|April 1, 1980
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.
