An Analysis of Fluoride Concentration in Dentifrices

Abstract:

Objectives: The purpose of this investigation was to determine if the fluoride concentration in dentifrices sold in "dollar" discount stores differs from the fluoride concentration in dentifrices sold in major retail establishments and have earned the American Dental Association's Council of Therapeutics Seal of Approval.

Background: Fluoridated dentifrices have an essential role in any program designed to prevent dental caries in populations, communities, and individuals. The efficacy of fluoride dentifrices is critically influenced by several factors, namely: fluoride rinsing behavior, with concentration being one of the most critical factors.

Methods: This study was an in vitro study that observed fluoride concentrations in ten samples from “dollar stores” and two samples that contain the ADA Seal of Approval. A fluoride ion selective probe was utilized with Total Ionic Strength Adjustment Buffer II to determine fluoride concentrations.

Results: The results of this study revealed that the dentifrice samples containing sodium fluoride ranged from 1037.89 ppm to 1193.31 ppm. According to the ADA guidelines, the sodium fluoride concentration should be between 900 and 1200 ppm.

Conclusion: Fluoride levels were found to be stable in the "dollar brands" and ADA sealed dentifrices. The sodium fluoride concentrations are consistent with the amount of concentrations of fluoride listed on the box. The types of fluoride contained in "dollar brand" dentifrices varied within brands
