A laboratory evaluation of fluoride dentifrices used in Greece

A laboratory investigation of the fluoride dentifrices commonly used in Greece was done in order to evaluate their caries-preventive potential. The evaluation was based on the determination of the free ionic fluoride and the total soluble fluoride present by a potentiometric fluoride electrode technique. Dentifrices containing MFP, NaF and AlF3 were analyzed. The measured total soluble and free ionic fluoride content were discussed in conjunction with the various dentifrice components. Most of the examined dentifrices were MFP type and the free ionic fluoride was found to vary from 130 to 180 parts/10(6) F-.
