Introduction:
Dental caries represents a problem of public health in Morocco and the reduction of this pathology is a priority of the Ministry of Health. The use of fluoride toothpastes is, at present, recognized as being an effective means for the prevention of dental caries.
Material And Methods:
[corrected] The aim of our study was to verify the correspondence of the information marked on packagings with the international standards, but also to determine using potentiometry the quantity of fluorine presents in toothpastes marketed in Morocco from three origins: pharmacies, hypermarkets and ambulant sellers.
Results:
The study concerned 56 toothpastes, 73.2% of toothpastes respect the standards of the concerning WHO dates of manufacturing and lapsing. The type of fluoride was specified only on 67.8% of packagings and the used concentration of fluoride was indicated only in 62.5% of the tested samples. For 56 studied toothpastes, the results revealed that if we take into account standards recommended by the WHO and the European Union, only 57.1% of toothpastes could have an effect dental caries.
Conclusion:
The results of this study show that there is a real need of quality control of fluoride toothpastes sold in Morocco especially those of the itinerant market.

In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a result, EDTA...
