Notes:
The use of specific remineralizing agents in toothpastes may help to prevent caries andtreat dentinal sensitivity. In this study, applied nanotechnologies were used to develop a filler fortoothpastes with remineralizing properties.Carbonate hydroxyapatite nanocrystals, with size, morphology, chemical composition andcrystallinity comparable with that of dentine, were synthesized in mild condition.The remineralizing effect was studied with a scanning electron microscopy putting materials ontothe slices of dentine previously demineralized with ortophosphoric acid. The application of thematerials showed the progressive closure of the tubular openings of the dentine with plugs within10 minutes and a regeneration of a surface mineral layer within 6 hours. This rates ofremineralization seems to be compatible with the development of toothpastes with remineralizingeffect
