Caries-preventive effect of anti-erosive and nano-hydroxyapatite-containing toothpastes in vitro

Objectives The aim of the study was to investigate the caries-preventive effect of newly developed fluoride and fluoride-free toothpastes specially designed for erosion prevention. The hypothesis was that these products might also show superior caries-inhibiting effect than regular fluoride toothpastes, since they were designed for stronger erosive acid challenges.
