GJORGIEVSKA, Elizabeta S  e  NICHOLSON, John W. A preliminary study of enamel remineralization by dentifrices based on RecaldentTM (CPP-ACP) and NovaMin® (calcium-sodium-phosphosilicate). Acta odontol. latinoam. [online]. 2010, vol.23, n.3, pp.234-239. ISSN 1852-4834.

The purpose of this study was to investigate the enamel remineralization potential of two toothpastes, one of which was based on RecaldentTM (CPP- ACP) and the other on NovaMin® (Calcium-sodium-phosphosilicate). Human permanent molar teeth were subjected to three consecutive demineralization cycles. These cycles were followed by remineralization of the experimental groups by toothpastes containing RecaldentTM and NovaMin® respectively. The samples were analyzed by Scanning Electron Microscope, (SEM) and energy-dispersive X-ray spectroscopy analysis (EDX). Extensive demineralization was noted in the control group (without remineralization) while the groups treated with the dentifrices demonstrated various degrees of remineralization, as shown by formation of different types of deposits on the enamel surface. The EDX analysis showed increased amounts of Ca, P, Si and Zn in the enamel of the experimental groups, compared to the control one. Toothpastes containing RecaldentTM and especially NovaMin® have the potential to remineralize enamel, a property which might be important in finding a substitute to pit and fissure sealing.
