This article evaluates the ability of a toothpaste formulation containing calcium, phosphate and a film-building carboxymethyl cellulose to repair and refill damaged enamel. Micro-hardness and elasticity were quantified by nano-indentation, and surface roughness by profilometry. Scanning electron microscopy was employed for qualitative analysis, and profilometry, again, for the refilling of micro damage.
