Resin bonding to dentine after casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) treatments

Abstract

Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) has the ability to enhance enamel and dentine remineralisation and thus has been incorporated in new medicaments for such clinical problems as tooth hypersensitivity and early carious lesions. The current study investigated whether the application of CPP-ACP in the proprietary paste, Tooth Mousse™, would influence the subsequent resin adhesion to dentine. Bonding effectiveness was assessed by microtensile bond strength test and scanning electron microscopy. A three-step etch-and-rinse adhesive (OptiBond FL) or a two-step self-etch adhesive (Clearfil SE Bond) was bonded to three groups of dentine surfaces: no treatment; 5 min or 5 da..
