Adhesion is the driving force of the progress in dentistry . Many clinical applications in restorative dentistry are indeed adhesive procedures including the placement or repair of direct and indirect restorations.
In the direct restorative procedures, the main challenge is to achieve robust bonding to tooth structure. Based on the dental substrate, adhesive strategy is selected. Current adhesive strategies include; etch-and-rinse (ER), self-etching (SE) and selective enamel etching (SEE). ER strategy in which phosphoric acid etchant is applied to dental substrate prior to adhesive application is recommended for enamel, while it may be considered an aggressive step to dentin . Acid-etching of dentin activates the matrix metalloproteinases enzymes which may result in degradation of collagen fibrils within hybrid layer which can affect bond strength [3,4]. In contrast to ER, SE strategy do not require the acid-etching step, as they contain acidic monomers that simultaneously ‘condition’ and ‘prime’ the dental substrate .
