Optimization of the etch-and-rinse technique: New perspectives to improve resin –dentin bonding and hybrid layer integrity by reducing residual water using dimethyl sulfoxide pretreatments

Despite the evolution in adhesive dentistry over the past decades [1 –3], degradation of tooth-bonded interfaces [2] still contributes to the reduced long-term clinical success of adhesive restorations [4–6]. Currently, resin–dentin bonding relies on effective adhesive penetration into demineralized collagen matrix for proper hybrid layer formation [2,7]. The h ybrid layer is characterized by the creation of complex collagen-resin biopolymers aiming to provide a continuous and stable link between the bulk adhesive and dentin substrate [1,2].
