“…A 2-step etch-and-rinse adhesive resulted in marginal sealing that was comparable to 2-step self-etch adhesives. In our clinical trial [27,28], there was no significant difference between Liner Bond II (2-step self-etch) and Single Bond (2-step etch-and-rinse) when it came to 8-year survival rates. As predicted by the laboratory test [18], marginal discoloration occurred at both enamel and dentin margins for Liner Bond II, whereas discoloration occurred mainly at the dentin margins for Single Bond.…”

“…Long-term clinical trials demonstrated that the shape, size and location of NCCLs and the degree of sclerosis did not affect clinical performance [28,34,[37][38][39]. In addition, our clinical trial revealed that the size and depth of NCCLs had no influence on marginal discoloration [32].…”

“…The newer1-step self-etch adhesives improved marginal sealing and some products showed equivalent marginal sealing to that of 2-step self-etch adhesives, as shown in Table 11 [26]. Our clinical trials [27,31], which were performed using almost the same protocol, indicated that although there was no difference in 5-year survival rates between adhesives, the incidence and extent of marginal discoloration associated with the 1-step self-etch adhesives were greater than that of other 2-step adhesives. In addition, marginal discoloration of 1-step self-etch adhesives mainly occurred at enamel margins.…”

“…Although many clinical trials have been done, most clinical trials have assessed NCCLs over a time frame of less than 3 years. Therefore, we have been performing clinical trials of resin composite restorations in NCCLs over as long a period of time as possible [28,31,32]. Recently, several long-term (7 years or more) clinical trials of NCCLs have been published [33][34][35][36][37][38][39].…”

“…For the benefit of public oral health, the clinical longevity of restorations for NCCLs requires an urgent improvement. In order to get more insight into this clinical problem, we first performed a series of laboratory studies on clinical placement techniques of cervical resin composite restorations by means of microleakage tests [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] and then we have been conducting clinical trials [27][28][29][30][31][32]. The aim of this article is to discuss the challenges we faced in the clinical placement and evaluation of cervical resin composite restorations as they relate to clinical studies, especially recently published, long-term clinical trials [33][34][35][36][37][38][39].…”

Objectives: The incidence of non-carious cervical lesions (NCCLs) has been increasing.The clinical performance of resin composites in NCCLS was previously unsatisfactory due to their non-retentive forms and margins lying on dentin. In order to address this problem, a lot of effort has been put into developing new dentin adhesives and restorative techniques. This article discusses these challenges and the criteria used for evaluating clinical performance as they relate to clinical studies, especially long-term clinical trials. Polymerization contraction, thermal changes and occlusal forces generate debonding stresses at adhesive interfaces.Methods: In laboratory studies, we have investigated how these stresses can be relieved by various restorative techniques and how bond strength and durability can be enhanced. Lesion forms, restorative techniques, adhesives (adhesive strategies, bond strengths, bond durability, and the relationship between enamel and dentin bond strengths) were found to have a complex relationship with microleakage. With regard to some restorative techniques, only several short-term clinical studies were available.

Recent advances in the theory and mechanism of adhesive resin bonding to dentin: A critical review

Dentin bonding issues involving adhesive resins have attracted considerable research interest in recent years. An important advance due to the ongoing research is the concept of hybridization of the tissue with primer/adhesive systems. Hybridization involves permeation of primer monomer into the tissue substrate. Although the mechanism of adhesive permeation and interaction with tissue may be complex, significant advances have been made. In systems where etching precedes priming and bonding steps, the Hoy's solubility parameter compatibility of the primer formulation with that of demineralized dentin matrix may determine adhesive permeability. Monomer permeation brings the primer atoms in closer contact with the substrate atoms, leading to adhesive interactions through van der Waals, hydrogen bonding, and electrostatic interactions. In self-etch primer systems, stronger electrostatic interaction between primer monomers and hydroxyapatite has been used to explain the adhesion process. These interactions have been computer-modeled and analyzed. Such interactions and subsequent polymerization of the monomer promote improved bond strength and efficient margin sealing. Incomplete permeation of monomer into the full depth of demineralized region may, however, leave exposed collagen fibrils and cause nanoleakage of water into these regions through a 20-100 nm sized marginal gap, leading to subsequent hydrolytic degradation of these collagen fibrils and the hybrid layer. Microleakage is also a problem in some single step formulations. In this review, we analyze these current theoretical and mechanism-related issues of interest in adhesive resin bonding to dentin, and outline the continuing problems that need to be overcome in the future.
