“…According to the storage, the µTBS of all adhesives agents decreased with time. This may be related to the ability of simplified resin bonding systems to absorb water that plays an important role in hydrolytic degradation of resin-dentin bonds after long-term water storage [16]. Furthermore, the water can infiltrate and decrease the mechanical properties of the polymer matrix by swelling and reducing the frictional forces between the polymer chains, a process is known as "plasticization" [17].…”

BACKGROUND: The durability of dentin-resin interfaces with the universal adhesive system is a crucial characteristic with chemical interactions between the exposed collagen and the adhesive monomers, but it is still compromised with wet and dry mode. AIM: The present study evaluated the effect of dentin wetness and solvents containing of one-step self-etch adhesives on the microtensile bond strength (μTBS) of dentin at different storage times. METHODS: Occlusal dentin of 54 extracted human molars was exposed. Each adhesive agent was applied according to manufacturer instructions to wet and dry dentin surfaces. Composite resin was incrementally built up. Bond strengths to dentin were determined using the μTBS test after water storage for 24 h, 1 month, and 6 months. One-way ANOVA was used to compare between more than two non-related samples. The significance level was set at p ≤ 0.05. RESULTS: Dryness of dentin increases the μTBS with solvent-containing adhesives while decrease the μTBS with solvent-free adhesive. There was an increase in microtensile bond strength values in the case of ethanol water-based self-etch adhesive over time. No statistically significant difference was found among different storage times regarding μTBS for solvent-free adhesive, while a statistically significant difference was found among different storage times in μTBS for solvent-containing adhesives. CONCLUSION: Universal adhesive systems improve the durability and stability of dentin bond strength.

Background:Dual-cured composite resins are similar to self-cured composite resins in some of their clinical applications due to inadequate irradiation, lack of irradiation, or delayed irradiation. Therefore, incompatibility with self-etch adhesives (SEAs) should be taken into account with their use. On the other, the extent of dentin dehydration has a great role in the quality of adhesion of these resin materials to dentin. The aim of this study was to investigate the effect of dentin dehydration and composite resin polymerization mode on bond strength of two SEAs.Materials and Methods:A total of 120 dentinal specimens were prepared from extracted intact third molars. Half of the samples were dehydrated in ethanol with increasing concentrations. Then Clearfil SE Bond (CSEB) and Prompt L-Pop (PLP) adhesives were applied in the two groups. Cylindrical composite resin specimens were cured using three polymerization modes: (1) Immediate light-curing, (2) delayed light-curing after 20 min, and (3) self-curing. Bond strength was measured using universal testing machine at a crosshead speed of 1 mm/min. Data were analyzed with two-way ANOVA and Duncan post hoc tests. Statistical significance was defined at P < 0.05.Results:There were no significant differences for CSEB subgroups with hydrated and dehydrated dentin samples between the three different curing modes (P > 0.05). PLP showed significant differences between subgroups with the lowest bond strength in hydrated dentin with delayed light-curing and self-cured mode of polymerization.Conclusion:Within the limitations of this study, a delay in composite resin light-curing or using chemically cured composite resin had a deleterious effect on dentin bond strength of single-step SEAs used in the study.
