“…14 Water in excess can dramatically affect the adhesive performance of acetone-based adhesives to a greater degree than in alcohol-based ones. 13,14 Interestingly, on the contrary, according to Jacobsen and Söderholm, 45 the water-based adhesives can result in lower adhesive bond strength when compared with adhesives with alcohol or acetone since excess water can jeopardize adhesive polymerization. The moisture amount of the substrate is, therefore, extremely important for dentin hybridization and tag formation.…”

“…In an in vivo study, Abdalla and García-Godoy 12 showed that superior performance in resin tags and hybrid layer formation was achieved with a water-based adhesive compared with an acetone-based one, possibly due to higher sensitivity of the latter technique. 13,14 Therefore, resin tags can be longer or shorter depending on the solvent influence to yield a better or worse penetration of the resin in the dentinal tubules. 6 The low viscosity of the primers and/or adhesive resin is partly due to the dissolution of the monomers in a solvent, which leads to an improvement in its wettability.…”

Aim:The study aimed to analyze the morphology of the dentinresin interface yielded by two-step etch-and-rinse adhesive systems with different solvents and compositions. Materials and methods:A total of 32 dentine disks were prepared and randomly assigned to four groups of one-bottle etchand-rinse adhesive systems containing different solvents: group I, Adper Scotchbond-1XT™ (ethanol/water); group II, XP-Bond™ (tertiary butanol); group III, Prime and Bond NT ® (acetone); and group IV, One Coat bond ® (5% water). Adhesive systems were applied onto dentin disks, which were then thermal cycled, divided into two hemi-disks (n = 16), and prepared for field-emission scanning electron microscopy to examine the dentin-resin interdiffusion zone. Microphotographs were scanned and data were processed. Data were compared with analysis of variance multivariant test after Kolmogorov-Smirnov and Shapiro-Wilk tests using Statistic Package for the Social Sciences. Results:The adhesive layer thickness average found was group I: 45.9 ± 13.41 µm, group II: 20.6 ± 16.32 µm, group III: 17.7 ± 11.75 µm, and group IV: 50.7 ± 27.81 µm. Significant differences were found between groups I and IV and groups II and III (p < 0.000).Groups I (3.23 ± 0.53 µm) and II (3.13 ± 0.73 µm) yielded significantly thicker hybrid layers than groups III (2.53 ± 0.50 µm) and IV (1.84 ± 0.27 µm) (p < 0.003). Group III presented a less homogeneous hybrid layer, with some gaps. Tag length average was greater in groups II (111.0 ± 36.92 µm) and IV (128.9 ± 78.38 µm) than in groups I (61.5 ± 18.10 µm) and III (68.6 ± 15.84 µm) (p < 0.008). Conclusion:Adhesives systems with different solvents led to significant differences in the dentin-resin interface morphology. Solvents role in adhesives bond strength should be considered together with the other adhesive system components. Morphology of the Clinical significance:The adhesive containing tertiary butanol, in addition, seems to originate a good-quality hybrid layer and long, entangled tags and also appears to have greater ability to originate microtags, which may indicate higher bond strength.

“…In the total-etching system, gingival bleeding can occur after rinsing off the phosphoric acid gel, coincidentally coming into contact with cavosurface margins 1,2,20) . In vitro shear bond strength testing is commonly used to quantitatively analyze and rank the performance of adhesive systems on enamel and dentin 26,27) . The SBS test is a simple procedure for the experimental evaluation of adhesives system 28) .…”

“…Moreover, in view of the great variety of bonding materials, resin composites, and compomers available on the market, further studies are required to identify differences in the results between products 56 . For example, further in vivo studies with total‐etch filled adhesive systems may identify if the higher viscosity of filled bonding systems will result in lower bond strengths to enamel than one‐bottle adhesive systems without filler particles 57 . Moreover, the concentrations and characteristics of individual monomers in adhesives and their interactions may also affect the extent of infiltration, ionization, and cross linking obtained on polymerization and thus, the mechanical properties of the adhesive 53 .…”
