“…Furuse et al 25) applied five different adhesive systems including SB2 and CSE and found no statistical difference between μSBS of resin composite to the wet and dry enamel surfaces. Similarly, Chuang et al 26) reported that marginal quality was not affected when SB2 was applied on dry and wet enamel. However, in both studies wetness of the enamel surfaces were constituted with water contamination.…”

This study tested whether exhaled humid conditions would affect the adhesion of etch-and-rinse, two-step and one-step self-etch adhesive resins to enamel. Enamel surfaces of human maxillary anterior teeth (N=240, n=20) were exposed to four humid conditions (H1: 63-68%, H2: 73-78%, H3: 93-98%, H4: 36-45% RH) during bonding with Adper Single Bond 2 (SB2), Clearfil SE Bond (CSE) and Adper Easy Bond (AEB). Specimens were stored in distilled water at 37ºC for 24 h and tested to failure using micro-shear bond strength (μSBS) test. Data were analyzed using two-way ANOVA and Tukey's test (p<0.05). The μSBS to enamel with SB2, CSE and AEB was not significantly affected by humidity parameters. AEB resulted in significantly lower μSBS in all conditions. The frequency of adhesive failures was the highest at H2, H3 for SB2, H3 for CSE and H1-4 for AEB indicating that humidity conditions may decrease adhesion quality to enamel.

“…The discrepancy between bond results and failure types could be as a consequence of different hydrophilic characteristics of the adhesives as discussed above. Chuang et al 26) observed more cohesive failures in dry enamel and adhesive failures in wet enamel specimens after the application of total-etch adhesive system.…”

“…These teeth were then embedded in acrylic resin using plastic mounting cups (Buehler Sampl-Kup, Buehler, Lake Bluff, IL) and subsequently sectioned longitudinally mesiodistally into halves. One half of each tooth was randomly chosen to be used in Part I for measuring the marginal quality and enamel microcrack under various adhesive conditions, 19 while the other half was treated with the same adhesive, but subjected to enamel bond test. The temporary filling material was removed from the halves for the bond test and they were embedded in epoxy resin to expose the buccal or lingual surfaces.…”

“…Results showed that poor cavity adaptation corresponded to low bond strength. 18 In Part I of this study, 19 we examined the marginal quality and enamel microcrack around composite restorations with different DBAs on either dry and wet enamel. The scanning electron microscope (SEM) examination showed that restorations using self-etching primer exhibited inferior marginal sealing immediately post-restoration to the stage after thermocyclic loading.…”

“…Bond strength may be reduced if the tooth is contaminated with saliva during adhesive procedures. 9 However, the influence of water after enamel etching and before application of the adhesive has not been thoroughly defined, 10,11 especially in relation to self-etching adhesives. With selfetching adhesives, the composition includes not only hydrophilic monomers but also water and organic solvents such as acetone and ethanol.…”

The enamel surface should not be desiccated extensively when an all-in-one self-etching adhesive is employed. SUMMARYObjective: To evaluate, through the application of different dentin bonding systems, the influence of wetness on shear bond strength in enamel.Methods: This study evaluated three etch-andrinse adhesive systems (Scotchbond MP [used with and without primer]; Singlebond; and Prime&Bond 2.1) and two self-etching adhesive systems (Clearfil SE Bond; and Xeno IV). Flat bovine enamel surfaces were either airdried for 30 seconds or blotted with absorbent paper after acid-etching for the conventional bonding agents or before the application of self-etching bonding agents. The resin composite EsthetX was bonded to flat surfaces that had been treated with one of the adhesives, following the manufacturer's instructions. After being stored in water at 378C for one week, bonded specimens were broken in shear. Data were evaluated with two-way analysis of variance (ANOVA) and Student-Newman-Keuls tests (a¼0.05). For comparing each condition , 2011, 36-3, 274-280 individually, regardless of the adhesive or wetness condition, a one-way ANOVA and a Student-Newman-Keuls test (a¼0.05) were applied.Results: The two-way ANOVA showed significant differences among adhesive systems. An interaction effect was also observed (p,0.05), but wetness did not influence shear bond strength (p¼0.98). The one-way ANOVA showed that the all-in-one adhesive was the only material influenced by the presence of water at the enamel's surface.Conclusion: The all-in-one adhesive behaved differently depending on whether the enamel surface was dry or wet.
