A study on the compatibility between one-bottle dentin adhesives and composite resins using micro-shear bond strength

Abstract

ObjectivesThis study was performed to determine whether the combined use of one-bottle self-etch adhesives and composite resins from same manufacturers have better bond strengths than combinations of adhesive and resins from different manufacturers.Materials and Methods25 experimental micro-shear bond test groups were made from combinations of five dentin adhesives and five composite resins with extracted human molars stored in saline for 24 hr. Testing was performed using the wire-loop method and a universal testing machine. Bond strength data was statistically analyzed using two way analysis of variance (ANOVA) and Tukey's post hoc test.ResultsTwo way ANOVA revealed significant differences for the factors of dentin adhesives and composite resins, and significant interaction effect (p < 0.001). All combinations with Xeno V (Dentsply De Trey) and Clearfil S3 Bond (Kuraray Dental) adhesives showed no significant differences in micro-shear bond strength, but other adhesives showed significant differences depending on the composite resin (p < 0.05). Contrary to the other adhesives, Xeno V and BondForce (Tokuyama Dental) had higher bond strengths with the same manufacturer's composite resin than other manufacturer's composite resin.ConclusionsNot all combinations of adhesive and composite resin by same manufacturers failed to show significantly higher bond strengths than mixed manufacturer combinations.

Evaluation of the micro-shear bond strength of four adhesive systems to dentin with and without adhesive area limitation

“…However, the reproducibility of testing results is affected by various factors regarding the inherent weakness of test institute [3]. Although ISO 11405 [23] strictly stresses that "a limitation of the bonding area is important," in most μ-SBS tests, the step of restricting the area of both the adhesive and the resin was often ignored [22,[24][25][26][27], and only the area of the resin cylinder was taken as the bonding area to calculate the bond strength of tested materials. Therefore, the objective of this study was to compare the bond quality of different adhesive systems by employing the μ-SBS test with and without adhesive area restriction.…”

“…The etch-and-rinse adhesive system and the self-adhesive system are the most frequently employed in clinical works [20]. Before new adhesive materials can be put into clinical use, it must be evaluated through various laboratory methodologies; one such methodology is the μ-SBS test, which is one of the most essential tests for predicting the efficiency of new adhesives [20][21][22]. However, the reproducibility of testing results is affected by various factors regarding the inherent weakness of test institute [3].…”

“…Moreover, the adhesive property of the different adhesives can be distinguished with Method I (Figure 2), but this is not the case for Method II. In most traditional μ-SBS tests [12,13,22,[24][25][26][27], the area of the resin cylinder was taken as the bonding area to calculate the bond strength of the tested materials. Therefore, the higher nominal bond strength was obtained and only if massive improvement in bond quality can be distinguished with method II.…”

Dentin bond strengths of all-in-one adhesives combined with different manufacturers’ flowable resin composites

“…Several previous studies reported the dentin bond strengths of various all-in-one adhesives on the market [7][8][9][10][11] ; however, most studies combined adhesive systems with accompanying resin composites. By contrast, the compatibility of resin composites with the different manufacturer's adhesive systems in terms of the dentin bond strength has not reached a consensus in previous studies [18][19][20] .…”

Influence of EDC on Dentin-Resin Shear Bond Strength and Demineralized Dentin Thermal Properties

“…However, a clear protocol of EDC dentin surface coating is still questionable [ 22 , 23 ]. Little attention has been focused on investigating the influence of EDC on the dentin shear bond strength, one of the most essential, valuable and reliable characteristics for initial screening of new dental adhesive systems [ 30 , 31 ].…”
