“…The method used to test microleakage in this study is in accordance with that done by Anthony H.L et al [13] Some form of thermal stressing is needed in the microleakage study as marginal percolation is caused by difference in the co-efficient of thermal expansion between the dental tissue and the restorative material and by the thermal expansion of fluid occupying crevice between tooth and restoration. [14][15][16] Table 3 shows the mean microleakage of glass ionomer to be higher followed by resin-modified glass ionomer and adhesive resin cement. The higher microleakage of glass ionomer in comparison to that of resin-modified glass ionomer cement may be due to the greater susceptibility of glass ionomer cement to dehydration which is difficult to avoid in an in-vitro study, but also may be explained by the presence of slight water adsorption and expansion with resin-modified glass ionomer cement.…”

“…The manufacturer’s recommendation does not require the prior stage of conditioning the dental substrates, and washing with application of primer and adhesive, as self-adhesive cements are capable of modifying the smear layer and incorporating it into the hybrid layer ( 7 - 10 ). This is because one of its components, the multifunctional acid methacrylate (carboxylic or phosphoric) ( 11 ), has the ability to demineralize the dental substrate, due to its acidity, mainly facilitating the penetration of the resinous component of the cement into the matrix dentin ( 8 ).…”

Background The treatment of dentin before the use of self-adhesive cements is still a crucial point to achieve the best bond strength values. The objective of this study was to evaluate the bond strength between dentin and composite resin using different adhesion strategies with self-adhesive resin cement. Material and Methods Forty healthy third human molars were randomly divided into 4 groups (n = 10): CA (control); application of self-adhesive cement (Rely X U200, 3M ESPE), AD + CA: only application of conventional adhesive (Adper Single Bond 2, 3M ESPE) + self-adhesive cement, AC + AD + CA; conditioning with 37% phosphoric acid for 15 seconds + application of conventional adhesive + self-adhesive cement and AC + CA; conditioning with 37% phosphoric acid for 15s + self-adhesive cement. Blocks made of composite resin (Z250 XT, 3M ESPE) were cemented over dentin. The samples were stored for 24h in distilled water at 37ºC and then were sectioned on a metallographic cutter to obtain tooth picks with approximately 1.0 mm2 in cross section. A universal testing machine was used with a speed of 0.5 mm/min to test the microtensile bond strength,. The fracture patterns were classified as adhesive, cohesive and mixed failures. The data (MPa) were analyzed statistically by One-way ANOVA and Holm-Sidak test (α=5%). Results The AC + AD + CA and AC + CA groups had the highest averages, while the CA and AD + CA groups had the lowest bond strength values. Adhesive failure was prevalent in all groups. Conclusions Conditioning with 37% phosphoric acid for 15s increases the adhesion of the self-adhesive resin cement to the dentin, regardless of the use of dental adhesive system. Key words: Resin cement, microtensile bond strength, acid conditioning.

“…They are also called all-purpose, multipurpose or universal resin cements. These cements are capable of binding to dental tissues without the prior use of a bonding adhesive ( 6 ). This self-adhesive cement consists of multifunctional acid methacrylate (carboxylic or phosphoric) ( 7 ), which can demineralize the dentine due to its acidity, and at the same time, the resin infiltrates the dentine matrix forming a hybrid layer with resin tags without prior removal of the smear layer.…”

AimThe aim of the present study was to determine the shear bond strength of self-adhesive resin cements to enamel and dentin with and without surface treatments, and compare them with conventional resin cement as the control group.MethodsIn this experimental study, buccal and lingual surface of the thirty sound human premolars were polished in order to obtain a flat surface of enamel (E) in buccal, and dentin (D) in lingual. Sixty feldspathic ceramic blocks (2×3×3 mm) were prepared and randomly divided into six groups (n=10). Each block was cemented to the prepared surface (30 enamel and 30 dentin surface) according to different protocol: E1 and D1; RelyX ARC as control group, E2, D2; RelyX Unicem, E3, D3; acid etching +RelyX Unicem. The specimens were termocycled and subjected to shear forces by a universal testing machine at a cross head speed of 0.5 mm/min. The mode of fracture were evaluated by stereomicroscope. Data were analyzed with descriptive statistical methods using SPSS version 15. One-way ANOVA, and post hoc Tukey tests were used to compare bond strengths between the groups with different adhesives at α=0.05.ResultsStatistical analysis showed no significant differences within the enamel subgroups, but there were significant differences within the dentinal subgroups, and statistically significant differences were found between the groups D1and D3 (p=0.02). Comparison between similar enamel and dentinal subgroups showed that there was a significant difference just between the subgroups E3 and D3 (p=0.01).ConclusionElective etching of enamel did not lead to significant increase in the shear bond strength of RelyX Unicem in comparison to RelyX ARC. On the other hand, elective etching of dentin reduces the bond strength of RelyX Unicem with the dentin.
