“…A 30-second or less etching time has been proposed in one study, 8 while another study showed the average bond strength of 1,159 psi between composite and glass ionomer etched for 60 seconds. 4 A third study reports no significant difference between 30-and 60-second etching times. 6 However, surface deterioration of glass ionomer cements following acid etching for longer than 15 seconds has been noted and recommendations for limiting the etching time have been made based on these SEM evaluations.…”

“…[2][3] This technique was developed by McLean and others in 1985; they used the dentin adhesive properties of glass ionomer cements (GICs) to seal cavities and reduce microleakage. 4 This technique benefits from the advantages of GIC fluoride release combined with esthetic resin material to enhance clinical serviceability. 5 However, the bond between conventional GICs and resin composite is limited due to a lack of chemical bonding between the two materials and also the low cohesive strength of glass ionomers.…”

SUMMARYThe current study evaluated the bonding ability of composite to glass ionomer cement (GIC) using three different bonding systems. One hundred samples of composites bonded to GIC were prepared and divided into five groups. In Group A, the composite was bonded to GIC after the initial setting of the GIC being employed as a total-etch adhesive. In Group B, the self-etch primer was employed to bond composite to GIC before the initial setting of the GIC. In Group C, the self-etch primer was employed to bond composite to the GIC after the initial setting of the GIC. In Group D, the GIC-based adhesive was employed to bond composite to the GIC before the initial setting of the GIC. In Group E, the GIC-based adhesive was employed to bond composite to the GIC after the initial setting of the GIC. Shear bond strength analysis was performed at a crosshead speed of 0.5 mm/minute. The results were tabulated and the statistical analysis was performed with one-way ANOVA; the Tukey's test showed that the bond strength of composite to GIC was significantly higher for the self-etch primer group employed on unset GIC and the GIC-based adhesive group employed on the set GIC for bonding composite to GIC. V Gopikrishna • M Abarajithan Clinical RelevanceThe bond strength of resin composite to glass-ionomer cement can be enhanced when a selfetching primer is employed over unset GIC or when a glass-ionomer based adhesive is employed over set GIC when compared to using a total-etch adhesive.

“…Most of the studies on the glass ionomer-composite restorations focus on either their interlayer strength McLean & Gasser, 1985;Sneed & Looper, 1985;Causton, Williams & Sefton, 1986;Hinoura, Moore & Phillips, 1987) or their in vitro sealing efficiency on hard dental tissues (Gordon et Roulet & Rosansky, 1986;Wilson, Watts & King, 1986;Leirscar & Eriksen, 1986). However, the alterations of the surface chemistry of the glass ionomers following acid etching and the morphology of the composite ionomer interface have not been studied properly.…”

The purpose of this study was to assess the surface alterations induced by acid etching on two glass ionomer lining cements (Ketac Bond, G-C lining cement) and to evaluate their interface with a composite resin (Herculite XR) following various surface treatments. The changes in the surface composition and topography of the etched liners were studied by electron microprobe and ESCA analyses. The interfacial treatments performed on the ionomer surfaces were: (i) application of a bonding resin; (ii) 20-s acid etching and application of a bonding resin; (iii) application of a dental adhesive based on a chlorophosphate ester of BisGMA (Scotch-bond LC), without acid etching. The interfacial sealing efficiency of these treatments was studied by the silver nitrate microleakage technique combined with optical and electron microscopy. According to the results the etched surfaces of both the liners present excessive porosity with glass and matrix dissolution. Significant changes in the surface chemistry of the liners were detected indicating severe degradation. The microleakage study revealed interfacial gaps and fractures in the etched samples. The best results were obtained from the non-etched ionomer liners which were subjected to the adhesive treatment. The efficiency of acid etching as a necessary step in the 'layered' technique is seriously questioned.

“…According to Gupta,Mahajan 10 , the bond strength between composite resin and conventional GIC was reduced by the low cohesive strength of the GIC and the absence of chemical bonding, due to the different setting reactions occurring in these materials. Sneed, Looper 20 , considered that the bond strength between composite resin, adhesive system and GIC was greater than the cohesive force of the GIC. Moreover, when the etch-and-rinse adhesive system was used on the conventional GIC, phosphoric acid etching could dissolve surface charged particles 21,22 creating a zone of fragility that resulted in cohesive failure of the material, possibly resulting in lower bond strengths 17,22 .…”

Introduction Glass ionomer cements are often used as a base or cavity lining prior to restorative material. Objective To evaluate the bond strength of a composite resin to different glass ionomer cements, when using a two-step conventional and self-etching adhesive systems. Material and method Three glass ionomer cements (Ketac Molar Easymix, Vitremer and Vitrebond), the composite resin Filtek Z350 XT and the adhesive systems Adper Single Bond 2, Clearfil SE Bond and Adper Easy One were used. As negative control, resin was bonded to cement without using an adhesive system. Holes (4 mm diameter, 2 mm deep) prepared in acrilic bloks were filled with the glass ionomer cements (n=12/group). On the surface, an area of 1mm in diameter was delimited, the adhesive system was applied, and a specimen of composite resin with 1 mm height was made. After 24 hours storage (37 °C and 100% humidity), the microshear test was performed. Data were analyzed using two-way ANOVA and Tukey test for comparison between groups (α=0.05). Result The adhesive systems significantly improved the bond strenght of composite resin to glass ionomer cements (p≤0.001). There was no significant difference in bond strength when self-etching adhesive systems were compared with the simplified etch-and-rinse adhesive, except for Vitrebond where Clearfil SE Bond determined higher bond strength when compared to Adper Single Bond 2 (p=0.003). Conclusion Self-etching adhesive systems are a good option for establishing the bond between the composite resin and the glass ionomer cement.
