To further complement GC's new composite restorative G-ænial, the company has developed a one component self-etching light cure adhesive, Gaenial BOND. With a belts and braces approach,
G-ænial BOND offers the best of both worlds: the simplicity and reduced post-operative sensitivity of a self-etch adhesive together with the greater bond strength that was traditionally
found only with etch and rinse adhesives. As a one bottle self-etch bonding agent, G-ænial BOND can be used to self-etch both enamel and dentine, however, to further enhance the bond
phosphoric acid can be applied on enamel for ten seconds prior to the application of G-ænial BOND. Selective etching is secure with G-ænial BOND. Test results have shown that there is no
decrease in bond strength to etched dentine, therefore there is no adverse effect if the etchant inadvertently reaches the dentine while etching the enamel. With a selective etching
approach, G-ænial BOND offers the best of both worlds safely: the simplicity and reduced post-operative sensitivity of a self-etch adhesive together with the greater bond strength to enamel
that was traditionally found only with etch-and-rinse adhesives. The dimethacrylate monomer increases G-ænial BOND's permeability into enamel and dentine, while the increased level of
phosphate ester monomer optimises etching. The resulting nano-interaction zone and the HEMA-free formulation are key factors for the superior and long lasting bond strength. READER RESPONSE
