New GIC’s (Riva, SDI Ltd.) have been developed with new powder formulations and powder surface treatments designed to give increased fluoride release. The purpose of this work was to compare the new cements (one restorative and one luting) with existing, commercially available products. Three GIC restoratives tested were Riva Self Cure (Fast Set, SDI Ltd / Australia); Fuji IX GP Fast (GC Corp., Japan); KetacTM-Molar Quick AplicapTM (3M, Espe AG / Germany); and three luting GICs: Riva Luting (SDI Ltd. / Australia); Fuji I Capsule (GC Corp / Japan); KetacTM-Cem AplicapTM (3M, Espe AG / Germany). Results:
Throughout the experiment Riva Self Cure and Riva Luting released significantly higher amounts of fluoride than other materials. The results support the hypothesis that the newly developed glass surface treatment has resulted in materials with high fluoride release.
To determine changes in profiles of Ca, P, F and Sr across demineralized dentine following its direct contact with Riva Self Cure GIC using an Atraumatic Restorative Technique (ART) model, and to analyse for any resultant changes in its microhardness. Ion exchange between Riva Self Cure GIC and demineralized dentine compares well with that previously observed when Fuji Ix was used. A high uptake of Sr results in significantly increased microhardness of the demineralized dentine. The chemical and physical form by which Strontium is present in the dentine is not known.
To determine the nature of the interaction between Riva GIC and demineralised dentine, particularly in terms of the movement of strontium and fluoride ion from the GIC into the latter. The study was carried out using the in vitro model of the Atraumatic Restorative Technique (ART) developed by Dr Hien Ngo. Overall, the resultant diffusion patterns for Riva GIC were similar to, or slightly greater than those from Fuji IX for the time of exposure between GIC and demineralised dentine.
Aim: To compare Class II microleakage in vitro of three different bases placed under composite restorations. Method: Thirty-six extracted molars were prepared as Class III MO/DO. 2mm occlusal depth. 2mm axial box depth, 3-5 mm gingival box width and 1 mm gingival margin below CEJ. Teeth were randomly divided into three groups of twelve (groups 1-2 = glass ionomer, group 3=flowable resin): Froup 1-Riva Light Cure GI (SDI). Group 2 – Riva Self Cure GI (SDI), Group 3-Esthet X Flow (Dentsply Caulk). All groups were primed with Clearfil SE Bond Primer and Bond (Kuraray). All samples were then restored using Ice nano-hybrid composite (SDI), finished and polished. Restorations were thermocycled for 300 cycles between 5oC and 55 oC with a dwell of 30 seconds and then placed in 0.5% aqueous basic fuchsin dye for 24 hours at 37 oC . Samples were sectioned mesiodistally and scored independently by two evaluations for microleakage at the occlusal-cavo and proximal-cavo surfaces under a 40x stereomicroscope. Dye penetration was evaluated using a scoring system: 0=no penetration, 1=penetration in enamel/cementum. 2=penetration at the axial wall, 3=penetration beyond the axial wall. Riva Self Cure and Riva Light Cure were more resistant to microleakage than Esthet X on both occlusal-cavo and proximal-cavo surfaces.

No. 3; p60 – 68, 2008. The aim of this study was to evaluate the influence of ultrasonic treatment on the microhardness of nine commercially available brands of glass-ionomer cements. Conclusion: Ultrasonic command setting improved the microhardness of the glass-ionomer cements. Ultrasonic treatment accelerated surface hardening which might reduce early weakness of glass-ionomer restorations. The microhardness of Riva SC and competitors significantly increases after ultrasonic treatment.
Pereira L.C.G., Borges D.L.M.; Lima A.A., Barata T.J.E., Navarro M.F.L.; Clinical evaluation of ART restorations usng two different insertion techniques; Toronto IADR 2008, Abstract #1773, University of North Parana, Sao Paulo, Brazil. The aim of this study was to evaluate restorations made with two different insertion techniques of a glass ionomer cement (Riva Self Cure) using the Atraumatic Restorative Treatment (ART) in permanent teeth. The study was conducted in nine schools of Anapolis/Brazil. Conclusion: The restorations performed with encapsulated GIC (Riva Self Cure) survived longer than those produced with the hand-mixed GIC in the permanent teeth. The microhardness of Riva Self Cure and competitors significantly increases after ultrasonic treatment.
Knight G.; Co-curing - Better, Faster, Easier Dentistry; Shine, New Zealand, Winter/Spring 2008. Clinical words and images from Dr Geoff Knight using Riva Self Cure and Riva Light Cure in the co-curing technique. This technique uses resin modified glass ionomer cement (Riva Light Cure) as a bonding intermediary between the glass ionomer cement, Riva Self Cure (either uncured or cured) and the composite resin. Hence the name co-cure.
Santos E.M., Guedes C.C., Motta L.J., Bussadori S.K.; Cytotoxic effects of ionomers glass in ll cultured; Abstract #0471, Toronto IADR 2008, Universidade deMogi Das Cruzes, Sao Paulo, Brazil. Objectives: To evaluate the cytotoxicity of Ketac Molar easymix (3M), Maxxion R (FGM), Riva Self Cure (SDI), Vitro Molar (DFL) using in vitro assays. Conclusion: The study established reduced cytotoxicity of polymerized materials compared to their unpolymerized state.
Freedman G; First Impressions - Riva Self Cure; Dentistry Today, February 2010. Dr George Freedman is a founder and past president of the American Academy of Cosmetic wrote his first impressions of Riva Self Cure. He described it as a "truly innovative ionomer restorative material with a proprietary high ion releasing reactive glass filler. "
Costa C. A. S. et al.; Pulp response after application of Riva Light Cure and Riva Self Cure glass ionomer cements in deep cavities prepared in human teeth; University of Estadual Paulista Julio de Mesquita Filho, Final Report, November 2010. Aim: To evaluate the dental pulp response after restoration of deep cavities with resin-modified glass-ionomer cements, Riva Light Cure, Riva Self Cure and Dycal (control). Results: At 7 days, 3 samples restored with Riva SC presented mild inflammatory reaction mediated by mononuclear cells and a number of small blood vessels adjacent to the odontoblasts. However, at 30 days, no inflammatory pulp response was observed in all samples evaluated.

An English version is also available. Dr Susanne Linb introduced the co-cure technique to readers as an viable alternative method to surgery-fabricated inlays or onlays.
Performance Comisi J.; Using Bioactive Materials to achieve Proactive Dental Care; Oral Health Group, p. 34-46, December 2011. Resin bonding of the human dentition has become a "standard" in the United States and Canada. There are well over 80 different bonding systems on the market today. We have seen them evolve through multiple generations in an attempt to "simplified" the bonding process. But as these agents have simplified, many in our profession have seen many challenges "pop up". Dr Comisi presented a radical approach to direct posterior restorations, called the "Co-Cure" Technique. This technique is defined as the simultaneous photo-polymerization of two different light activated materials which involves "the sequential layering of GIC, RMGIC and composite resin prior to polymerization and before the initial set of the GIC (which) enables an efficient single visit placement of a (direct) restoration.
