      Knight G.M., McIntyre J.M., Mulyani, Bond strengths between composite resin and auto cure glass ionomer cement using the co-cure technique, University of Adelaide, Australian Dental Journal 2006; 51:(2): 175-179.<\/p>\n

      The clinical technique for sandwich restorations prescribes etching initially set auto cure glass ionomer cement (GIC) prior to placing a layer of resin bond to develop a weak mechanical bond between composite resin and GIC. Co-curing a resin modified glass ionomer cement (RMGIC) bond and composite resin to GIC may create a chemical bond and improve the bond strengths between these two materials. Riva LC and Fuji II LC were the two RMGICs used in this study.<\/p>\n

      RMGIC bond and composite resin may be co-cured to GIC either before or after initial set has occurred. There are clinical situations where co-curing prior to initial set may improve the predictability of a restoration and further reduce the time required to place it. Results show pre set co-cure Riva LC has a higher average bond strength value (7.05 MPa) than pre set co-cure Fuji II LC.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner width=”1\/2″][vc_column_text]Request Full Copy<\/a>[\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/2″][vc_column_text]<\/p>\n

      Aim: To compare Class II microleakage in vitro of three different bases placed under composite restorations.<\/p>\n

      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 \u2013 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.<\/p>\n

      Riva Self Cure and Riva Light Cure were more resistant to microleakage than Esthet X on both occlusal-cavo and proximal-cavo surfaces.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner width=”1\/2″][vc_column_text]Request Full Copy<\/a>[\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/2″][vc_column_text]<\/p>\n

      Today, restorative dentistry emphrasizes minimally invasive approaches. This encompasses prevention, remineralization, and when needed, adhesive restorations. These approaches lessen the chance for subsequent adverse outcomes, including advancement of tooth decay, pulpal involvement and tooth fracture.<\/p>\n

      This invitro study evaluated the stain resistance of resin modified glass ionomer over time when exposed to tea, red wine and coffee.<\/p>\n

      Methods: Total of sixty disks, twelve per group, were fabricated using shade A2 of each RMGI material (n=60). Groups: 1-RivaLC(SDI), 2- FujiII-LC(GC America) 3- Riva LCHV(SDI), 4-Photac-FilQuickAplicap(3M ESPE), and 5-KetacNano(3M ESPE). RMGI was dispensed into a 16mm-diameter stainless steel mold, compressed with a mylar strip and glass slide on both sides. Molds were light cured 1min on each side (SDI Radii Plus), and thickness of the disks measured (1.00\u00b10.05mm). Three samples from each material were randomly assigned to red wine, black tea, coffee or unstained (control) and stored at 37\u00baC in de-ionized water for three days. Color and opacity were measured (XRite spectrometer) using the contrast ratio, prior to staining procedure. Water was placed between the disk and substrate to obtain good optical contact. The samples were then transferred to staining solutions and stored at 37\u00baC. After 4 and 5 days, samples were removed from staining solutions, washed with de-ionized water, and opacity and color were measured. Between measurements, the samples were transferred to fresh staining solution and stored at 37\u00baC. The changes in opacity and color were analyzed using ANOVA and Multiple Range Test (LSD,95%confidence level, p-value< 0.05).<\/p>\n

      Conclusions: Staining with beverages affects both color and opacity. Group-5 behaves differently from other RMGIs, which take up red wine and coffee stains to a similar extent. Group-5 takes up more coffee stain than red wine. Clinically, group-5 may be more appropriate for wine and tea drinkers, while the other RMGIs are more appropriate for coffee drinkers.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner width=”1\/2″][vc_column_text]Request Full Copy<\/a>[\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/2″][vc_column_text]<\/p>\n

      Objectives: This in vitro study evaluated the translucency of resin modified glass ionomer cements (RMGIs) compared to leading composites over time.<\/p>\n

      Methods:
      \nMaterials tested were Riva LC A2 (1, SDI), Fuji II LC A2 (2, GC America), Riva LC HV A2 (3, SDI), Photac-Fil Quick Aplicap A2 (4, 3M ESPE), Ketac Nano A2 (5, 3M ESPE), and Filtek Supreme Ultra composite shades A2B, A2E, WE (6, 7, 8, 3M ESPE).<\/p>\n

      Triplicate disks (n=24) were fabricated from each product by dispensing material into a 16mm diameter stainless steel mold, which was covered and compressed with a mylar strip and glass slide on both sides. The molds were light cured for 1min on each side (SDI Radii Plus), and the thickness of the disks were measured (1.00\u00b10.05mm). The disks were stored at 37\u00baC in de-ionized water prior to measurement of their opacity. Opacity was measured using the contrast ratio (CR) method with an XRite spectrometer in an integrating sphere geometry. The CR was obtained by comparing the sample against a black glass background and white tile. Water was placed between the disk and substrate to obtain good optical contact. Measurements were made one hour after preparation, followed by 3 and 10 days.[\/vc_column_text][vc_column_text]Results:
      \nThe opacities were analyzed using ANOVA and Multiple Range Test (LSD, 95% confidence level, p-value < 0.05).<\/p>\n

      Conclusions: Group 1 (Riva Light Cure) is the most translucent of the RMGIs tested. Three days after cure, the opacity of group 1 is similar to group 7 composite. All the RMGIs except group 5 reduce opacity slightly during the first few days after cure. If the RMGIs are used to replace enamel, the reduction in opacity will make the underlying tooth structure slightly more visible.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner width=”1\/2″][vc_column_text]Request Full Copy<\/a>[\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/2″][vc_column_text]<\/p>\n

      Objectives: To investigate the radio-pacity of commercially available glass ionomer cements (GICs), flowable resin composites (FRCs) and calcium hydroxide cements and compared this with the radiopacity of enamel, dentine and aluminium stepwedge.<\/p>\n

      Results: Riva Light Cure and Riva Self Cure showed high to very high radiopacity when compared to competitor brands.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner width=”1\/2″][vc_column_text]Request Full Copy<\/a>[\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/2″][vc_column_text]<\/p>\n
