Effects of accelerated aging cycles on resin cement-glass ceramic bond strength

Aim: A successful restoration is the result of proper adhesion between dental tissue, cement and material. The long-term durability this bond mandatory for clinical success. aim present study to investigate influences three different thermal cycle applications on resin cement-glass ceramic shear strength.
 Methodology: In study, a single CAD/CAM glass block five cements (Panavia V5, RelyX U200, G-CEM LinkForce, Veneer,and Variolink Esthetic) were used. total 240 sections 2 mm in thickness obtained under water cooling precision cutting machine with aid diamond saw. Cementation samples was conducted accordance instructions manufacturer, cemented incubated at 37 °C 24 hours. Afterwards, randomly divided into four groups according cycle: control group, 1750, 3500 7000 cycles (n = 12). Following aging procedures, tested bond. Statistical analyses done by using IBM SPSS 20.0 program. While ANOVA test used intra-group statistical analyses, LSD multi-comparison analysis detection inter-group differences. significance set p < 0.05.
 Results: Although an overall reduction seen all following applications, found be statistically significant Panavia Veneer Esthetic (p<0.05). 1750 application, V5 G-Cem LinkForce dual-cure property showed higher strength than light-cure structure (p<0.05).
 Conclusion: procedure associated absorption interface. So preferred cementation restorations among key parameters success.
