the cosmetic dentistry request to increase the duration of veneers and crowns to the tooth structure, which increase the cosmetic translucent zirconia duration.
The research objective is to Contrast of shear bond strength of translucent zirconia veneers bond to the enamel among changed light intensity.
Thirty upper-removed premolar was used. Thirty translucent zirconia discs were made according to manufacturing direction then randomly dived into two assemblies. Using bisco choice2 resin cement is light cured. The two assemblies dropped into I group and II group, Group I: low intensity light power has at 1000mW/cm² (10 Sec) used. Group II: high light intensity groups that is high intensity power at 1400 mW/cm² (4 Sec) used.
high significant difference (<0.001) Statistically among groups II and I in means for low intensity assemblies is 10.12 Mpa however the high light intensity assemblies mean 16.97 Mpa.
Giving to this study the high intensity light more efficient bond force of translucent zirconia veneer to the enamel than low intensity light.
