Objectives:
This study evaluated the influence of different shades of flowable resin composite used as luting agent on the final shade of porcelain veneers of different opacities over A2 and B1 simulated dental substrate.
Materials And Methods:
One millimeter monolithic (enamel E1.0 or dentin D1.0) and bilayer (E0.5D0.5) porcelain discs shade A2 were paired with flowable resin composite disks (0.1 mm thick) of different shades (A1, A2, B1, white opaque - WO or IL - translucent), as veneer + luting agent (n = 10). The CIE L*a*b* color coordinates were measured with a spectrophotometer over white and black standard background, as well as over A2 and B1 simulated dental substrates. Translucency of all specimens and the shade matching of the pairs over the A2 and B1 substrates (ΔE*00 ) were calculated by Translucency Parameter and CIEDE2000 methods. Data were statistically analyzed by 95% confidence interval.
Results:
Porcelain veneer E1.0 groups were the most translucent, while the pairs veneer + luting agent WO showed the lowest translucency, and A1, A2, B1, and IL yielded little to no differences in translucency of the pairs. The overall best shade matching with A2 substrate was observed for D1.0 veneer + WO luting agent.
Conclusion:
The opacity of the porcelain veneer paired with luting agents of different shades affected the final appearance of the restorations over distinct simulated tooth substrates.
Clinical Significance:
Distinct shades of flowable resin composites used as luting agent might yield clinically visible color differences on porcelain veneers facilitating an excellent shade match with adjacent teeth. (J Esthet Restor Dent 28:295-303, 2016).
