ABSTRACT
PURPOSE:
The objective of this study was to compare the light transmittance of zirconia in different thicknesses using various light curing units. MATERIALS ANDMETHODS:
A total of 21 disc-shaped zirconia specimens (5 mm in diameter) in different thicknesses (0.3, 0.5 and 0.8 mm) were prepared. The light transmittance of the specimens under three different light-curing units (quartz tungsten halogen, light-emitting diodes and plasma arc) was compared by using a hand-held radiometer. Statistical significance was determined using two-way ANOVA (alpha=.05).RESULTS:
ANOVA revealed that thickness of zirconia and light curing unit had significant effects on light transmittance (P<.001).CONCLUSION:
Greater thickness of zirconia results in lower light transmittance. Light-emitting diodes light-curing units might be considered as effective as Plasma arc light-curing units or more effective than Quartz-tungsten-halogen light-curing units for polymerization of the resin-based materials.
