ABSTRACT

The purpose of this study is to compare efficiency of broad spectrum LEDs (VALOⓇ, Ultradent, USA) withconventional LED curing lights (EliparTM Freelight 2, 3M ESPE, USA) using a microhardness test. The light curing units used were VALOⓇ in three different modes and EliparTM Freelight 2. The exposure timewas used according to the manufacturer's instructions. After cured resin specimens were stored in physiologicalsaline at 37℃ for 24 hours, microhardness was measured using Vickers microhardness tester. The microhardnessof upper and lower sides of the specimens were analyzed separately by the ANOVA method (Analysis ofVariance) with a significance level set at 5%. At upper side of resin specimens, an increased microhardness was observed in the broad spectrum LED curinglight unit with a high power mode for 4 seconds and plasma emulation mode for 20 seconds (p < 0.05). However, at the lower side of resin specimens, there were no significant differences in microhardness betweenbroad spectrum LED curing light unit and conventional LED curing light unit.
