The purpose of this study was to evaluate the surface microhardness in giomer blocks photopolymerized with 3 types of LED lamps and with different photopolymerization protocols. 40 specimens divided into 4 groups were evaluated. Group 1, specimens light-cured with VALO Grand LED lamp at 1200 mW/cm2 for 10 seconds. Group 2, specimens light-cured with VALO Grand LED lamp at 3200 mW/cm2 for 2 seconds. Group 3, specimens photopolymerized with Curing Pen-E lamp at 2800 mW/cm2 for 5 seconds. Group 4, specimens photopolymerized with I-Led lamp at 2200 mW/cm2 for 5 seconds. To make the test bodies, preformed 2x5mm cylinders were used. The results show that group 1 had the highest microhardness values, while group 4 had the lowest values. Statistical analysis was performed with Shapiro Wilk, two-way ANOVA, Levene's Homogeneity Test and Post Hoc Comparison Test with a significance level of < .001. It is concluded that group 1 (VALO Grand with conventional protocol) obtained the highest values of surface microhardness, justified by the total radiation time.
