SUMMARY:

This study aimed to evaluate the influence of different photopolymerizers on the GC of two light-cured resin cements (Variolink® Esthetic LC e Rely X Venner®) e of two light-cured resin cements (Variolink N base® e Rely X Ultimate®) under ceramic matrix through Fourier Transform Infrared Spectroscopy (FTIR).  192 specimens of resin cement were made with 5 mm in diameter and 1 mm in thickness, with 48 samples for each type of cement. Half of the samples from each group (n=24) were photopolymerized using Radii Cal monowave light (LED A) and the other half using Valo Grand Cordless polywave (LED B) with the interposition of IPS e.max® Press ceramic discs in the 1.5 mm thick, at medium opacity. For the control group of all groups, 12 specimens were photopolymerized by each LED A and B without the interposition of the ceramic disc. A significant difference was observed between all cements studied (p < 0.05). Photoactivated resin cements had the highest GC compared to dual resin cements, with VARIOLINK-LC having the highest GC (51.58 ± 3.82%) and RELYX-ULT having the lowest GC (26.75 ± 2.99%). Regarding the influence of the light-curing light on the GC, for the cements studied, mainly for the cements Rely X Ultimate, Rely The most significant GC values were presented by light-activated resin cements when photopolymerized by Valo Grand Cordless.
