Abstract:
The purpose of this study was to verify the polymerization efficiency of two curing units through a ceramic barrier. Forty specimens apiece of two resin luting cements (AllCem and RelyX U100) were made in a stainless steel mold. The experimental group was photocured through a ceramic barrier, while the control group was photocured without a barrier. The specimens were stored in deionized water or 75% ethanol for 28 days and submitted to tests of sorption and solubility (ISO 4049:2000). Values obtained were subjected to ANOVA and Tukey multiple comparison tests (P < 0.05). RelyX U100 suffered more sorption and solubility than AllCem. The light sources did not influence sorption and solubility values, except for the specimens of RelyX U100 that were photocured with an LED unit through ceramic and stored in ethanol; these specimens demonstrated higher values than those photocured using a halogen lamp.
