Resumo: Objective: To determine the effect of the restorative technique, material’s opacity and the selected lightsources on the curing potential (CP) in deep cavities. Material and Methods: The radiant exitance (mW/cm2)of two light curing units (Bluephase G2 and Radii-Cal) was determined at 0 and 8 mm distance from a powermeter sensor (Ophir). Two bulk-fill composites of regular consistency (Opus, FGM; and Filtek One, 3M) and aconventional one (Sirius-Z, DFL) were considered and the level of their opacity were determined by a spherebasedspectrophotometer (SP60, X-Rite). The degree of C=C conversion (DC) was determined by spectroscopy(FTIR-ATR) at 0.05 and 8 mm depths and the CP considered the ratio between them. The “incremental technique”considered 4 increments of 2mm thickness each, whereas the “bulk-fill technique considered 2 increments of4mm-thickness. Data were submitted to analysis of variance and Tukey’s test (95%). Pearson’s correlation testswere performed to calculate the possible relation between curing potential and materials’ opacity. Results: Withthe incremental technique it was possible to achieve high CP regardless of the light source. The CP of bulk-fillcomposites was dependent on the light source, whereas Radii-Cal compromised the DC at 8 mm for both materials.The correlation between opacity and CP was dependent on the light source (r = 0.891707246 for Radii-Cal; r =0.515703768 for Bluephase G2). Conclusion: The bulk-fill technique was dependent on the light source whilethe incremental was not. The influence of materials’ opacity was dependent on the light curing unit.KEYWORDSConversion; Opacity; Resins; Light curing.
