Resumo
The aim of this study was to evaluate different Light Cure Unit (LCU) and polishing protocols on surface roughness and gloss of a composite resin. Roughness and gloss of samples (n=8) of nanohybrid composite resin (E1, VOCO Cuxhaven, Hamburg, Germany) were evaluated and lightcured with different light-emitting diode (LED) devices: Valo (Ultradent, Salt Lake City, Utah, USA), Valo Grand (Ultradent, Salt Lake City, Utah, USA), Bluephase 20i (Ivoclar, Schaan, Liechtenstein), Elipar DeepCure-L (3M ESPE, St Paul, MN, USA), Emitter D (Schuster, Hyannis, MA, USA) and Radii Xpert (SDI Bayswater, Survey, Australia); and polished with three different systems: Sof-Lex Diamond Polishing System (3M ESPE, St Paul, MN, USA), Jiffy Original Composite System (Ultradent, Salt Lake City, Utah, USA) and Opti1Step (Kerr, Orange, CA, USA). There was no difference for the different LEDs for roughness (P=0.935) and gloss (P=0.012). For the superficial roughness test Sof-Lex and Opti1Step were similar between themselves and significantly superior to Jiffy. For the gloss test Sof-Lex and Opti1Step presented superior results than Jiffy. The LCU did not influence the roughness and gloss of the composite resin, while the polishing protocol showed influence on the result.
