Abstract
In restorative dentistry, selection of materials is decisive to obtain optimal aesthetic results, in the case of dental resins, the size characteristics and particle distribution of the different polishing systems, constitute a factor considerably influences the results. Objective: The purpose of the present research work was to compare three systems employed to polishing composite resin, documenting the results at the microscopic level, to identifying which of them showed better results concerning the roughness. Material and methods: Three polishing systems were evaluated: Soflex from 3M®, Optra Pol and Astrobrush from Ivoclar® Vivadent and Jiffy Hishine from Ultradent, employing the LSM 700 Confocal Microscopy System, also roughness was observed and registered on the surface of a nanofiller resin Tetric Evoceram Ivoclar® Vivadent inserted in stainless steel molds. Results: The roughness mean observed were as follows: 13.95μm for Soflex of 3M®, 13.45μm for Optra Pol of Ivoclar® and 8.05μm for Jiffy Hishine Ultradent. All data recorded in Microsoft Excel 2010 IBM STATISTICS, determinated statistical differences between the groups of Ultradent®. Conclusion: The lowest roughness corresponded to Ultradent with values of 8.01μm.
