[Assessment of superficial roughness of 3 composite resins treated with different polishing techniques]

In this study, the superficial roughness of two composite resins classified as condensable and of a traditional hybrid composite resin was analyzed after different polishing techniques. Test specimens were confected, immersed in distilled water for 24 hours and submitted to two different techniques of superficial treatment, in which disc systems (Sof-Lex and Super Snap) and silicon tips (Enhance) were utilized. The results revealed the greater superficial roughness of Alert, when compared with Solitaire and Degufill Mineral--no statistically significant differences were observed between the last two materials. The superficial roughness of the specimens polished with Enhance tips was greater than that of the specimens polished with discs and there were no statistically significant differences between both disc systems.
