To evaluate the surface roughness and staining of a glass ionomer cement when subjected to different finishing procedures.
Sixty-four discs of Chem-Fil II glass ionomer cement were submitted to staining test with methylene blue by spectrophotometry and roughness test by profilometry. Four groups were evaluated: Mylar matrix (control). Sof-Lex discs, Enhance points, and diamond bur.
Staining and roughness test, analyzed by ANOVA and Tukey's test, showed that the best surface was obtained when the material cured in contact with the Mylar matrix strip or when treated with Sof-Lex discs. The poorest results were obtained after using the diamond bur.
评估玻璃离子水门汀在经过不同的修整程序时的表面粗糙度和染色情况。
采用分光光度法对64片Chem-Fil II玻璃离子水门汀圆盘进行亚甲蓝染色试验，采用轮廓仪进行粗糙度试验。评估了四组：聚酯薄膜基质（对照）、Sof-Lex圆盘、Enhance尖和金刚砂车针。
通过方差分析和Tukey检验分析染色和粗糙度试验，结果表明，当材料与聚酯薄膜基质条接触固化或用Sof-Lex圆盘处理时，可获得最佳表面。使用金刚砂车针后得到的结果最差。
