  • Title: Composite surfaces after finishing and polishing techniques.
    Author: Turssi CP, Saad JR, Duarte SL, Rodrigues AL.
    Journal: Am J Dent; 2000 Jun; 13(3):136-8. PubMed ID: 11763949.
    Abstract:
    PURPOSE: To evaluate the effect of finishing and polishing techniques on surface roughness of resin-based composites (RBCs). MATERIALS AND METHODS: Forty specimens of each material were cured under Mylar strips and immersed in artificial saliva for 1 wk. Samples were tested with a profilometer to obtain baseline average surface roughness (Ra). Specimens of both RBCs were then finished and polished according to four techniques: (1) Sof-Lex disks; (2) Sof-Lex disks followed by Prisma Gloss; (3) Enhance points; (4) Enhance points followed by Prisma Gloss application. New readings of the roughness pattern were carried out and the difference of post-polishing and baseline values were analyzed. RESULTS: ANOVA test (alpha = 0.05) did not show differences between materials (P = 0.9393) nor interaction effects (P = 0.3094), but significant difference among the finishing/polishing techniques were detected (P = 0.0157). Tukey's test showed that the smoothest surface was obtained when the specimens were treated by Sof-Lex followed by Prisma Gloss polishing paste; and the worst results were obtained after using Enhance points alone.
