Determining the best technique for finishing and polishing composite resins is important to ensure longevity of the restoration and prevention of recurrent decay and periodontal disease. This study quantitatively compared the surface roughness of a small particle hybrid composite material finished and polished using six different techniques. Five composite samples were randomly assigned to one of six polishing techniques. Uniform composite surfaces were prepared by finishing samples with a 600‐grit carborundum disk prior to polishing. The unpolished surfaces were analyzed with the Taylor‐Hobson Talysurf 10 surface texture measuring instrument. The surfaces were then polished and analyzed again. There were no statistical differences among treatment groups prior to polishing. There was a statistical difference between treatment groups after polishing. The smoothest surfaces were obtained using Centrix System rubber points alone, Centrix System rubber points plus Caulk's Prisma Gloss fine and super‐fine pastes, and Caulk's Enhance disks plus Caulk's Prisma Gloss fine and super‐fine pastes. There was no statistical difference between these methods and 3M Sof‐flex disks alone. The roughest surface was produced by the Enhance disks only without using the Prisma Gloss pastes. There was no statistical difference between this method, however, and the use of Sof‐flex disks plus Kerr's Lustre Paste. Lustre Paste, included with Herculite kits, did not improve a surface polished with Sof‐flex disks.
