Abstract
AbstractThe objective of this study was to assess the finished surfaces of various dental composite resin restorative materials using common rotating abrasive devices and diamond and iron‐carbide dental burs. The “finished” surfaces were compared with surfaces created by a polyester matrix band. The “finished” composite resin materials were also compared with filled resins as well as the unfilled polymethyl methacrylate resin. Evaluation of the various finishing procedures was made from scanning electron micrographs. Results indicated that “finished” resins, both filled and composite, departed greatly from an acceptable polished surface and that the use of any resin filled with glass rods would be contraindicated.
