Abstract

Background: Silorane based composite resin has been introduced to esthetic dentistry in the recent past as a solution to overcome the polymerization shrinkage problem of the methacry late based resin composites. Numerous studies have been done on the polymerization shrinkage of Silorane based composite resin, but very few have been done on the long lasting csthctics of this material. Thus a pilot study was done to comparatively evaluate the polishability of the Silorane based resin composites (SBC) with Nano hybrid resin composites (NHC) and Hybrid resin composites (HC). Materials and methods: The surface roughness of Siloranc Based resin composite (Filtck P90, 3M) with nanohybrid resin based composite resin (Tetric N-ceram, lvoclar vivadent) and hybrid resin based composite resin (TE econom plus, Ivoclar vivadent) was assessed using contact profilometer after polishing with composite polishing kit (Shofu Super-Snap mini kit, Shofu Inc.,). The surface structure after polishing was observed under Scanning Electron Microscope. Results: The surface smoothness of SBC and HC compared well whereas the NHC showed rough surface. But no statistically significant difference was present in the surface roughness when measured with contact profilometer. Conclusion: The Silorane based resin composites exhibited polishability similar to hybrid resin based composites.
