Evaluation of surface roughness of resin veneers finished and polished by different techniques

ABSTRACT

Four different resin veneers and composite resins were evaluated for surface roughness after finishing and polishing. The resins were prepared against celluloid strip and finished then polished by four different methods imitating the clinical methods. The surface roughness of these resins was evaluated using surface profile tester. The results of this study showed resin veneers prepared against celluloid strip has the highly polished surface. Finishing and polishing veneers in the oral cavity should be done using white flexible disk or rubber abrasive point with polishing gel to get highly polished surface comparable to that obtained using celluloid strip
