Evaluation of the effects of finishing and polishing procedures on the surface texture of compomer materials
Fouad S. Salama*, BDS, MS, DABPD, FAAPD
The purpose of this study was to evaluate the effects of finishing and polishing procedures on the surface texture of compomer materials (Dyract and Compoglassl using the Enhance finishing and polishing system, forty-five cylindrical specimens were prepared from each material, fifteen specimens of each material were light cured against a Mylar strip with no finishing or polishing (control), 15 others were finished only using the enhance finishing system (experimental! and another 15 specimens were finished and polished using the Enhance finishing and polishing system (experimental). All specimens were prepared at room temperature and stored for 3 days in closed containers of distilled water (300 ml) in a laboratory oven at 37°C before testing. Both control and experimental specimens of each material were examined and photographed at different magnifications using a stereomicroscope and an SEM. Also, the surface roughness of all specimens was measured with a surface roughness analyzer. The surfaces cured against the Mylar strip demonstrated the smoothest surface. Following the Mylar strip surface, Ihe nexi smoothest surface was seen in finished and polished Dyract followed by finished Compoglass. Finishing and polishing procedures of compomer materials Failed to reproduce the smoothness of surfaces created by mylar strips.
