However, there is no evidence determining whether this staining is increased on texturized surfaces or if the color change is superficial and can be removed by repolishing procedures. Objective:  To evaluate the effect of tobacco smoke on the color of a composite with smooth or texturized surfaces, before and after repolishing. Materials and Methods:  Forty composite specimens were allocated into four groups (N = 10): Smooth surface not exposed (G1) and exposed to tobacco smoke (G2), texturized surface not exposed (G3), and exposed to tobacco smoke (G4). During 21 days, G2 and G4 were daily exposed to the smoke from 20 cigarettes. Color measurements were carried out at baseline, after 21 days, and after repolishing. Variables L* (luminosity), b* (blue-yellow), and ΔE (total color change) were statistically analyzed (repeated measures analysis of variance/Tukey). Results:  Texturized and smooth specimens presented similar luminosity at baseline. Tobacco smoke significantly reduced L* in G2 and G4, and increased b* in G4. After repolishing, L* increased and b* reduced in stained groups, but values continued to be different from baseline ones. Repolishing significantly reduced ΔE, but values from stained groups were still greater than that from unstained groups. Conclusion:  Tobacco smoke changes the color of composite, and surface texture can increase the staining. Repolishing reduces superficial staining, but this procedure may not return the composite to baseline color.Submitted by Suelen Reis (suziy.ellen@gmail.com) on 2013-08-23T14:11:30Z No. of bitstreams: 1 j.1708-8240.2010.00347.x.pdf: 311240 bytes, checksum: f45dddcaaf8837f67708aabb21fc8adc (MD5)Approved for entry into archive by Flávia Ferreira (flaviaccf@yahoo.com.br) on 2013-11-06T20:32:11Z (GMT) No. of bitstreams: 1 j.1708-8240.2010.00347.x.pdf: 311240 bytes, checksum: f45dddcaaf8837f67708aabb21fc8adc (MD5)Made available in DSpace on 2013-11-06T20:32:11Z (GMT).
