Abstract :Aim: To assess the effect of three different polishing protocols on the surface roughness and color change of the enamel and compare the results with the enamel specimens exposed to coffee. Methods: Seventy-two bovine enamel specimens were randomly divided into two groups-Group I:only polishing,Group II:immersion in coffee solution and polishing–which were then subdivided into 3 groups according to polishing procedures as follows:polishing with rubber cup and Pumice Flourinsert ignore into journalissuearticles values(PF);,polishing with rubber cup and Prophy Pasteinsert ignore into journalissuearticles values(PP);,polishing with Air Abrasioninsert ignore into journalissuearticles values(AA);. Surface roughnessinsert ignore into journalissuearticles values(Ra); and tooth color were assessed using a surface profilometer and a digital spectrophotometer. The color change was determined by the CIE L*a*b* system. SEM analysis were also performed. Statistical analyses were performed by GraphPad software. Multiple comparisons between-groups and in-groups were performed using Kruskal-Wallis and Friedman tests, respectively. Results: At baseline measurements, no significant differences were found among groups in terms of roughness and color valuesinsert ignore into journalissuearticles values(p>0.05);. In Group I,surface roughness values and color change were similar after polishing insert ignore into journalissuearticles values(p:0.393,p:0.093, respectively);. In Group II,post-polishing Ra values were significantly increased in all groupsinsert ignore into journalissuearticles values(p0.05); and the highest ΔE value was detected in PP group. Conclusion: Following coffee immersion, enamel surfaces become rougher in all polishing protocols and the roughest surface was in PF group. In all study groups visible clinical success was achieved in terms of color, therefore dental clinicians should prefer PP in clinical practice due to the less abrasive and sufficient color change properties.
