Title Of Article :
THE EFFECT OF FINISHING AND POLISHING PROCEDURES ON THE SURFACE ROUGHNESS OF DIFFERENT COMPOSITE RESINS
Abstract :
Objective: The aim of this study is to evaluate finishing and polishing the effects of finishing and polishing procedures on the surface roughness of four different composite resins. Material and Method: Majesty Flow (MF), Surefill SDR (SDR), Tetric Flow (TF), Tetric N Ceram (TNC) were used in the study. A total of 40 specimens from 10 for each group by using metal molds (2mm depth and 8 mm diameter) were prepared.The specimens were cured for 20 seconds with LED light curing unit for polymerization. Afterwards the specimens were stored in an incubator for 24 hours. After this period the surface roughness were measured from three different points with profilometer. Then finishing and polishing procedures were made and the surface roughness were measured again. The corelation between the measured values were stastistically analyzed with Bonferroni and Mann-Whitney-U tests. Results: TF showed statistically higher surface roughness values when compared with other tested materials before polishing procedures. SDR showed statistically higher surface roughness values when compared with other tested materials after polishing procedures. Conclusion: Recently developed flowable composite resin restorative materials have comparable surface specifications with traditional conventional resins.
