Piyush Gandhi, Simerpreet kaur Bagga, Inderpreet Singh

Background: The smoothness of restorative material’s surfaces has a great importance in the success and clinical longevity of the restorations. Various techniques of finishing and polishing have been proposed and analyzed over time. Hence; the present study was conducted for assessing the efficacy of Finishing and Polishing on the Surface Roughness of Nanofilled Composite. Materials & methods: A total of 120 patients were included in the present study. Only those patients were enrolled in the present study that recently underwent aesthetic restoration of tooth by composite materials. Complete demographic and clinical details of all the patients were obtained. All restorations were divided into 3 groups depending upon finishing and polishing systems as follows: Group A: Shofu finishing and polishing kit, Group B: Sof-Lex composite finishing and polishing kit and Group C: Mylar Strips. All the three study groups contained 40 patients in each group. Then surface sealant (prime & bond) was applied to all treated specimens and the average roughness (Ra) was measured. Results: Mean surface hardness among patients of group A, group B and group C before application of sealant was 0.83, 0.59 and 0.51 respectively. Significant results were obtained while comparing the means surface roughness before application of sealant. Mean surface hardness among patients of group A, group B and group C after application of sealant was 0.71, 0.51 and 0.32 respectively. Significant results were obtained while comparing the means surface roughness after application of sealant. Conclusion: Mylar strip provided the smoothest surfaces followed by Sof-Lex followed by Shofu. Key words: Finishing, Composite, Nanofilled
