The final stages of the restoration procedure are finishing and polishing. The finishing procedure need to be done properly to produce optimum contour and restoration results. This study was conducted to determine the surface roughness value of nanofiller composite using Arkansas stone and fine diamond bur. Methods: This study is quasi experimental. Thirty two cylinders of nanofiller resin based composite samples (diameter 6 mm and height 3 mm) were prepared. Those samples were divided into two groups. First sixteen samples were finished by Arkansas stone, the other sixteen were finished by fine diamond bur. Surface roughness was measured using Surface Roughness Tester. T-Test Independent was conducted to depict the data analysis. Result: The average surface roughness value of finished Arkansas stone is 0.59 μm and fine diamond bur 0.77 μm. The result of this study shows statistically significant. It was found surface roughness finished by fine diamond bur was rougher than Arkansas stone. Conclusion: This study showed that statistically significant on surface roughness value of finishing nanofiller composite restoration between Arkansas stone with fine diamond bur.
