Aim: This study aims to measure the flowable composite restorative of shade A3.5, "Dentsply Sirona-Spectra ST flow," for surface roughness both before and after polymerization and storage in various media. Materials and Methods: Four discs of Dentsply Sirona-Spectra ST flow restorative composite in shade A3.5 have been prepared and cured under visible light. These discs are now immersed in a total of four different solutions for 7 days, and the pre- and post-immersion surface roughness is noted. Results: From the current study, the mean values and the standard deviation of the mean (Ra) values of the surface roughness of the resin composite discs after 7 days resulted in almost a decrease in Ra in all groups except for group 4 (turmeric water), which increased the surface roughness after 7 days. Thus leading to the need for the replacement of the restoration. Conclusion: Based on the values provided by the stylus profilometer, it shows that turmeric water caused the surface roughness to be extremely high, followed by orange juice. Milk and water made almost no difference. Despite having the best physical and chemical properties, the nanofilled resin composite's surface roughness appears to have an impact on how long the restoration would persist and also on the esthetic properties of the resin composite restoration.
