Conclusions
Based on the results gained from this study, we concluded that;1- Type of resin composite, and immersion periods have a noticeable effect on color stability and surface roughness of single shade resin composite.2- The single-shade resin composite tested showed "extremely" high perceptibility and acceptability threshold values and surface roughness even with distilled water.3- More studies are needed to dig in-depth into the behavior of such materials.
