<jats:title>Material and Methods:</jats:title>
<jats:p>Ninety-six composite resin disks were randomly divided into four groups, one of which was the control group. The surface roughness and microhardness values were measured after 24 h in the polishing process. The samples were divided into three subgroups and kept in distilled water, cola, and ice tea for 20 min a day for 14 days. Then, the roughness and microhardness measurements of the samples were taken again. Two samples randomly selected from each group were examined using a scanning electron microscope (SEM) and analyzed statistically using the two way anova (ANOVA) and Duncan tests.</jats:p>

<jats:title>Results:</jats:title>
<jats:p>A statistically significant difference was found between the roughness and hardness values at the end of 24 h and 14 days. Onegloss (OG), Dentoflex (DF), and Super-snap (SNP) polish systems showed the highest roughness in the cola group, respectively. Microhardness values: The unpolished group had the lowest significant microhardness in the coke group (<jats:italic toggle="yes">P</jats:italic> &lt; 0.05).</jats:p>

<jats:title>Conclusion:</jats:title>
<jats:p>In this study, it was seen that the lowest success rate was the OG polishing system.</jats:p>
