Abstract
Aim: In pediatric dentistry, where fast finishing processes are of great importance to reduce the roughness in order to obtain an ideal restoration surface. In restorative materials, differences in surface roughness may occur with the pre-heating process. Therefore, the aim of the study is to compare the surface roughness of the compomer prepared at four different temperatures.
 Materials and Methods: In this study, discs prepared from light-cured compomer prepared at four different temperatures were evaluated and their surface roughnesses were compared. Compomer, which was brought to pre-heat values using a composite heating device to bring it to 39 ºC and 55 ºC, was placed on silicone discs with a diameter of 10 mm and a thickness of 2 mm. The surface roughness was measured with a profilometer device. Statistical analysis was performed with One Way ANOVA and t-test.
 Results: The surface roughness value of the compomer was the highest at 4 °C and the lowest at 55 °C. A statistically significant difference was found between the roughness value of compomer at 4 °C and the roughness values at 23 °C and 55 °C (p
