The color change effect of children's beverages on preheated polyacid-modified composite resins

Aim Color stability is crucial to the esthetic success of restorative materials. The research carried out on the development of restorative materials, especially the preheating process to resins draws attention due to some advantages. The purpose of the research was to examine the effect of preheated polyacid-modified composite resins of children's beverages on color stability in vitro. Materials and methods The discs were prepared from A2-colored polyacid-modified composite resin material preheated at four different temperatures (4, 23, 39, and 55°C). The discs were kept in distilled water, cola, cherry juice, and chocolate milk. The data obtained by calculating the color changes were statistically evaluated using a two-way robust analysis of variance. Results No significant color change was observed in the chocolate milk group compared to the distilled water group at all preheating temperatures on the working period. In the cola group, a similar color change was observed for up to 60 days at pretemperature values of 39 and 55°C, and up to 30 days at temperatures of 4 and 23°C. Conclusion It should be considered that the preheating process may be beneficial for the longevity of the color stability of restorations, and that different beverage groups may have different effects.
