Abstract

Background and Objective: The COLORED COMPOMERs are a group of restorative materials that are introduced for filling of primary dentition since 2002. These materials have been used in pediatric dentistry because of their attractive colors and their simple handling properties. But their characteristics have not been evaluated and compared completely. Since a change in the color of these materials can change its physical characteristics, the aim of this study was evaluation of COLORED COMPOMER MICRO-HARDNESS in 20, 40 and 60 second time curing.Materials and Methods: In this in vitro study, 180 composite discs were prepared. Then, each color (blue, green, lemon, golden, silver and pink) was packed into the discs, and was cured for 20, 40 and 60 s. Specimens were stored for 10 days in an incubator with distilled water at 37oC and away from direct light. Then, surface MICRO-HARDNESS measurements were carried out using a Vickers MICRO-HARDNESS tester in three different points on the top and bottom surface of each sample.Results: Silver color had maximum MICRO-HARDNESS value (44.19), and blue color had minimum MICRO-HARDNESS value (39.52). Green, golden, pink and lemon had average MICRO-HARDNESS values (42). Statistical analysis shows that compomer color and side of specimen had significant influence on compomer MICRO-HARDNESS. However, no significant influence in various time of curing on compomer MICRO-HARDNESS was found out. A comparison between colors showed that blue color had minimum MICRO-HARDNESS and silver color had maximum MICRO-HARDNESS (p<0.05).Conclusion: Based on the results of this study, the color of compomer influences MICRO-HARDNESS. Due to maximum MICRO-HARDNESS of two colors, i.e. silver and lemon, these are recommended for restoration of primary dentition.
