EVALUATION OF COLOR STABILITY OF CEROMERS AT DIFFERENT SOLUTIONS

Restorative composites containing glass and quartz particles in the resin matrix, single-tooth restorations or prosthetic material used as veneer restorations. according to this new fiber reinforced composite materials to strengthen the structure of composites (frc) and ceramics reinforced composite (ceromer) to be divided into two main groups. this study ceromer coloring material different solutions, was carried out to evaluate the properties and color stability. in our study 5 mm diameter and 4 mm high ceromer cylindrical specimens were obtained. the samples were divided into five groups. eight samples for each group were randomly selected. color values of the prepared samples were recorded immediately. then samples of each group were separately immersed in various solution (solution 1: 990 ml saliva, solution 2: 660 ml saliva + 330ml tea, solution 3: 660 ml saliva + 330 ml coffee, solution 4: 660 ml saliva + 330 ml cola, solution 5: 660 ml saliva + 330 ml fruit juice). samples were immersed in solution 7, 15 and 30 days. color values were measured and recorded. color values are widely used for color analysis were determined by cie color analysis system. analysis of variance was used to evaluate the data. different of drinks and waiting time was significantly higher (p <0.001) were statistically significant.
