Abstract

Discoloration of composite resins is considered to be a major factor in esthetic restoration failures. The aim of this study was to evaluate COLOR STABILITY of IDM composite (both light and SELF CURE samples namely IL and IS), and to compare it with a self-cure composite (Degufill named DS) and a LIGHT CURE ormocer composite (Definite, called DL in the Report). 60 disk shaped samples of each composite were prepared, according to ISO-7491. The samples were divided into 3 groups and aged as follows: A- (Control) 7 days in dark 37 c chamber B- Foil covered and kept in 100% humidity, and 370 c in XENOTEST chamber for 24 hours, then transferred to a dark 370 c chamber for 6 more days.C- Kept in 370 c, 100% humidity under the emission of xenon lamp of XENOTEST chamber for 24 hours, and then transferred to 370 c dark chamber for 6 more days.The lightness and chromaticity values of samples were measured both before and after aging using a SPECTROPHOTOMETER (Data Flash). The total color changes as well as changes in lightness and chromaticity values were measured in the CIE L * a * b * scale, and analyzed. Color change was recorded to be significant in all samples after aging. The maximum change belonged to IL, which was significantly different from DL and DS. It seems, in order to have a durable esthetic restoration using IDM, more scientific and professional consideration is needed in the production process.
