Abstract:

Purpose:The purpose of this study was to assess the colour stability of three different composites under various staining solutions.

Method100 disks (3mm thick and 10mm in diameter) were prepared from three types of composites: (1) Micro hybrid composites (2) Nano composites (3) Hybrid composites. After polishing and obtaining the baseline data, they were equally divided into 4 groups and immersed into 1 of 4 liquids at 37 degree Celsius, (1)Fanta (2) Bournvita (3) Grape Juice (4) Distilled Water. After 1week, 1 month, 2 months they were measured for colour change. Colour difference of each specimen were measured by spectrophotometer.

Result: The datas were compiled, and statistical analysis were performed, using one –way ANOVA and Tukey – HSD procedure at 5%significant level.

Conclusion: The results of the study indicated that Nanocomposite is more stain resistant when compared to other 2 composite resins. Maximum staining was present in Grape juice followed by Bournvita, Fanta, and Distilled Water over an extended period of time
