| Abstract | ||
| Objectives: to evaluate the color stability in single-shade composite in comparison to multi-shade composite. Methods: 30 discs (n=10) were prepared from 3 different composite materials, two materials (Venus diamond and Charisma Topaz, Heraeus Kulzer) and (3MTM FiltekTM Supreme) was fabricated using a Teflon mold. The specimens were immersed in a coffee solution, before immersing each resin-based composite in coffee (to-baseline) (t0), after3 days (t1), after one weeks (t2), and after 2 weeks (t3) in the staining solution, readings were taken. The specimens’ colors were measured using a Reflective spectrophotometer. Results: At all evaluation times, it was found that composite Group 3 [charisma topaz] recorded highest color change mean value followed by composite Group 2 [Venus diamond] mean value while the lowest recorded color change mean value was for Group 1 [3M filtek supreme]. The difference between composite groups was statistically significant as demonstrated by one-way ANOVA test (p < 0.05). Pair-wise Tukey’s post-hoc showed non-significant (p>0.05) difference between Group 1 and Group 2 means values after three days and two weeks. For all composite groups, it was found that two weeks evaluation time recorded highest color change followed by one week evaluation while the lowest recorded color change was after three days evaluation time. Conclusion: There was a difference in color change between the different composite types. Color stability is material and time dependent. | ||
