Abstrakt: Background: This study aims to investigate the effects of different staining solutions on the color stability of hybrid composites and nanohybrid composites. Materials and Methods: One hundred and ten composite resin samples were made in disc shape and divided into two groups, comprising 55 samples each of hybrid composite samples and nanohybrid composite samples. Both the groups were further divided into experimental group of fifty samples and control group of five samples. Hybrid experimental group and nanohybrid experimental group were again divided into five subgroups according to immersion medium, namely coffee, tea, coke, turmeric, and red wine. Each subgroup was comprised of ten samples. Both the control group samples were immersed separately into distilled water. Solutions were changed daily. Color measurements were obtained using spectrophotometer on the 1st, 7th, and 30th days. For statistical evaluation, analysis of variance and Tukey's tests were used at a significance level of 0.05. Results: Color change of materials in staining agents ranked in this increasing order: water < cola < tea < coffee < turmeric < red wine. Nanohybrid composite resin showed lesser perceptible color changes in comparison to hybrid composite. Conclusions: The tested hybrid composite resins were more susceptible to discoloration in comparison to nanohybrid composite resins. [ABSTRACT FROM AUTHOR]
