    Abstract

    Aim: This study aimed to evaluate the color stability of nanohybrid direct resin-based composites and indirect resin-based composites to Indian spices. Materials and methods: Fifty samples of the nanohybrid resin-based composite (G-aenial) and the indirect resin-based composite (Adoro) were prepared using an acrylic template of dimension 8 mm × 3 mm. All the samples were polished with the Sof-Lex polishing kit. They were randomly divided into five groups and immersed in solutions of turmeric powder, tamarind extract, paprika powder, and saffron extract. Artificial saliva was used as the control group. Color values (L*a*b*) were measured by a reflectance spectrophotometer using the Commission Internationale de l'Eclairage (CIE) L*a*b* system before and after 24 hours, 48 hours, 72 hours, and 1 month of immersion. Color differences ΔE*ab were statistically analyzed by the two-way repeated measures ANOVA and the post hoc Tukey test using IBM SPSS v19.0. Results: The results exhibited statistical significance between all five solutions and two groups at each time point considered (p < 0.05). From the mean, it is evident that in both indirect and direct composite groups, turmeric solution is having the highest mean when compared to other four solutions. Conclusion: Indirect resin-based composites (Adoro) show less stainability when compared to direct resin-based composites (G-aenial). In both groups, turmeric showed maximum discoloration. Clinical significance: Both the direct and indirect composites have a tendency to get stained with Indian spices. Indirect composites stain lesser to Indian spices when compared to direct composites. Thus, indirect composites are recommended for esthetic restorations.
