Abstract Aim: The aim of this study was to evaluate the effect of brushing with herbal toothpastes on discolored composite resins. Materials and Method: In this in vitro study composite resin materials (Charisma Topaz- Kulzer, Harmonize-Kerr) were polymerized into silicone rubber rings (2mmx10mm) to obtain 60 specimens identical in size. The samples were kept in distilled water for 24 hours then baseline colorimetric evaluation was performed using spectrophotometer (Easy Shade V, Vita). Second colorimetric evaluation was performed after the samples were immersed in coffee (Nescafe Gold, Nestle) for 6 days. 30 discs from each composite group were randomly divided into 3 subgroups of 10 specimens each according to the toothpastes; 1) Control (without toothpaste), 2) Gumgumix (Beka Medicine, Turkey), 3) R.O.C.S Sakura Branch. Last colorimetric evaluation was performed after each sample in each group was brushed for 1 hour using Oral-B Pro 2900 and cross-action head. Data were analysed using Kruskal Wallis, Wilcoxon signed rank and Friedman tests with a significance level of 5%. Results: Statistically significant differences were observed between the colorimetric evaluations (p≤0.05). No difference was found between the herbal toothpastes and control group (p≥0.05). Conclusion: Within the limits of this study, although the herbal toothpastes have been found ineffective on color changing of discolored resin composites, it is concluded that tooth brushing is important on the color stability of composite resin materials.
