Summary:	Objective: This study aimed to evaluate the bristle splaying and abrasive potential on enamel and resin composite of different toothbrushes after simulated brushing. Methods: Seventy bovine teeth were embedded in polystyrene resin and had a circular cavity on buccal flat surface restored with resin composite (Forma, Ultradent) and were submitted to a simulated brushing (n = 10) with 7 toothbrushes: ColorCare (Bianco Oral Care); DeliCare (Bianco Oral Care); Carbon-Magnetic (Bianco Oral Care); SlimSoft (Colgate Palmolive Company); Pro Cuidado (Colgate Palmolive Company); Curaprox 5460 (Curaden International AG) , and Curaprox 3960 (Curaden International AG). Brushing simulation was performed for 30, 90 and 180 days. At baseline and after 30, 90 and 180 days, the enamel and resin composite surface roughness (Ra, μm) were evaluated using a profilometer with 5 measurements performed on enamel and resin composite (n = 10). Wear index and wear rate were evaluated using macrophotographs and scanning electron microscopy (SEM) at 8x, 25x and 100x. Two-way RM ANOVA was performed for Ra and wear index followed by Tukey’s test. Wear rate were analyzed using Kruskal Wallis and Duns tests. All tests employed α=0.05. Results: Ra of resin composite significantly increased after 30 days with SlimSoft, after 90 days with SlimSoft, Pro Cuidado and Carbon, and after 180 days Colgate Pro Cuidado and CS3960 resulted in higher Ra (P <0.001). Ra of enamel significantly increased on all 3 moments. After 30 days no difference was observed on Ra of enamel among toothbrush, after 90 days Pro Cuidado resulted in higher Ra and after 180 days, Pro Cuidado and Carbon resulted in higher enamel Ra. CS5460 and Carbon presented the highest wear index differences. Wear rate was lower when macrophotographs were analyzed compared with SEM images. With 180 days SlimSoft and CS5460 presented higher wear rate. Conclusion: Toothbrushes with more bristles and smaller diameter of filaments like CS5460, Carbon and SlimSoft showed a higher wear rate and wear index. The surface roughness at 180 days was higher with brushes with fewer bristles and larger filament diameters, Procuidado and CS3960 in composite resin and higher with Procuidado in enamel.
