Aim: The aim of this study was to assess the effect of different teas on surface roughness and surface morphology of a conventional resin and three bulk-fill composite resins. Materials and Methods: The three bulk-fill (Beautifil, Tetric N-Ceram, Filtek One) composite resin and one conventional (Z250) composite resin material, three beverages (black tea, kombucha tea, and matcha tea), and distilled water were used. For the surface roughness test (n = 10), 160 samples were prepared, and the initial surface roughness values were measured (t0) with a profilometer device. The final surface roughness evaluation (t1) was made after 12 days of beverage immersions. The surface morphology of samples was evaluated for each group by scanning electron microscope(SEM) and atomic force microscopy(AFM) photomicrographs (n = 3). Ten samples of each composite resin were used for the degree of conversion (DC) analysis. For multiple comparisons, data were analyzed with the independent samples Kruskal–Wallis test, and a one-way analysis of variance test was used to compare DC values with respect to composites (P <.05). Results: There was a statistically significant difference in the kombucha groups between the Beautifil bulk-fill composite and the others (P <.05). Tetric was affected by the kombucha tea (P =.012). The highest DC was obtained from Filtek One; the lowest DC was obtained from the Beautifil (P <.01). In this study, Beautifil showed the highest degree of surface roughness. Conclusions: The acidic beverages affected the surface properties of bulk-fill composite materials negatively in terms of roughness.
