To evaluate the effects of different beverages on the surface roughness of different resin composites.

Materials and methods

A total number of 80 discs (5´2 mm dimensions) were made from (Filtek One bulk fill, x-tra fil bulk fill, REVEAL HD, and Filtek Z350XT) and polished. Each group was divided into 4 subgroups, subgroup 1 was immersed in artificial saliva, subgroup 2 was immersed in beer, subgroup 3 was immersed in red bull, and subgroup 4 was immersed in grape juice (n=5). The specimens were immersed in a protocol of 15 min 3 times a day for 30 days. The baseline data (before immersion) and after immersion of surface roughness measurements were recorded with a surface profilometer. The collected data were statistically analyzed using Two-way and One-way analysis of variance (ANOVA) and then Paired t-test (p ≤0.001).


Beverages have on significant effect on most of RCs surface roughness. The high mean of change occurred in Filtek one bulk fill group immersed in beer (1.808±0.606) and the low in Filtek Z350XT immersed in grape juice (0.74±0.29).


Different beverages affected the surface roughness of Bulk fill resin composites (Filtek one BF, Xtra BF, REVEAL HD BF) but beer is the only beverage that affects bulk fill and conventional Filtek Z350XT.
