Bulk\u2010fill (Aura, Opus, and Filtek One) and nanofilled (Filtek Z350) composite specimens were submitted to the following: control (CT); bleaching and immersion in distilled water (BL); and bleaching with daily 15\u2010min immersion in coffee (BL\u00a0+\u00a0CF), cola\u2010based drink (BL\u00a0+\u00a0CO), or red wine (BL\u00a0+\u00a0RW) among sessions.
