Effect of effervescent multivitamin solutions on the color stability of contemporary resin composites: an in vitro study.

Researchers immersed five resin composites in solutions containing three different effervescent multivitamin tablets or distilled water for 28 days and measured color changes. Two composites—Filtek One Bulk Fill and Omnichroma—showed clinically unacceptable discoloration when exposed to certain vitamin solutions, with Filtek One Bulk Fill affected most severely.
