Effects of bioflavonoid-containing mouth rinses on optical properties of tooth-coloured dental restorative materials.

This study investigated differences in colour (ΔE) and translucency parameter (ΔTP) of nanofilled/microhybrid composites and a glass-ionomer cement following immersion in bioflavonoid (Citrox)- or chlorhexidine-based mouth rinses. Sixty disc-shaped specimens (N = 5/group) of Filtek Supreme (3M), Gradia Anterior (GC) and Fuji IX (GC) were exposed to Citrox/0.2%CHX (Perio+0.
