Colour Change of Hot Immersed Polymerized Acrylic Resin Steeped into Roselle Tea (Hibiscus sabdariffa) and Black Tea (Camellia sinensis)

Steeping rosella tea and black are effective as denture cleaning agents they contain flavonoids that can inhibit the growth of C. Albicans. Flavonoids in brewing found pigment compounds, so when acrylic resin is soaked steeping roselle tea, it cause discoloration.This study aims to compare color changes with same treatment. A total 18 samples were divided into three groups; six immersed 20% concentrated concentration mineral water for 22 hours 30 minutes at room temperature. The research results' data analyzed using one-way Anova test. Acrylic experienced a change, largest change occurred tea. results showed hot polymerized had greater than
