Abstract
Roselle contains anthocyanins, a group of color pigments. This study determined the effect of immersing 10 bovine teeth in roselle extract solution for 15, 30, 45, and 60 min on enamel discoloration. Color was measured using the VITA Easyshade and CIEL*a*b* color scales. Repeated analysis of variance testing showed significant differences in ΔL*, Δa*, Δb*, and ΔE color values between the control and treatment groups (P < 0.05). Therefore, roselle extract solution may cause enamel discoloration.
