Abstract
Tooth discoloration involves intracoronal or extracoronal color changes on the teeth. Chemical bleaching agents have side effects, and strawberry leaves have ellagic acid, which acts as a natural bleaching agent. Several color space systems are used to measure colors. To determine the bleaching effect of an infusion extract of strawberry leaves and to determine the most suitable color space system on enamel-bleached surfaces. Methods: This is an in vitro study. Infusion extracts of strawberry leaves were applied to three teeth discolored with tea. Infusion extracts of strawberry with a concentration of 15% were applied to the first specimen and a concentration of 30% applied to the second specimen 28 times; multilevel concentrations of 15% to 30% were applied to the third specimen 14 times for each concentration. The analysis was performed using a color space system using image processing software by Adobe Photoshop. The infusion extracts of strawberry leaves made the enamel surface darker. Infusion extracts of strawberry leaves cannot bleach teeth that have discoloration, and the most suitable color space to measure enamel-bleached surfaces is the RGB color space system.
