Color space system analysis of tooth enamel whitening with a phenolic extract of strawberry leaf

Abstract

Teeth discoloration can be treated with dental bleaching but it damages the enamel and gingival tissue. Ellagic acid in strawberry leaf ables to create redox reaction that can whiten teeth. The objective of this study was to determine tooth surface whitening after application with ellagic acid and determine the most appropriate color space system to assess tooth surface color. Strawberry leaf phenolic extract was applied to three teeth with concentration of 15%, 30% and 15% to 30%. Color was analysed using Adobe Photoshop software. Strawberry leaf phenolic extract does not whiten the enamel and the most appropriate color space system is RGB.
