Tooth discoloration is one of the aesthetic problems in dentistry. Tooth discoloration caused by extrinsic factor and intrinsic factor. Thirty five percent Carbamide Peroxide commonly used on office-bleaching that has been approved as a safe and effective bleaching material by American Dental Association (ADA). Strawberry (fragaria x annanassea) is natural materials that can be used as dental bleaching material because it contains ellagic acid. This research aimed to find out the difference of teeth color after immersion strawberry juice and 35% carbamide peroxide. This research was designed using experimental laboratory. The samples were 24 teeth post-extraction, then divided into 2 groups, the first group was treated by immersion in 100% strawberry fruit juice for 30, 60 and 90 minutes. The second group was treated by immersion in 35% peroxide carbamide at the same time. The color of the tooth is measured using a shade guide. The data was analyzed using Kruskal-Wallis test and continued with Mann-Whitney Test. This study shows that the immersion of strawberry juice causes the teeth become brighter. Tooth color changing that already immersed in strawberry juice and carbamide peroxide 35% showed not different significantly at 30, 60 or 90 minute immersion. The conclusion is strawberry juice can be used as an alternative material for dental bleaching.
