Intracoronal bleaching is currently disregarded by many clinicians because of the potential consequence of cervical resorption. To prevent this complication it is recommended that intra coronal barrier materials be placed over the root canal obturation and sodium perborate be used with water rather than with hydrogen peroxide. The purpose of this study was to evaluate the amount of the hydrogen peroxide penetration according to the difference in intracanal base materials and sodium perborate preparation. Fifty extracted intact premolars were instrumented, and filled with gutta-percha. And then the outer surface of the teeth was sealed with wax exposing the CEJ. The prepared teeth were placed in plastic tubes containing 1.5ml distilled water with their entire root submerged into the solution, The teeth were divided into the following five groups. In the first two groups gutta-percha was removed without placement of barrier, and then water or superoxole(30%
