Walking bleach with sodium perborate tetrahydrate: A safer material and method

Abstract

In the era of minimum invasive dentistry and increased demand of esthetics, intra-coronal bleaching in an intact tooth is the most successful yet conservative method. Nonetheless oxidative materials such as hydrogen peroxide, carbamide peroxide, sodium perborate (monohydrate, trihydrate, tetrahydrate) used in combination or alone mixed with water for the same may create complications such as external root resorption. This case report illustrate the use of a bio-friendly material i.e. sodium perborate tetrahydrate with walking bleach technique.
