title: Bleaching of a discoloured non-vital tooth: use of a sodium perborate/water paste as the bleaching agent.
abstract: Bleaching materials containing hydrogen peroxide have been used successfully for the treatment of discoloured non-vital teeth; however, their use has occasionally been associated with external root resorption. Some evidence exists that sodium perborate mixed with water is as effective as sodium perborate mixed with hydrogen peroxide. A case is presented which supports this and a step-by-step technique is described.
