An innovative chairside bleaching protocol for treating stained dentition: initial results.Pract Periodontics Aesthet Dent. 2000 Sep; 12(7):669-76; quiz 678.PP
For years, investigators have attempted to develop a predictable means of bleaching pathologically and nonpathologically stained dentition. While previous efforts have modified the concentration of the bleaching material, the duration of the procedure, and the manner by which the bleaching agent is activated, the ability to affect a significant shade improvement remains an elusive objective. This article demonstrates an innovative technique used to influence the penetration of oxygen ions into the tooth enamel, which may resolve this clinical dilemma.
