Describes a treatment alternative that promises esthetic improvement with minimal complications.
- Root Canal Therapy performed on anterior tooth and the gutta percha was removed 2-3mm apical to cervicolabial level. Walking bleach paste was mixed and placed in canal. 35% superoxyl (H2O2) and sodium perborate powder. The paste was covered with a cotton pellet soaked in superoxyl and closed with cavit and replaced every 2-5 days until esthetics achieved. Final access was restored with composite resin.
- After 18 months the bleach shade remained the same for the tetracycline stained teeth
- Found the predentine zone to be the center for high concentrations of stain impossible to bleach by external methods
