Newer Technique of Extra-Coronal Bleaching with Sodium Perborate on Non-Pitted Fluorosis Stains in Permanent Anterior Teeth.

Abstract

To evaluate the esthetic improvement of non-pitted fluorosis stains using sodium perborate and compare with etch bleach seal, microabrasion and in-office bleaching with 30% H2O2 on visual assessment scale VAS (primary objective) and to assess any untoward effects including staining, sensitivity, gingival problems within the course of study (secondary objectives). A randomized control trial with 6 months follow up. Methodology- Twenty children aged 8 to 12 years with non-pitted fluorosis in upper anterior teeth were divided into 4 groups with 5 patients in each group. All of the techniques showed improvement in esthetics with VAS. However, microabrasion and bleaching using sodium perborate had significantly better results than other 2 techniques. Sodium perborate showed excellent results in extracoronal bleaching of fluorosed teeth. However a randomized study with large sample size is required to draw a definitive conclusion regarding superiority of one technique over others.
