Abstract
The discoloration of permanent teeth has a significant aesthetic and social impact. Treatment options for discolored non-vital teeth are restoration, bleaching, crowns, laminate and veneers. However, the method for preparation of crown or veneer has a significant disadvantage as an invasive technique. The intervention should include minimal damage to the tooth structure and should not affect future restoration options. Compared with dental crowns, the advantage of bleaching is that it provides a simple conservative method that can remove stains and whiten discolored teeth without destroying the tooth structure. This article presents a case report of combined (internal and external) bleaching techniques for non-vital discolored teeth, which can be considered as a clinically effective method that is beneficial to patients and clinicians. It needs a periodic evaluation to obtain good functionality and aesthetics.
