Recently, regeneration of immature necrotic pulp has become an alternative conservative treatment option for young permanent teeth and is a subject of great interest in the field of endodontics. The primary goal of these procedures is to activate the potential of the pulp for dentine deposition and produce a stronger mature root that withstands the forces better. However, the current protocol has potential clinical and biological complications. Amongst them, crown discoloration caused by triple antibiotic paste is deemed to be very frustrating for the dentist and the patient. In the case presented, there was a successful reversal of the crown discoloration by an internal bleaching procedure with superoxol at follow up periods of 3, 6 and 12 months. However, further long-term clinical trials and histological studies are needed to evaluate the long-term outcomes of walking bleach with superoxol in regenerative endodontic procedures.
