Apexification of traumatized anterior teeth with blunderbuss canals using MTA putty and collagen membrane: A case report

INTRODUCTION. Trauma to developing permanent teeth can disrupt root formation, leading to open apices and weakened tooth structure. AIM. This report details the non-surgical management of an 8-year-old male with blunderbuss canals in anterior teeth using mineral trioxide aggregate (MTA) putty and a resorbable collagen membrane to support apical barrier formation and healing. MATERIALS AND METHODS. Non-surgical apexification was performed using MTA putty as the primary apical barrier material, supplemented by a resorbable collagen membrane to aid in barrier formation and periapical healing. RESULTS. Over 12 months, clinical and radiographic follow-ups showed successful healing with no periapical pathology.
