SURGICAL REMOVAL OF SUPERNUMERARY TOOTH FOLLOWED BY ORTHODONTIC TRACTION OF PERMANENT CENTRAL INCISOR BY FIXED APPLIANCE THERAPY

Management of immature root with a necrotic pulp and apical periodontitis is a challenging task. Obturation of the root canal is difficult because of lack of apical barrier for containing the root filling material. Treatment of choice in such cases is the apexification procedure, i.e., establishing an apical barrier. Calcium hydroxide has been widely used for the induction of hard tissue barrier. However, this material requires 5-20 months to form the hard tissue barrier. It has also been shown that the use of calcium hydroxide weakens the resistance of the dentin to fracture. In recent times, mineral trioxide aggregate (MTA) has gained widespread popularity for the apexification procedure. It produces apical hard tissue formation with significantly greater consistency than calcium hydroxide.MTA, a biocompatible material, can be used to create a physical barrier. It also helps in the formation of bone and periodontium around its interface
