Abstract

In children and adolescents, oral and maxillofacial trauma is one of the most common causes of dental and periodontal damage, which often induces crown fracture of the permanent anterior teeth. Frequently, these traumatized teeth lose their vitality, and require routine endodontic treatment if their root apices are closed. However if their apices are not fully closed, further root formation should be promoted by apexification or apexogenesis. Calcium hydroxide is a biocompatible & bacteriostatic material, and is widely used for apexification. However it has several disadvantages which include the need for multiple visits and patient cooperation, low strength and technical sensitivity in a broad apex. In one-visit apexification using IRM or SuperEBA, patient's visits can be minimized. However, their biocompatibility is questionable. Mineral trioxide aggregate(MTA) is a relatively new material. It is considered biocompatible with periapical hard tissue and has good marginal sealing ability. MTA is also known to help facillitate the growth of the cementum around it. In this case report, apexification with MTA was attempted on traumatized maxillary central incisors with immature root apices, and favorable clinical results were achieved.
