Pulpal necrosis is one of the main complications of dental trauma which implies an interruption of the root maturation and the apical closure of an immature tooth. Apexification is a therapy used for inducing the creation of an apical calcified barrier allowing a permanent filling of the root. Several materials have been recommended to induce apexification and preserve aesthetics in teeth with immature apex, such as mineral trioxide aggregate (MTA), calcium hydroxide [Ca (OH)2], glass fiber posts, as well as the different materials used in prosthetic dentistry, ceramics that reproduce the appearance of the natural dentition and show an optic behavior very similar to the hard tissues of the teeth. This case reports a 17 year old male patient with a complicated crown fracture, exposed root canal in the oral cavity with incomplete root formation. The purpose of this clinical case is to describe the use of apexification as the first choice to keep a useful tooth, using the formation of an apical barrier with mineral trioxide aggregate (MTA) and recover the patient aesthetics. Conclusions: The appropriate intracanal medication for inducing the formation of an apical closure in an immature tooth or with an incomplete root formation, is of vital importance for the success of the process of apexification where MTA plays an important role due to the fact that right now is the material that gives more advantages in this particular practice as an inducer in that process.
