Endodontic treatment, in cases of traumatic teeth with immature apex, requires special care, due to anatomical particularities: Wide root canal, little thickness of dentine walls, absence of apical constriction and apical divergence.
Currently, there are several apexification techniques using calcium hydroxide, MTA or other materials based on calcium silicate, as well as regenerative endodontic treatments.
Female patient, 8 years old, attended the consultation with buccal fistula associated with tooth 11 and also discolored tooth. Parents reported a history of trauma a year and a half ago and dental phobia.
After clinical and radiographic evaluation, it was diagnosed pulp necrosis, chronic apical abscess and incomplete root formation.
Due patient's dental phobia, the suggested treatment was apexification with an MTA apical plug (MAP), in a surgery room.
MTA has a high potential on endodontic treatments due to its sealing capacity, resistance to microleakage and the fact that it can be used in a humid environment or in the presence of blood, making it suitable for use as an apical barrier in teeth with immature apex. Due to this fact, reducing the apexification time for a single session allows definitive restoration to be carried out briefly in order to achieve the coronary resistance, reducing the risk of fracture.
With the presentation of this clinical case, we pretend to highlight the importance of using MTA in apexification due to its high predictability in relation to apical sealing because it allows a reduction in the number of sessions and less dependence on patient compliance.
