364 - Treatment of an Open Apex with an Apical Barrier Using Mineral Trioxide Aggregate

Purpose: Endodontic management of a non-vital, immature teeth with an open apex can be challenging because of the large canals and difficulty obtaining an optimal seal. Mineral Trioxide Aggregate is a material that demonstrates great biocompatibility, marginal adaptation, radiopacity, and low compressive strength. The objective of this case study was to analyze the sealing ability and success of an MTA apical barrier on an immature permanent tooth following trauma.

Methods: A 12-year-old male patient presented to the pediatric dental clinic at the University of Nevada, Las Vegas for a limited exam due to trauma on tooth #7 and #8. An apical barrier was placed with MTA on #8 and root canal treatment was completed.

Results: In this case within one year the clinical and radiographic follow-up revealed the healing of apical lesions and regeneration of the periradicular bone.

Conclusion: This case stresses the importance of utilizing an MTA barrier when treating a tooth that had trauma and pulpal necrosis. An MTA plug is effective because of time management, better fracture resistance, and protection from extrusion of sealer.
