CASE SUMMARY
A 16-year-old patient presented with a nonvital maxillary central incisor with an open apex, secondary to trauma. Due to the lack of apical closure, traditional root canal obturation was not feasible. Apexification was chosen as the treatment modality to induce the formation of a calcified apical barrier, allowing for proper root canal sealing. Historically, calcium hydroxide was the material of choice for apexification, requiring multiple visits and prolonged treatment duration. However, the introduction of bioceramic materials such as MTA has revolutionized the procedure, offering superior outcomes with reduced treatment time.
In this case, the apexification procedure involved thorough canal disinfection using NaOCl, enhanced by internal heating, ultrasonic activation, and double-sided vented needle irrigation. Under the dental operating microscope, MTA was precisely placed at the apex using a MAP system, ensuring a dense, void-free apical barrier. The remaining canal space was subsequently sealed with a bioceramic sealer to promote long-term stability and healing.
