Apical Closure of Nonvital Permanent Teeth: 15 Months Follow-up Study of Four Cases
نویسندگان
چکیده
Obtaining a complete seal of the root canal system is a major problem in performing root canal treatment in nonvital teeth with incomplete root development and wide open apices. The aim was to study apexification using mineral trioxide aggregate (MTA), clinically and radiographically over a period of 15 months. MTA was used in four cases of teeth with incomplete root development in order to achieve an apical seal and the remaining canal was obturated with gutta-percha. Clinical and radiographic assessments of teeth were done. The clinical and radiographic results indicated that apexification procedure was predictable by using MTA. The total number of patients' visits and the total time duration required to obtain an apical barrier using MTA was markedly less than that of conventional techniques using calcium hydroxide.

Re: Efficacy of revascularization to induce apexification/apexogensis in infected, nonvital, immature teeth: a pilot clinical study.
Endodontic treatment options for immature, nonvital teeth conventionally include surgical endodontics, apexification with calcium hydroxide, or single visit mineral trioxide aggregate plug. A new treatment option of revascularization has recently been introduced. It involves disinfecting the root canal system, providing a matrix of blood clot into which cells could grow, and sealing of the coro...

Both molars were found to have immature roots. ,4 nonvital molar was treated to achieve apical closure followed later by conventional endodontic therapy. A vital molar was treated with a formocresol pulpotomy followed by conventional endodontic therapy. After 10 years, both molars sh...

This report presents the case of a 10-year-old patient with a nonvital young permanent tooth which was managed by pulp revascularization. Following disinfection of the canal by irrigation with NaOCl and use of a triantibiotic paste, a scaffold was created by inducing the formation of a blood clot within the canal. At the subsequent follow-up visits, the patient was asymptomatic, with normal res...

INTRODUCTION This retrospective cohort study compared clinical and radiographic outcomes of endodontic treatment performed in immature nonvital permanent teeth by apexification (calcium hydroxide or apical barrier with mineral trioxide aggregate) versus revascularization. METHODS A comprehensive chart review was performed to obtain a cohort of previously completed cases with recalls. Clinical...
