MTA for Obturation of Mandibular Central Incisors with Open Apices: Case Report

Abstract

The case reported demonstrates dramatic healing of the periapical region of retreated root canals with open apices by the successful use of mineral trioxide aggregate (MTA). Unsuccessful conventional root canal therapy for the mandibular central incisors had been followed by surgical treatment. The severely damaged root canals were obturated using MTA in anticipation of the formation of artificial apical plugs. The treated teeth were asymptomatic, and radiographic examination demonstrated apparent regeneration of periradicular tissue 2 years after the obturation. MTA can be considered a very effective material to promote regeneration of apical tissue, even in teeth with large open apices.

Apical barrier technique using MTA: report of two cases

“…(6) MTA has shown good sealing abilities and biocompatibility to the periradicular tissue. (7,8,9) MTA has been successfully used as an apical barrier. (10,11) In this case maintaining sterilization of root canal, intracanal medicament, good apical seal using MTA and a three dimensional obturation has contributed to the success of the cases.…”

Comparison of Compressive Strength and Setting Time of Four Experimental Nanohybrid Mineral Trioxide Aggregates and Angelus Mineral Trioxide Aggregate

“…Nowadays, these materials have a variety of applications, such as closing perforations on pulp chamber floor, 1 repairing furcation perforations 2 and creating apical barrier, 3 coating material after pulpotomy in permanent teeth 4 and primary teeth, 5 filling the roots of primary teeth 6 and undeveloped permanent teeth 7 and developed teeth, 8 apexification of undeveloped teeth with necrosis pulp, 9 and sealer on the tooth root. 10 Improving MTA's mechanical and physical properties will be among the priorities, given the sensitivity of using MTA, especially in maintaining pulp vitality and creation of apical barrier.…”

Comparison of root canal filling quality by mineral trioxide aggregate and gutta percha cones/AH plus sealer

“…Recently, mineral trioxide aggregate (MTA) was evaluated as an orthograde canal-filling material 6,7) . MTA was introduced by Torabinejad and his group in the 1990s 8) .…”
