Clinical Outcomes of Artificial Root-end Barriers with Mineral Trioxide Aggregate in Teeth with Immature Apices

Orthograde Apical Application of an MTA Plug in a Tooth without Constriction - A Case Report

“…Scientific investigations have shown that MTA can release various ions thatconduct and induct hard-tissue formation 4,17 .MTA presents some advantages,including its physical characteristics thatguarantee expansion during the attachment, which favors sealing, and the biological properties ofcalcium hydroxide 3,24 . MTA forms calcium oxide when in contact with water, which then, when in contact with tissue fluids, forms calcium hydroxide and triggers the same repair process in the tissue 11 .Some recentstudies have reported on the success of MTA as a root apical barrier, with rates ranging from 76.5% to 91% 10,20 .…”

Apexification of Immature Teeth Using Novel Apical Matrices and MTA Barrier: Report of Two Cases

“…Recently MTA has also been emerged strongly as artificial rootend closure material in open apices. Both materials were found to stimulate the formation of mineralized tissue, thereby providing an adequate seal in the apical region [17] MTA, a bio-compatible material, can be used to create a physical barrier that also helps in formation of bone and periodontium around its interface [1][2][3][4][5]. Although earlier studies recommended the use of a Ca(OH)2 prior to MTA placement, recent studies report that the initial use of Ca(OH)2 paste was not necessary for apexification to occur, and it has shown to be strongly related to the extrusion of MTA and formation of barriers beyond the limits of the root canal walls.…”

Management of Non-vital Maxillary Central Incisors with Open Apices by MTA Plugging

“…It restricts bacterial infection and establishes a suitable environment for periapical repair. 3 Although calcium hydroxide apexification has a success rates in the mid-90% range 4 , important disadvantages have also been associated with its utilization. The need of multiple appointments, the long period of time for treatment completion, susceptibility to fracture 5 and coronal microleakage during treatment 6 are some of the disadvantages which could be mentioned.…”
