Mineral trioxide aggregate (MTA) is a biomaterial used for root-end filling, perforation repair, internal and external resorption, vital pulp therapy and apical barrier formation for teeth with necrotic pulps and open apices. Recently MTA based sealers have opened up the horizon for root canal sealers. Sealers based on MTA have been reported to be biocompatible, stimulate mineralization and encourage apatite-like crystalline deposits along the apical- and middle-thirds of canal walls.
Calcium enriched mixture (CEM) cement, Biodentin, Bioaggregate, and EndoSequence Root Repair Material (ERRM) and EndoSequence BC Sealer have been introduced to the market recently. Is there any difference in the indications, clinical applications and success rate of MTA, biodentine and CEM cement in endodontic uses?
Dear Darwn,
CEM, Biodentin..... e.g. Are endodontic sealers properly. Sealers based in MTA mark the different to improved and get better the obturation of canals in situations that ordinary sealers (with their properties) can't be useful.
MTA sealers are better for canals with a lot of bacteria activities prior or during endodontic treatment or teeth that were exposed to infections for a long period of time, periapical radiographic image and need to repairing or regenerate loss bone in periodontal region or apical specifically. That just was a way to take the most of regeratives properties of this material.
I hope it can be help you. Regards and good luck.....
Dear Alain,
Thanks for your explanation. I got information from it.
Best wishes
Dear Darwn,
Biodentine is an evolution of MTA, since they are both tricalcium silicate-based cement, and Biodentine has the advantage to be composed of highly purified tricalcium silicate, and is thought to be free of heavy metals (presented in MTA).
Both of them can be used in multiples clinical applications, such as pulp capping, pulpotomy, lateral root perforation, etc...
Specifically in pulpotomy and pulp capping Biodentine appears to have better results than MTA, which you can see in one paper done in my department (De Rossi A, Silva LA, Gatón-Hernández P, Sousa-Neto MD, Nelson-Filho P, Silva
RA, de Queiroz AM. Comparison of pulpal responses to pulpotomy and pulp capping
with biodentine and mineral trioxide aggregate in dogs. J Endod. 2014
Sep;40(9):1362-9.)
I hope it helps you,
Sorry about my english...
Biodentine have a seting time less than MTA, but the use and indications of this material is the same.
