Use MTA in Your Endodontic cases [Simplified Guide] , Many Dentists have written a lot about MTA and there are tons of theory in the books and internet for you. Ill not provide with notes of MTA. So why read this post ? Read this post because ill tell you about clinical application of this material - How to use MTA? Where to use MTA ? How to Manipulate MTA. Advantages and Disadvantages of MTA. MTA stands for Mineral Trioxide Aggregate.It was 1993 when Torabinejad first introduced MTA in dental field. Technically its nothing but a super fine and modified "Portland cement" what we find in hardware stores. Endodontics need precision and care, Miscalculation of 1mm can increased the chances of failure. Composition- Tricalcium Silicate Tricalcium aluminate Tricalcium Oxide Silicate Oxide Bismuth Oxide- radio opaque Small amount of other mineral oxideOn hydration of this powder it forms colloidal gel, on solidification this mass forms a impermiable barrier. After solidification it reaches to pH of 12.5 which is similar to CaoH. Clinical application-Cases of Root perforation-Its healing results are remarkable.Root End feeling material in open apex.
