![]() When in contact with moisture, it’s main component, which is calcium oxide, converts into calcium hydroxide which many clinicians will be familiar with. Unlike many other dental materials, MTA sets in a moist environment. A stable barrier to bacterial and fluid leakage is one of the key factors which facilitates clinical success.Ī very practical advantage of MTA is that it sets in the moist environment omnipresent in dentistry. 4, 5 The seal achieved is due to its expansion and contraction properties being very similar to dentin which results in high resistance to marginal leakage and to bacterial migration into the root canal system. ![]() This has been observed histologically with the formation of new cementum in periradicular tissues area and a low inflammatory response with bridge formation in the pulp space. High biocompatibility encourages optimal healing responses. The most important of these properties in dentistry are its biocompatibility and sealing ability. MTA has several desirable properties in terms of its biocompatiblity, bioactivity, hydrophilicity, radiopacity, sealing ability and low solubility. 1– 3 The trioxide aggregate in MTA consists of calcium, aluminum and selenium. Over the past two decades, MTA has become one of the most widely studied endodontic materials. MTA stands for Mineral Trioxide Aggregate. ![]()
