Abstract
Aim: Mineral Trioxide Aggregate (MTA) is widely used in clinical application such as pulp capping, perforation repair, root-end sealing, canal filling at internal and external root resorption and pulpotomies in primary and permanent teeth. In endodontic field when using a material such as MTA the interaction between material and periapical tissue is so important for healing and life time of endodontic therapy. Although it is sealing ability, the interaction with cells or tissues and their replay to this material play major role for endodontic success. Methods: Literature review was performed using electronic and hand-searching methods for the clinical applications, experimental studies and cellular studies of MTA between 2000 and 2010. Results: MTA is a bioactive material when using vital pulpotomies, apical barrier formation for necrotic pulps and open apices. Numerous study and case reports show MTA is more effective material than other materials in these cases. Many studies have shown the effects of MTA on cementoblasts and odontoblasts. Conclusion: This review shows its composition, biologic action when used different endodontic procedure and interaction between cell and tissues
