Abstract
|
|
|
|
Mineral Trioxide Aggregate (MTA) has been successfully used for root end filling, perforation repair, pulp capping and treatment of teeth with open apex. This clinical success of MTA is based on its superior biocompatibility and dental hard tissue forming ability. Portland cement has similar chemical composition with Proroot MTA. However, heavy metal content in Proroot MTA and Portland cement showed difference. Recently, alternatives for Proroot MTA, such as MTA angelus, Bioaggregate, and Ortho MTA was developed and introduced in dental market. Future studies on biological behaviors and mechanical characteristics of these various MTAs are needed.
