Abstract
Preserving the vitality of traumatically injured and mechanically exposed immature teeth is one of the major treatment aims in endodontics. Conventionally, calcium hydroxide (CH) materials have long been used as the agents of choice for vital pulp therapy. But, in recent years, Mineral trioxide ggregate (MTA) is considered to be a reliable material for use in vital pulp therapy in dental traumatology and may replace CH. On the basis of various experimental results, it is proved as a biocompatible material with a high sealing ability and has been used for various purposes in endodontics, including root end filling, sealing of perforations, treatment of teeth with open apices, an as a pulp capping agent.
Despite of its many advantages, MTA has some drawbacks. One of the main drawbacks of MTA is a discoloration potential. Because of discoloration problem after the use of originally developed MTA (GMTA), the manufacturer introduced a new formula of MTA with an off-white color (WMTA); however, several studies have reported tooth discoloration after using both kinds of MTA. This effect limits MTA application in treatment of perforations, pulp capping, pulpotomy, and as an apical barrier in esthetically sensitive areas. Although the incidence of tooth discoloration induced by MTA is frequent, there have been few published reports addressing this issue. This presentation will address the recent reports and our findings on the tooth discoloration after the use of MTA.
