A CLINICAL STUDY OF MINERAL TRIOXIDE AGGREGATE(MAT) AS A ROOT END FILLING MATERIAL

Abstract
|
|
|
Although numerous materials have been recommended as root end filling material, so far no material has been found to satisfy all of the requirements of an ideal material. An experimental material, mineral trioxide aggregate( MTA ), has been recently developed to seal off all pathways of communication between the root canal system and the external surface of the tooth. This material has been used to seal the root end cavities in exuacted teeth and similar preparations in beagle dogs and shown very premising results.
In this clinical study,5 anterior teeth from three patients were used to clinically and radiographically evaluate the efficacy of MTA as a root end filling material on a short-term basis. After removing the apical 2 to 3 mm of the roots, The root end cavities were prepared and filled with MTA.
The results were as follows:
1. All the cases demonstrated excellent healing radiographically and absence of clinical signs and symptoms.
2. According to the results, it appeared that MTA had a good sealing ability and biocompatibility.
3. MTA showed very promising results as a root end filling material, but Long-term clinical retrospective studies of many cases are recommended to get the most valid evaluations.
