Mineral trioxide aggregate (MTA) was developed more than 20
years ago to seal the pathways of communication of the root canal
system. It's currently the preferred material used by
endodontists because of its superior properties such as its seal
and biocompatibility that significantly improves outcomes of
endodontic treatments.
Dr. Torabinejad, who was the principle investigator of the dental
applications of MTA, and leading authorities on this subject
provide a clinically focused reference detailing the properties and
uses of MTA, including vital pulp therapy (pulp capping,
pulpotomy), apexification, pulp regeneration, repair of root
perforations, root end filling and root canal filling. Line
illustrations and clinical photographs show proper technique. An
accompanying website features photographs and video presentations
for selected procedures using MTA.
Mineral Trioxide Aggregate: Properties and Clinical
Applications is an ideal book for dental students and
endodontic residents learning procedures for the first time as well
as practicing dentists and endodontists who would like to improve
outcomes of endodontic treatments.
