MTA
Also written as: MTA — Mineral Trioxide Aggregate
Mineral Trioxide Aggregate — a biocompatible calcium silicate-based dental cement used in pulp capping, perforation repair, and root-end filling procedures.
Full Definition
MTA (Mineral Trioxide Aggregate) is a hydraulic calcium silicate cement widely used in endodontics and pediatric dentistry for its superior biocompatibility, sealing ability, and capacity to set in the presence of moisture. Clinical indications include direct pulp capping, pulpotomy, apexification, perforation repair, and retrograde root-end fillings. It appears frequently in endodontic case reports, operative notes, and material specification sections of research articles. Editors should always expand the acronym on first use and verify consistent capitalisation.
Usage
Usage note: Expand on first mention; avoid confusion with non-dental uses of the same acronym.
