MTA
Also written as: MTA — Mineral Trioxide Aggregate
Abbreviation for Mineral Trioxide Aggregate; a biocompatible cement used in dentistry for pulp capping, pulpotomy, and root-end filling procedures.
Full Definition
Mineral Trioxide Aggregate (MTA) is a calcium silicate-based material valued in endodontics and paediatric dentistry for its biocompatibility, antimicrobial properties, and ability to set in the presence of moisture. It is used as a pulp-capping agent, a pulpotomy medicament, a root-end filling material in apicectomy, and for the repair of root perforations. Editors should ensure MTA is expanded on first use, as the abbreviation is not universally known outside specialist clinical audiences.
Usage
Usage note: MTA should be expanded to 'Mineral Trioxide Aggregate (MTA)' on first use. It is a proprietary concept now used generically; brand names such as ProRoot MTA should be distinguished from the generic material class in clinical and academic writing.
