A qualitative X-ray analysis of white and grey mineral trioxide aggregate using compositional imaging

Asgary, Saeed; Parirokh, Masoud; Eghbal, Mohammand; Stowe, Sally; Brink, Frank

Description

Mineral trioxide aggregate (MTA) is used in endodontics as a filling and sealant material. An earlier commercial formulation Grey MTA (GMTA) was liable to became progressively discoloured, and a whiter version (WMTA) has been introduced for cosmetic reasons. This study compares the composition and particle size distribution of the two formulations using energy dispersive X-ray analysis in a scanning electron microscope. Particle size is smaller in WMTA. X-ray analysis reveals similar major...[Show more]
