X‐ray diffraction analysis of mineral trioxide aggregate and Portland cement

Abstract

The four cements had similar major constituents. Data on Portland cement may be used for the further development or modification of ProRoot MTA in order to improve its physical characteristics and expand its scope of clinical applications.

An in vitro evaluation of the antibacterial properties of three mineral trioxide aggregate (MTA) against five oral bacteria

“…All the three MTA materials tested inhibited the growth of caries-associated bacteria, with MTA-Angelus having the greatest effect, followed by ProRoot MTA, and finally Endocem MTA. Despite the fact that ProRoot MTA was also very effective in inhibiting the growth of caries-associated bacteria, either MTA-Angelus or Endocem MTA seem to be the materials of choice for pulp capping in one-visit deep caries treatment, because the shorter setting time of MTA-Angelus (14 (Santos, Araujo, Yukimitu, Barbosa, & Moraes, 2008)-15 min (Angelus, 2015)) and Endocem MTA (4 (Choi et al, 2013)-15 min (Kim, Yang, Kim, & Ko, 2014)) compared to that of ProRoot MTA (140 (Islam, Chng, & Yap, 2006)-318 min (Kim et al, 2014)) enables the placement of permanent restoration in a single visit. This would not only save chair time but also help minimize possible contamination of the cavity, which may occur during the temporization period in a conventional two-visit treatment wherein a permanent restoration is placed over the set MTA in the next visit.…”

Monoblocks in Root Canals: A Hypothetical or a Tangible Goal

“…2). MTA is composed principally of Portland cement with the addition of bismuth trioxide to render it radiopaque (29,30). Being an entirely inorganic material, Portland cement undergoes chemical shrinkage following hydration.…”

The Influence of Calcium Chloride on the Setting Time, Solubility, Disintegration, and pH of Mineral Trioxide Aggregate and White Portland Cement with a Radiopacifier

“…Conversely, white MTA (Angelus Soluçõ es Odontoló gicas, Londrina, PR, Brazil) contains 80% Portland cement clinker and 20% bismuth oxide (8). Both MTA and Portland cement are composed of the same substances (9). Fourteen of 15 chemical elements analyzed were identical (10).…”
