Clinical applications of mineral trioxide aggregate

Journal of Endodontics, 1999
An experimental material, mineral trioxide aggregate (MTA), has recently been investigated as a potential alternative restorative material to the presently used materials in endodontics. Several in vitro and in vivo studies have shown that MTA prevents microleakage, is biocompatible, and promotes regeneration of the original tissues when it is placed ...

Cellular response to mineral trioxide aggregate

Journal of Endodontics, 1998
This investigation studied the cytomorphology of osteoblasts in the presence of Mineral Trioxide Aggregate (MTA) and examined cytokine production. MTA and Intermediate Restorative Material (IRM) were prepared and placed in separate Petri dishes. Osteoblasts (cell-line MG-63), grown to confluence in Hams F12/Dulbecco's modified Eagle's medium, were ...

Color stability of white mineral trioxide aggregate

Clinical Oral Investigations, 2012
This study aims to evaluate the color stability of white mineral trioxide aggregate (WMTA) after irradiation with three different curing lights and with a fluorescent lamp in an oxygen-free environment.Thirty samples of WMTA were divided into four experimental groups (three curing light and one fluorescent lamp) and one negative control group.

Vital pulp therapy with mineral trioxide aggregate

Dental Traumatology, 2005
Abstract –  The present case report describes the treatment of complicated crown fractures using mineral trioxide aggregate (MTA). MTA was used as pulp‐capping material after partial pulpotomy to preserve the vitality of the pulpal tissues in two cases.

Mineral Trioxide Aggregate Inhibits Osteoclastic Bone Resorption

Journal of Dental Research, 2011
Mineral trioxide aggregate (MTA), a commonly used endodontic repair material, is useful for both basic and clinical research, and the effect of MTA on osteoblast differentiation has been well-defined. However, the effects of MTA on osteoclastic bone resorption are not fully understood.

Introduction to Mineral Trioxide Aggregate

2014
Mineral trioxide aggregate (MTA) is a are powder primarily composed of tri- and dicalcium silicates with bismuth oxide radiopacifier. MTA has been an addition to the dental armamentarium since the 1990s. When mixed with water, MTA powder forms hard cement by hydration of the silicates.

Coronal Tooth Discoloration and White Mineral Trioxide Aggregate

Journal of Endodontics, 2013
This study assessed and characterized discoloration when white MTA (wMTA) was placed in the coronal aspect of the root canal ex vivo and the influence of red blood cells on this discoloration.Canals were prepared from the apical aspect and restored with either wMTA + saline (n = 18), wMTA + blood (n = 18), or controls (n = 4 + 4) (blood or saline alone)

Mineral Trioxide Aggregate Repair of Lateral Root Perforations

Journal of Endodontics, 2001
This study was conducted to observe the healing process of intentional lateral root perforation repaired with mineral trioxide aggregate (MTA). Forty-eight root canals of dogs' teeth were instrumented and filled. After partial removal of the filling, an intentional perforation was made with a bur in the lateral area of the root.

Biocompatibility of mineral trioxide aggregate flow and biodentine

International Endodontic Journal, 2018
AbstractAimTo evaluate the influence of powder‐to‐gel ratio (0.19 g powder to 50 μL of gel, thick MTA Flow, and 0.06 g powder to 50 μL of gel, fluid MTA Flow) on biocompatibility of MTA Flow (Ultradent Products Inc., South Jordan, UT, USA, lot: 2015122901) and compare it with Biodentine (Septodont Inc., Saint‐Maur‐des‐Fossés, France, lot: B18542A ...

Properties of Hydrated Mineral Trioxide Aggregate

2014
Mineral trioxide aggregate (MTA) is composed of Portland cement and bismuth oxide as radiopacifying material. This chapter aimed at discussing the physicochemical and biological properties of MTA. When MTA is mixed with water, it hydrates to form a solid structure after 2–3 h.
