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.

Hydration mechanisms of mineral trioxide aggregate

International Endodontic Journal, 2007
AbstractAim  To report the hydration mechanism of white mineral trioxide aggregate (White MTA, Dentsply, Tulsa Dental Products, Tulsa, OK, USA).Methodology  The chemical constitution of white MTA was studied by viewing the powder in polished sections under the scanning electron microscope (SEM). The hydration of both white MTA and white Portland cement

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.

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.
