J Endod 1995;21:349-53. The calcium silicate hydrate may be considered a gel that forms on the calcium silicate particles and hardens with time to form a solid network with the calcium hydroxide nucleated within the pore and void space (Gandolfi, Factors that affect setting: additives and accelerants. The authors concluded that MTA is a biocompatible material that stimulates the repair of the periradicular tissues. Histological and scanning electron microscopy assessment of various vital pulp-therapy materials. The calcium silicate hydrate may be considered a gel that forms on the calcium silicate particles and hardens with time to form a solid network with the calcium hydroxide nucleated within the pore and void space (Gandolfi et al. The MTA compositions include optional radiocontrast and nano-enriched leachable fluorine, nitrate, strontium, and phosphate. This can be used for root-end filling material and as pulp capping material. Fig. 1993) as an aggregate of mineral oxides added to “trioxides” of tricalcium silicate, tricalcium aluminate, and tricalcium oxide silicate oxide. The two versions of mineral trioxide aggregate (MTA; gray and white) have enjoyed clinical success in endodontics since 1995. Kettering JD, Torabinejad M.

It should be used by trained dental clinicians (dentists, dental specialists and dental therapists) with a good understanding the procedures and are qualified to perform such procedures. Furthermore, exposure of the calcium hydroxide to carbon dioxide contained in physiological fluids is expected to convert some of it to calcium carbonate (Chedella & Berzins 2010; Darvell & Wu 2011). It is formulated from commercial Portland cement, combined with bismuth oxide powder for radio-opacity. Mineral trioxide aggregate (MTA) is composed of Portland cement, with 4:1 addition of bismuth oxide added so that the material can be detected on a radiograph. J Endod 1993;19:541-4. 822 MTA Angelus (White): 1 g of White MTA, 3 ml of distilled water, 1 scoop. As mentioned above, comparison to ordinary Portland cement is problematic due to variations in Portland cement commercial products, but using microscopy, Dammaschke and associates observed white MTA powder to have a more uniform and smaller particle size compared with Portland cement powder (Fig. With some exceptions, MTA materials provide better microleakage The Portland cement component in MTA consists of tricalcium silicate (3CaO ∙ SiO2 or Ca3SiO5, also known as alite), dicalcium silicate (2CaO ∙SiO2 or Ca2SiO4, also known as belite), and tricalcium aluminate (3CaO ∙ Al2O3 or Ca3Al2O6). In a typical Portland cement powder, tricalcium silicate and dicalcium silicate are in greatest proportion and are estimated to be roughly 75–80% of the cement, with tricalcium aluminate and tetracalcium aluminoferrite at approximately 10% each (Ramachandran et al. Next, the mixture is ground and blended together and introduced into a rotary, cylindrical kiln where it is heated to 1430−1650 ºC. 2010b; Darvell & Wu 2011). Mineral trioxide aggregate (MTA) is a unique material with several exciting clinical applications. Mineral Trioxide Aggregate (MTA) is a dental material used in vital pulp therapy and some endodontic procedures. J Endod 1995;21:603-8. In present article, we review the current dental literature on MTA, discussing composition, physical, chemical and biological properties and clinical characteristics of MTA. Asgary S, Parirokh M, Egbbal MJ, Brink F. Chemical differences between white and gray mineral trioxide aggregate. The commercial product was first available as a gray variety, and a tooth-colored version commonly referred to as “white MTA” was introduced in 2002 (. 2.3). MTA COMPOSITION. Additionally, magnesium (or a magnesium oxide form) is also frequently observed in greater proportion in gray MTA than in white MTA (Song et al. 2008; Comin-Chiaramonti et al. 2005; Song et al. J Endod 2003;29:324-33. ENDOCEM MTA is a revolutionary next generation, fast-setting, MTA (Mineral Trioxide Aggregate) product that is pozzolan-based.

J Endod 2001;27:7-8. Int Endod J 2004;37:325-36. The MTA composition support remineralization and biomineralization, and it is suitable for stimulation of hard tissue regeneration. Several researchers have noted the absence of iron in white MTA in contrast to its presence in gray MTA (Camilleri et al. Evaluation of setting properties and retention characteristics of Mineral Trioxide Aggregate when used as a furcation perforation repair material. O'Sullivan SM, Hartwell GR. Sluyk SR, Moon PC, Hartwell GR. • Bismuth oxide (20%). MTA is a mixture of Portland cement and bismuth oxide, which is added to enhance the radiopacity of the material. Mineral trioxide aggregate in paediatric dentistry. Some conflicting reports exist as to whether it is truly calcium sulfate dihydrate in MTA, with other possibilities being calcium sulfate hemihydrate (CaSO4 ∙ ½H2O) or the anhydrous form (CaSO4) (Camilleri 2007, 2008; Belío-Reyes et al. Source: Lee et al. 2.4) (Dammaschke et al. While some of these elements would generally be of concern from a toxicological point of view, given their low concentration in MTA and MTA’s excellent biocompatibility, they likely have no impact on health. The two most important hydration reactions are those of the greatest constituents, tricalcium silicate and dicalcium silicate. ABSTRACT: Mineral Trioxide Aggregate (MTA)* is a special purpose dental material developed at Loma Linda University.Studies to evaluate its properties and explore possible applications have yielded promising results. In 1997, Tulsa Dental Products (now Dentsply Tulsa Dental Specialties) received a decision from the US Food and Drug Administration (FDA) that MTA was substantially equivalent in intended use and technological characteristics to similar products on the market for repairing pulpal tissues. Composition of MTA MTA is a mechanical mixture of 3 powder ingredients: • Portland cement (75%). 2.1 Gray and tooth-colored ProRoot MTA. Mineral trioxide aggregate (MTA) was invented in the mid-1990s at Loma Linda University, USA, with the aim of introducing a material for use as a root-end filler that would set and develop its properties in the presence of moisture. MTA is generally mentioned as a dental material of great value for cases of non-favorable prognosis for parendodontic surgery and reportedly increases the success rates of any other procedures in which it is used (8,9). 2019; 20(23): 5960, © Journal of Oral Research and Review | Published by Wolters Kluwer -, Perforation repair - Apical, lateral, furcation, Resorption repair - External and internal, Repair of fracture - Horizontal and Vertical, Apical barrier for tooth with necrotic pulps and open apex, Coronal barrier for regenerative endodontics. Shah PM, Chong BS, Sidhu SK, Pitt Ford TR. The Material Safety Data Sheet (MSDS) of ProRoot MTA states that it is approximately 75 wt% Portland cement, 20 wt% bismuth oxide (Bi 2 O 3), and 5 wt% calcium sulfate dihydrate or gypsum (CaSO 4 ∙ 2H 2 O). The hydration reactions of the two minor components of Portland cement are influenced by gypsum. J Endod 2006;32:1094-6. It is a new remarkable biocompatiblematerial with exciting clinical applications pioneered by Dr. Mahmoud Torabinejad, Loma Linda University, in 1993. J Endod 1995;21:537-42. 2003). General Dental Sciences, Marquette University, USA. 2004. Between MTA products, it appears the particles are more homogeneously sized in white MTA compared with gray MTA (Komabayashi & Spångberg 2008) and have fewer larger particles (Camilleri et al. 2005, 2006). Torabinejad M, Chivian N. Clinical applications of mineral trioxide aggregate. Dent Traumatol 2012;28:33-41. Radio opacity of potential root end filling materials. Sumer M, Muglali M, Bodrumlu E, Guvenic T. Reactions of connective tissue to amalgam, intermediate restorative material, mineral trioxide aggregate mixed with chlorhexidine. Regardless, it appears that the addition of bismuth oxide to Portland cement decreases its compressive strength and increases porosity (Coomaraswamy, The principal products are calcium silicate hydrates and calcium hydroxide (also known as Portlandite). Administration.2 MTA is commercially available as a ProRoot MTA (Tulsa Dental Products, Tulsa, OK). Longitudinal sealing ability of mineral trioxide aggregate as a root-end filling material. Once the clinker cools, it is ground to a fine powder size and is now considered Portland cement. MTA is a biocompatible and bioactive material which gained rapid acceptance in the field of dentistry. Since the first research reports, further studies, numbering in the hundreds, were conducted on the initial experimental cement and the commercial ProRoot MTA products (as well as individual constituents and/or similar products). Originally, MTA was dark gray in color, but white versions 2009; Gandolfi et al. 2003; Dammaschke et al. However, others debate this (Darvell & Wu 2011). The cement is made up of calcium, silicon and aluminium. The effect of condensation pressure on selected physical properties of mineral trioxide aggregate.
