mta dental composition

During endodontic treatment of primary and permanent tooth MTA can be used in many ways. MTA is a mixture of Portland cement and bismuth oxide, which is added to enhance the radiopacity of the material. 2005). Next, the mixture is ground and blended together and introduced into a rotary, cylindrical kiln where it is heated to 1430−1650 ºC.

It is formulated from commercial Portland cement, combined with bismuth oxide powder for radio-opacity. Mineral trioxide aggregate: A new material for endodontics. J Endod 2003;29:679-82. 2009; Gandolfi et al. However, others debate this (Darvell & Wu 2011). INTRODUCTION Independent analysis suggests that the material of Mineral Trioxide Aggregate (MTA) is identical to Portland cement. 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). Today, it is a very common hydraulic cement due to its inclusion in concrete, stucco, and mortar. Lee SJ, Monsef M, Torabinejad M. Sealing ability of a mineral trioxide aggregate for repair of lateral root perforations. Dent Traumatol 2001;17:163-6. • Tricalcium aluminate. 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). The powder of MTA contains fine hydrophilic particles (1.0-30 µm) of calcium silicate phases and bismuth … Dent Res J 2007;4:83-7. Mineral trioxide aggregate (MTA) was developed at Loma Linda University (Loma Linda, California, USA) and was first described in the dental scientific literature in 1993. Tetracalcium aluminoferrite (4CaO ∙ Al2O3 ∙ Fe2O3), on the other hand, is considered present in gray MTA but not in white MTA. Ease of manipulation as well as the unique ability to stimulate osteogenesis and cementogenesis make this biocompatible material a perfect choice for endodontic repair. ABSTRACT: The aims of Part-1 updated review are present the chemical composition, setting reaction, mechanism of action and physical properties of Mineral Trioxide Aggregate (MTA). Int Endod J 2007;40:453-61. J Endod 1998;24:768-71. ENDOCEM MTA exhibits high efficacy not only in apical retro-filling and root perforations, but also in vital pulp therapies such as direct pulp capping. 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 (Figs 2.1 and 2.2). The effect of condensation pressure on selected physical properties of mineral trioxide aggregate. 2005. Torabinejad M, Hong CU, McDonald F, Pitt Ford TR. This also holds true for white MTA versus gray MTA (Asgary et al. The main constituent phases are tricalcium and dicalcium silicate and tricalcium al … However, MTA has lower amounts of tricalcium aluminate compared with ordinary Portland cement, and it has been determined that the content of Ca3SiO5, Ca2SiO4, Ca3Al2O6, CaSO4, and Bi2O3 in white MTA is 51.9, 23.2, 3.8, 1.3, and 19.8 wt%, respectively (Belío-Reyes et al. Additional minor trace elements may also be present as stated in the MSDS. dental literature. Fig. 2.3). When mixed with water, it forms via an exothermic reaction. The main constituent phases are tricalcium and dicalcium silicate and tricalcium aluminate. This leads to the suggestion that MTA powder is not produced in a kiln but in a laboratory (Camilleri 2007, 2008), although others have said it is manufactured the same way as Portland cement (Darvell & Wu 2011). In the presence of gypsum and water, tricalcium aluminate forms ettringite [Ca6(AlO3)2(SO4)3 ∙ 32H2O] according to the following reaction: The initial patent (United States Patent #5,415,547, continued to #5,769,638) on what would become known as MTA was filed the preceding April by Mahmoud Torabinejad and Dean White, and described the tooth filling material as being comprised of Portland cement. Asgary S, Parirokh M, Egbbal MJ, Brink F. Chemical differences between white and gray mineral trioxide aggregate. - Ref. ENDOCEM MTA is a revolutionary next generation, fast-setting, MTA (Mineral Trioxide Aggregate) product that is pozzolan-based. Shipper G, Grossman ES, Botha AJ, Cleaton-Jones PE. Evaluation of setting properties and retention characteristics of Mineral Trioxide Aggregate when used as a furcation perforation repair material. 2008; Comin-Chiaramonti et al. 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. Abstract and Figures 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. Alternatively, the Portland cement fraction in MTA may also be thought of as mixtures of CaO (lime), SiO2 (silica), and Al2O3 (alumina) – as well as Fe2O3 (iron oxide) for gray MTA. 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). • Gypsum (5%). The ASTM International (formerly the American Society for Testing and Materials) recognizes 10 types of Portland cement (ASTM Standard C150/C150M – 12 2012), but the Portland cement in MTA is restricted to Type I Portland cement. However, others have observed trace amounts of iron in white MTA (Belío-Reyes 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. MTA is a hydraulic type of cement, meaning that it sets by reacting with water, and is then stable in water. 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. 2003): The setting of dicalcium silicate is similarly given by the following reaction (Bhatty 1991; Ramachandran et al. Additionally, magnesium (or a magnesium oxide form) is also frequently observed in greater proportion in gray MTA than in white MTA (Song et al. 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. 2.4 Scanning electron micrograph comparison of (A) Portland cement and (B) MTA powders. 2005, 2006). 1993) as an aggregate of mineral oxides added to “trioxides” of tricalcium silicate, tricalcium aluminate, and tricalcium oxide silicate oxide. - Ref. 2004. MTA is a biocompatible and bioactive material which gained rapid acceptance in the field of dentistry. I WANT IT. 2010). Additional minor trace elements may also be present as stated in the MSDS. Mineral Trioxide Aggregate (MTA) was named in 1998 by Dentsply Tulsa Dental (ProRoot MTA, Dentsply Tulsa Dental, Johnson City, TN, USA) as developed by Dr. Torabinejad. Garcia-Godoy F, Murray PE. 1-3 The chemical composition of MTA was determined by Torabinejad et al. This can be used for root-end filling material and as pulp capping material. - Ref. Sluyk SR, Moon PC, Hartwell GR. Radio opacity of potential root end filling materials. Mineral trioxide aggregate (MTA) was first described in the scientific literature in 1993 (Lee et al. 2005) but greater amounts of bismuth (as Bi2O3 for radiopacity), and, therefore, its Portland cement component is of purer form. • Tricalcium oxide. Several researchers have noted the absence of iron in white MTA in contrast to its presence in gray MTA (Camilleri et al. J Endod 1995;21:537-42. As stated in the patent, MTA is comprised primarily of Portland cement. Although it has been debated in the literature whether a clinician could use Portland cement in place of MTA due to its general similarities, it should be pointed out again that MTA is approved for use in patients by the FDA and is sterilized. Roy CO, Jeansonne BG, Gerrets TF. Mineral trioxide aggregate (MTA) has been a revolutionary material in endodontics. Thus, water is both a reactant and is contained in the reaction products of MTA.

The initial patent (United States Patent #5,415,547, continued to #5,769,638) on what would become known as MTA was filed the preceding April by Mahmoud Torabinejad and Dean White, and described the tooth filling material as being comprised of Portland cement. MTA is used for creating apical plugs during apexification, repairing root perforations during root canal therapy, and treating internal root resorption. With some exceptions, MTA materials provide better microleakage Recently, MTA Angelus (Angelus Solucoes Odonto-logicas, Londrina, Brazil) became available on the mar-ket. In both animal and human studies, MTA materials have been shown to have excellent potential as pulp-capping and pulpotomy medicaments. The two versions of mineral trioxide aggregate (MTA; gray and white) have enjoyed clinical success in endodontics since 1995. 2006). Arens DE, Torabinejad M.

The chemical composition of the materials was determined by energy‐dispersive X‐ray (EDX), and eluates were analysed by inductively coupled plasma–mass spectrometry (ICP‐MS). J Endod 2001;27:540-2. MTA is a material that exceeds many other materials for endodontic purpose, however, there is a lack of educational material on how to use the material. 2003). Torabinejad M, Chivian N. Clinical applications of mineral trioxide aggregate. Regardless, it appears that the addition of bismuth oxide to Portland cement decreases its compressive strength and increases porosity (Coomaraswamy et al. 2009). Schwartz RS, Mauger M, Clement DJ, Walker WA 3rd. Comparative investigation of marginal adaptation of Mineral Trioxide aggregate and other commonly used root-end filling materials. 5. 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. In terms of shape, many of the particles are rather irregular, with some appearing needle-like (Camilleri et al. MTA has potential and one of the most versatile materials of this century in the field of dentistry. Nandini S, Ballal S, Kandaswamy D.

Dominguez MS, Witherspoon DE, Gutmann JL, Opperman LA. Torabinejad M, Smith PW, Kettering JD, Pitt Ford TR. Although generally considered insoluble in water, speculation exists that it is not totally inert and plays a limited role in the setting of MTA as some bismuth oxide has been shown to form part of the calcium silicate hydrate structure (described below) and leach out over time (Camilleri 2007, 2008). MTA materials are derived from a Portland cement parent compound and have been demonstrated to be biocompatible endodontic repair materials, with its biocom-patible nature strongly suggested by its ability to form hydroxyappatite when exposed to physiologic solutions.

The Material Safety Data Sheet (MSDS) of ProRoot MTA states that it is approximately 75 wt% Portland cement, 20 wt% bismuth oxide (Bi2O3), and 5 wt% calcium sulfate dihydrate or gypsum (CaSO4 ∙ 2H2O). Less of the latter component is contained in white MTA versus gray MTA, but it is still present (Asgary et al. generally considered insoluble in water, speculation exists that it is not totally inert and plays a limited role in the setting of MTA as some bismuth oxide has been shown to form part of the calcium silicate hydrate structure (described below) and leach out over time (Camilleri 2007, 2008). The MTA compositions include optional radiocontrast and nano-enriched leachable fluorine, nitrate, strontium, and phosphate. J Am Dent Assoc 1999;130:967-75. THE DENTAL ADVISOR Online, the place to go when you are searching for in-depth information regarding dental products, manufacturers, industry news and research. 2009). Despite some differences between the experimental and commercial materials, except when noted, no delineation will be made in this chapter between the varieties of MTA. 2005; Song et al. The grayness of GMTA arises from the presence of an iron-containing compound, tetracalcium-aluminoferrite (4CaO-Al 2 O 3 -Fe 2 O 3) in Portland cement (ProRoot ® MTA product literature). Dent Traumatol 2012;28:33-41. The composition of MTA includes : • Tricalcium silicate. 2005), but few differences have been noted as to the shape of particles between MTA and Portland cement (Komabayashi & Spångberg 2008). It mixes more smoothly, is easier to dispense and has more stable placement, washout resistance and faster clinical setting. Other elements and compounds observed in MTA have been: As, Ba, Cd, Cl, Cr, Cu, Ga, In, K, Li, Mn, Mo, Ni, P2O5, Pb, Sr, TiO2, Tl, V, and Zn (Funteas et al. 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.

While many dentists are hesitant to perform direct pulp capping procedures due to previously unpredictable results with conventional materials, MTA is a more predictable and reliable material for direct pulp capping teeth, with reversible pulpitis, as borne out by numerous clinical and histological studies.15-19 Mente et al recently concluded “MTA appears to be more effective than … MTA material can be used as apical and furcation restorative materials as well as medicaments for apexogenesis and apexification treatments. At this point, the mixture is called clinker. While the calcium hydroxide is mostly crystalline and able to be detected using X-ray diffraction (XRD; Camilleri 2008), the calcium silicate hydrates are primarily amorphous and may exhibit a range of compositions. With its designation as a Class II medical device for root canal filling from the FDA, MTA was subsequently marketed as ProRoot MTA. … 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.

J Endod 1995;21:295-9. processes among different cement producers is to be expected; therefore, interpretation of research reports that compare MTA to Portland cement should be mindful of this. The amount of calcium hydroxide produced in MTA has been found to be approximately 10–15% of the hydrated material (Camilleri 2008; Chedella & Berzins 2010), which is below that expected for Portland cement (20–25%; Ramachandran et al. 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. 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. 2003). who compared the composition of Biodentine and MTA Angelus with experimentally produced laboratory cement consisting of tricalcium silicate and zirconium oxide.

Antibacterial effects of some root end filling materials. The size and shape of the powder fraction of MTA has been examined by several researchers (Fig. Similar results were reported by Camilleri et al. Thus, substituting Portland cement for MTA is not advised in clinical procedures. Alternatively, the amounts of CaO, SiO2, Al2O3, and Fe2O3 may be considered to be approximately 50–75, 15–25, <2, and 0–0.5 wt%, respectively (Darvell & Wu 2011). 2011 ) greatest constituents, tricalcium silicate and dicalcium silicate and dicalcium silicate is similarly by!, Clement DJ, Walker WA 3rd a hydraulic type of cement, combined with bismuth oxide for!
