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. With some exceptions, MTA materials provide better microleakage J Endod 1999;25:728-30. The hydration reactions of the two minor components of Portland cement are influenced by gypsum. 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). 2010). 2005) but greater amounts of bismuth (as Bi2O3 for radiopacity), and, therefore, its Portland cement component is of purer form. Comparatively, ordinary Portland cement contains approximately double the amount of calcium sulfate species as found in MTA. J Endod 1999;25:197-205. 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. Investigation of mineral trioxide aggregate for root-end-filling in dogs. J Endod 1995;21:349-53. 2.4 Scanning electron micrograph comparison of (A) Portland cement and (B) MTA powders. MTA materials provide better microleakage protection than traditional endodontic repair materials using dye, fluid filtration, and bacterial penetration leakage models. 2005, 2006). 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. Less of the latter component is contained in white MTA versus gray MTA, but it is still present (Asgary et al. Faraco IM Jr, Holland R. Response of the pulp of dogs to capping with mineral trioxide aggregate or a calcium hydroxide cement. The authors concluded that MTA is a biocompatible material that stimulates the repair of the periradicular tissues. Thus, substituting Portland cement for MTA is not advised in clinical procedures. J Endod 2001;27:540-2. In both animal and human studies, MTA materials have been shown to have excellent potential as pulp-capping and pulpotomy medicaments. 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). Bismuth oxide is included in MTA to serve as a radiopaque agent because Portland cement is not sufficiently radiopaque for dental purposes. 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. The cement is made up of calcium, silicon and aluminium. Comparative study of white and grey mineral trioxide aggregate (MTA) simulating a one or two step apical barrier technique. MTA is a hydraulic type of cement, meaning that it sets by reacting with water, and is then stable in water. As would stand to reason, if the initial powder particles in MTA are smaller than those in Portland cement, the particles contained in set (hydrated) MTA are, similarly, smaller than in ordinary Portland cement (Asgary et al. 2005; Song et al. 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.

Additionally, magnesium (or a magnesium oxide form) is also frequently observed in greater proportion in gray MTA than in white MTA (Song et al. Pediatr Dent 2001;23:326-30. Roy CO, Jeansonne BG, Gerrets TF. 2008; Comin-Chiaramonti et al. Fig. This book concisely presents information on diverse aspects of MTA and its use with a view to making it more widely available to clinicians and researchers. 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. Shah PM, Chong BS, Sidhu SK, Pitt Ford TR. 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. … Evaluation of setting properties and retention characteristics of Mineral Trioxide Aggregate when used as a furcation perforation repair material. When mixed with water, it forms via an exothermic reaction.

With its designation as a Class II medical device for root canal filling from the FDA, MTA was subsequently marketed as ProRoot MTA. 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. 2005; Monteiro Bramante et al. The MTA compositions include optional radiocontrast and nano-enriched leachable fluorine, nitrate, strontium, and phosphate. Since its introduction in the 1990s several studies have demonstrated its use in various clinical applications. Holland R, de Souza V, Nery MJ, Otoboni Filho JA, Bernabé PF, Dezan Júnior E. Reaction of dogs' teeth to root canal filling with mineral trioxide aggregate or a glass ionomer sealer. However, others have observed trace amounts of iron in white MTA (Belío-Reyes et al. - Ref.

Sealing ability of a mineral trioxide aggregate for repair of lateral root perforations. I WANT IT. 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 … As stated in the patent, MTA is comprised primarily of Portland cement. 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. 2020; 44(1), International Journal of Molecular Sciences. Mineral trioxide aggregate (MTA) was first described in the scientific literature in 1993 (Lee et al. 2009). 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. Sluyk SR, Moon PC, Hartwell GR. 2009; Chang et al. 2009; Gandolfi et al. J Endod 1995;21:537-42. At this point, the mixture is called clinker. In terms of shape, many of the particles are rather irregular, with some appearing needle-like (Camilleri et al. Dent Traumatol 2012;28:33-41. Regardless, it appears that the addition of bismuth oxide to Portland cement decreases its compressive strength and increases porosity (Coomaraswamy et al. J Endod 1996;22:575-8. J Endod 1998;24:768-71. Mineral Trioxide Aggregate (MTA) is a dental material used in vital pulp therapy and some endodontic procedures. • Tricalcium aluminate. 2004). Thus, water is both a reactant and is contained in the reaction products of MTA. 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. trioxide aggregate mta is a dental material used extensively for vital pulp therapies vpt protecting ... published in english abstract the purpose of this two part series is to review the composition properties and products of mineral trioxide aggregate mta materials pubmed and medline electronic databases MTA has potential and one of the most versatile materials of this century in the field of dentistry. Arens DE, Torabinejad M. Repair of furcal perforations with mineral trioxide aggregate: Two case reports. It is formulated from commercial Portland cement, combined with bismuth oxide powder for radio-opacity. 2010b). MTA embodiments contain superplasticizer and nanosilicate for improved mechanical properties. Accorinte Mde L, Holland R, Reis A, Bortoluzzi MC, Murata SS, Dezan E Jr. Ebrahim J, Mohammad RS, Neda A. Histopathologic responses of dog's dental pulp to mineral trioxide aggregate, bio active glass, formocresol, hydroxyapatite. MTA is a biocompatible and bioactive material which gained rapid acceptance in the field of dentistry. Torabinejad M, Smith PW, Kettering JD, Pitt Ford TR. Nekoofar MH, Adusei G, Sheykhrezae MS, Hayes SJ, Bryant ST, Dummer PM. From ASTM C150/C150M, it is apparent that a strict, fixed composition for Portland cement is not set and a range of constituent component concentrations is tolerable. Placement of mineral trioxide aggregate using two different techniques. The MTA composition support remineralization and biomineralization, and it is suitable for stimulation of hard tissue regeneration. The size of Portland cement particles in the powder of white MTA generally range from <1 µm to 30–50 µm, and the bismuth oxide particles are approximately 10–30 µm (Camilleri 2007). 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). J Endod 2001;27:7-8. It mixes more smoothly, is easier to dispense and has more stable placement, washout resistance and faster clinical setting. The composition of MTA includes : • Tricalcium silicate. Tricalcium silicate sets via the following reaction (Bhatty 1991; Ramachandran et al. Similar results were reported by Camilleri et al. 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 (. 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). J Endod 1995;21:603-8. This is important for understanding the effects of water on properties as discussed below. who compared the composition of Biodentine and MTA Angelus with experimentally produced laboratory cement consisting of tricalcium silicate and zirconium oxide. 2005), which may explain the better handling properties of white versus gray MTA. J Endod 1995;21:295-9. Matt GD, Thorpe JR, Strother JM, McClanahan SB. Pelliccioni GA, Ciapetti G, Cenni E, Granchi D, Nanni M, Pagani S. Koh ET, Ford TR, Kariyawasam SP, Chen NN, Torabinejad M. Prophylactic treatment of dens evaginatus using mineral trioxide aggregate. 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. MTA COMPOSITION. J Endod 2006;32:1094-6. Several researchers have noted the absence of iron in white MTA in contrast to its presence in gray MTA (Camilleri et al. Srinivasan V, Waterhouse P, Whitworth J. Additional minor trace elements may also be present as stated in the MSDS. Once the clinker cools, it is ground to a fine powder size and is now considered Portland cement. 4 It received US Food and Drug Administration approval in 1998. 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. • Bismuth oxide. 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. Int J Pediatr Dent 2009;19:34-47. 2004. Mineral trioxide aggregate (MTA) in dentistry: A review of literature 2003). 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). 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. 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. The main constituent phases are tricalcium and dicalcium silicate and tricalcium al … Mineral trioxide aggregate was developed for use as a dental root repair material by Mahmoud Torabinejad. MTA material can be used as apical and furcation restorative materials as well as medicaments for apexogenesis and apexification treatments. MTA embodiments contain superplasticizerand nanosilicate for improved mechanical properties. Comparative investigation of marginal adaptation of Mineral Trioxide aggregate and other commonly used root-end filling materials. 2005. Int Endod J 2007;40:453-61. This can be used for root-end filling material and as pulp capping material. With its designation as a Class II medical device for root canal filling from the FDA, MTA was subsequently marketed as ProRoot MTA. Int Endod J 2004;37:325-36. Gypsum is added to Portland cement/MTA to alter the setting time and does so primarily by influencing the reactions of the tricalcium aluminate. 2010b; Darvell & Wu 2011). Tetracalcium aluminoferrite (4CaO ∙ Al2O3 ∙ Fe2O3), on the other hand, is considered present in gray MTA but not in white MTA. However, others debate this (Darvell & Wu 2011). 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. Ordinary Portland cement is manufactured by first obtaining the raw materials (typically limestone or calcium carbonate, clay, and/or other materials), crushing the individual raw materials to acquire a smaller particle size, and proportioning them to create a specific composition. - Ref. ENDOCEM MTA is a revolutionary next generation, fast-setting, MTA (Mineral Trioxide Aggregate) product that is pozzolan-based. - Ref. MTA materials have been shown to have a biocompatible nature and have excellent potential in endodontic use. Radio opacity of potential root end filling materials. 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. Mineral Trioxide Aggregate (MTA) cements are hydrophilic materials developed for a number of clinical applications in endodontic therapy such as pulp capping, pulpotomy, apexification, apicogenesis, repair of furcation perforations, root perforations, root‐end filling and recently for orthograde canal filling (Torabinejad & Chivian 1999, Hegde 2009, Parirokh & Torabinejad 2010, Vitti et al. dental literature. J Endod 1993;19:541-4. 2009). 2003; Dammaschke et al. Statistical analysis was performed with the analysis of variance and Bonferroni or Tukey post‐test (α < 0.05). 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. The setting reactions in MTA are approximated to be similar to those in Portland cement, which are best studied by analyzing the hydration of its individual components. In present article, we review the current dental literature on MTA, discussing composition, physical, chemical and biological properties and clinical characteristics of MTA. Although calcium hydroxide is a reaction product, as mentioned below, some does appear in MTA powder, possibly due to reaction with ambient humidity (Camilleri 2008; Chedella & Berzins 2010). Next, the mixture is ground and blended together and introduced into a rotary, cylindrical kiln where it is heated to 1430−1650 ºC. MTA Angelus White Instructions_Download.

Asgary S, Parirokh M, Egbbal MJ, Brink F. Chemical differences between white and gray mineral trioxide aggregate. Shipper G, Grossman ES, Botha AJ, Cleaton-Jones PE. The size and shape of the powder fraction of MTA has been examined by several researchers (Fig. J Endod 2007;33:167-72. Mineral trioxide aggregate (MTA) is a unique material with several exciting clinical applications. MTA has been used for both surgical and nonsurgi … Reproduced with permission of Elsevier. During endodontic treatment of primary and permanent tooth MTA can be used in many ways. MTA is used for creating apical plugs during apexification, repairing root perforations during root canal therapy, and treating internal root resorption. 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. 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). 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). 2003): The principal products are calcium silicate hydrates and calcium hydroxide (also known as Portlandite). This fuses the materials together after a series of reactions which include evaporation of water, dehydration of the clays, and decarbonation of the calcium carbonate (loss of carbon dioxide to yield calcium oxide). Dent Res J 2007;4:83-7. Garcia-Godoy F, Murray PE. E-MTA is a stainproof, tricalcium silicate-based bioactive cement that can be used universally for vital pulp and other endodontic indications in primary and permanent teeth.It is a bioceramic cement that triggers the healing process. THE DENTAL ADVISOR Online delivers practical, reliable, unbiased information. 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. J Endod 2003;29:679-82. Valois CR, Costa ED Jr. 822 MTA Angelus (White): 1 g of White MTA, 3 ml of distilled water, 1 scoop. 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. • Gypsum (5%). 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). Fig. 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. 2006), and also accounts for some of the color difference. Oral Surg Oral Med Oral Pathol Oral Radiol Endod 1996;81:476-9. 2005), but few differences have been noted as to the shape of particles between MTA and Portland cement (Komabayashi & Spångberg 2008). Torabinejad M, Chivian N. Clinical applications of mineral trioxide aggregate. Source: Dammaschke et al. 2.3). As stated in the patent, MTA is comprised primarily of Portland cement. The origins of Portland cement date back to the early to mid-1800s in Britain where the Aspdin family was involved in its development. Effect of an acid environment on leakage of root-end filling materials. During endodontic treatment of primary and permanent tooth MTA can be used in many ways.
