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). General Dental Sciences, Marquette University, USA. However, others have observed trace amounts of iron in white MTA (Belío-Reyes et al. 2.3). Mineral trioxide aggregate (MTA) in dentistry: A review of literature Chirag Macwan, Anshula Deshpande 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. The composition of MTA includes : • Tricalcium silicate. 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. Ding SJ, Kao CT, Shie MY, Hung C Jr, Huang TH. INTRODUCTION Independent analysis suggests that the material of Mineral Trioxide Aggregate (MTA) is identical to Portland cement. 2005) but greater amounts of bismuth (as Bi2O3 for radiopacity), and, therefore, its Portland cement component is of purer form. MTA is a mixture of Portland cement and bismuth oxide, which is added to enhance the radiopacity of the material. J Endod 2003;29:679-82. Longitudinal sealing ability of mineral trioxide aggregate as a root-end filling material. Additional minor trace elements may also be present as stated in the MSDS.

With its designation as a Class II medical device for root canal filling from the FDA, MTA was subsequently marketed as ProRoot MTA. … 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). 2003). 822 MTA Angelus (White): 1 g of White MTA, 3 ml of distilled water, 1 scoop. 2003). Srinivasan V, Waterhouse P, Whitworth J. Tetracalcium aluminoferrite (4CaO ∙ Al2O3 ∙ Fe2O3), on the other hand, is considered present in gray MTA but not in white MTA. Fig. Int Endod J 2002;35:245-54. J Endod 1995;21:295-9. This also holds true for white MTA versus gray MTA (Asgary et al. J Endod 2007;33:167-72. 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 has been used for both surgical and nonsurgi … 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.

Dent Res J 2007;4:83-7. 2005), but few differences have been noted as to the shape of particles between MTA and Portland cement (Komabayashi & Spångberg 2008). Compared with Portland cement, MTA typically has less heavy metal content (Cu, Mn, Sr) (Dammaschke et al. It mixes more smoothly, is easier to dispense and has more stable placement, washout resistance and faster clinical setting. 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). MTA embodiments contain superplasticizer and nanosilicate for improved mechanical properties. This can be used for root-end filling material and as pulp capping material. J Endod 2001;27:703-5. Dominguez MS, Witherspoon DE, Gutmann JL, Opperman LA. Mineral trioxide aggregate (MTA) is a unique material with several exciting clinical applications. 2005, 2006). 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. Fig. MTA Angelus White Instructions_Download. Less of the latter component is contained in white MTA versus gray MTA, but it is still present (Asgary et al. Sluyk SR, Moon PC, Hartwell GR. In both animal and human studies, MTA materials have been shown to have excellent potential as pulp-capping and pulpotomy medicaments. • Silicate oxide. 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). • Tricalcium aluminate. MTA materials provide better microleakage protection than traditional endodontic repair materials using dye, fluid filtration, and bacterial penetration leakage models. MTA has potential and one of the most versatile materials of this century in the field of dentistry. 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). In terms of shape, many of the particles are rather irregular, with some appearing needle-like (Camilleri et al. MTA is a biocompatible and bioactive material which gained rapid acceptance in the field of dentistry. Oral Surg Oral Med Oral Pathol Oral Radiol Endod 1996;81:476-9. 5. 2005), which may explain the better handling properties of white versus gray MTA. The MTA compositions include optional radiocontrast and nano-enriched leachable fluorine, nitrate, strontium, and phosphate. Comparative study of white and grey mineral trioxide aggregate (MTA) simulating a one or two step apical barrier technique. 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.

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. 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 (. It is a new remarkable biocompatiblematerial with exciting clinical applications pioneered by Dr. Mahmoud Torabinejad, Loma Linda University, in 1993. 1-3 The chemical composition of MTA was determined by Torabinejad et al. New materials claiming better performance are continuously being introduced in the market to optimize the care of den … 2.1 Gray and tooth-colored ProRoot MTA. 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. Administration.2 MTA is commercially available as a ProRoot MTA (Tulsa Dental Products, Tulsa, OK). Dent Traumatol 2001;17:163-6.

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. 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. 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. Mineral trioxide aggregate (MTA) is a unique material with several exciting clinical applications. Mineral trioxide aggregate (MTA) was first described in the scientific literature in 1993 (Lee et al. Today, it is a very common hydraulic cement due to its inclusion in concrete, stucco, and mortar. Shah PM, Chong BS, Sidhu SK, Pitt Ford TR. 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 COMPOSITION. 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 DENTAL ADVISOR Online, the place to go when you are searching for in-depth information regarding dental products, manufacturers, industry news and research. Overall, the Portland cement fraction of MTA appears to be more refined than industrial ordinary Portland cement. Int Endod J 2007;40:453-61. This is important for understanding the effects of water on properties as discussed below. Additional minor trace elements may also be present as stated in the MSDS. The two versions of mineral trioxide aggregate (MTA; gray and white) have enjoyed clinical success in endodontics since 1995. The MTA composition support remineralization and biomineralization, and it is suitable for stimulation of hard tissue regeneration. Reproduced with permission of Elsevier. The hydration reactions of the two minor components of Portland cement are influenced by gypsum. 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. 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. J Endod 1996;22:575-8. 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. Vitti RP, Prati C, Silva EJ, Sinhoreti MA, Zanchi CH, de Souza e Silva MG, https://www.jorr.org/text.asp?2014/6/2/71/152914, Bulletin of the National Research Centre. 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 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. 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). Additionally, magnesium (or a magnesium oxide form) is also frequently observed in greater proportion in gray MTA than in white MTA (Song et al. 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. 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.

As stated in the patent, MTA is comprised primarily of Portland cement. Fig. Bismuth oxide is included in MTA to serve as a radiopaque agent because Portland cement is not sufficiently radiopaque for dental purposes. 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). 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). Gypsum is added to Portland cement/MTA to alter the setting time and does so primarily by influencing the reactions of the tricalcium aluminate. 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. 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. The origins of Portland cement date back to the early to mid-1800s in Britain where the Aspdin family was involved in its development. The two most important hydration reactions are those of the greatest constituents, tricalcium silicate and dicalcium silicate. Mineral trioxide aggregate was developed for use as a dental root repair material by Mahmoud Torabinejad. 2005; Monteiro Bramante et al. 1993) as an aggregate of mineral oxides added to “trioxides” of tricalcium silicate, tricalcium aluminate, and tricalcium oxide silicate oxide. The cement is made up of calcium, silicon and aluminium. 2003): The setting of dicalcium silicate is similarly given by the following reaction (Bhatty 1991; Ramachandran et al. Keywords: Biocompatible dental material, Mineral Trioxide Aggregate, MTA. J Endod 2001;27:540-2. MTA has potential and one of the most versatile materials of this century in the field of dentistry. 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). Once the clinker cools, it is ground to a fine powder size and is now considered Portland cement. Tricalcium silicate sets via the following reaction (Bhatty 1991; Ramachandran et al. Several researchers have noted the absence of iron in white MTA in contrast to its presence in gray MTA (Camilleri et al. 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. Thus, water is both a reactant and is contained in the reaction products of MTA. Faraco IM Jr, Holland R. Response of the pulp of dogs to capping with mineral trioxide aggregate or a calcium hydroxide cement. J Endod 2006;32:1094-6. 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). 2.4) (Dammaschke et al. 2006), and also accounts for some of the color difference. Source: Lee et al. Torabinejad M, Chivian N. Clinical applications of mineral trioxide aggregate. MTA is a hydraulic type of cement, meaning that it sets by reacting with water, and is then stable in water. 2008; Comin-Chiaramonti et al. MTA is used for creating apical plugs during apexification, repairing root perforations during root canal therapy, and treating internal root resorption. During endodontic treatment of primary and permanent tooth MTA can be used in many ways. However, others debate this (Darvell & Wu 2011). Effect of an acid environment on leakage of root-end filling materials. 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. Thus, substituting Portland cement for MTA is not advised in clinical procedures. Reproduced with permission of Elsevier. 2005). • Bismuth oxide. ENDOCEM MTA is a revolutionary next generation, fast-setting, MTA (Mineral Trioxide Aggregate) product that is pozzolan-based. Nekoofar MH, Adusei G, Sheykhrezae MS, Hayes SJ, Bryant ST, Dummer PM. 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. Radio opacity of potential root end filling materials. Since its introduction in the 1990s several studies have demonstrated its use in various clinical applications. 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. 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). 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. 820 MTA Angelus (Gray): 1 g of Gray MTA, 3 ml of distilled water, 1 scoop.

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. 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). MTA embodiments contain superplasticizerand nanosilicate for improved mechanical properties. The physical and cytological properties of white MTA mixed with Na. Ease of manipulation as well as the unique ability to stimulate osteogenesis and cementogenesis make this biocompatible material a perfect choice for endodontic repair.

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. J Endod 1999;25:728-30. 2010). The size and shape of the powder fraction of MTA has been examined by several researchers (Fig. 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. 2006).

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. MTA materials have been shown to have a biocompatible nature and have excellent potential in endodontic use. Next, the mixture is ground and blended together and introduced into a rotary, cylindrical kiln where it is heated to 1430−1650 ºC. 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. 2010b). 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. 2003): The principal products are calcium silicate hydrates and calcium hydroxide (also known as Portlandite). 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. who compared the composition of Biodentine and MTA Angelus with experimentally produced laboratory cement consisting of tricalcium silicate and zirconium oxide. Comparatively, ordinary Portland cement contains approximately double the amount of calcium sulfate species as found in MTA. However, others debate this (Darvell & Wu 2011). 2009; Chang et al. Statistical analysis was performed with the analysis of variance and Bonferroni or Tukey post‐test (α < 0.05). Torabinejad M, Hong CU, McDonald F, Pitt Ford TR. 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. In present article, we review the current dental literature on MTA, discussing composition, physical, chemical and biological properties and clinical characteristics of MTA. 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.
