The aim of the present study was to investigate the role of prostaglandin E2 … Similar to calcium hydroxide-based materials, the antimicrobial action of MTA is most likely associated with elevated pH resulting from ionization that releases hydroxyl ions. A Bioactivity Index (IB) was introduced to rank the level of bioactivity of a specific material [].This index is defined as the time taken for more than 50 % of the interface to bond to bone (t 0.5) and is represented by IB = 100/ t 0.5bb.. 17. None of the teeth exhibited clinical or radiographical failure during the follow-up period of up to 24 months. 5MO has the same indications, mechanism of action, and benefits of MTA, better sealing ability and mechanical properties than MTA, better antibacterial property, better handling and application than MTA, and it is less expensive than MTA. A large number of studies have demonstrated that MTA has a better sealing ability than that of traditional materials such as amalgam, glass ionomer cement, and zinc oxide-eugenol cement by means of dye leakage, bacterial leakage, and fluid infiltration tests (reviewed by Roberts et al. 2007). In conclusion, the observed results and the mechanism of action of white MTA is very similar to those reported for gray MTA (9,15). However, calcium chloride reduces the compressive strength of set MTA [144]. The handling properties of MTA are recognized to be less than ideal, since the working time is limited to a few minutes—even though this slow-setting material requires approximately three hours for initial setting [7, 82]—and the cement mixture is somewhat grainy and sandy. ability of MTA[13]. Use of MTA as a pulpotomy agent in permanent teeth has demonstrated excellent histological and clinical results.4,7,12,13 MTA has demonstrated acceptable biocompatibility, sealing ability and the ability to promote healing in8, They identified the precipitates as calcium-deficient poorly crystalline carbonated apatite, which had been transformed from an initially formed amorphous calcium phosphate. This article explains the composition, chemical and physical properties, action mechanism, handling, preparation, advantages and disadvantages of the MTA in temporary teeth pulpotherapy as a substitute for formocresol in clinical treatments performed according to studies in the literature. Such dissolution of calcium hydroxide may be a key mechanism behind the biological properties of MTA. •Its mechanism of action is the cauterization of the superficial pulp tissue Sheller B. Electrosurgical pulpotomy: a pilot study in humans. These studies showed 100% success rate of MTA, both clinically and radiographically, through different follow-up protocols., It is a biocompatible material and its sealing ability is … In one prospective study, the success rates of partial pulpotomies using either GMTA or calcium hydroxide were compared with a mean follow-up period of 34.8 months [135]. also reduces the setting time [149] while maintaining biocompatibility in vitro [150]. Regarding primary teeth, one study evaluated the clinical outcome of direct pulp capping with either WMTA or Dycal in 25 symmetrical pairs of carious primary molars [131]. Attempts have also been made to improve the working (and physical) properties of MTA by developing new calcium silicate-based materials [108, 152–157]. However, MTA and calcium hydroxide share several biological properties that contribute to the induction of reparative dentinogenesis, mostly due to the fact that set MTA acts as a “calcium hydroxide-releasing material.” Thus, the dentinogenic mechanism of MTA may be attributable to the natural wound healing process of exposed pulps, which is considered to be the mechanism involved in calcium hydroxide-induced reparative dentinogenesis. Two previous publications provided a comprehensive list of articles from November 1993–September 2009 regarding the chemical and physical properties, sealing ability, antibacterial activity, leakage, and biocompatibility of MTA. In addition, a case report in which partial pulpotomies were conducted on 2 cases of dens evaginatus and histologic examination was conducted after 6 months; complete dentin bridge formation without pulp inflammation was demonstrated [136].

MTA requires approximately three hours for initial setting [7, 82], and the reaction continues slowly for weeks [82, 88, 89] and probably months. / Tay, Franklin R. Mineral Trioxide Aggregate in Dentistry: From Preparation to Application. [99] first reported the formation of white precipitates with a globular ultrastructure on GMTA following immersion in PBS solution. Hydroxyapatite crystals form over MTA when it comes in contact with tissue synthetic fluid. However, an antibacterial Attempts are being conducted to improve the working properties of MTA via the addition of setting accelerators and the development of new calcium silicate-based materials. Pulpotomy Method of Application Mechanism of action Commercial Availability Composition of MTA Clinical applications in Pediatric endodontics Setting Reaction Direct pulp capping a poorly crystallized hydrated salt and pulp tissue is usually responsible for direct ediatric endodontics poses a … 12 This results in a high (2001) advocated that the powder water ratio for MTA should be 3:1(P: W). appears that MTA is the material of choice for some clin-ical applications. However, this activity of MTA is limited against some facultative bacteria and has no effect on strict anaerobic bacteria [119], and it is also weaker than the actions of zinc oxide-eugenol cements [119, 124]. The human studies with ferric sulfate are … MTA 1. This mix should be cover with moistened cotton pellet to prevent dehydration of mix. (1999) and Schmitt et al. The available literature suggests that MTA is more efficient at inducing reparative dentinogenesis in vivo compared with calcium hydroxide-based materials. Therefore, we believe that the mechanism of action of MTA is similar to that of calcium hydroxide. J … This appears to be a common characteristic of calcium silicate-containing biomaterials [106, 107]. MTA has been recommended primarily as a root-end filling material, but it has also been used in pulp capping, pulpotomy, apical barrier formation in teeth with open apexes, repair of root perforations, and root canal filling. [14] Nevertheless, in vitro studies suggest the presence of dentinogenic mechanisms specific to MTA, since MTA can stimulate hard tissue-forming cells to induce matrix formation and mineralization.

Lallier, “Root-end filling materials alter fibroblast differentiation,”, R. Haglund, J. One explanation for this mechanism is the above-mentioned ability of MTA to spontaneously produce apatite precipitates in the presence of phosphate-containing fluids [57, 58, 99, 100, 102], since materials with an apatite layer are known to form a chemical bond with calcified tissues such as bone [103, 107, 117]. SEM analysis of water-immersed MTA revealed an increased porosity, which may have been caused by the dissolution of calcium hydroxide and other hydration products [46]. Park, S.-K.

Its mechanism of action is similar to the traditional pulpotomy agent calcium hydroxide (CH) because MTA releases CH inducing dentine formation when applied to vital pulp . This is an open access article distributed under the Overall, the clinical outcome of direct pulp capping and pulpotomy with MTA seems quite favorable, although the number of controled prospective studies is still limited. Pulpotomy is a minimally invasive procedure performed in children on a primary tooth with extensive caries but without evidence of root pathology. Copyright © 2020 Elsevier B.V. or its licensors or contributors. Numerous studies have yielded promising results using MTA for root end filling, perforation repair, vital pulp therapy (direct pulp capping, partial or full pulpotomy) and apical barrier formation.4 MTA is currently recommended as the material of choice for the treatment of teeth with immature apices. They concluded that the crystal precipitates on both MTA materials were chemically and structurally similar to hydroxyapatite. acidic.

A porosity increase and the formation of a Ca-leached layer have also been reported for Portland cement [94, 95] and thus these properties are derived from the parent material. Method: MTA was performed in two visits treatment protocol on direct pulp capping in adult.. The marginal adaptation of MTA is in general better than that of traditional materials [111–114], although one study [114] reported that marginal adaptation did not correlate with leakage. Blood contamination has little impact on the degree of leakage [87]. The apatite was deposited within collagen fibrils, and the interfacial layer composed of apatite was accompanied with tag-like structures that extended into the dentinal tubules [58]. Thus, the capacity of MTA to induce hard tissue repair of exposed pulps may depend heavily on its ability to create a local environment in which the inherent wound healing capacity of the pulp is not deteriorated. MTA and Portland cements are virtually devoid of phosphorus [5–7]. MTA preparations from different origins may vary in their antimicrobial activity.
