The formation of crystals mainly composed of Ca and P has also been demonstrated on the pulpal surface of MTA that had been capped on exposed dog pulps in vivo [64]. 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. This pH rise is due to the progression of calcium hydroxide formation during the hydration process. Review articles are excluded from this waiver policy. In a recent study, Tomson et al (260) demonstrated that WMTA and GMTA release different signaling molecules from dentin powder that might influence their effect on the quality and the rate of calcified bridge formation. MTA also has the ability to interact with phosphate-containing fluids to spontaneously form apatite precipitates, which not only explains its biocompatibility and bioactivity but may also contribute to its sealing ability. Tomson et al showed that GMTA and WMTA The precipitates are also formed at the MTA-dentin interface [57, 58, 99, 105], and thus may play a role in the achievement of a good marginal seal, as will be described below.

Reação do tecido conjuntivo do rato ao implante de tubos de dentina obturados com um agregado de trióxido mineral branco. This appears to be a common characteristic of calcium silicate-containing biomaterials [106, 107]. This indicates the presence of certain bonding mechanisms that may contribute to its sealing ability. Most recently, Reyes-Carmona et al. Taken together, studies have consistently reported that MTA and Portland cement are able to interact with phosphate-containing fluids to form apatite deposits on their surfaces. Moreover, the addition of calcium chloride did not affect the formation of dentin bridges following pulpotomies in dog teeth [70], and thus may not deteriorate the biologic properties of MTA. Success rates of 100% can be attributed to smaller sample size or wider range of patients (5-12 years), which can reduce validity and reliability of results. on clinical evaluation of success of primary teeth pulpotomy using MTA, laser, and Biodentine.

Mixing can be done on paper pad or on a glass slab using a plastic or metal spatula to achieve putty like paste consistency. Method: MTA was performed in two visits treatment protocol on direct pulp capping in adult.. In addition, Si and Al show an increased concentration within the Ca-leached layer [93], probably resulting from the formation and/or accumulation of insoluble components such as calcium silicate hydrate and ettringite. 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. However, the mechanism by which MTA induces dentine repair remains unclear. Another study was conducted by Niranjani et al. mechanism of action of MTA is very similar to the effect of CH on pulp tissue after pulp capping (6). A recent report has documented that the addition of INTRODUCTION Mineral trioxide aggregate (MTA) was developed for use as a dental root repair material by Dr. Mahmoud Torabinejad, (MTA) is the most commonly recommended material for sealing communications between the root canal system and the periodontium and was formulated from commercial Portland cement combined with … A.

[14] MTA requires approximately three hours for initial setting [7, 82], and the reaction continues slowly for weeks [82, 88, 89] and probably months. MTA has been shown to promote a variety of positive cellular responses in vitro when applied directly to the dental pulp (Bonson et al. [14] Calcium oxide, one of its components, is converted into calcium hydroxide when the … 2004; Nakayama et al. 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]. MTA preparations from different origins may vary in their antimicrobial activity. MTA has some known drawbacks such as a long setting time, high cost, and potential of discoloration. We use your LinkedIn profile and activity data to personalize ads and to show you more relevant ads. Nevertheless, MTA has advantages over traditional calcium hydroxide preparations in terms of its structural stability and sealing ability, since calcium hydroxide preparations show a high degree of dissolution and lack sealability [96–98]. This indicates that the calcium ions supplied by portlandite dissolution interact with the phosphate ions in the medium, allowing for the formation of apatite crystals. Introduction: The main aim during any dental treatment is to maintain vital pulp as long as possible.Objective: The aim of this study was to assess clinically the use of MTA in direct pulp capping in adult patient.

Sodium hypochlorite (NaOCl) can be used to promote healing vital pulpotomies as an antibacterial agent. When applied to exposed dog dental pulps, both NEC and MTA show favorable responses characterized by the formation of dentin bridges, while Dycal showed inferior responses accompanied by incomplete dentin bridge formation and pulp inflammation [156]. .
The cement’s setting time is 3 to 4 hours.

Mineral trioxide aggregate: a comprehensive literature review – part III: clinical applications, drawbacks, and mechanism of action. 33 The aim of pulpotomy was to retain a symptom-free, functional primary tooth until it reaches the age of its physiologic exfoliation 2005; Tani-Ishii et al. [99] first reported the formation of white precipitates with a globular ultrastructure on GMTA following immersion in PBS solution. (1998) , Torabinejad et al. One study recommended an admix of 1% methylcellulose and 2% calcium chloride because it improved the handling properties of MTA without reducing its compressive strength [145]. Hydroxyapatite crystals form over MTA when it comes in contact with tissue synthetic fluid. None of the teeth exhibited clinical or radiographical failure during the follow-up period of up to 24 months. This is an open access article distributed under the ) as follows [49, 84, 85]: MTA is hydrophilic and requires moisture to set, which is a favorable property when there is potential for moisture contamination in the clinical setting; moisture from the surrounding tissue may assist the setting [82, 86]. Such properties of apatite formation are considered to be important for explaining the biocompatibility and/or bioactivity of MTA, since the surface precipitation of biocompatible material(s) may be a basis for the bioactivity of several inorganic biomaterials [103, 104]. In a recent review article, on the mechanism of action of MTA on pulpal and periodontal tissues, the following actions are described: when placed, MTA immediately releases calcium ions activating cell attachment and proliferation, and at the same time, the high pH creates an antibacterial environment. Therefore, we believe that the mechanism of action of MTA is similar to that of calcium hydroxide. A study comparing three pulpotomy agents in preschool children suggested MTA success rates were less than 100%. 3, Fig. Sixty days Sixty days after treatment, the animal was sacrificed and the specimens removed and prepared for histomorphological analysis. : +45 35 45 24 31 ... Abstract – Mineral trioxide aggregate (MTA) has over the last two decades begun to take the place of calcium hydroxide (CH) in the treatment of a variety of pulpal and periodontal healing complications following dental trauma. However, the question of why MTA exhibits such a good seal has not yet fully been resolved. They reported that the mechanism of action of white MTA is very similar to that reported for gray MTA. MTA 1. MTA had been likened to calcium hydroxide (Holland et al. In addition, the authors also found that GMTA produces twice as many crystals as WMTA, suggesting that the two MTA materials do not possess the same level of bioactivity [100]. MTA has a similar mechanism of action to calcium hydroxide 11 in that the main component of the material, calcium oxide, when in contact with a humid environment, is converted into calcium hydroxide.

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.. MTA is also used as a pulpotomy dressing for primary teeth and is considered an appropriate alternative to formocresol, since studies comparing MTA and formocresol consistently showed that MTA gave similar to better results both clinically and radiographically [137–143]. 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. They identified the precipitates as calcium-deficient poorly crystalline carbonated apatite, which had been transformed from an initially formed amorphous calcium phosphate. Moreover, Ca ions are continuously released, and the medium maintains a high pH [46–49]. recommended for pulp capping, pulpotomy, apical barrier formation in teeth with open apexes, repair of root perforations, and root canal filling. The minimally invasive endodontic techniques of vital pulp therapy (VPT) are based on improved understanding of the capacity of pulp (nerve) tissues to heal and regenerate plus the availability of advanced endodontic materials. MTA shows slight expansion upon setting [108–110], which may contribute, at least in part, to its good sealing ability. [58] examined the precipitates on various PBS-immersed MTA preparations and Portland cements by means of SEM and XRD and found the presence of amorphous calcium phosphate crystals of different morphologies and Ca/P ratios, which may act as precursors during the formation of carbonated apatite. 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 … / Tay, Franklin R. Mineral Trioxide Aggregate in Dentistry: From Preparation to Application. Using X-ray diffraction (XRD) analysis, the authors identified the crystals as hydroxyapatite, although their calcium-to-phosphorus ratios were different from that reported for hydroxyapatite. 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 … Hydrated MTA is alkaline, and its pH rises from 10.5 to 12.5 three hours after mixing [6, 82]. One less than ideal property of MTA is that it is a slow-setting material like Portland cement. 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. Resource Centre for Rare Oral Diseases, Copenhagen University Hospital, Rigshospitalet, Copenhagen, Denmark Tel. The aim of the present ex vivo study was to assess and compare the electrophysiological effects of WMTA and CEM on F 1 neuronal excitability in Helix aspersa using intracellular recording techniques. MTA was developed and recommended for endodontic procedures cause of it is nontoxic, noncarcinogenic, nongenotoxic, biocompatible, ... mechanism of action of MTA is very similar to the effect of CH on pulp tissue after pulp capping (6).
