Mineral Trioxide Aggregate Applications in Endodontics: A Review

Abstract

A current topic in dentistry concerns the biocompatibility of the materials, and in particular, conservative dentistry and endodontics ones. The mineral trioxide aggregate (MTA) is a dental material with biocompatibility properties to oral and dental tissues. MTA was developed for dental root repair in endodontic treatment and it is formulated from commercial Portland cement, combined with bismuth oxide powder for radiopacity. MTA is used for creating apical plugs during apexification, repairing root perforations during root canal therapy, treating internal root resorption, and pulp capping. The objective of this article is to investigate MTA features from a clinical point of view, even compared with other biomaterials. All the clinical data regarding this dental material will be evaluated in this review article. Data obtained from the analysis of the past 10 years’ literature highlighted 19 articles in which the MTA clinical aspects could be recorded. The results obtained in this article are an important step to demonstrate the safety and predictability of oral rehabilitations with these biomaterials and to promote a line to improve their properties in the future.

Introduction

The mineral trioxide aggregate (MTA) is a hydrophilic and biocompatible endodontic cement, capable of stimulating healing and osteogenesis. It consists of a powder of fine trioxides (tricalcium oxide, silicon oxide, bismuth oxide) and other hydrophilic particles (tricalcium silicate, tricalcium aluminate, responsible for the chemical and physical properties of this aggregate), which hardens in the presence of humidity.[1] [2] [3] [4] [5] The hydration of the powder results in the formation of a colloidal gel with pH 12.5, which solidifies in a structure in about 3 to 4 hours.[6] [7] [8] [9]

In the past 10 years, the MTA found its application in the field of dentistry with specific fit within the conservative and endodontic treatments. A dental trauma is an event that cannot be predicted and usually it is not easy for the clinicians to manage it. The dentist should therefore be prepared to intervene in patient who has suffered a dental trauma. Early intervention is often crucial to improve the prognosis of the trauma itself. In the presence of a coronal fracture with dentine exposure, the primary objective should be to seal dentinal tubules. Especially in a young patient, the size and number of dentinal tubules are large: even a small amount of exposed dentin therefore allows a large number of plaque bacteria and their metabolites to move to the underlying pulp and cause inflammation. An occurrence of this type could, sometimes in short time, lead to necrosis. When the dental trauma has caused a pulp exposure, the emergency intervention consists with the management of the exposed pulp. One of the treatments, besides the endodontic treatment, is direct capping or partial pulpotomy. Partial pulpotomy could be performed using MTA. The MTA could be applied as cement for its high compatibility, which has a mechanism similar to calcium hydroxide (Ca(OH)₂) (extremely basic) and therefore a powerful antibacterial.

Unlike Ca(OH)₂, however, the MTA hardens, reaching a good consistency; it is, therefore, extremely suitable for any restoration. Fast hardening therefore allows partial pulpotomies performed with MTA to be restored in a definitive manner.[7]

Pulp consisting of a cellular component, vessels and nerves; this tissue is called mature mucosal connective tissue. Endodontic therapy is used if a tooth carious or traumatic injury has caused an irreversible alteration of the pulp tissue and its necrosis. It is also possible to use this method if the dental element is to be involved in prosthetic rehabilitations, which due to the considerable reduction of the dental tissue, it would determine, with high probability, an irreversible pulp alteration. During endodontic treatment, blood contamination should be absolutely avoided, and the roots canal system needs to be dry, to obtain a successful root canal filling. During direct pulp capping or perforation sealing, it is fundamental to control the bleeding and obtain a dry field too. The mechanism of action of the MTA is related with the clinical features of the human oral cavity. MTA, when placed in direct contact with human tissues, is able to release calcium ions for cell proliferation. Moreover, it creates an antibacterial environment by its alkaline pH, regulating the cytokine production. Therefore, it favors the migration and differentiation of hard tissue producing cells forming hydroxyapatite on MTA surface and providing a biological seal. Finally, during a surgical endodontic procedure, the retrograde cavity should be completely dry. This cement differs from all other materials currently in existence, thanks to its biocompatibility, its antibacterial properties, its marginal adaptation, and its sealing capacities, and finally, thanks to its hydrophilic nature. It is important to understand the functioning of this biomaterial, its behavior with contact with other materials used in dentistry, and above all, over time or from a clinical and radiographic point of view.[10] [11] [12] Investigating these topics requires a research into the international literature, which also includes the use of cutting-edge technologies for examination.[13] [14] [15] [16]

The purpose of this review is to evaluate all the recent scientific literature concerning this topic and to evaluate all its clinical features. The evaluation of different studies offers information about the facets of the material related to endodontics, conservative dentistry, and oral surgery.

Synthesis of Results

Çelik et al[20] analyzed differences between two groups of patients involved in pulpotomy treatment. The MTA groups had a 100% success rate at 24 months instead of 89.4% with Biodentine use. According to Erfanparast et al,[21] there are no significant differences on resin-modified Portland cement-based materials versus MTA in direct pulp capping. After 12 months, the success rate for MTA and resin-modified one were 94.5 and 91.8%, respectively. Koc Vural et al[22] evaluated differences between Ca(OH)₂ and MTA. The follow-up term for a total of 100 samples was of 24 months. Four Ca(OH)₂ capped teeth and two MTA capped received endodontic emergency treatments. But there are no significant differences between groups. Kang et al[23] studied clinical differences between three MTA groups (ProRoot MTA, Ortho MTA, and RetroMTA). The success rate at 1 year was high with no significant differences; the success rates were 96, 92.8, and 96%, respectively (as listed in parentheses). Bakhtiar et al[24] investigated differences on third molar pulpotomy between three different materials (TheraCal, Biodentine, and ProRoot). They showed how there were no clinical signs on ProRoot MTA and Biodentine groups as two patients reported significant pain in TheraCal group. Pulp reorganization was seen in 33.33% of ProRoot MTA, 11.11% of TheraCal, and 66.67% of Biodentine groups. Moreover, dentinal bridge formation was seen on 11% of TheraCal and 56% of ProRoot MTA. Asl Aminabadi et al[25] tested clinical differences between four groups for direct pulp capping. Noncaries pulpal exposures were treated with simvastatin, 3Mix, 3Mixtatin, or MTA. At the end of a 12-month follow-up period, the overall success rates were 93.8% (MTA), 91.9% (3Mixtatin), 62.5% (3Mix), and 57.1% (simvastatin). According to the authors, there were no significant differences (p = 0.05) between MTA and 3Mixtatin groups. 3Mixtatin groups had a statistical difference on simvastatin and 3Mix groups (p < 0.01). Another study of Aminabadi et al[26] confirmed 3Mixtatin efficiency on pulp capping. The authors inspected MTA versus 3Mixtatin on direct pulp capping with a 96.8% of success rate against MTA with 48.6% of referred pain. Nowicka et al[27] evaluated differences on direct pulp capping between four groups: Ca(OH)₂, MTA, Biodentine, and Single Bond Universal. The reparative dentin formed in the Ca(OH)₂, MTA, and Biodentine was superior to the Single Bond Universal group. Moreover, the dentin bridges density was the highest in the MTA group and the lowest in the Single Bond Universal group. Kang et al[28] published a report about differences on three MTA materials. At 12 months, the radiographic success rates in these groups were 100% (RetroMTA), 97.4% (Ortho MTA), and 100% (ProRoot MTA). The Kaplan–Meier’s survival function relative to clinical and radiographic rates did not differ between groups. According to Bonte et al,[29] MTA at 12 months produced mineralized barrier in 82.4% of cases instead of Ca(OH)₂ (50%). Pain and tenderness to percussion had disappeared in both groups. In a Petrou et al[30] randomized controlled trial, it was demonstrated at ~6.3 months of time on 86 patients how Ca(OH)₂ versus medical Portland cement versus white MTA did not show any statistical difference. The total success rate was 90.3%. Hilton et al[31] recently published a study about the clinical and radiographic differences on two direct capping materials groups, Ca(OH)₂ versus MTA. MTA showed a less failure rate (p = 0.046). Gandolfi et al[32] analyzed, through a three-dimensional microcomputed tomography (3D micro-CT) analysis, differences between AH Plus and MTA flow on their microstructure. Bernabé et al[33] tested the MTA sealing ability for apicectomy. They filled with MTA plus sonic, ultrasonic, or no vibration. The sonic vibration could improve sealing level. Sönmez et al[34] showed differences on the apical microleakage between AH Plus, MTA Fillapex, and ProRoot MTA. Fillapex had better results about microleakage and there are no statistical differences between AH Plus and MTA. Leye Benoist et al[35] highlighted differences between Ca(OH)₂ and MTA for indirect pulp capping. At 3 months, the success rate of MTA was 93% instead of 73% for Ca(OH)₂. At 6 months, the success rate was 89.6% for MTA instead of 73%. The mean initial residual dentine thickness was 0.23 mm, this value has been increased to 0.121 mm with MTA and 0.136 with Ca(OH)₂ at 3-month time. According to Ghoddusi et al,[36] there are no statistical differences between MTA or zinc oxide eugenol (ZOE) in pulpotomy after a carious or traumatic pulp exposure. Hansen et al[37] considered the pH level with the use of different biomaterials for pulp capping. The authors studied MTA, Endodontic Sealing(ES); control pairs were filled with Ca(OH)₂ (positive group) and saline (negative). The pH was measured at 20 minutes, 3 hours, 24 hours, and 1–2 to 3–4 weeks. The MTA pH was significantly higher during the time than ES (at 1 week, p < 0.0001). Yildirim et al[38] discovered differences on filling between gutta-percha with two methods and MTA. Cervino et al obtained better results with MTA, then showed less microleakage ([Fig. 3]).[7]

Discussion

All the conclusions of the selected articles for this present review have been summarized in this section as follows: Çelik et al[20] evaluated clinical success differences between MTA and Biodentine. The authors showed how both MTA and Biodentine are appropriate options for pulpotomy. According to this study, it seems how the etiology of pulp exposure is the crucial on pulpal response (mechanical or carious) whether or not the kind of material applied. Erfanparast et al[21] concluded that resin-based Portland cement results are comparable to MTA for primary molars after 12 months of follow-up and no significant differences can be underlined between the two biomaterials investigated. Koc Vural et al performed a similar study, about the comparison of two endodontic materials.[22] The authors reported that Ca(OH)₂ and MTA are both accepting pulp-capping materials at a 24-month follow-up term.

Kang et al[23] in a 1-year follow-up study investigated three different materials applied to pulpotomy technique. The procedure was classified as safe and predictable with ProRoot MTA, Ortho MTA, or RetroMTA documented through clinical and radiographical data. Bakhtiar et al[24] published an in vitro study about how some endodontic biomaterials could be efficient than others for the pulp capping procedures. The authors performed histology to evaluate dentinal bridge formation and organization after teeth extraction (disodontiasis third molar). Data demonstrated how Biodentine and ProRoot MTA work better than TheraCal.

According to Asl Aminabadi et al,[25] there are no radiographic and clinical differences between MTA and 3Mixtatin, and it could represent a valid alternative in direct pulp capping. Aminabadi et al[26] evaluated at 24 months the efficiency of 3Mixtatin, showing how this biomaterial could have better clinical result than MTA from a clinical and radiographic point of view. According to the authors, it could represent the future pulp capping material.

Several published articles underlined the clinical features of the MTA just evaluating clinical and radiological data. Nowicka et al[27] demonstrated how the reparative dentin bridges are dependent on the material used. Biodentine and MTA resulted in the highest volumes after the cone beam radiography. According to Kang et al,[28] RetroMTA, Ortho MTA, and ProRoot MTA success rates did not differ and are indistinguishable, and these results indicate that pulpotomy could be performed with a high success rate with all the evaluated biomaterials. Bonte et al[29] showed how there is no statistical difference between Ca(OH)₂ and MTA, but MTA produced a better dentin healing, apexification using MTA could give better results than Ca(OH)₂.

Petrou et al[30] concluded that MTA or medical Portland cements are preferable to Ca(OH)₂ for indirect pulp capping because those materials are nonresorbable materials. Hilton et al[31] showed how MTA is superior for direct pulp capping to Ca(OH)₂. Gandolfi et al[32] concluded in their study, after a 3D micro-CT analysis, that MTA flow created an apatite layer after 7 days, and AH Plus even after 28 days. Bernabé et al[33] showed how MTA could be useful item for root canal filling after apicectomy; moreover, a sonic vibration could improve sealing ability. Sönmez et al[34] concluded that the sealing ability of AH Plus and ProRoot is similar, but MTA Fillapex showed microleakage compared with the other two materials.

Some studies reported how the results could be modified if the evaluation is reported at 3, 6 months, or 1 year after the treatment. This clinical condition demonstrated how the patient response could be individual and not related to the materials or technique applied. According to Leye Benoist et al,[35] a higher success rate was observed in the MTA group instead of Ca(OH)₂. Differences were significant at 3 months but not at 6 months, with no dentine thickness differences, showing time of evaluation importance. Ghoddusi et al[36] concluded that there are no statistical differences between ZOE or MTA treatments, but MTA was successful, expensive, and because of dentin bridges could complicate future root canal therapy. Data reported by Hansen et al[37] demonstrated how the MTA produce an intracanal higher pH than ES. The same result was demonstrated by Yildirim et al.[38] MTA can be used in the root canals as apical filling materials, in particular, in teeth with postcore indication.

All these results extrapolated by the selected articles provide us documented clinical information and the MTA seems to be as having excellent abilities from the point of view of biocompatibility, as could be seen from the studies, but also of stability over time.[39] [40] [41] The nanocharacteristic of the MTA could be related about its interactions with the human tissue during the endodontic treatment. Remineralizing potential intercepting early lesion progression as nanosized calcium phosphate, carbonate hydroxyapatite nanocrystals, nanoamorphous calcium phosphate, and nanoparticulate bioactive glass particularly with provision of self-assembles protein that furnish essential role in biomimetic repair even in the dental field. The unique size of nanomaterials makes them fascinating carriers for dental products.[42] [43] [44] [45] [46] [47] [48] [49] [50] Thus, it is recently claimed that fortifying the adhesives with nanomaterials that possess biological merits does not only enhance the mechanical and physical properties of the adhesives but also help attain and maintain a durable adhesive joint and enhanced longevity. It is also necessary to report how these conservative therapies often do not expose patients to invasive surgical or not risks, practices that in patients with unfavorable systemic conditions would be complex to apply. Accordingly, this review will focus on the current status and the future implications of nanotechnology in preventive and adhesive dentistry. In dental materials, the main applications of nanotechnology have been to achieve better mechanical properties, higher abrasion resistance, less shrinkage, improved optical, and esthetic properties, and to provide antimicrobial properties. Antimicrobial activity is an important property for nanomaterials used in dentistry because of the lack of this property in resin-based materials. MTA is a biomaterial that has numerous possibilities for endodontic therapy, as animal studies and clinical results are highly encouraging. It can also be used in deciduous dentition, with deep carious lesion or exposure to the traumatic pulp intended for endodontic therapy.[51] [52] [53] [54] [55] [56] [57] [58] [59] [60] [61] The MTA could not be used to save all teeth with pulp involvement; however, with a meticulous technique, it could serve as a pulp drug in advance to add to a clinical use. Modern nanotechnology is used in the production of a variety of dental materials such as light-cured composite resins, adhesive systems, impression materials, ceramics, dental implant coatings, and bioceramics, among others. In pediatric age, a whole series of dental malocclusions could occur. There could be different types of dental malocclusions: some are genetic, and others are caused by external factors; the big difference in the treatment of these malocclusions in pediatric and in adulthood is that in children, treatment tends to be much less invasive as the bones have yet to fully develop and it is easier to intervene to correct their shape. Therefore, it should be understood how the absence of a dental element, extracted rather than saved, thanks to an endodontic treatment, even in borderline conditions, thanks to the use of these cements, could have repercussions on the whole stomatognathic system.[62] [63] Moreover, the material is versatile, guaranteeing different uses, and having excellent characteristics in being in contact with the materials for reconstruction.[64] [65] [66] [67] [68] [69] [70] [71] [72] [73] [74] [75] [76] [77]

Conclusion

The results of this review would be certainly useful to fully understand the characteristics and advantages of this biomaterial from a clinical point of view; our structural analysis of the material explains its clinical behavior; and the studies examined are the proof. The numerous clinical, histological, and radiographic tests make this material a safe and predictable material in the endodontic and conservative dentistry fields. Some studies have shown better characteristics than the MTA, above all, from an antibiotic point of view. This could act as a starting point for the improvement of this material and the creation of even better materials.
