These case reports support this hypothesis. However, in one cases (Case 4), pulpotomy with MTA … Three months later, animals were anesthetized and sacrificed. MTA has been reported to have superior biocompatibility and sealing ability and is less cytotoxic than other materials currently used in pulpal therapy. ... A metal or plastic spatula can be used for mixing on a glass slab or paper pad to form a paste of putty-like consistency. 25, 26), gently washed and lightly dried. The first material introduced was Mineral Tri-oxide Aggregate, which, due to its favourable biological properties, gained importance initially. 1) has revolutionized endodontics, since its introduction to dentistry in 19931 (it has been on the dental market since about 1998). 23). The surface was evaluated for any evidence of penetration or fracture at 15x magnification. J. Appl. In vitro compatibility of Proroot MTA cement in comparison with two different fillers used in clinical practice, was examined by testing the adherence, viability, proliferation and secretion of collagen of osteoblast-like cells. Dentistry MTA abbreviation meaning defined here. He is an adjunct clini Min KS, Park HJ, Lee SK, Park SH, Hong CU, Kim HW, Lee HH, Kim EC. References. human body. Bogen, G., Kim, J.S. For assessment of pH change and calcium ion release polyethylene tubes filled with the materials were soaked in distilled water for 7 and 14 days. At present, researchers in the field of biomaterials are focusing on the oral hard and soft tissue engineering with bioactive ingredients by activating body immune cells or different proteins of the body. Sixty primary molars of thirty healthy children using split mouth design aged between 4 and 6 years were treated by pulpotomy technique. Electron probe microanalysis results indicated that lime (CaO), silica (SiO2), and bismuth oxide (Bi2O3) were the dominant compounds in each case and were present at comparable levels in either of the types of mineral trioxide aggregate analyzed. White ProRoot MTA (Dentsply Tulsa Dental, Johnson City, TN, USA) was mixed and packed into cylindrical polycarbonate tubes. properties and applications. Although the dentin bridge formed by calcium hydroxide (CH) is incomplete due to tunnel-like defects, it has been used in several endodontic applications, such as pulp capping. In contrast, the resin replicas of resected and filled root ends had no artifacts. Direct pulp capping with mineral trioxide aggregate, JADA, vol.139, pp. 17), the MTA (Angelus, Brazil/Clinical Research Dental) is prepared by mixing the powder and liquid according to the manufacturer’s instructions. J Clin Pediatr Dent. The data were subjected to Kruskal-Wallis and Conover tests (alpha = 0.05). Although the study is imperative to suggest the clinical and radiographic success, it is difficult to forego the actions which are present due to the chemical action of the formaldehyde with reference to fixation with the protein. Asgary S, Parirokh M, Eghbal MJ, Ghoddusi J, Eskandarizadeh A. SEM evaluation of neodentinal bridging after direct pulp protection with mineral trioxide aggregate. 18). They have Responses were received from 46/65 (70.8%) postgraduate trainees. Introduction: and Phosphates. Alexandra Mussolino de Queiroz; Sada Assed; Mario Roberto LeonardoI; Paulo Nelson-Filho; Léa Assed Bezerra da Silva. During endodontic treatment of primary and permanent tooth MTA can be used in many ways. After root-end resection and ultrasonic preparation, 72 root sections were randomly allocated to three groups and filled with dental amalgam and cavity liner, Super-EBA, or MTA. The implant sites were excised and prepared for histological evaluation. Pulp exposures were performed on the occlusal floor of 40 human permanent premolars. However, a lower response of CH30 was observed for the dentin bridge formation, when compared with MTA30 and MTA60 groups. However, its drawbacks especially its high cost, discoloration potential, difficulty in handling, and long setting time cannot be overlooked. The scientific papers were then screened for their relevance to the intended objectives. The teeth sealed with Ketac-Endo showed two cases of partial closure and different degrees of chronic inflammatory reaction. This page is to help clinicians and researchers understand and discuss MTA. The use of MTA (Angelus, Brazil/ Clinical Research Dental, London, ON) (Fig. Recent advances in the field of endodontics have greatly improved the outcome and success rate of dental materials. 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. ProRoot MTA exhibited significant higher calcium ion release value after 14 days (P value ≤ 0.05). Eighty-eight single-rooted freshly extracted human teeth were cleaned, shaped, and obturated with gutta-percha and root canal sealer. The principle conclusions of this study are that there are no significant differences in MTA and formocresol. If only HV SEM viewing conditions are used for MTA and amalgam root-end fillings, a correction factor of 3.5 and 2.2, respectively, may be used to enable relative comparisons of gap size to LVW conditions. Proper diagnosis and treatment planning helped restore a tooth that would have been lost. This case report will highlight one such case where a tooth was diagnosed as having a gingival overgrowth through a perforation during prior endodontic treatment. Results showed no inflammatory reaction of apical tissue and total closure of the apical foramen of all the teeth sealed with MTA. ... MTA has been widely used in the recent years for pulp capping, partial pulpotomy, perforation repair, resorption repair, repair of fracture , , root end filling, apical barrier for tooth with necrotic pulp and open apex , coronal barrier for regenerative endodontics , root canal sealer. This study investigated the use of Mineral Trioxide Aggregate (MTA) as an apical barrier by comparing the sealing ability and set hardness of white and gray MTA. It was found that using either doxycycline or chlorhexidine (CHX) instead of distilled water, had no effect on MTA's sealing ability [31]. Use of MTA for Direct Pulp CappingThis combination of desirable qualities makes MTA “the material of choice” for cases of pulp exposure in both primary teeth and permanent teeth13,14 (Figs. (ABSTRACT TRUNCATED AT 250 WORDS). Statistical analysis using a McNemar test with a significance of p < 0.05 found the number of roots in which dry MTA powder set at 72 hours versus 12 hours was statistically significantly different (p = 0.0133). Masoud Parirokh, DMD, MS,* and Mahmoud Torabinejad, DMD, MSD, PhD. Specimen cracking, and the size and extent of the crack were noted. The canal was packed with dry powder, and the coronal and apical 4 to 5 mm was sealed with nail varnish. After delivering a mandibular block, and isolation with the rubber dam (Paro Dam – Clinical Research Dental) the clinical photograph of the distal caries is shown in Figure 9. 2006;32:1094-6. Relative frequency ofcalcification of FC, MTA, HA and BAG groups were 75, 51.9, 69.7 and 54.8 percent, respectively. Effect of Mineral Trioxide Aggregate on Dentin Bridge Formation and Expression of Dentin Sialoprotein and Heme Oxygenase-1 in Human Dental Pulp. 1) has revolutionized endodontics, since its introduction to dentistry in 19931 (it has been on the dental market since about 1998). Each group of 20 tubes was subdivided; 10 samples of each length had MTA placed and condensed by the hand method and the other 10 by the ultrasonic method. The root canals were instrumented and filled by the lateral condensation technique with the sealers studied. The purpose of this research was to determine and compare the composition of white mineral trioxide aggregate and gray mineral trioxide aggregate. Light pressure was applied to control haemorrhage. Endodontic practice is influenced to a great extent by different stages of root development and the type of tissue present within the roots. One of the current biomaterials is known as bioactive glass (BAG). 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. Beta-tricalcium phosphate, white mineral trioxide aggregate, white Portland cement, ferric sulfate, and formocresol used as pulpotomy agents in primary pig teeth. An acid pH significantly reduced dye leakage of Geristore (0.67 vs. 3.93 mm) and MTA with CPC matrix (0.54 vs. 2.41 mm), whereas leakage of all other materials was not affected by pH. 2008 Apr;41(4):273-8. Your email address will not be published. Relative frequency of histopathologic outcomes of dental pulp was analyzed and reported. Gap size was recorded at eight fixed points along the dentine-filling material interface on each section when uncoated wet (LV wet (LVW)) and dry under LV (0.3 Torr) in a JEOL JSM-5800 SEM and backscatter emission (LV dry uncoated (LVDU)). Moreover, histologically mineral trioxide aggregate was a considerably better material than calcium hydroxide or acid-etched dentin bonding in maintaining the integrity of the pulp. Pitt Ford TR, Torabinejad M, Abedi HR, Bakland LK, Kariyawasam SP. Microleakage was assessed at 24 h, 72 h, 2 wk, 4 wk, 8 wk, and 12 wk, using a fluid filtration measurement system. The sections were observed from the viewof inflammation, hyperemia, necrosis, vitality, calcification and dentinal bridge. MTA materials provide better microleakage protection than traditional endodontic repair materials using dye, fluid filtration, and bacterial penetration leakage models. MTA is a mixture of Portland cement and bismuth oxide, which is added to enhance the radiopacity of the material. Statistically significant differences were found between tubes containing GMTA in concentrations of 50, 25 and 12.5 mg/ml and tubes containing similar concentrations of WMTA (p < 0.001). These questions contained types of MTA material, mechanical, chemical, physical properties of MTA, marginal adaptation and sealing ability, antibacterial properties, reaction with other dental materials, biocompatibility, and clinical performance. To protect the MTA during its setting, a light cured glass ionomer (Fuji 2 LC GC America, Alsip, IL) is injected precisely over the MTA site with a Skini Syringe and Endo-Eze canula (Ultradent/Clinical Research Dental) (Figs. Mineral trioxide aggregate (MTA) was introduced to dentistry as a root-end filling material. Use of MTA in conjunction with an intraradicular endodontic file splint for treatment of horizontal root fracture- A case report. This article will look at the success, practicality, and scientific basis for use in pulp capping procedures, particularly in permanent teeth, as MTA has been described very recently as “the material of choice”10 for this treatment. Conclusions: MTA is a unique material with various advantages. There was no significant difference in the results for any of the four lengths of MTA placed by the hand method (p > 0.9). The cavities were restored with amalgam and the pulpal tissue reactions were assessed by light and electron microscopy (transmission and scanning) after healing intervals of 1, 2 or 3 weeks. Care is needed to deliver regenerative endodontic procedures that maintain or restore the vitality of teeth, but which also disinfect and remove necrotic tissues. In conclusion, MTA exhibited better biological properties than Ketac-Endo. The teeth were randomly divided into four groups, and the perforations were all repaired with mineral trioxide aggregate (MTA) and then covered with either a wet or dry cotton pellet for 24 or 72 h. Instron testing was used to measure the force required to displace the material from the perforation. Histological analysis was performed 2 months after treatment. Under an agreement between MetLife and MTAB/MTA Insurance Agency, Inc,, MTAB markets the MetLife Group Dental Insurance Plan and receives compensation relating to the sale of insurance. After careful cutback of the glass ionomer cement and a cleaning of all the margins, a Triodent contoured matrix band was placed, followed by the insertion of a Wave-Wedge. This importance is because of its extensive use as apical restorative material as well as a medicament for Apexogenesis and Apexification treatment. One hundred fifty-six single-rooted human extracted teeth received root canal treatment, apicoectomy, and ultrasonic root-end preparations. A condensation pressure of 1.68 MPa conferred the maximum compressive strength; however, it was not statistically different. Properties of MTAMTA stands for mineral trioxide aggregate, denoting the three dominant oxides in the material’s composition, namely – calcium, aluminum and selenium. Fig. Concentrations of calcium ion release were measured using inductively coupled plasma optical emission spectroscopy. Absence of a known solvent for this material. JOE – Volume 36, Number 5, May 2010.21. 2006 Winter;31(2):72-6.14. Six groups each of 10 specimens were subjected to pressures of 0.06, 0.44, 1.68, 3.22, 4.46 and 8.88 MPa respectively. as endodontic sealers and as aids in regeneration. It is the first restorative material that consistently allows for the overgrowth of cementum, and it may facilitate the regeneration of the periodontal ligament. 13) may complicate access for distal molars, but the distancing of the head of the hand-piece from the occlusal cavo-surface margins allows better visualization of the caries removal process. 11) the head of the hand-piece interferes with adequate vision of the caries removal process. We found that the cells attached to the rough surface of Proroot MTA cement and spread onto the rough surface. This review highlights various challenges in the treatment of open apex, with emphasis on MTA compared with other materials. Study Selection: Abstracts and full text articles were used to identify studies describing the composition, manipulation, properties, types, and clinical features. Six of the animals were killed at 50 days and nine were killed at 150 days. 20). These included vertical root fracture, apexification, perforation repair and repair of a resorptive defect. A trend was observed for higher condensation pressures to produce lower surface hardness values. The goal of modern dentistry is to provide patients with a holistic solution by providing functional restoration. A homogenous zone of crystalline structures was initially found along the pulp-MTA interface, whilst pulpal cells showing changes in their cytological and functional state were arranged in close proximity to the crystals. The aim of this study was to present a review of the reported literature on: (i) the physical and chemical properties; and (ii) clinical applications of mineral trioxide aggregate (MTA) in the practice of paediatric dentistry. They Moreover, the cells on Proroot MTA were viable, grew, and released some collagen even at 72 h, while cell metabolism and growth was dramatically reduced onto sEBA and amalgam surfaces. Clinical long-term evaluation of MTA as a direct pulp capping material in primary teeth. Scanning electron microscopy analysis was performed, and the weight percentage of elements found in the dentin of a nontreated tooth versus the bridge formed in the exposed specimen was established. Statistical analysis of the results showed less periradicular inflammation and more fibrous capsules adjacent to MTA, compared with amalgam. 28). Five groups of 10 specimens were prepared using pressures of 0.06, 0.44, 1.68, 3.22 or 4.46 MPa. In this experimental group, pulp inflammation was observed in all but three cases. When excavating deep caries and using a regular length bur (Fig. MTA pulpotomy using NuSmile NeoMTA. Originally developed as a root-end filling material, its main components are tricalcium silicate, tricalcium aluminate, tricalcium oxide, and silicate oxide. Examination of the original samples showed numerous artifacts in the longitudinal sections of the specimens. individual cases, experience of the operator, familiarity with handling various materials, and patient's availability for follow-up appointments. Zirconia, Bioactive glass, Glass ceramics, Hydroxyapatite, In Endodontics, they can be broadly classified 305-315.18. He can be reached at ndofriedman@rogers.com. Thickness of fibrous capsules measured five different areas by the digital imaging and the mean values were scored. This paper aims to review the biological and physicochemical properties of mineral trioxide aggregate (MTA) with respect to its ability to induce reparative dentinogenesis, which involves complex cellular and molecular events leading to hard-tissue repair by newly differentiated odontoblast-like cells. Overall, 94% and 88% of the specimens capped with MTA-Angelus and ProRoot, respectively, showed either total or partial hard tissue bridge formation (P > 0.05). Histopathologic outcomes of MTA was more proper than those of BAG, HA and FC. Clinical impressions have generally been favourable and support the findings of laboratory and animal-based investigations. During endodontic treatment of primary and permanent tooth MTA can be used in many ways. No significance difference was found between 2- and 3-mm-thick MTA (P >.05). Its setting time is four hours, so any definitive restorations must be done after this period so as not to disturb the seal of the MTA. calcium silicates, they are also referred to as Calcium Silicate materials. Role of Mineral Trioxide Aggregate (MTA) and Calcium Hydroxide in Conservative Dentistry as Pulp Capping Material: A Review Fuad Abdo Al-Sabri 1, *, Ahmed Mohammed El-Marakby 2, 3, Nashwan Mohammed Qaid 4 1Department of Operative Dentistry, Faculty of Dentistry… Bioceramics, classification and their advantages. 27), air thinned and the ethanol solvent evaporated. The purpose of this study was to evaluate whether intracoronal delivery of an apical barrier of mineral trioxide aggregate (MTA) placed ultrasonically, non-ultrasonically, or ultrasonically with the addition of an intracanal composite resin provided a better seal against bacterial leakage. The purpose of the present study was to evaluate the physicochemical and cytologic properties of mineral trioxide aggregate (MTA) mixed with distilled water and Na(2)HPO(4) buffer solution. Each slide was graded histologically according to previously published criteria. However, the first publications advocating the use of Portland cements in dentistry occurred before the end of the nineteenth century. The results suggest that 15% Na(2)HPO(4) buffer can be successfully used as an accelerator of MTA. Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2008;105:536-42.7. Because of the lack of long-term evidence to support the use of regenerative endodontic procedures in traumatized teeth with open apices, revascularization regeneration procedures should only be attempted if the tooth is not suitable for root canal obturation, and after apexogenesis, apexification, or partial pulpotomy treatments have already been attempted and have a poor prognosis.
