Majority of subjects asserted the sealing ability (89.5%) and antibacterial effects (71.6%) of MTA material. 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. Forty hollow glass molds were taken in which MTA was placed. J Clin Pediatr Dent 2006;30(3):203-10.10. Higher condensation pressures resulted in fewer voids and microchannels when analysed with SEM. To be healthy! Results Harvard MTA endodontic cement showed significant lower solubility and higher pH values compared with that of ProRoot MTA. The aim of this literature review was to assess the clinical performance of MTA to establish the evidence level for its effectiveness in vital pulp therapy, perforation repair, and retrograde root canal filling. Amalgam, IRM, and MTA mixed with CHX caused a weak inflammatory response on days 15, 30, and 60. Jaw Joint and Muscle Strain/Sprain Treatment Technique. The presence of some moisture in the perforation during placement was advantageous in aiding adaptation of MTA to the walls of the perforation, but there was no significant difference in MTA retention when a wet or dry cotton pellet was placed in the pulp chamber during the setting time (p > 0.05). In this experimental group, pulp inflammation was observed in all but three cases. The regeneration of immature permanent teeth following trauma could be beneficial to reduce the risk of fracture and loss of millions of teeth each year. J Endod 2010;36:16-27.3. currently used in the fields of Endodontics along with their Mineral Trioxide Aggregate: A Comprehensive Literature Review-Part III: Clinical Applications, Drawbacks, and Mechanism of Action. To study mutagenicity of Intermediate Restorative Material (IRM), Super-EBA, and a potential root-end filling material, mineral trioxide aggregate (MTA), strains of Salmonella typhimurium LT-2 (TA 98, R-factor strain and TA 1535, non-R-factor strains) were used in a standard Ames mutagenicity assay. MTA material can be used as apical and furcation restorative materials as well as medicaments for apexogenesis and apexification treatments. The antibacterial effects of gray-colored MTA (GMTA) and white-colored MTA (WMTA) against Enterococcus faecalis and Streptococcus sanguis were assessed in vitro using the tube dilution test. A literature review suggests that Mineral Tri oxide Aggregate (MTA) is the most favourable and recommendable material for single-visit apexification, even in cases when regenerative endodontics cannot be performed. Abstract Background Insolubility is the main requirement for ideal root end filling material to provide perfect sealing ability. There was a prominent tubercle on the occlusal surface of the mandibular second premolar. e Bakland, L.K.(2008). Other applications: MTA was also reported to be used as a root canal filling of retained primary teeth [107] and in furcation perforation repair and resorption repair of primary teeth, ... Alkaline pH levels and calcium ions in the fluid surrounding, which is unfavourable for bacterial growth. Physical and chemical properties of MTA Fillapex 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. Endodontic practice is influenced to a great extent by different stages of root development and the type of tissue present within the roots. The children were then examined clinically and radiographically every 6 months. Four-millimeter-thick MTA was significantly more effective than the other thicknesses tested (P <.05). Journal of the Pakistan Medical Association. It is not recommended for obturation of primary teeth that are expected to exfoliate since it is anticipated that Mineral Trioxide Aggregate would be absorbed slowly, if at all. Statistical analysis of the results showed less periradicular inflammation and more fibrous capsules adjacent to MTA, compared with amalgam. A plus point of MTA is its biocompatibility and hermetic apical seal with no micro-leakage. MTA Benefits and its licensed insurance agency, MTA Insurance Agency, Inc., are corporations owned by MTA. Seale NS, Glickman GN. Reactions of connective tissue to amalgam, intermediate restorative material, mineral trioxide aggregate mixed with chlorhexidine. 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. They tended to appear around microchannels. The present randomized, controlled prospective study evaluated the histomorphological response of human dental pulps capped with two grey mineral trioxide aggregate (MTA) compounds. Faraco Jr IM, Holland R (2001) Response of pulp of dogs to capping with mineral trioxide aggregate or a calciumhydroxide cement. Histological examination of these teeth showed an apparent continuous dentin bridge formation in both teeth, and the pulps were free of inflammation. Mineral trioxide aggregate (MTA) was introduced to dentistry as a root-end filling material. A 4-mm thickness of MTA followed with an intracanal composite resin demonstrated a significantly greater resistance to root fracture than MTA followed with gutta-percha and sealer (one-way ANOVA with Newman-Keuls multiple comparison test, p < 0.01). Parirokh M, Torabinejad M. Mineral trioxide aggregate: a comprehensive literature review-part I: chemical, physical, and antibacterial properties. Electronic literature search of scientific papers from January 1993 to June 2008 was carried out on the MEDLINE, Embase, Entrez Pubmed, and Scopus databases using specific key words. J Am Dent Assoc 1996; 127:1491-4.16. We recommend that root-end filling materials should have a radiopacity greater than that for root canal sealers. The root canals were instrumented and filled by the lateral condensation technique with the sealers studied. 17), the MTA (Angelus, Brazil/Clinical Research Dental) is prepared by mixing the powder and liquid according to the manufacturer’s instructions. The spectral analysis proved that placement of glass-ionomer cement over MTA after 45 minutes did not affect its setting reaction and calcium salts may be formed in the interface of these two materials. These cases show that mineral trioxide aggregate can be used as an alternative to existing materials in the proplylactic treatment of dens evaginatus. The canals on half of the roots were instrumented and obturated with gutta-percha and sealer, and their access cavities were sealed with MTA. Numerous compounds have been used as root-end filling materials. The access cavities of the teeth in this group were left open to the oral cavity. The antibacterial effects of each material were measured in millimeters and the data were analyzed using one-way and two-way analysis of variance and Scheffé tests to determine the statistical differences between the antibacterial effects of the test materials. As these bioactive materials are mainly based on, Access scientific knowledge from anywhere. The results of this study suggest that the thickness of 4 mm is most adequate for the use of MTA as a root-end filling material. Furcation perforations were created in 32 extracted maxillary and mandibular molars. A second purpose was to determine whether intracanal composite resin or gutta-percha and sealer placed against an apical barrier of MTA provided greater resistance to root fracture. The MTA setting time and pH value were evaluated. Calcium silicate based cements are active biomaterials; that is, they have the ability to induce favourable response from the host tissue, ... MTA when placed in direct contact with human tissues, releases calcium ions for cell proliferation and creates an antibacterial environment by its alkaline ph which modulates cytokine production and encourages migration and differentiation of hard tissue producing cells. The data were subjected to Kruskal-Wallis and Conover tests (alpha = 0.05). Bacterial leakage occurred in 6 (33%) of 18 in the non-ultrasonic MTA group, 2 (11%) of 18 in the ultrasonic MTA group, and 1 (6%) of 18 in the ultrasonic MTA-composite group. 2006;32:1094-6. In our experimental system, Saos-2 cells challenged with Proroot MTA for 24 and 72 h showed a better behaviour than the cells exposed to the other compounds under assay. as endodontic sealers and as aids in regeneration. The results suggest that 15% Na(2)HPO(4) buffer can be successfully used as an accelerator of MTA. Examination of the original samples showed numerous artifacts in the longitudinal sections of the specimens. We use cookies to make your website experience better. Mineral trioxide aggregate reacts with tissue fluids to form a hard tissue apical barrier.

Figure 19 shows the first increment placed. The use of MTA (Angelus, Brazil/ Clinical Research Dental, London, ON) (Fig. This study was conducted to observe the response of dogs' dental pulp to mineral trioxide aggregate (MTA) and a calcium hydroxide cement when used as pulp capping materials. MTA materials have been shown to have a biocompatible nature and have excellent potential in endodontic use. Animals were anesthetized and pulpotomized. 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. This importance is because of its extensive use as apical restorative material as well as a medicament for Apexogenesis and Apexification treatment. The goal of modern dentistry is to provide patients with a holistic solution by providing functional restoration. When slight displacement occurred at 24 h the material demonstrated the ability to re-establish resistance to dislodgement from the dentin wall. To avoid the risk of toxic effects in vivo, the biological compatibility of filling materials has to be assessed. When excavating deep caries and using a regular length bur (Fig. This study was conducted to observe the rat subcutaneous connective tissue reaction to the implanted tubes filled with amalgam, IRM, MTA, and MTA mixed with CHX. Sections of 5 to 6 microm thickness were cut by a microtome and stained with hemotoxylin eosin and examined under a light microscope. The bioactive properties make BAG applicable to several clinical applications involving the regeneration of hard tissues in medicine and dentistry. Study Selection: Abstracts and full text articles were used to identify studies describing the composition, manipulation, properties, types, and clinical features. Specimen cracking, and the size and extent of the crack were noted. A very practical advantage of MTA is that, unlike many other dental materials, it sets in the moist environment that is omnipresent in dentistry. 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 first material introduced was Mineral Tri-oxide Aggregate, which, due to its favourable biological properties, gained importance initially. Root-end fillings were placed in 20 extracted single-rooted maxillary teeth. Root-filled teeth were mounted in an apparatus and then challenged with protein solution. Sumer M, Muglali M, Bodrumlu E, Guvenic T. Reactions of Int Endod J. Methods Solubility was evaluated after 7- and 14-day immersion time of specimens in phosphate buffer saline solution (PBS); the mean weight loss was evaluated and solubility was calculated as a percentage of the weight loss. 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. Apical barriers of white and gray MTA were placed to a thickness of 2 mm or 5 mm. The final removal of the caries is accomplished with the use of a new sterile diamond round bur, which causes less tissue damage to the pulp than the round carbide bur (which also will be contaminated by the caries excavation). Relative frequency of histopathologic outcomes of dental pulp was analyzed and reported. The setting time and compressive strength of these materials were determined according to methods recommended by the British Standards Institution. properties and applications. Three materials were used: calcium hydroxide, acid-etched dentin bonding, and mineral trioxide aggregate. Bioceramics, classification and their advantages. To examine the effect of condensation pressure on surface hardness, microstructure and compressive strength of mineral trioxide aggregate (MTA). Finally, unlike most dental materials, MTA actually NEEDS moisture to set so it thrives in a moist environment. Mineral trioxide aggregate (MTA), is unique endodontic cement that was initially introduced as a material for root perforation repair. resorbable Calcium phosphates, among others. (B) Routine endodontic therapy was performed in the apical portion of … Dentistry Today March 200312. Several case reports give these procedures a good prognosis as an alternative to apexification. After 6 months the teeth were removed as part of planned orthodontic treatment. The sections were then air-dried, gold-coated and gap size was recorded once again at the fixed points under HV (10(-6) Torr; HV dry coated (HVDC)). 2005;31:101-3. At this time hand condensation should be considered the preferred method for placement of MTA. It was concluded that the most significant differences observed were between the measured concentrations of Al2O3 (+122%), MgO (+130%), and especially FeO (+1000%) when gray mineral trioxide aggregate was compared with white mineral trioxide aggregate.

August 1, 2011 After condensation the samples were evaluated with a light microscope and radiographs for the degree of adaptation of the MTA to the tube walls and for the presence of voids within the MTA material itself. JOE – Volume 36, Number 3, March 20105. Deposition of hard tissue of osteotypic form was found in all teeth in direct contact with the capping material and the associated crystalline structures. 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. Direct pulp capping with mineral trioxide aggregate, JADA, vol.139, pp. In dentistry, its uses include dental restorative materials, mineralizing agents, as a coating material for dental implants, pulp capping, root canal treatment, and air-abrasion, and in medicine it has its applications from orthopedics to soft-tissue restoration. Arnaldo Castellucci, MD, DDS. This article reviewed the composition, types, properties of MTA and also its applications in the clinical dentistry. Condensation pressure may affect the strength and hardness of MTA. The Wave-Wedge does not cause separation but only serves to adapt the matrix gingivally. The samples were obturated immediately (one-step) or after the MTA set for 24 h (two-steps). In five out of the 40 teeth bacteria were present in pulp tissue. Is mineral trioxide aggregate more … Studies have shown that the materials currently used to repair these iatrogenic accidents are inadequate. MTA demonstrated excellent sealing ability throughout 12 wk of fluid immersion, comparable with that observed for Super-EBA. Eighty-eight single-rooted freshly extracted human teeth were cleaned, shaped, and obturated with gutta-percha and root canal sealer. 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)). The results demonstrated an 80% agreement for findings between the light microscopy and radiographic evaluation. MTA is a mixture of Portland cement and bismuth oxide, which is added to enhance the radiopacity of the material. 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. Using a slow-speed diamond saw, 40 roots were longitudinally sectioned into two halves. Direct pulp capping with mineral trioxide aggregate in a primary molar: a case report. The tooth was then placed into a saline-soaked "Oasis" to simulate a clinical condition. Ng FK, Messer LB. The Use of Mineral Trioxide Aggregate in Clinical and Surgical Endodontics. Fig. Better outcomes in pulpotomies on primary molars with MTA. ProRoot MTA exhibited significant higher calcium ion release value after 14 days (P value ≤ 0.05). A combination of the key search terms mineral trioxide aggregate, MTA, pulp therapy, clinical applications, and pediatric dentistry were used. 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 … 3). J Clin Pediatr Dent. The aim of this study was to histopathologically examine the biocompatibility of the high-copper amalgam, intermediate restorative material (IRM), mineral trioxide aggregate (MTA), and MTA mixed with chlorhexidine (CHX). Results: The respondents of this questionnaire were 195 subjects. MTA has shown excellent results in pulp capping, pulpotomy, periapical surgery, as well as an excellent potential for apexogenesis and apexification. Following amputations made with MTA, it has been reported that colouring in the teeth may be seen [21]. No significant difference was observed between the two materials (P > 0.05) in terms of overall histological features (hard tissue bridge, inflammatory response, giant cells and particles of capping materials). The area is delicately dried with the use of tissue in cotton pliers (Fig. With the emergence of other novel tricalcium silicate based materials that overcome MTA’s key limitations, they are competing to be the next potential dentin substitutes for the various clinical application in which MTA has been used. 20). JOE – Volume 36, Number 3, March 2010, p.400-41311. This review highlights various challenges in the treatment of open apex, with emphasis on MTA compared with other materials. 18). It was found that Table 1. After initial recapitulation of the occlusal anatomy with a 7802 bur (Fig. ... Limitations-Long setting time (37,38) Difficult handling and high cost Potential tooth discoloration (39). vol.13 no.2 Bauru Apr/June 2005. Recommendations for the selection of regenerative and conventional procedures based on the type of tooth injury, fracture type, presence of necrosis or infection, periodontal status, presence of periapical lesions, stage of tooth development, vitality status, patient age, and patient health status will be reviewed.
