“…[1][2][3][4][5][6] However, the properties of MTA during hydration can be affected by environmental factors, such as acidic pH, 5,7 because it requires ~3-4 h for initial setting, which may cause treatment failure in clinical applications. 8 The sol-gel process is a chemical synthesis method for the preparation of glassbased materials. 9 Through the sol-gel process, the desired chemical and physical properties of a product can be obtained by tailoring different precursors, catalysts, catalyst concentrations, H 2 O/Si molar ratios, and precursor Ca/Si molar ratios.…”

Mineral trioxide aggregate (MTA) is the most frequently used repair material in endodontics, but the long setting time and reduced mechanical strength in acidic environments are major shortcomings. In this study, a novel sol-gel-derived calcium silicate cement (sCSC) was developed using an initial Ca/Si molar ratio of 3, with the most effective mixing orders of reactants and optimal HNO 3 catalyst volumes. A Fourier transform infrared spectrometer, scanning electron microscope with energy-dispersive X-ray spectroscopy, and X-ray powder diffractometer were used for material characterization. The setting time, compressive strength, and microhardness of sCSC after hydration in neutral and pH 5 environments were compared with that of MTA. Results showed that sCSC demonstrated porous microstructures with a setting time of ~30 min, and the major components of sCSC were tricalcium silicate, dicalcium silicate, and calcium oxide. The optimal formula of sCSC was sn200, which exhibited significantly higher compressive strength and microhardness than MTA, irrespective of neutral or pH 5 environments. In addition, both sn200 and MTA demonstrated good biocompatibility because cell viability was similar to that of the control. These findings suggest that sn200 merits further clinical study for potential application in endodontic repair of perforations.

“…ability, and their setting is not greatly affected by moisture (Camilleri 2015, Prati & Gandolfi 2015. The use of MTA for various endodontic applications such as direct pulp capping (Okiji & Yoshiba 2009, Li et al 2015, root-end filling (C ßalıs ßkan et al 2016), perforation repair (Krupp et al 2013) and apical barrier formation in teeth with open apexes (Bonte et al 2015) is reported to result in promising clinical outcomes.…”

Yamamoto S, Han L, Noiri Y, Okiji T. Evaluation of the Ca ion release, pH and surface apatite formation of a prototype tricalcium silicate cement. International Endodontic Journal, 50, e73-e82, 2017. Aim To evaluate the Ca 2+ -releasing, alkalizing and apatite-like surface precipitate-forming abilities of a prototype tricalcium silicate cement, which was mainly composed of synthetically prepared tricalcium silicate and zirconium oxide radiopacifier. Methodology The prototype tricalcium silicate cement, white ProRoot MTA (WMTA) and TheraCal LC (a light-cured resin-modified calcium silicate-filled material) were examined. The chemical compositions were analysed with a wavelength-dispersive X-ray spectroscopy electron probe microanalyser with an image observation function (SEM-EPMA). The pH and Ca 2+ concentrations of water in which the set materials had been immersed were measured, and the latter was assessed with the EDTA titration method. The surface precipitates formed on the materials immersed in phosphate-buffered saline (PBS) were analysed with SEM-EPMA and X-ray diffraction (XRD). Kruskal-Wallis tests followed by Mann-Whitney U-test with Bonferroni correction were used for statistical analysis (a = 0.05).Results The prototype cement contained Ca, Si and Zr as major elemental constituents, whereas it did not contain some metal elements that were detected in the other materials. The Ca 2+ concentrations and pH of the immersion water samples exhibited the following order: WMTA = prototype cement > TheraCal LC (P < 0.05). All three materials produced Ca-and P-containing surface precipitates after PBS immersion, and the precipitates produced by TheraCal LC displayed lower Ca/P ratios than those formed by the other materials. XRD peaks corresponding to hydroxyapatite were detected in the precipitates produced by the prototype cement and WMTA. Conclusion The prototype tricalcium silicate cement exhibited similar Ca 2+ -releasing, alkalizing and apatite-like precipitate-forming abilities to WMTA. The Ca 2+-releasing, alkalizing and apatite-like precipitate-forming abilities of TheraCal LC were lower than those of the other materials.

“…7 Some authors report that MTA can be used to repair root perforations with predictable results, since in examined cases, teeth did not present pathological changes after 12 to 45 months, and more than 82% of treated patients exhibited radiographic success with absence of pain. 8,9,10 According to Siew 2015, in a revision conducted with a total of 188 perforations included in the analysis, a success rate of 72.5% was concluded, regardless of the materials used, and of 80.9% for the use of MTA. These results suggested that non-surgical repair using MTA material can result in a higher success rate compared to other materials.…”

Endodontic retreatment using MTA-based sealants in a tooth with perforation and periapical lesion. Stoma Edu J. 2017;4(4):298-301Introduction: To report an endodontic retreatment with a root perforation and use of reparative cement and filling sealant based on mineral trioxide aggregate (MTA). Summary: Retreatment in teeth with root perforations can reduce the longevity of the treatment, because it depends on the rapid location and proper sealing, with biocompatible materials that promote tissue repair. A female patient came to the dental office complaining of pain in tooth 36, with an indication of retreatment on it. Radiographically, it presented thickening of the periodontal ligament and periapical lesion in the mesial and distal roots, leading to the diagnosis of chronic apical periodontitis. With the help of an operative microscope, it was possible to find a perforation in the most cervical portion in the furcation region of the mesio-vestibular root canal. To treat this perforation, it was filled with MTA HP Repair, to enable preparation of root canals and subsequent filling with MTA Fillapex, through the Schilder Plus technique and execution of a 12mm relief on distal root for placement of the intra-radicular retainer. Rehabilitation of teeth with root perforations can be performed with MTA-based filling sealants, presenting satisfactory results for repairs in cases of perforations and periapical lesions. Key learning points: -Root perforations are accidental unwanted complications that can occur in stages of the endodontic treatment; -The prognosis for endodontic perforations depends on the size and location of the defect and how quickly the perforated area was sealed with biocompatible material.
