“…[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.…”

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.

“…[4] Mineral trioxide aggregate (MTA) is currently the material of choice for repairing root canal perforations and endodontic treatment. [5,6] MTA is a water-based biocompatible material that promotes regeneration of surrounding tissues. [7][8][9] Several studies have reported the antibacterial activity of MTA, but the results are inconsistent.…”

“…1,2 In both instances, there was also evidence of cementum covering the restoration site. Since these initial studies, there are records of good clinical success when it has been used as a root-end filling material 3,4 (Figures 1 and 2) for root perforation repair, 5 direct pulp capping, However, because the grey colour affected aesthetics, the composition of MTA was altered to reduce the iron content and become more tooth-coloured. This was introduced as white ProRoot MTA in March 2002 13 ( Figure 5).…”

Calcium silicate materials have been recently introduced to dentistry and have found wide applications in endodontics because of their favourable biological properties. This review discusses materials that have become available commercially as well as those that are currently experimental. The compositional aspects of Mineral Trioxide Aggregate (MTA) are discussed with modifications and the development of newer materials. Based upon this information, a definition and classification for calcium silicate materials has been proposed. Calcium silicate materials have properties that make them suitable for use in endodontics. Research with hybrid materials may lead to the development of a cement with more desirable characteristics. Clinical Relevance: Dentists should be aware of the chemistry of the calcium silicate group of materials that includes Mineral Trioxide Aggregate and several newer materials.
