“…fluid, blood, or low pH conditions, which mimic clinical situations such as endodontic surgery, are different from those in moisture, which is the recommended setting condition. Furthermore, Kim et al (22) reported that MTA failed to set in the presence of FBS. There also have been reports that the washout of MTA can occur when MTA is used as a retrograde filling material (13,14,22).…”

“…Furthermore, Kim et al (22) reported that MTA failed to set in the presence of FBS. There also have been reports that the washout of MTA can occur when MTA is used as a retrograde filling material (13,14,22). Initial looseness of MTA, ie, it is not set or weakened physical condition, occurs in the presence of tissue fluid or blood flow and may threaten the hermetic sealing of communicating channels between the root canal system and the periradicular tissues, thereby resulting in the failure of endodontic surgery.…”

“…In apical surgery, a long setting time makes it difficult to confirm complete setting of MTA. In addition, washout of the unset MTA can cause relapse of the periapical lesion [6].…”

Background The present study aimed to compare the volumetric changes of three calcium silicate cements after retrofilling and placing under different pH conditions via micro-computed tomography (micro-CT) scan. Methods Forty-two extracted human single-rooted teeth were randomly assigned to three groups according to the retrofilling materials used (Biodentine, Endocem MTA, and ProRoot MTA). Each group was divided into two subgroups according to the setting condition. The teeth in one group were immersed in normal saline for 5 days at room temperature, and the teeth in the other group were immersed in butyric acid (pH = 5.4) for 5 days at room temperature. The volume ratios of the retrofilling material were calculated via micro-CT imaging. Results The volume ratios of the Biodentine and Endocem MTA groups were significantly different between the two setting environment, and these groups had significantly lower filled volume ratio (Vf, %) in the acidic environment than in the saline environment (pH = 5.4). Meanwhile, the volume ratio of the ProRoot MTA group did not significantly differ between the two setting environments. All materials under the acidic setting condition had relative radiolucency in the area in contact with the acidic solution. Conclusion The Vf ratio of the Biodentine and Endocem MTA cements was significantly lower in the acidic environment than in the saline environment. No statistically significant difference was observed in the Vf ratio of ProRoot MTA between the two setting environments.

“…When cleaning an osteotomy site, a root-end filling material can washout, resulting in a weakened root-end seal and its consequences. It has been demonstrated that adding carboxymethyl chitosan or gelatin to cement based on calcium silicates (the primary components of Portland cement in MTA) improves washout resistance ( Kim et al, 2011 ; Formosa et al, 2013 ).…”

Mineral Trioxide Aggregate (MTA) has been a material of revolution in the field of dentistry since its introduction in the 1990s. It is being extensively used for perforation repairs, apexification, root-end filling, obturation, tooth fracture repair, regenerative procedures, apexogenesis, pulpotomies, and as a pulp-capping material because of its desired features such as biocompatibility, bioactivity, hydrophilicity, sealing ability, and low solubility. Even though its application is wide, it has its own drawbacks that prevent it from reaching its full potential as a comprehensive replacement material, including a long setting time, discoloration, mud-like consistency, and poor handling characteristics. MTA is a material of research interest currently, and many ongoing studies are still in process. In this review, the newer advancements of this versatile material by modification of its physical, chemical, and biological properties, such as change in its setting time, addressing the discoloration issue, inclusion of antimicrobial property, improved strength, regenerative ability, and biocompatibility will be discussed. Hence, it is important to have knowledge of the traditional and newer advancements of MTA to fulfill the shortcomings associated with the material.
