Summary: This in vitro study examined the effects of OrthoMTA, a commercially available dental bioactive cement, on demineralized dentine using complementary analysis techniques. The study found that OrthoMTA can effectively recover the calcium species of the original tooth, demonstrating its potential for use in both direct pulp capping and remineralization of affected dentin in IPC procedures.

Summary: The study evaluated the effect of MTA on in vitro bone resorption events mediated by RANKL and the influence of Ca2+ and Al3+ on osteoclastogenesis inhibition by MTA. Results showed that MTA significantly suppressed osteoclastogenesis and activity induced by RANKL, suggesting its potential to inhibit bone resorption events in periapical lesions. Additionally, Ca2+ and Al3+ were found to play a role in this process.

Summary: This study aimed to evaluate the cytotoxicity, biocompatibility, and osteoinductive profile of MTA Flow in comparison with MTA Angelus. The results showed that MTA Flow exhibited non-cytotoxic behavior, better biocompatibility, and the ability to stimulate tissue mineralization. The immunoexpression of bone matrix proteins in the MTA Flow group was similar to or higher than that observed in the MTA Angelus and control groups.

Summary: This study investigated the effects of sulphoaluminate cement replacing Portland cement ratio (CRPR) and calcium sulfate to sulphoaluminate cement ratio (CCR) on the performance of the cement. The results showed that the variation of CRPR or CCR influenced the setting time, strength, water absorption, and chloride diffusion of the cement. The competition between aluminate in Portland cement and ye'elimite in sulphoaluminate cement in the hydration process affected the pore structure and hydration of the cementitious system.

Summary: This study investigated the pH-dependent chloride desorption isotherms for OPC paste exposed to MgCl2, CaCl2, and NaCl solutions. The study found that the Langmuir isotherm is most suitable for describing chloride binding in ground OPC paste, with chloride binding influenced predominantly by the cation-type of the chloride. Results from thermogravimetric analysis and thermodynamic modeling confirmed the mechanism of chloride binding with cement hydrates. The dissociation of bound chlorides in different chloride solutions was found to be affected by the pH of the exposure solution.

Summary: This study investigated the influence of different ratios of C3S and C2S on the physical and chemical characteristics, hydration process, and microhardness properties of MTA samples. Results showed that higher C3S ratio samples induce faster hydration, leading to decreased fluidity and shorter working and setting times, as well as decreased microhardness.

Summary: Pulpotomy is an effective treatment for permanent teeth with irreversible pulpitis. Symptomatology, root apex development, and type of biomaterial are significant predictors for treatment success. This meta-analysis is the first study to evaluate the clinical outcome of pulpotomy for carious teeth with irreversible pulpitis, identifying the stage of root development and type of biomaterial as predictors for treatment success.

Summary: This study evaluated the effects of three different concentrations of nano-graphene oxide (GO) powder on the setting time, compressive strength, pH, calcium ion release, and antibacterial activity of mineral trioxide aggregate (MTA). The results showed that the addition of 1% GO significantly improved the performance of MTA without compromising its compressive strength.

Summary: The addition of nano-CaCO3 accelerates the hydration of Portland cement and improves its mechanical properties. The correct water-to-powder ratio is essential for manipulating the hydraulic cement. Different concentrations of nano-CaCO3 and water-to-powder ratios affect the physicochemical properties of white Portland cement, especially setting-time and compressive strength.

Summary: The study evaluated the performance of two reciprocating glide path systems, WO and RP, in creating a glide path in mesial root canals of mandibular molars and assessed the torsional resistance of instruments. The results showed that WO and RP instruments performed similarly in most aspects, with RP instruments having higher torsional strength and less angular deflection compared to WO. The study also found significant differences in angular deflection values between the new and used WO groups.

Summary: This study used micro-computed tomographic imaging to analyze the quality of endodontic preparation of mesial canals in mandibular molars provided by 3 instrumentation protocols. The results showed that using larger tip files with lower taper 1mm before the foramen resulted in a larger volume of apical preparation, centralization of the preparation, and safe apical dentin wear.

Summary: This study evaluated the accuracy of electronic apex locators (EALs) in determining working length in primary teeth pulpectomies. The results showed that the electronic measurement tends to be shorter than radiographic measurement, while other methods showed no difference. However, due to the low methodological quality and very low certainty of the evidence, caution is needed when interpreting these results.
