“…An in vitro study from the same paper demonstrated that calcium hydroxide (29.4% decrease of cell metabolic activity) caused higher cytotoxic effects to the MDPC-23 cells than MTA (9.9% decrease) 27) . The success rate of MTA (ProRoot) for direct pulp capping was reported to be 80.3% (195 cases) after 2 year-recall, which was higher than that of calcium hydroxide (Life, Kerr) (68.5%, 181 cases) 29) . Another clinical trial showed the overall success rate for MTA (ProRoot) was 80.5% (170 teeth total), with 33 failed teeth (19.5%) in 10 years 10) .…”

Direct pulp capping is the placement of a dental material directly over exposed pulp to prevent dental pulp from dying and avoid the need for root canal treatments. Calcium hydroxide and calcium silicates/mineral trioxide aggregates (MTA) have been commonly used for direct pulp capping with great success clinically. In recent years, resin-modified calcium hydroxide and calcium silicates have been developed with the advantages of precise placement, command set, and superior physical strength. As pulp capping materials would be in direct contact with the pulp, the cytotoxicity and biocompatibility is of particular importance in order to avoid pulp irritation and maintain pulp vitality. Therefore, this review article will summarize the cytotoxicity and biocompatibility of direct pulp capping materials, particularly resin-modified materials.

“…[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.

[25][26][27][28] Mente y colaboradores evaluaron 149 pacientes (con un promedio de seguimiento de 27 meses) en los que se realizaron tratamientos de recubrimiento directo posterior a exposición pulpar, con hidróxido de calcio y MTA. 27 Obtuvieron una mayor tasa de éxito con MTA (78%) al compararlo con hidróxido de calcio (60%), concluyendo que el MTA parece ser más 25 Their study included a large sample of 376 patients who were monitored for up to 2 years.…”
