Abstrakt: MTA has been proposed for various treatment alternatives due to its high biocompatibility. However delayed setting times may limit its use. Objectives: The aim of this study was to evaluate the effect of adding a setting accelerator 5% or 10% CaCl2 to MTA on the pH and calcium ion release of MTA (ProRoot MTA, Dentsply, Tulsa Dental, Tulsa, OK). Materials and Methods: MTA powder was mixed with sterile water with or without CaCl2 followed by measurement of pH and calcium ion release at baseline, 1, 3 and 24 hours with a pH meter (Sentron 2001, Integrated Sensor Technology, Roden, Netherlands) and an atomic absorption spectrophotometer (Perkin- Elmer 1100 B, Weiterstadt, Germany). Results: 10% CaCl2 added specimens revealed immediate elevation in pH which continued during all time intervals(p<0.01). The highest calcium release was also observed in groups with CaCl2. Conclusion: The results of this study suggest that CaCl2 as a setting accelerator enhances the biological properties of mineral trioxide aggregate by increasing pH and calcium ion release.
