Present status and future directions: Hydraulic materials for endodontic use
International Endodontic Journal, Volume 55, Issue S3, Page 710-777, May 2022., 2022 Abstract Background Hydraulic materials are used in Endodontics due to their hydration characteristics namely the formation of calcium hydroxide when mixing with water and also because of their hydraulic properties. These materials are presented in various consistencies and delivery methods.

International Scholarly Research Notices, Volume 2014, Issue 1, 2014., 2014 Physicochemical properties of pozzolan Portland cement were compared to ProRoot MTA and MTA BIO. To test the pH, the samples were immersed in distilled water for different periods of time. After the pH analysis, the sample was retained in the plastic recipient, and the electrical conductivity of the solution was measured. The solubility and radiopacity
