AB  - OBJECTIVE: The objective of this study was to analyze the microstructure and 
      crystalline structures of ProRoot MTA, Biodentine, CEM Cement, and Retro MTA when 
      exposed to phosphate-buffered saline, butyric acid, and blood. METHODS AND 
      MATERIALS: Mixed samples of ProRoot MTA, Biodentine, CEM Cement, and Retro MTA 
      were exposed to either phosphate-buffered saline, butyric acid, or blood. 
      Scanning electron microscope (SEM) and energy-dispersive X-ray spectroscopic 
      (EDX) evaluations were conducted of specimens. X-ray diffraction (XRD) analysis 
      was also performed for both hydrated and powder forms of evaluated calcium 
      silicate cements. RESULTS: The peak of tricalcium silicate and dicalcium silicate 
      detected in all hydrated cements was smaller than that seen in their unhydrated 
      powders. The peak of calcium hydroxide (Ca(OH)(2)) in blood- and acid-exposed 
      ProRoot MTA, CEM Cement, and Retro MTA specimens were smaller than that of 
      specimens exposed to PBS. The peak of Ca(OH)(2) seen in Biodentine specimens 
      exposed to blood was similar to that of PBS-exposed specimens. On the other hand, 
      those exposed to acid exhibited smaller peaks of Ca(OH)(2). CONCLUSION: Exposure 
      to blood or acidic pH decreased Ca(OH)(2) crystalline formation in ProRoot MTA, 
      CEM Cement and Retro MTA. However, a decrease in Ca(OH)(2) was only seen when 
      Biodentine exposed to acid. CLINICAL RELEVANCE: The formation of Ca(OH)(2) which 
      influences the biological properties of calcium silicate cements was impaired by 
      blood and acid exposures in ProRoot MTA, CEM Cement, and Retro MTA; however, in 
      the case of Biodentine, only exposure to acid had this detrimental effect.
