pH and calcium ion release of 2 root-end filling materials.
OBJECTIVE
The purpose of this study was to evaluate the pH and calcium ion release of 2 materials used for root-end fillings and perforation repair.


METHODS
ProRoot and MTA-Angelus were placed in plastic tubes and immersed in glass flasks containing deionized water. After 3, 24, 72, and 168 hours, the water in which each had been immersed was tested to determine the pH changes and released calcium.


RESULTS
The values for pH and calcium ion release were slightly higher for MTA-Angelus than ProRoot. The calcium release and pH of both materials were initially higher.


CONCLUSIONS
The results suggest that both materials release calcium and promote alkaline pH.
