摘要：

Objective. The purpose of this study was to evaluate the pH and calcium ion release of 6 materials used for root-end filling and perforation repair. Study design. Gray ProRoot MTA, gray MTA-Angelus, white MTA-Angelus, and CPM were compared to 2 experimental ones: MTA-exp, also based in Portland cement with a modified mixing liquid, and MBPc, an epoxy-resin based cement containing calcium hydroxide. After 3, 24, 72, and 168 hours the water in which each sample had been immersed was tested to determine the ph and calcium ion release. Results. All the analyzed materials showed alkaline pH and capacity to release calcium ions; however, a tendency of reduction of these characteristics was noted for all the analyzed materials, except for the MBPc, which showed a slight increase of pH among the 3 initial periods. Conclusion. The results suggest that all materials investigated presented alkaline pH and ability of release of calcium ions. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2009; 108: 135-139)
