- Objective. The aim of this study was to compare the pHs and calcium ion releases of newly developed, calcium phosphate-based root canal sealers (Capseal I and II) with those of Sealapex (SA) and Sankin Apatite Root Sealer III (SARS III). Study design. Each material (n = 10) was mixed, inserted into polyvinyl chloride (PVC) tubes, and immersed in a vial containing deionized water. The control group consisted of empty PVC tubes (n = 10). The pHs and calcium ion releases were measured by pH meter and ICP-AES (inductively coupled plasma atomic emission spectrometer) at 24 hours and 96 hours, and at 7, 15, and 28 days. The results were analyzed with the Kruskal-Wallis test. Results. Capseal I and II produced pHs and calcium ion releases higher than or equal to those of SA and SARS III (P < .05). Conclusions. Capseal I and II resulted in higher alkalinity and higher calcium ion releases than SA and SARS III. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2011; 112: e23-e28)
