title: Physical properties of CH61, a newly developed root canal sealer.
abstract: This study was performed to evaluate the physical properties (sealing, flow, radio-opacity, working time, and solubility) of a newly developed root canal sealer, CH61. It was compared with Canals, Sealapex, and AH26, which are typical commercially available root canal sealers. The sealing ability was evaluated by dye penetration. The flow was evaluated by two methods. One was flow in the vertical dimension, and the other was disk diameter. Radio-opacity, working time, and solubility were performed in accordance with the standards of the International Organization for Standardization. No dye penetration after immersion for 24 h was noted. In CH61, and there were significant differences between the values for CH61 and Canals, Sealapex, or AH26 (p < 0.001). For flow, the results differed from method to method. The radio-opacity decreased in the following order: AH26, Canals, CH61, and Sealapex. The solubility was the lowest for CH61. This study showed that CH61 had excellent sealing properties and low solubility.
