Abstract
Objective To examine the apical sealing ability of iRoot FS through micro-CT and 3D reconstruction software Mimics,as well as the dye leakage study.Methods A total of 34 extracted permanent teeth were retrofilled by iRoot FS,MTA,then scanned by micro-CT,3D models were reconstructed by software Mimics.The volume between the mater and the root was calculated.Then the teeth were placed in India ink for the day leakage study,Robertson's technology was used to make specimens transparent.The apical leakage was measured under the microscope.Results MicroCT scanning found that there was no significant difference in voids between iRoot FS group and MTA group (P ＞ 0.05).There was no significant difference in microleakage between iRoot FS group and MTA group (P ＞ 0.05).Conclusion iRoot FS has similar apical sealing ability to MTA and might be considered as a promising root-end filling material.关键词
