Abstract: Objective: To evaluate the effects on the apical sealing ability of iRoot SP used for straight root canals. Methods: 73 extracted human teeth with straight roots were randomly assigned to 8 groups. The root canals in groups A3 was obturated with single gutta-percha cone. The others were obturated with thermoplasticized gutta-percha cones. The canals were filled with AH Plus (group A1 and B1), iRoot SP (group A2, A3 and B2) and ZOE (group A4) . The post space was prepared either immediately after obturation (A1-A4) or 7 days later group (B1 and B2) . The extent of dye penetration was measured by transparent dental technology. Results:There were no significant differences among A1-A3 groups, between group A1 and B1, A2 and B2, P＞ 0. 05. The dye penetration extent of group A4 and C was greater than that of group A2 (P ＜ 0. 05) . Conclusion: iRoot SP and AH Plus have same performance on root canal seal. There was no significant difference between iRoot SP + thermoplasticized gutta-percha and iRoot SP + single gutta-percha cone for apical sealing.
