				        	Objective To evaluate and compare the impact of three root canal sealers(C-Root SP,iRoot SP,and AH-Plus Jet)on the sealing performance in single-cone root canal filling using micro-computed tomography(Micro-CT).Methods Ninety mandibular single-rooted extracted teeth meeting inclusion criteria were collected,prepared with Protaper Next up to X3,and randomly assigned to three experimental groups which were C-Root SP group(Group A),iRoot SP group(Group B),and AH-Plus Jet group(Group C).Subsequently,all three groups underwent single-cone root canal filling,followed by one week of oral environment simulation.The seal-ing performance of the three root canal sealers was evaluated by measuring the proportion of the root canal volume and its rate using Mi-cro-CT.Results In different segments of the roots(upper 1/3,middle,and lower),identifiable bubbles were observed in the Group A,Group B and Group C,with volumes of(0.15±0.03)mm3,(0.22±0.11)mm3,and(0.34±0.28)mm3,respectively.Overall,Group A exhibited the smallest bubble volume(0.15±0.03)mm3.Group A and B were similar,they were superior to group C.(P<0.05)Nevertheless,in the apical 1/3 segment(0-3 mm),a significant statistical difference was observed between the bubble volumes of Group A(0.01±0.01)mm3 and Group C(0.12±0.08)mm3(P<0.05),while no significant difference was observed compared to Group B.Conclusion The apical sealing performance of C-Root SP is similar to iRoot SP and superior to AH-Plus Jet.C-Root SP can be considered as a favorable choice for root canal sealer.
