Özet

This study is aimed to evaluate the compatibility of single-cone filling technique in reciprocal

and rotationally formed canals in using Micro-CT (Micro-computed tomography). The samples were

split into two groups according to the kinematics system used. In both groups, one canal of the shaped

roots was filled with the lateral compaction and the other one with a matched single-cone technique

with a bioceramic root canal sealer, BioRoot RCS. The percentage of voids in the canal were evaluated

by micro-CT radiograph before and after obturation. Regardless of the kinematics used, the single-cone

technique left significantly fewer voids than the lateral compaction. In the kinematics comparison, the

group shaped with the reciprocal system and filled with the single-cone system had the best results. The

reciprocal nickel-titanium (NiTi) system with a matching single-cone gutta percha filling technique was

found to be more effective in terms of reducing voids in root canal filling.
