Abstrakt:	Aim: The aim of this study was to evaluate the homogeneity and quality of different obturating systems using cone-beam computed tomography (CBCT). Materials and Methods: One hundred and twenty extracted maxillary and mandibular molars were included in this study which was decoronated first and then dissected into palatal and distal roots. After working length determination, all the roots were biomechanically prepared with ProTaper universal system. The prepared roots were evaluated using CBCT, and volumetric analysis was done. Samples were then randomly divided into three groups corresponding to the obturation method used - cold lateral compaction technique, single-cone technique, and BeeFill 2 in 1 system. After obturation, CBCT imaging and volumetric analyses were performed again to compare and analyze the amount of volume of obturation in different obturating techniques. To standardize the volume, pre-and postobturation images were superimposed. To avoid errors, for each section, measurements were repeated three times and the means were calculated. Statistical Analysis Used: The data were statistically analyzed using one-way analysis of variance, followed by post hoc test. Results: Results showed a statistically significant difference of the single cone with lateral compaction and the BeeFill system ( P < 0.001). Maximum volume of obturating material was found in BeeFill at all levels - Coronal, middle, and apical, followed by cold lateral compaction and single-cone technique ( P < 0.001). Conclusion: It could be concluded that the thermoplasticized obturating technique can be a better choice for obturation rather than the single cone and lateral compaction technique. Competing Interests: There are no conflicts of interest. (Copyright: © 2023 Journal of Conservative Dentistry and Endodontics.)
