Abstract
Objectives: 3D evaluation of root canal obturation using different obturation materials and techniques by Micro computed tomography. Material and methods: thirty single root, single canal teeth were selected and used in this study. All canal instrumentations were done by using a Neoflix rotary File according to the manufacturer’s instructions. Then all instrumented canals were divided randomly into 3 groups: group one: 10 canals obturated by AH plus with cold gutta-percha; Group two: 10 canals obturated by AH plus with thermafil; Group three: 10 canals obturated with Guttaflow. All obturated canals were scanned by micro-Ct for measurement of volume percentage of gaps and voids at different levels in the obturated canals by using specialized micro ct software, and then all the collected data were statistically analyzed. Results: Higher percentages of voids and gaps were identified in the coronal third of root canal than in the middle and apical third. Among the obturating materials, the results showed that cold gutta percha obturation had more voids and gaps than other obturating materials with non-significant differences between thermafil and guttaflow. Conclusion: None of the root canal obturating materials were gap-free and root canals obturated with thermafil and guttaflow showed less gaps and voids. A good coronal seal following endodontic treatment is very important for the longevity of the treatment because most of the voids and gaps were located in the coronal third.
