Abstract
Aim
To analyze the efficacy of various heat-treated retreatment file systems on the apical deformity and canal centering ability in single-rooted teeth using nano CT.
Materials and Methods
A total of 45 single-rooted teeth were decoronated to 18mm and obturated. Three retreatment file systems were used, such as: Group 1- Solite RS3 Retreatment, Group 2- Solite RS3 Black Retreatment, and Group 3 - Solite RE Black Retreatment. All these procedures were carried out by a single operator. Nano-Computed tomography (CT) scans, pre- and post-operative, were obtained and superimposed for analysis. One-way ANOVA and post hoc tests were done to test the significance between the three groups.
Results
Based on the results, it was inferred that the Solite RE Black file system had better canal centering ratio and less apical deformity during the retreatment compared to Solite RS3 and Solite RS3 Black (p<0.05).
Conclusion
Solite RE Black file systems had superior centering ability in all apical thirds and less transportation in the middle and coronal thirds when compared to the other two retreatment file systems.
