Background: This study aimed to evaluate the efficiency of different techniques in removing Gutta-Percha (GP) and iRoot SP^® sealer in a long-oval shaped canal using micro-Computed Tomography (micro-CT).

Materials and methods: Forty-eight single-rooted mandibular premolars with single long oval straight canals were prepared using ProTaper Next^® to size X3 (30/.06) and filled with GP and iRoot SP^® using the hydraulic technique 2 mm short of the Working Length (WL). The sample was randomly divided into four groups (n=12) based on removal technique: Group 1: Pro Taper^® Universal Retreatment system (PTU Rx); Group 2: PTU Rx with Xylol; Group 3: PTU Rx with Endo Success™ Retreatment Kit, ET25 tip and Group 4: PTU Rx with Xylol and ET25 tip of Endo Success™ Retreatment Kit. All specimens scanned before and after the removal of the root canal filling material using a micro-CT system to assess the remnant of root filling materials. The data analysed using one-way Analysis of Variance (ANOVA), Student-Newman Keuls post hoc test for remaining root filling material and Pearson chi-square test for regaining patency (p=0.05).

Results: Results showed no statistically significant difference in the remaining root filling material between groups (p>0.05). The apical thirds showed the highest percentage of the remaining root canal filling material compared to the middle and coronal thirds (p<0.01). Results showed no statistically significant difference in the ability to achieve patency between groups (p>0.05).

Conclusion: No technique proved to be superior to others in removing bioceramic root filling-based material from long oval canals. Bioceramic sealers are negotiable in single, straight root canal anatomy.
