| Abstract | ||
| Aim: The aim of this in vitro study was to compare XP-endo shaper, XP-endo finisher, and Passive Ultrasonic Irrigation sealer removability of two root canal sealers (resin and bioceramic based) in internal root resorption simulated teeth. Methodology: 132 extracted human mandibular premolars were prepared and split, artificial cavities were placed on both teeth segments 5 mm from root apex then teeth segments were brought back together and fixed in epoxy resin model. Models were randomly assigned to six groups (n=22) according to the root canal filling and retreatment protocol. Group 1: (BC sealer and retreated using XP-endo Finisher). Group 2: (Resin sealer and retreated using XP-endo Finisher). Group 3: (BC sealer and retreated using XP-endo Shaper). Group 4: (Resin sealer and retreated using XP-endo Shaper). Group 5: (BC sealer and retreated using PUI). Group 6: (Resin sealer and retreated using PUI). Samples were split again to evaluate sealer removability under digital light microscope. Results: There was a significant difference between the 6 groups in the sealer removability Van der Sluis score (p = 0.013). Group 5 showed the highest score followed by groups 1, 2, 4 and 6 with no significant difference between them. Group 3 showed a significantly lower score than group 5. There was no significant difference between group 3 and groups 1, 2, 4 and 6. Conclusion: No treatment protocol was able to eliminate all sealer remnant effectively. Resin based sealer showed no significant difference when compared to Bioceramic based sealer when it comes to sealer removability. | ||
