Aim: This study aimed to evaluate the retrievability of new bio-ceramic material using either single cone technique or cold lateral compaction technique.
Methodology: Thirty recently extracted human permanent mandibular premolars were collected. Samples were randomly distributed among three groups (n=10) based on the obturation technique followed using different sealers; Single Cone Technique/Well-Root ST sealer (SCT/Well-Root ST), Cold Lateral Compaction/Well-Root ST sealer (CLC/Well-Root ST), and Cold Lateral Compaction/AH Plus Sealer (CLC/AH Plus). Following root canal instrumentation and obturation of samples, filling material was retrieved. Retrievability was evaluated in terms of percentage of remaining obturation material, and the mean time required for the retrieval. Samples were longitudinally sectioned into mesial and distal halves. The half containing the greater percentage of remaining obturation material was selected and evaluated using dental operating microscope (DOM) at 16x. Photomicrographs of each third of the canal were captured using digital video camera mounted on the DOM. The percentage of remaining obturation material was evaluated using ImageJ software.
Results: The highest percentage of remaining obturation material and the mean time required was found in SCT/Well-Root ST group, and the lowest percentage was found in the CLC/AH Plus group.
Conclusion: Retrievability of canals obturated using SCT/Well-Root was difficult.
