Abstract

Introduction: Single cone technique and bioceramic sealers are highly anticipating recently in root canal treatment, yet their retreatability still controversial. Aim: To assess the cleanliness of the root canal walls after Chemico-mechanical removal of the guttapercha obturated with different techniques; cold lateral condensation and single cone effect of different obturation techniques with or without solvent. Methodology: Thirty-two recently extracted human permanent mandibular premolars with single canal were collected. Samples were randomly distributed among two groups (n=16) based on the obturation technique followed using bioceramic sealers; Cold Lateral Compaction/ceraseal sealer and Single Cone Technique/Ceraseal. Each group was further subdivided into two subgroups according to using of solvent (n=8), Then retreatment of samples done. Retrievability was evaluated in terms of remaining obturation material percentage using the stereomicroscope and Imagej software. The percentage of opened dentinal tubules inside the canal was evaluated using SEM. Results: The highest mean percentage of the remaining guttapercha was found in the single without solvent group while lateral without solvent group achieved the lowest one, moreover the lateral condensation without solvent group achieved the highest mean of percentage of open dentinal tubules while single without solvent group achieved the lowest one. Conclusion: presence of solvent and bioceramic sealer result in more blockage of dentinal tubules and difficulty to achieve optimum canal cleanliness.
