The Comparative Study of Push-out Bond Strength of Two Different Root Canal Sealers with Cold Lateral Condensation Obturation Technique - Invitro Study

Abstract

Aim: To evaluate and compare the pushout bond strength of BioCeramic sealer and AH plus sealer using Gutta percha with cold lateral compaction technique. Material and Methodology: Forty-five human extracted single rooted teeth Mandibular 1st premolar teeth with completely formed apices were selected, instrumentation were done by using Protaper Next rotary system using X1, X2 and X3. The teeth were divided into three groups based upon the sealer used Group 1: Bioceramic sealer (CeraFill RCSTM), Group 2: Epoxy resin-based sealer (AH Plus sealer), and Group 3: Obturated using Gutta percha only using cold lateral compaction technique and stored for 4 week. After ob-turation, each tooth was prepared for push-out bond strength test with root slices of 2mm thickness using universal testing machine. Results: The highest bond strength was found in Group1 Bioceramic sealer (CeraFill RCSTM) (P < 0.05) compare to other groups. Statistical analysis is done by ANOVA, Student't' test. Conclusion: The push-out bond strength of Bioceramic sealer was highest followed by resin based sealer and lowest bond strength was observed in Group 3
