Abstract

Aims: To evaluate and compare the push-out bond strength of root filled with Endosequence BC, AH Plus and Endomethasone N sealers using lateral condensation and thermoplasticized technique.

Materials And Methods: Thirty mandibular premolars with completely formed roots were selected. Teeth were decoronated, working length was determined. Instrumentation and irrigation were performed. Teeth were then obturated with Group 1-Cold lateral compaction (n = 15) or Group 2-Thermoplasticized technique (n = 15). Each group was again subdivided into three depending on the sealers used. Teeth in each subgroup were then sectioned perpendicularly to the long axis to obtain a disc of 2 mm each, which were then subjected to micro push-out test. Data was analyzed with ANOVA.

Results: AH Plus sealer in Group 1 showed the maximum (4.77 ± 1.67 MPa) push-out bond strength among the three sealers and between two groups. The mean strength of Bioceramic sealer was lower in Group 1 (2.62 ± 0.76 MPa) and higher in Group 2 (3.52 ± 0.69 MPa).

Conclusions: The push-out bond strength of Endosequence BC sealer was lower than the AH Plus root canal sealer with cold lateral condensation technique.
