Abstract

Introduction: Bioactive endodontic sealers have been developed to improve the quality of root canal obturation. Endo Sequence BIOCERAMIC (BC) Sealer is amongst calcium silicate based materials recently developed for permanent root canal filling. The objective of this study was to evaluate the BIOACTIVITY of BC Sealer and its MICRO PUSH-OUT BOND STRENGTH to dentin compared to AH-Plus (AH) sealer.Methods and Materials: To perform the micro push-out test, 24 root canals of mandibular premolars were instrumented and divided into two groups (n=12). Each root was cut into 4 slices and lumens of the canals were filled with the sealers and submitted to micro push-out test. Failure mode was assessed using scanning electron microscopy (SEM). BIOACTIVITY of BC sealer was investigated with scanning electron microscopy/energy-dispersive X-ray (SEM/EDS) and X-ray diffraction (XRD). BIOACTIVITY assessments were reported descriptively. Bond strength data were analyzed by parametric test (a=5%).Results: In micro push-out test AH had higher bond strength mean values (16.29 MPa) than BC sealer (9.48 MPa) (P<0.05). Both groups had low amount of adhesive failure. SEM showed the presence of a mineral precipitate after 30 days and EDS analysis showed that those precipitates have high proportion of Ca. XRD showed peaks of crystalline phases of calcium carbonate compatible with the BIOACTIVITY.Conclusion: BC sealer showed indications of BIOACTIVITY and lower bond strength to DENTINE compared to AH.
