Abstract

Objective: An endodontic sealer contributes in obtaining an appropriate seal for the root canal system by establishing an association between the root canal walls and coronal restoration thereby promoting healing. This present research intended to compare the penetrating capacity and to determine sealer/dentin interface among various endodontic sealers.
Materials and Methods: Horizontally sectioned tooth samples were obtained at 3 and 5mm and randomly divided into three groups: Group I - Chemically cured (AH Plus) sealer; Group II - Dual cured (EndoREZ) sealer; Group III – BioCeramic Nano sealer (iRoot SP). All three groups were coated with their respective sealers and obturated using cold lateral compaction technique. The samples were observed using Confocal Microscope for penetrating capacity evaluation and reviewing of sealer/dentin junction at 3 and 5mm depth. The results were statistically analyzed using one-way ANOVA and Tukey's Post-Hoc method.
Results: On depth of penetration evaluation, one-way ANOVA analysis showed Group II exhibited maximum depth of penetration in contrast to Group III and Group I. Group I showed the least average depth of penetration among the other two groups at both 3 and 5mm. On sealer/dentin interface evaluation at 3mm, Group II showed increased interface in comparison with to Group III and Group I. No statistical significance evident among the groups at 5mm.
Conclusion: EndoREZ showed maximum depth of penetration in comparison with iRoot SP and AH Plus sealer at both 3 and 5mm. EndoREZ also showed significant sealer/dentin interface at the level of 3mm when compared to other sealers used.
