Aim: The purpose of this study was to evaluate and compare the dentinal wall adaptation ability of two recently introduced silicate-based root canal sealer

Materials and Methods: 24 extracted human maxillary single rooted teeth with intact roots were selected. The crown portion removed followed by canal preparation up to F3 PTG. The teeth were then randomly divided into two groups and dentinal wall adaptation ability was studied under stereomicroscope.

Results: The statistical analysis showed no significant difference between two sealers in terms of gap formation (P > 0.05). Both the groups at some level or the other exhibited some degree of gap formation.

Conclusion: Bioceramic sealer Hiflow has a similar dentinal wall adaptation ability as Endosequence MTA
