The aim of this study was to investigate the effect of different irrigants (EDTA,
MTAD, CHX) on the sealing ability of new Bioceramic root canal sealer. Material
and methods: A total of sixty extracted human single-rooted premolar teeth were
used. After instrumentation, teeth were randomly divided into three main groups
(n=20) according to the type of final irrigants used. In group (A) 17% EDTA was
used. Group (B) irrigants was MTAD. In group (C) irrigant was 2% CHX. Each main
group further subdivided into two subgroup (n=10) according to the type of sealer
used. Subgroup (1) canals obturated with Bioceramic sealer. In subgroup (2) canals
obturated with AH plus sealer. After incubation period for one week the roots were
placed in 2% methylene blue dye and kept in incubator for 48 hours then the roots
were cleared, dye penetration measured by stereomicroscopic. Results: statistical
significant difference was found between groups (p<0.001). In subgroup (1) BC sealer
& CHX showed the lowest mean of leakage in comparing to other type of irrigants
with highly significance difference with BC sealer & EDTA. In subgroup (2) AH Plus
& EDTA showed the lowest mean of apical leakage. A highly significance differences
was found between subgroup (1) and subgroup (2) for all type of irrigants.
(p<0.001).Conclusion: when Bioceramic sealer is used in obturation of root canal
system, it is better to use it in combination with CHX irrigant to improve the apical
