Abstract
Aim: The aim was to study the sealing efficacy of polydimethylsiloxane‑based root canal sealers.
Materials and Methods: Polydimethylsiloxane‑based root canal sealers were reviewed and
subjected to an ex vivo study. A total of 60 extracted maxillary incisors were included in this
study, which was conducted under two groups, Groups A and B, of 30 teeth each. In Group A,
GuttaFlow and in Group B, RoekoSeal as sealers were used for obturation with Gutta‑percha
cones after preparing canal with a step back technique. The criterion for evaluating sealing
efficacy of the sealers was light absorption by spectrophotometer. The collected data were
analyzed statistically using one‑way ANOVA test.
Results: The findings of the study revealed that the mean leakage in Group B (0.1027) was
significantly less than Group A (0.1649) (P < 0.001). RoekoSeal showed superior sealing ability.
Conclusion: RoekoSeal had the better sealing ability than GuttaFlow and may be recommended
for clinical use.
