Abstract

Introduction: This study compared in vitro the coronal sealing ability of four types of endodontic sealers One-Fil, ADSEAL, GuttaFlow Bioseal, BioRoot RCS
Materials and Methods: Thirty-two single-rooted mandibular premolars were randomly divided into 4 groups (n=8). After Instrumentation, each group obturated using a different type of sealer as group 1: One-Fil, group 2 ADSEAL, group 3: GuttaFlow Bioseal, and group 4: BioRoot RCS. Teeth were cleared then subjected to a dye penetration test, then evaluated under stereomicroscope.
Results: Kruskal-Wallis test was used to compare dye penetration depth among the different endodontic sealers. Post-hoc analysis was conducted using Dunn’s multiple comparison test. The mean score of dye penetration could be arranged from the least to the greatest as follows: One-Fil (1.38 ± 0.52) followed by ADSEAL (2.38 ± 0.52) without significant difference between them, however One-Fil recorded lower significant dye penetration compared to GuttaFlow Bioseal (2.5 ± 0.53) and BioRoot RCS which showed the highest mean of dye penetration (2.75 ± 0.46).
Conclusions: Premixed calcium silicate sealer revealed the highest significant resistance against dye penetration while hand mixed calcium silicate sealer revealed the least resistance against coronal dye penetration.
Clinical Relevance: All types of the investigated sealers allowed dye penetration with variable degrees, therefore, proper coronal and apical sealing with adequate final restoration is the key to successful treatment outcome.
