Abstract

Aim: This in vitro study evaluated and compared sealing ability of four different root end filling materials i.e. Glass Ionomer cement, Amalgam, Mineral trioxide aggregate and Bio dentine as a new root-end filling material.  Materials and Methods: sixty extracted human maxillary central incisors were selected. All the roots were instrumented and obturated with gutta-percha and resin sealer. Obturated roots were divided randomly into 6 experimental groups of 10 samples each. In the negative control group (group I), roots were kept without any further preparation. In the positive and experimental groups, roots were apically resected and root-end cavities were prepared and filled with: (a) gutta-percha (group 2-positive control group); (b) amalgam (group 3); (c) IRM (group 4);(d) MTA (group 5); (e) Biodentine (group 6). Apical leakage was assessed using dye penetration technique. Data were submitted to statistical analysis by the one-way analysis of variance (ANOVA) and Tukey’s test.  Results: Significant difference of sealing ability was found among 4 tested groups. Biodentine followed by MTA showed the highest sealing ability, amalgam showing the maximum leakage.  Conclusion: Biodentine with its high sealing ability can be considered a possible root end sealing material.
