ABSTRACT
AIM: Apical leakage is one of the drawbacks leading to endodontic failure. Various root canal sealants have been tried in endodontics. The present study was conducted to compare root canal sealants such as Endorez, Realseal, and Metaseal in preventing apical leakage. MATERIALS AND METHODS: Sixty mandibular single-canal premolars were divided into three groups of 20 each. Group I teeth were sealed with Endorez, group II teeth with Realseal, and group III teeth with Metaseal. After completing endodontic treatment in all teeth and sealing with above sealants, glucose leakage value was assessed at 1st, 8th, and 15th day. RESULTS: At day 1 [mean ± standard deviation (SD)], leakage was 0.416 ± 0.011 in group I, 0.234 ± 0.09 in group II, and 0.328 ± 0.19 in group III. On 8th day, it was 2.124 ± 0.108 in group I, 0.624 ± 0.102 in group II, and 1.31 ± 0.24 in group III. On 15th day, it was 5.178 ± 0.125 in group I, 3.122 ± 0.150 in group II, and 4.25 ± 0.28 in group III. The mean apical leakage in all groups in different days was statistically significant (p < 0.05). CONCLUSION: Endorez sealant showed highest apical leakage, whereas Realseal had minimum leakage. There was significant increase in leakage in all groups with the progression of time. CLINICAL SIGNIFICANCE: With the advent of different root canal sealants, the success rate of the root canal-treated teeth can be confirmed.
