RESUMO
Aim: To evaluate and compare three different root canal sealers (Endo-Sequence BC, Bio Root RCS and Zinc Oxide Eugenol) on post operative pain in single visit root canal therapies. Material and Methodology: 60 subjects with age ranging from 18-60 years were randomly selected depending upon the inclusion criteria. The subjects were then divided into three groups with 20 patients in each. In all the patients' single visit root canal treatment was done followed by obturation using different sealers. In Group I Endo- Sequence sealer was used, in Group II Bio-Root RCS and in Group III Zinc Oxide Eugenol sealers were used respectively. Results: statistically significant results were obtained on comparing the efficacy of three groups with Group I proving to be much effect among the three. Conclusion: within the limitation of the study it can be concluded that though all the sealers were effective in reducing post-operative pain, patients with Endo Sequence BC sealers evaluated statistically significant results.
