The purpose of the present study was to compare the clinical outcome of Mineral trioxide aggregate (MTA) as a root canal sealer with that of Zinc oxide eugenol sealer for obturation of nonvital teeth with periapical lesion. A total of 50 nonvital teeth with periapical lesion were randomly divided into 2 groups of 25 teeth in each group and treated as follows: Group-I: obturated with Zinc oxide eugenol sealer. Group II: obturated with MTA based sealer (MTA fillapex). Patients were recalled after 3, 6 and 12 months interval. Clinical outcome was evaluated by assessing tenderness on percussion and radiological evaluation was done to determine periodontal ligament widening . Chi-square test and unpaired student t-test were used for testing differences between the two groups and a value of p <0.05 was considered as statistically significant. It was found that at 6 and 12 months, the periodontal ligament widening were reduced in MTA fillapex, which was statistically significant than that of Zinc oxide eugenol sealer (p<0.05). It can be concluded that MTA based sealer is more effective than Zinc oxide eugenol sealer in respect to periapical healing.
