AIM: To evaluate the root filling quality of two different sealers using thermoplasticised obturation technique in an artificial internal resorption cavity. METHOD: For this study, 20 mandibular central incisors with single canal were selected. After the biomechanical preparation, the roots were sectioned 7mm from apex. The internal resorption cavities were created on both the parts of sectioned root and then again approximated together. According to the sealer used, the teeth were divided into two groups with 10 teeth in each group and obturation was carried out using thermoplasticised injection technique. To check the obturation mesio-distal and bucco-lingual views were taken on radiograph and then after 7 days the sectioned roots were viewed and photographed under microscope for percentage evaluation of sealer, gutta percha and voids. The statistical analysis was performed using one way ANOVA test. RESULTS: The MTA Fillapex group showed better filling ability with greater filling area and less number of voids than the CeraSeal group. CONCLUSION: MTA fillapex group showed superior results than the CeraSeal group.
