Pain is unwanted but common sensation after root canal treatment. Studies have shown that endodontic postoperative pain between 3 to 58%. Pain may occur in periodontal tissues after mechanical, chemical and microbial injuries. There are various parameters in treatment that can cause postoperative pain. one of these parameters is including working length. Also, the number of visits, selection of instruments and the selection of root canal sealers. Aim of the Study: To compare the potential

... s of resin-based and bioceramic sealers on the occurrence and intensity of postoperative pain in patients with asymptomatic apical periodontitis. Methods: Sixty eight patients with asymptomatic apical periodontitis multirooted teeth were included. After confirming the diagnosis clinically and radiographically, patients were randomly assigned into two equal groups of 34 patients each. Standard endodontic treatment was performed in single visit. During the obturation the patients in the intervention group were treated using Endosequence BC sealer; while AH Plus sealer was used during obturation in patients assigned to the comparator group. Assessment was done 6, 12, 24, 48, 72 hours and 5 days postoperatively. Visual Analogue Scale (VAS) was used in the outcome measurement. Contact with the patients was done over the phone at each follow up time as a reminder for the patients and an appointment was scheduled to receive the chart. Then data was statistically analyzed. Results: Results showed that there was no statistically significant difference between the two sealers groups: AH Plus sealers and Endosequence BC sealer regarding intensity of postoperative pain at 6 hours, 12 hours, 24 hours, 48 hours, 72 hours and 5 days. Conclusion: Post endodontic pain in the teeth diagnosed with asymptomatic apical periodontitis (AAP) and obturated with resin based or bioceramic root canal sealers without extrusion beyond the apex was low. No differences were observed at 6, 12, 24, 48, 72 hours and 5 days post obturation. This means that resin-based and bioceramic root canal sealers act the same in incidence and postoperative pain severity.
