Abstract
Background: Postoperative pain in endodontic treatment is influenced by various factors, including obturation techniques and choice of sealers. Bioceramic sealers have shown advantages over epoxy-resin sealers in terms of reduced postoperative pain. Ultrasonic activation combined with bioceramic sealers may contribute to further reduction in postoperative pain, warranting further investigation.
Methods: This study aimed to evaluate the effect of ultrasonic activation on the incidence of postoperative pain in root canals obturated using two different types of root canal sealers: epoxy-resin based and bioceramic based. Thirty patients with vital pulps were randomly assigned to each obturation technique. Pain intensity was measured using a Visual Analog Scale (VAS) over a period of seven days postoperatively. Statistical analysis was performed using Mann–Whitney U test for between group comparison.
Results: The bioceramic sealer group showed significantly lower pain intensity on the first and second days postoperatively compared to the epoxy-resin sealer group (p < 0.05). However, by the third day and beyond, there was no significant difference in pain levels between the two groups.
Conclusion: The combination of ultrasonic activation and bioceramic sealers may be more effective in reducing short-term postoperative pain compared to epoxy-resin sealers. The choice of sealer material and irrigation technique can play an important role in minimizing discomfort for patients rehabilitated with tooth supported overdentures. Further research with larger sample sizes is recommended to confirm these results.
