Effect of Different Root Canal Sealers on Postoperative Pain

This randomized clinical trial aimed to evaluate postoperative pain following the use of bioceramic and epoxy resin-based root canal sealers in combination with the continuous wave of condensation technique (CWCT), addressing a clinically relevant gap in the literature. Seventy-two patients with single-rooted teeth diagnosed with asymptomatic irreversible pulpitis and presenting without preoperative pain were randomly assigned to three groups according to the root canal sealer used. The teeth were treated using AH Plus, TotalFill BC, or Bio-C Sealer. All endodontic procedures, including post-endodontic restorations, were completed in a single visit using the continuous wave of condensation technique (CWCT), following standardized preparation and irrigation protocols. Patients were provided with a Visual Analog Scale (VAS) form and were instructed to record their pain intensity on a scale from 0 to 10 at 6, 24, 48, and 72 hours, and 7 days after root canal treatment. Patients were recalled on day 7, and the completed VAS forms were collected. The null hypothesis was that the type of root canal sealer would have no statistically significant effect on postoperative pain levels. The alternative hypothesis was that, regardless of sealer type, the incidence and severity of postoperative pain would be significantly higher within the first 24 hours following treatment compared with the other assessment time points.

The Incidence of Postoperative Pain After Using Different Types of Sealers

The aim of this randomized clinical trial is to evaluate and compare the incidence and intensity of post-operative pain after obturation using resin and silicon-based sealers.
