Comparing Obturation Using Bioceramic Nano-coated Gutta-percha With Bioceramic Sealer Versus Traditional Gutta-percha With Resin Sealer for Reducing Postoperative Pain and Swelling After Root Canal Treatment in Necrotic Single-rooted Teeth.

This randomized clinical study aims to compare the clinical and radiographic outcomes of root canal obturation using a bioceramic sealer with bioceramic-coated gutta-percha versus conventional obturation using a resin-based sealer with conventional gutta-percha. The study will be conducted on patients requiring endodontic treatment according to the established inclusion and exclusion criteria.

Participants will be randomly allocated into two groups. The control group will receive obturation using conventional gutta-percha with a resin-based sealer, while the experimental group will receive obturation using bioceramic-coated gutta-percha with a bioceramic sealer. Standardized endodontic treatment procedures will be performed for all participants.

Clinical and radiographic evaluations will be carried out during the follow-up period to assess treatment success, postoperative pain, postoperative swelling, and obturation quality. The outcomes of this study may help determine the effectiveness and clinical performance of bioceramic obturation materials compared with conventional obturation techniques in endodontic therapy.
