Methods. Seventy patients were contributed in the trial. A total of 64 eligible patients were randomized into four equal groups (n=16 per group). Considering the irrigation activation approach, participants were separated into four groups as follows: Group 1: passive ultrasonic irrigation. Group 2: XP-endo Finisher. Group 3: Fanta AF max file Group 4: Manual dynamic agitation. Following the root canal procedure, the intensity of postoperative discomfort was measured by a verbal rating scale. The frequency and quantity of analgesics used were recorded. Results. Using an analysis of variance (ANOVA), there was a statistically significant difference between the percentage of preoperative and postoperative pain at most of the follow-up period (p<\/jats:p>","DOI":"10.14744\/eej.2025.75547","type":"journal-article","created":{"date-parts":[[2025,7,17]],"date-time":"2025-07-17T08:08:57Z","timestamp":1752739737000},"page":"285-295","source":"Crossref","is-referenced-by-count":0,"title":["The Impact of Different Final Irrigation Activation Techniques on Postoperative Pain in Single Rooted Mandibular Premolar Teeth: Randomised Clinical Trial"],"prefix":"10.65717","volume":"10","author":[{"given":"Yasmin Tawfik Mohamed","family":"Sobh","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mai Hamdy","family":"Ragab","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"55248","published-online":{"date-parts":[[2025,7,16]]},"container-title":["European Endodontic Journal"],"original-title":[],"link":[{"URL":"https:\/\/www.eurendodj.com\/index.php\/pub\/article\/download\/345\/345","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.eurendodj.com\/index.php\/pub\/article\/download\/345\/345","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,1,22]],"date-time":"2026-01-22T12:17:00Z","timestamp":1769084220000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.eurendodj.com\/index.php\/pub\/article\/view\/345"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,7,16]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2025,7,16]]}},"URL":"https:\/\/doi.org\/10.14744\/eej.2025.75547","relation":{},"ISSN":["2548-0839"],"issn-type":[{"value":"2548-0839","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,7,16]]}}}
