The participants were randomly divided into two treatment groups: Group 1 underwent SV therapy, while Group 2 received MV therapy. In the MV group, calcium hydroxide was introduced as an intracanal dressing following the preparation phase, and the root canal obturation was performed in a subsequent session after 1 week. In the SV group, obturation was completed in the same session. For the MV group, calcium hydroxide was removed during the second visit, the irrigation procedure was repeated, and obturation was finalized. Pain levels were measured postoperatively using a visual analog scale (VAS). Participants documented their pain at 6 and 12\u2009h following treatment, as well as daily for the next 2 days. In the MV group, pain was additionally evaluated at the beginning of the second session, and patients were asked to report any pain experienced during the interval between visits. Follow\u2010up appointments were conducted to assess the progress of sinus tract healing, which was defined as the complete closure or resolution of the tract over a 14\u2010day period. Data were analyzed using the two\u2010sample proportion test and Pearson\u2019s chi\u2010square test, with statistical significance set at\n                    <jats:italic>\u03b1<\/jats:italic>\n                    \u2009=\u20090.05.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:<\/jats:bold>\n                    The findings indicated no statistically significant differences between the two groups regarding the frequency of postoperative pain (\n                    <jats:italic>p<\/jats:italic>\n                    &gt; 0.05). Median scores showed that VAS scores were highest after 6\u2009h (Mdn\u2009=\u20093, IQR\u2009=\u20095.25), followed by 12\u2009h (Mdn\u2009=\u20093, IQR\u2009=\u20096), after 24\u2009h (Mdn\u2009=\u20090, IQR\u2009=\u20093.25), and after 48\u2009h (Mdn\u2009=\u20090, IQR\u2009=\u20093). In both groups, pain levels at the 6\n                    <jats:sup>th<\/jats:sup>\n                    h were found to be higher than at the 48\n                    <jats:sup>th<\/jats:sup>\n                    h (\n                    <jats:italic>p<\/jats:italic>\n                    &lt; 0.05). Mean recovery time was 6.8 days for the SV group and 6.56 days for the MV group. The duration required for sinus tract healing showed no significant variation between the SV and MV treatment modalities (\n                    <jats:italic>p<\/jats:italic>\n                    &gt; 0.05).\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusion:<\/jats:bold>\n                    Both SV and MV root canal treatments (RCTs) yielded comparable outcomes in terms of postoperative pain levels and the time necessary for sinus tract resolution, with no statistically significant differences observed between the two approaches. The observed similarity in healing parameters and pain levels suggests that both treatment methods demonstrate comparable clinical effectiveness.\n                  <\/jats:p>","DOI":"10.1155\/ijod\/4200682","type":"journal-article","created":{"date-parts":[[2025,7,17]],"date-time":"2025-07-17T17:33:32Z","timestamp":1752773612000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Comparison of the Effectiveness of Single\u2010Visit and Multi\u2010Visit Root Canal Treatment on Healing Intraoral Sinus Tract"],"prefix":"10.1155","volume":"2025","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2956-729X","authenticated-orcid":false,"given":"Fatma Beg\u00fcm","family":"Peker","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0896-777X","authenticated-orcid":false,"given":"Mehmet Burak","family":"G\u00fcne\u015fer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,7,17]]},"reference":[{"key":"e_1_2_12_1_2","doi-asserted-by":"publisher","DOI":"10.1016\/0030-4220(65)90166-0"},{"key":"e_1_2_12_2_2","unstructured":"SundqvistG.
