Following study selection and data extraction, bibliometric data such as publication years, authors, citation counts, institutions, countries\/regions, journals, and keywords were analyzed using VOSviewer, CiteSpace, SPSS, and Microsoft Excel. A related review was also performed to synthe size key research themes and evolving trends.\r\nResults: 166 publications from 1979 to 2024 met the inclusion criteria, with 50.6% published within the past 5 years. The most cited article received 239 citations. Research originated from 52 countries\/regions, with China contributing the largest number of publications (n=34), followed by the United States (n=26). Wuhan University, the University of Hong Kong, and Texas A&amp;M University were the leading institutional contributors. Journal of Endodontics (JOE) published the most articles (n=38), while International Endodontic Journal (IEJ) accumulated the highest total citations (n=1 666). James L. Gutmann was the most prolific author (n=12), and Bing Fan was the most cited (n=577). Keyword co-occurrence analysis revealed \u201cC-shaped canal\u201d and \u201ccone-beam computed tomography\u201d as the most frequent terms, while \u201cdeep learning\u201d demonstrated a recent and marked citation burst.\r\nConclusion: This study provides an overview of influential studies on C-shaped canal systems in MSMs and identifies key research themes and evolving trends, serving as a reference for future research and clinical practice.<\/jats:p>","DOI":"10.65717\/eej.2026.25144","type":"journal-article","created":{"date-parts":[[2026,3,18]],"date-time":"2026-03-18T10:53:33Z","timestamp":1773831213000},"page":"68-81","source":"Crossref","is-referenced-by-count":0,"title":["C-Shaped Canal Systems in Mandibular Second Molars: A Bibliometric Analysis and Review of Key Research Themes"],"prefix":"10.65717","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-9229-0742","authenticated-orcid":false,"given":"Yuwei","family":"Wang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6022-2911","authenticated-orcid":false,"given":"Ling","family":"Zou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0877-6754","authenticated-orcid":false,"given":"Yuan","family":"Gao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"55248","published-online":{"date-parts":[[2026,2,27]]},"container-title":["European Endodontic Journal"],"original-title":[],"link":[{"URL":"https:\/\/eurendodj.com\/index.php\/pub\/article\/download\/384\/386","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/eurendodj.com\/index.php\/pub\/article\/download\/384\/386","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,3,18]],"date-time":"2026-03-18T10:53:34Z","timestamp":1773831214000},"score":1,"resource":{"primary":{"URL":"https:\/\/eurendodj.com\/index.php\/pub\/article\/view\/384"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,2,27]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2026,2,27]]}},"URL":"https:\/\/doi.org\/10.65717\/eej.2026.25144","relation":{},"ISSN":["2548-0839"],"issn-type":[{"value":"2548-0839","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,2,27]]}}}
