Objective: To conduct a bibliometric analysis of the literature on C-shaped canal systems in mandibular second molars (MSMs) and to review key research themes and evolving trends. Methods: A comprehensive search of the Web of Science Core Collection (WoS-CC) was conducted for publications through 31 December 2024. 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. Results: 166 publications from 1979 to 2024 met the inclusion criteria. Conclusion: 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.
