Top 100 Most-cited Articles in Root Canal Anatomy: A Scopus-based Bibliometric Study

Area of Science:

• Endodontics
• Dental Anatomy
• Bibliometrics

Background:

• Root canal anatomy knowledge is crucial for successful endodontic treatment.
• Bibliometric analysis of top-cited articles identifies research trends and progress in root canal morphology.

Purpose of the Study:

• To identify and analyze the 100 most-cited articles on root canal morphology.
• To discover research trends, influential publications, and methodological progress in the field.

Main Methods:

• Scopus database search for "root canal anatomy" OR "root canal morphology" (excluding "Preparation").
• Inclusion of English-language original research on human teeth, finalized July 28, 2025.
• Analysis of citation counts, publication years, journals, countries, study designs, and methodologies.

Main Results:

• Top articles predominantly published in Journal of Endodontics and International Endodontic Journal (80%).
• Cone-beam computed tomography (CBCT) is the leading methodology, followed by dye-injected decalcified teeth and micro-CT.
• Mandibular and maxillary first molars are most studied; US, Brazil, and China lead publications. Vertucci's 1984 classification remains highly cited.

Conclusions:

• Bibliometric analysis provides a comprehensive overview of influential root canal anatomy studies.
• Insights into global research patterns and technological advancements in the field are offered.
• Identifies a lack of research from Africa, suggesting potential for collaborative development.
