Tricalcium Silicate Endodontic Cements: A Bibliometric Analysis of the 100 Most Cited Articles

Bibliometric analysis is an indicator of high-quality evidence for the decision-making process regarding the use of biomaterials. The aim of this study was to analyze the characteristics of the 100 most cited articles on tricalcium silicate endodontic cements.

A broad search strategy using key terms related to hydraulic endodontic cement was conducted in the Web of Science - Core Collection (WoS-CC) on May 30, 2025. Data were retrieved and organized in descending order of the number of citations in the WoS-CC, and each article was compared with the number of citations in the Scopus and Google Scholar databases. VOSviewer software (Leiden University, The Netherlands) was used to construct co-authorship networks. Spearman's correlations were performed using the Statistical Package for Social Sciences (SPSS 22.0, Armonk, NY).

The most cited article was "Physical and chemical properties of a new root-end filling material," by Torabinejad et al. (1995), with 821 citations in WoS-CC. Of the 100 articles, the corresponding authors were predominantly from the United States (n = 37). The institution of origin of most articles was Loma Linda University (USA) (n = 15). Experimental laboratory studies were the most common study design among the included articles (58%), followed by literature reviews (14%) and observational studies (11%). The mineral trioxide aggregate (MTA), whether ProRoot MTA or MTA Angelus, was the predominant studied material (21,84%) and most studies focused on the evaluation of material properties (48%).

This list of the most cited articles can provide a reference point to guide research and biomaterial selection.
