Aim: The “Giornale italiano di Endodonzia” (GIE) is a peer-reviewed journal founded in 1987. It is the official journal of the Italian Society of Endodontics (SIE) and it is currently indexed in Scopus and Embase. In order to offer a comprehensive evaluation of the scientific journal production, we carried out a bibliometric analysis of the articles published on GIE.

Methodology: We searched the journal website archive for the non-indexed articles and Scopus for the indexed articles published until March 2022. Relevant data were extracted from each article. Bibliometric analysis was performed using Biblioshiny, Publish and Perish and VOSviewer.

Results: A total of 601 documents were found, 246 (41%) of them were indexed in electronic databases. The annual production ranges from 4 (1987) to 37 (2021) with a mean annual growth rate of 6,76%.

The most frequent keywords were “endodontics”, “MTA”, “CBCT”, “cyclic fatigue” and “root canal treatment”.

Conclusions: Bibliometric studies involve a rigorous process of analysis and classification of large volumes of bibliographic material to evaluate the impact of scientific publications, highlight the trend of topics of interest and map the relationships between documents, articles, affiliations and nations. GIE has seen the scientific production and the number of citations growing over the years. Some articles published on GIE had a moderate impact on the international literature. Alongside classic topics of interest, new "hot topics" have emerged regarding innovative materials and technologies.
