Aim: To analyze the characteristics of the 100 most-cited papers on Glass Ionomer Cement (GIC) through bibliometric analysis. Methods: A search was performed on November 28th, 2023, using the Web of Science Core and density of citations; year and journal of publication; study design; main topic (objective of the study and type of GIC); authors; institutions; keywords; countries and continents. Scopus and Google Scholar were used to compare the number of citations. Bibliometric networks were generated in VOSviewer. Results: Papers received a total of 15,368 citations, ranging from 84 to 553. The papers were published between 1971 and 2018. The journal that predominated the most was Dental Materials (18%). The majority were laboratory studies (61%), evaluating the procedure performed with GIC (16%). GIC was applied mainly in restorative procedures (79%) the most used type was conventional (50%). The continent with the highest number of publications was Europe (63%), with emphasis on the United Kingdom (23%). The Government Chemist’s Laboratory was the most frequent institution (14%), and Wilson AD had the most publications (13%). Conclusion: The top 100 cited papers primarily originate from Europe and mostly consist of laboratory studies exploring GIC’s clinical performance in restorative dentistry. It’s recommended the development of further interventional studies on GIC, focused on the clinic improvement of the material.
