Abstract Background: Individuals receiving cancer treatment experience many treatment-related complications. Since one of these complications is oral mucositis, studies are conducted on this subject. This study aims to analyse the studies examining oral mucositis in the pediatric oncology population by bibliometric methods. Methods: Bibliometric analysis was performed using the WosViewer software to scan the articles written in the relevant field. Publication trend, country distribution, journal and citation analysis, citation analysis of publications, keyword analysis of publications, text mining of abstracts were performed. Results: In this study, 108 studies in the Web of Science database were examined. Because of the analyses, it was determined that there was an increase in studies on the subject after 2017. It has been determined that America, Brazil and Canada are the countries with the highest number of studies on this subject. Oral mucositis, mucositis and chemotherapy were determined as the most frequently used keywords. Discussion: Studies of oral mucositis in the pediatric population tend to increase recently. Preserving this increase and accelerating the work to be done in this field will fill the gaps in the literature.
