Global research interest regarding silver diamine fluoride in dentistry: A bibliometric analysis

Abstract

ObjectiveThis study aimed to investigate the global research interest regarding silver diamine fluoride (SDF) in dentistry using a bibliometric approach. MethodsA literature search was conducted in the Web of Science Core Collection database to identify studies related to SDF. Bibliometric data from the selected publications were exported and analysed using the Bibliometrix Biblioshiny R-package software. The type of research and main contents of the publications were summarised. One-way analysis of variance was used to detect the differences in the citation counts of the publications with various types of research. In addition, Google Trends was used to investigate the popularity of the search term “silver diamine fluoride”. ResultsA total of 259 publications were included and analyzed. The annual scientific production of SDF studies increased significantly per year in the past five years, and it mainly concerned dental caries. The three main types of research were laboratory/animal study (n = 114, 44%), review/guideline (n = 56, 22%), and clinical trial (n = 44, 17%). The citation count related to the type of research (p < 0.01). The citation count of clinical trials was significantly higher than that of laboratory/animal studies (p < 0.05). As quantified via data from Google Trends, the search popularity of “silver diamine fluoride” also increased significantly. ConclusionBased on the results of bibliometric analysis, global research interest regarding SDF has rapidly increased in recent years. Clinical significanceThis paper presents an overview of scientific evidence and impact of SDF use in dentistry. SDF attracts a growing interest globally and there has been a steady increase in scientific research into its use in dental practice.
