Effectiveness of silver diamine fluoride (SDF) in arresting coronal dental caries in children and adolescents: a systematic review

Abstract

Dental caries remains a significant public health issue for children globally, leading to adverse effects on health and development. Silver diamine fluoride (SDF) is a potential preventive agent that can prevent caries progression in children. This systematic review examined the effectiveness of silver diamine fluoride in arresting caries compared to other fluorides. An electronic search of MEDLINE, PubMed, EMBASE, Cochrane, Web of Science, Scopus databases was carried out examining articles in English from 2001 to 2023. Studies included in the analysis examined the application of SDF in children and adolescents with coronal caries lesions on primary teeth or permanent first molars. Fifteen studies, involving a total of 7895 children, were incorporated. The application regimen varied across studies. Most studies in this review consistently suggested that SDF is effective in arresting caries. An annual application of SDF effectively reduced Streptococcus mutans count. Adverse effects were primarily tooth staining and less commonly, oral mucosal irritation. A majority of studies showed a high risk of bias due to methodological insufficiencies. Overall, the evidence suggests that SDF is effective in arresting dental caries in children. It offers a viable, cost-effective, and minimally invasive treatment option, particularly suitable for use in low-resource settings. However, the aesthetic concern of tooth staining with SDF use remains a challenge. Further well-designed clinical trials may provide a fuller picture of SDF which can shape public health policy and shift towards a minimally invasive treatment approach.
