Silver Diamine Fluoride in Pediatric Dentistry: Effectiveness in Preventing and Arresting Dental Caries—A Systematic Review

Background: Tooth decay is considered a global scourge by the World Health Organization (WHO) starting at an early age. In recent years, silver diamine fluoride (SDF) has regained interest, particularly in pediatric dentistry, used to prevent the development of carious lesions or arrest their progression. Objective: The aim of this study was to assess, through a systematic review of the literature, the effectiveness of SDF, used in pedodontics, in temporary teeth, in preventing or arresting dental caries. Material and Methods: An electronic search was conducted on PubMed, Web of Science and Scopus. The effect of SDF on both temporary and permanent teeth has been considered. Results: The inclusion criteria identified 16 randomized controlled trials involving patients aged 18 months to 13 years and followed over a period of 12–30 months. Conclusions: SDF is a practical, accessible and effective non-invasive way to prevent and arrest caries in temporary and permanent teeth. Its application requires regular monitoring. The resulting black spot is diminished by immediate application of potassium iodide but this may affect its effectiveness.
