Silver Diamine Fluoride: What Is Its Place in Oral Health Care?

Silver compounds have been used for their medical properties for centuries and in dentistry for more than a century. In recent years, the use of a topical fluoride solution, namely silver diamine fluoride (SDF), in dental treatment has been drawing increasing attention. SDF is a solution containing ionic silver, fluoride, and ammonia that arrests the progress of carious lesions and prevents the development of future caries. The fluoride component of SDF contributes to remineralization and fluorapatite formation while the silver provides the antimicrobial activity for the material and inhibits biofilm formation. SDF has been used in some countries, including Japan and China, as a caries-arresting and anti-hypersensitivity agent. In 2014, SDF was approved by the US Food and Drug Administration as a treatment for dentinal sensitivity. Promising results of laboratory studies and clinical trials have suggested that SDF is more effective than other fluoride agents to halt the caries process. This seminar provides an overview of the clinical use of SDF in dental treatment.

Learning objectives:
  • Identify the FDA-approved indications for SDF
  • Describe the mechanism of action of SDF
  • List the contraindications for SDF
  • List the precautions needed during SDF application
