Silver Diamine Fluoride Chemical Mechanisms of Action as a Caries Arresting and Preventing Agent

摘要

The chemical mechanisms of silver diamine ? uoride, a cariesarresting and caries-preventing agent, are presented using Raman spectroscopy.Findings included that SDF works as a caries-arresting agent by forming Ag3PO4and as a caries-preventing agent by forming ? uorapatite (FAP), that the timeneeded for SDF to work as a caries-preventive agent is shorter than that neededto work as a caries-arresting agent, and the presence of thiol group (caries)delayed the formation of Ag3PO4 and FAP
