Histological and Morphological Evaluation of Exfoliated Silver Diamine Fluoride-Treated Carious Primary Teeth

Silver diamine fluoride (SDF) is a minimally invasive treatment modality that has gained attention in recent years owing to its remineralizing capability. However, there is limited research on its effect at a microscopic level. This case series presents three cases of exfoliated primary teeth where histologic and morphological analysis was performed after a single application of SDF on carious dentin. This paper provides valuable insights into the long-term and sustained effectiveness of SDF, making it a cost-effective treatment for young, uncooperative children including those with special health care needs. In addition, it also highlights that periodic re-application of SDF can enhance the overall caries-arresting potential. However, despite the clinical success, the inclusion of silver particles deep within the dentinal tubules results in pronounced discoloration, which is a significant drawback of SDF. Future research has to be directed toward innovative techniques to overcome discoloration while maintaining its efficacy.
