Impact of Silver Diamine Fluoride Pretreatment on the Bonding Performance of Glass Ionomer Cement to Human Dentin: An In Vitro Evaluation

Silver diamine fluoride (SDF) has demonstrated particular effectiveness in inhibiting dentinal caries in primary teeth.The IntroductIonDental caries results in the destruction of both enamel and dentin, leading to compromised tooth form and function.The concept of using artificial biomaterials to replace damaged or lost dental tissues is well established, particularly when performed at an early stage to restore the biological integrity, functional efficiency, and esthetic appearance of the tooth.Restorative dentistry has therefore become increasingly significant, as it relies on adhesive materials that bond to tooth surfaces, allowing for conservative cavity preparation while minimizing microleakage.This approach reduces discoloration, postoperative sensitivity, and the risk of recurrent caries. 1,2or many decades, metallic restorative materials have been routinely used in restorative dentistry because of their durability and clinical reliability.However, their use has gradually declined owing to concerns related to esthetics and the presence of mercury, along with increasing patient preference for tooth-colored restorations.These limitations have driven the development and adoption of alternative materials that offer improved esthetic outcomes along with adhesive capabilities. 3n response to the limitations of amalgam, glass ionomer cement (GIC) has gained popularity as an alternative material for tooth restoration.It is valued for its ability to chemically interact with tooth structure and its sustained fluoride release, which contributes to remineralization.Owing to these properties, along with its promising biological compatibility, conventional GIC has become a commonly used material in restorative dental practice.
