Temporal Exposure of Dermal Fibroblasts to Silver Diamine Fluoride and Fluorine NMR Quantitation.

Objective: Silver diamine fluoride has been advocated as a caries arresting material for Early Childhood Caries (ECC) and has received considerable public attention as the "silver bullet". However, cytotoxicity tests on the current concentrations of Silver Diamine Fluoride (SDF) to soft tissue have not been thoroughly assessed and analyzed at selected time intervals. The level of fluoride that is present within human cells has yet to be quantified.
