Li Y, et al. - Investigators assessed the data to research over the consequences of 38% silver diamine fluoride (SDF) on carious lesions of human deciduous teeth using quantitative backscattered electron scanning electron microscopy (qBSE-SEM), energy-dispersive X-ray spectroscopy (EDX), and micro-computed tomography (micro-CT). They observed the penetration of silver particles through the pellicle complex along with the rod sheaths into the demineralized enamel rods and the dentinal tubules. These particles formed silver-enriched barriers surrounding the carious lesions at depths up to 2,490.2 μm (mean 744.7 ± 448.7 μm) within the dentinal tubules of the carious lesions. Silver precipitation was noticed in the pulp chamber when analyzed with micro-CT.
