Which tool is specifically used to apply the SDF solution to a carious lesion?

• A. Microbrush
• B. Cotton swab
• C. Paintbrush
• D. Spooly applicator

Answer: (A)

Precise placement of silver diamine fluoride on a carious lesion requires a small, controllable applicator that can touch only the affected area. A microbrush has a tiny brush head and a slim handle, allowing you to apply a precise drop of SDF directly to the lesion without contacting surrounding healthy surfaces. This targeted delivery helps concentrate the treatment where it’s needed and minimizes spreading or staining of adjacent tissue. Cotton swabs, paintbrushes, and spooly applicators are less suitable for this purpose because they are bulkier or less controllable, making it harder to apply the solution precisely to small pits or demineralized spots. Thus, the microbrush is the tool specifically used to apply the SDF solution to a carious lesion.
