Correct answer: D — Arrest of active carious lesions in primary teeth
Silver diamine fluoride (SDF) 38% is an evidence-based, non-invasive topical agent that arrests active carious lesions. The silver component provides antimicrobial action (kills cariogenic bacteria), the fluoride promotes remineralisation, and the ammonia stabilises the solution at high pH. SDF is particularly useful in young children, patients with special healthcare needs, and situations where conventional treatment is not feasible. The main disadvantage is permanent black staining of treated carious dentin (silver precipitation), which limits aesthetic acceptability.
