Which organization provides guidelines for SDF re-evaluation timing?

• A. AADP
• B. ADA
• C. AAPD
• D. WHO

Answer: (A)

The thing being tested is which organization sets guidance on when to re-evaluate after using silver diamine fluoride (SDF). After SDF is applied, patients are followed to check whether the caries is arrested and to decide if reapplication or additional care is needed. This follow-up timing is most clearly defined by pediatric-focused dental guidelines, since children are the primary population using SDF for caries management.

Among the major bodies, the American Academy of Pediatric Dentistry provides guidelines tailored to children, including recommended intervals for re-evaluation after SDF treatment. They offer practical pediatric follow-up timelines (often 6–12 months, adjusted for caries activity and risk) and emphasize regular reassessment to monitor arrest and determine if reapplication is warranted. While the ADA covers general dental practice guidelines and the WHO offers broad public health guidance, the most specific, child-centered recommendations on SDF re-evaluation timing come from the AAPD.
