In a high caries-risk child, which preventive strategies should accompany cavity management?

• A. Fluoride varnish, sealants, dietary counseling, and oral hygiene instruction
• B. Fluoride varnish and silver diamine fluoride only
• C. Sealants and dietary counseling only
• D. Fluoride varnish, sealants, dietary counseling, oral hygiene instruction, and consideration of silver diamine fluoride to arrest lesions

Answer: (D)

Managing cavities in a high caries‑risk child isn’t about a single tactic; it’s about a comprehensive plan that addresses all factors driving decay. Fluoride varnish boosts remineralization and helps prevent new lesions, while sealants protect vulnerable chewing surfaces from decay. Dietary counseling tackles the sugar and frequency of acid attacks that feed caries, and oral hygiene instruction reduces plaque and bacterial load. Adding silver diamine fluoride offers a non‑invasive way to arrest active decay, which is especially helpful when cooperation, access to care, or immediate restorative options are limited. Because this approach combines remineralization, barrier protection, behavior modification, and lesion arrest as needed, it provides the most effective, holistic management for a high‑risk child.
