What is the purpose of fluoride varnish or gel in pediatric dentistry?

• A. For systemic fluoride supplementation.
• B. For enamel remineralization and caries prevention by delivering fluoride topically.
• C. To adjust occlusion.
• D. For whitening.

Answer: (B)

Fluoride varnish and gel are used as a topical fluoride therapy to protect developing teeth by delivering a high concentration of fluoride directly to the enamel. The fluoride promotes remineralization of early caries lesions and makes enamel more resistant to acid attack, helping prevent decay. This topical approach is especially useful in children because it targets the teeth where decay begins and can be applied quickly in a single visit with minimal risk of swallowing. It is not intended for systemic fluoride supplementation, does not adjust occlusion, and is not a whitening treatment.
