Which term describes fluoride that is ingested and circulated throughout the body (reworded)?

• A. Systemic Fluoride
• B. Topical Fluoride
• C. Fluoride Varnish
• D. Sealant

Answer: (A)

Systemic fluoride is the fluoride that is ingested and circulated through the bloodstream to reach body tissues, including developing teeth. When you swallow fluoride from water, foods, or supplements, it enters the circulation and becomes available in saliva, helping protect teeth systemically as they form and continue to remineralize over time. Topical fluoride, by contrast, is applied directly to the teeth to provide a local effect on the tooth surface. Fluoride varnish is a concentrated topical treatment, and a sealant is a resin applied to the chewing surfaces to prevent decay, not a circulating form of fluoride.
