Silver Diammine Fluoride

Silver diammine fluoride (pronunciation: /ˈsɪlvər daɪˈæmiːn ˈflʊəraɪd/), also known as SDF or Ag(NH3)2F, is a topical medicament used in dentistry to prevent and halt tooth decay and relieve dentinal hypersensitivity.

Etymology

The term "silver diammine fluoride" is derived from its chemical composition. "Silver" refers to the silver (Ag) element in the compound, "diammine" refers to the two ammonia (NH3) molecules, and "fluoride" refers to the fluoride (F) ion.

Usage

Silver diammine fluoride is primarily used in the field of dentistry. It is a colorless liquid that is applied topically to the teeth. It has been found to be effective in preventing and arresting caries (tooth decay) and relieving dentinal hypersensitivity.

Mechanism of Action

The silver ion in the compound acts as an antimicrobial agent, killing bacteria and inhibiting the formation of new colonies. The fluoride ion promotes the remineralization of the tooth structure, making it more resistant to decay. The ammonia serves as a stabilizing agent.
