This document summarizes different fluoride preparations and their uses for dental professionals. It discusses acidulated phosphate fluoride solutions and gels, which contain fluoride to promote remineralization and reduce cavities. Neutral sodium fluoride gels are recommended instead of acidulated phosphate fluoride for patients with existing restorations. Fluoride varnishes are highly concentrated forms of fluoride that adhere to tooth surfaces for hours. Fissure sealants are restorative materials used to seal pits and fissures in teeth and aid in cleaning, as brush filaments cannot reach those areas. The document provides details on preparation, application, and precautions for different fluoride therapies.
