What is the purpose of using sealant material with fluoride added?

The rationale behind using sealant material that includes fluoride is primarily related to caries prevention. Fluoride is known to enhance enamel remineralization and inhibit the progression of caries. When fluoride is incorporated into sealant materials, it not only provides a protective barrier over the tooth surface but also helps in inhibiting caries growth in the enamel that surrounds the sealant. This is particularly important because areas prone to cavities, like pits and fissures, can benefit from the added fluoride, potentially reducing the risk of decay in those susceptible areas.

In contrast, although improving aesthetic appearance, reducing viscosity, and prolonging shelf life are important aspects of dental materials, they do not directly relate to the specific preventive benefits that fluoride offers when added to sealants. Aesthetic improvements focus more on the visual aspects; viscosity relates to the application properties of the sealant; and shelf life pertains to product storage and usability rather than its active preventive effects in dental health.
