Alpha-Seal® is a light-curing, fluoride-releasing, resin-based fissure and pit sealant. This sealant contains 50% nano-sized radiopaque fillers. The tough, wear-resistant material has an ideal fluid viscosity for maximum coverage and protection to seal pits and fissures in teeth susceptible to decay. Fluoride helps in preventing cavities and inhibiting enamel demineralization. Syringe needle tips allow for fast and accurate material placement. Alpha-Seal® is available in an opaque shade to allow easy identification during patient exams and in a light shade for patients who wish to have an "invisible" sealant.
