Alpha-Seal® is a light cure, resin-based Pit & Fissure Sealant with fluoride. This sealant contains 50% radiopaque nano-sized fillers. The hard setting, wear-resistant material has an ideal flowable viscosity for maximum coverage and protection to seal the pits and fi fissures of teeth susceptible to caries. The syringe needle tips allow for quick and accurate placement of the material. Alpha-Seal® is available in an Opaque shade to allow for easy identification during patient examinations and in a Clear shade for patients who wish to have an “invisible” sealant.
