Pit and fissure sealants are used in dental offices to prevent cavities. These sealants are applied to the top surfaces of teeth to seal them off from plaque. The tooth is cleaned and a mild acid solution is applied to aid in bonding, then the pit and fissure sealant is applied and cured. The most common polymerization or curing procedure is light, however, chemical curing is also used. Pit and fissure sealants can be pure resin, composites or compomers and can be clear, opaque or tinted.
UltraSeal XT plus hydrophobic pit and fissure sealant is a light-cured, radiopaque, fluoride-releasing composite sealant. It is strong and wear resistant because it is a 58%-filled resin and has low polymerization shrinkage. The spiral in the Inspiral™ Brush tip causes shear thinning of the filled, thixotropic resin, reducing its viscosity as it is placed. The resin firms when shear thinning ceases and placement is complete, preventing the resin from running before it can be light cured. Using PrimaDry™ drying agent with UltraSeal XT plus sealant enhances penetration into pits and fissures1 by eliminating moisture that can cause failure in hydrophobic sealants.
- High retention rate
- Direct delivery into difficult-to-access areas
- Bubble-free, drip-free placement
- High marginal retention prevents microleakage
- Penetrates deepest pits and fissures
