Aegis® Pit and Fissure Sealant contains the “smart material” Amorphous Calcium Phosphate (ACP). The ACP filler is resilient and flexible, creating a stronger and longer-lasting sealant. Aegis Pit and Fissure Sealant has low shrinkage, good margin, and a slow rate of stress development, so as not to chip off. Aegis Pit and Fissure Sealant can be used with any light-curing device and offers the added convenience of dispensing through syringe tips. Aegis’ controlled flowability keeps the sealant on the tooth while completely filling the pits and fissures. When properly maintained and placed, Aegis forms a chemical and thermal barrier that can help keep patients free from carious lesions on the occlusal surfaces. The new resin formula allows for better flow and handling. Sealant cures to an opaque film on enamel.
