Delton - the most trusted name in Pit & Fissure Sealants now offers a product which eliminates the guess work involved with placing sealants and confirming placement during recall appointments. Delton? Seal-N-Glo Illuminating Pit & Fissure Sealant is a 38% filled, syringe delivered, opaque sealant with fluoride. Through the use of a UV pen light, Seal-N-Glo fluoresces a blue/white color. The fluorescent glow provides clinicians with a visual verification of the sealant margins at the time of placement and offers the easiest way to verify retention and inspect margins during patient recall appointments. Unlike other products on the market, Seal-N-Glo's fluorescent technology is valuable throughout the lifetime of the sealant.
