UltraSeal XT hydro is a light-cured, radiopaque, fluoride-releasing composite sealant. It is stronger and more wear resistant because it is a 53%-filled resin and has less polymerization shrinkage than competitive products. The spiral brush action of the Inspiral® Brush tip causes shear thinning of the filled, thixotropic UltraSeal XT hydro, reducing its viscosity as it is placed. The resin firms when shear thinning ceases and placement is complete, preventing it from running before it can be light cured. The hydrophilic chemistry with its characteristic thixotropic nature chases moisture (that in hydrophobic sealants can cause sealant failure) deep into the pits and fissures on a microscopic level. Once there, the advanced adhesive technology securely bonds the sealant to the enamel, increasing marginal retention and reducing microleakage.


Use UltraSeal XT hydro for prophylactic sealing of pits and fissures.

I’ve used UltraSeal XT plus for years. Why would I want to switch to UltraSeal XT hydro?

  • There’s no doubt that UltraSeal XT® plus is a great sealant. If you’re happy using UltraSeal XT plus, then keep using it! However, if you’re interested in trying UltraSeal XT hydro, you may enjoy the fact that you don’t have to apply a drying agent before placing the sealant. This saves valuable time, and it’s ideal in situations where moisture control is challenging. Also, UltraSeal XT hydro’s fluorescing properties make checking its retention easy.

Will UltraSeal XT hydro replace UltraSeal XT plus?

  • No. UltraSeal XT plus is the industry leader and has a long history of clinical success. We do not have plans to discontinue it.

Is UltraSeal XT hydro just a combination of UltraSeal XT plus and a drying agent?

  • No, it isn’t that simple. Eight years in the making, UltraSeal XT hydro is the result of combining advanced adhesive monomers with other proprietary chemistries. The adhesive monomers are what cause UltraSeal XT hydro to become a hydrophilic sealant.

Does UltraSeal XT hydro contain any of the eight common food allergens (milk, eggs, peanuts, tree nuts, fish, shellfish, soy, wheat/gluten)?

  • No.

Do I need a bonding agent with UltraSeal XT hydro?

  • No. You just need to etch, apply UltraSeal XT hydro, then light cure. Please refer to instructions for use for complete procedure.

How many teeth can I seal with one 1.2ml UltraSeal XT hydro syringe?

  • Approximately 35–40 teeth.

Can UltraSeal XT hydro be used for a microrestorative or as an “initial layer” of a composite restoration?

  • No. UltraSeal XT hydro is indicated only for prophylactic sealing of pits and fissures.

How much moisture should be on the tooth?

  • Similar to Ultradent’s hydrophilic bonding agents (Peak® Universal Bond and PQ1™), the tooth should be slightly moist but not puddled. Do not desiccate the tooth.

How can a hygienist adjust UltraSeal XT hydro without using a bur?

  • Hygienists can use the Inspiral Brush tip to remove excess resin, wiping it off on a 2×2 and removing again until there is only a minimal amount in the fissure. Alternatively, they can flood DeOx® over the sealant and have the patient close. They would then cure from the labial for 20 seconds, have the patient open their mouth, then cure directly on the sealant. If they see any ridge from an opposing cusp sinking into the uncured resin, they should be able to remove it with a sharp scaler.

Can PrimaDry be used with UltraSeal XT hydro?

  • No, we do not recommend the use of PrimaDry® with UltraSeal XT hydro. UltraSeal XT hydro works best on slightly moist teeth, and PrimaDry is designed to help desiccate the tooth.
