UltraSeal XT™ plus

Hydrophobic Pit and Fissure Sealant

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. When the resin stops flowing the shear thinning ceases and placement is complete,1 preventing the resin from running before it can be light cured. UltraSeal XT plus penetrates the deepest pits and fissures.1 Using PrimaDry drying agent with UltraSeal XT plus sealant enhances penetration into pits and fissures by eliminating moisture that can cause failure in hydrophobic sealants.

  • Penetrates deepest pits and fissures1
  • Thixotropic/ideal viscosity flowability1
  • Direct delivery into difficult-to-access areas
  • Resin-based sealants have high retention rates2
  • Bubble-free, drip-free placement
  • Better at preventing microleakage than other sealants3
  • Four shades: Opaque White, Clear, A1, A2
  • Use with Inspiral™ Brush tip
  • Certified gluten free

Revolutionary Delivery

The easiest and most efficient way to ensure UltraSeal XT plus sealant is delivered deep into pits and fissures is to use the Inspiral Brush tip. The unique helical channel of the tip thins the viscous material, and the fine brush fibers help guide the resin directly where you want it to go.

The Leader for Nearly 15 Years

Since 1998, Reality has favorably reviewed UltraSeal XT plus sealant, calling it “simply the best”3 among its countless competitors!

Optimal Viscosity

UltraSeal XT plus sealant flows easily into the tiniest pits and fissures, but doesn’t run after placement.

Fluoride Releasing

UltraSeal XT plus sealant releases fluoride to the tooth to promote healthy enamel.

​"A pediatric dentist can't get any more minimally invasive than preventing the problem to begin with...and I have never found a sealant material with an outcome that even rivals UltraSeal XT plus. It's simply the best."

Dr. Thomas M. Musson – North Wilkesboro, NC

​"Being a pediatric dentist, this is one material I cannot practice without. I have never found such a user-friendly sealant that is so easy to apply and with such excellent retention as UltraSeal XT plus."

Dr. David Goldstein – Orlando, FL

​"I love the UltraSeal XT plus sealant. I have used many different sealant products in my office as well as in the dental school in which I am faculty. Actually, all the pediatric dental instructors had tried eight different sealants to compare, and UltraSeal XT plus was unanimously the sealant of choice. The viscosity, multiple shades, partially filled consistency, and the fact it is fluoride releasing make UltraSeal XT plus the most reliable and superior sealant that I choose to use on my patients."

Dr. Angela M. Stout – Erdenheim, PA

​"As a pediatric dentist for 38 years, prevention of cavities is the cornerstone of our practice. We have tried all the sealant products, and UltraSeal XT plus has been the absolute best for ease of application and long-term retention and durability. The best testimony is having moms who were our patients bring their kids to use the sealants. Many of the moms still have sealants in place and have no cavities."

Dr. James Heffner – Davidsonville, MD

Frequently Asked Questions

  • Is UltraSeal XT plus sealant different from other tooth sealants?

    Yes! UltraSeal XT plus sealant has been the leader in sealants since 1998. UltraSeal XT plus sealant is a resin-based sealant, and retention rates of conventional resin-based sealants are much higher than retention rates of glass ionomer sealants.2 UltraSeal XT plus sealant is now and has always been BPA FREE.
  • Is UltraSeal XT plus sealant BPA free?

    Yes. Ultradent has always been concerned with the potential harmful effects of BPA, and as such has never used Bisphenol A in the production of UltraSeal XT plus or UltraSeal XT hydro sealants.

    Read Dr. Fischer's letter on BPA.

  • Can UltraSeal XT plus Opaque White sealant be used as an opaquer?

    We don’t recommend UltraSeal XT plus sealant be used as an opaquer. Instead, we recommend using PermaFlo Dentin Opaquer flowable composite.
  • What is UltraSeal XT plus sealant’s diameter of filler in micrometers, weight percentage, and density?

    The average particle size is 1.5 microns, the sealant is 58% filled by weight, and is 1.73g/ml.
  • Can UltraSeal XT plus sealant be used to splint two teeth together?

    When performing periodontal splinting, it is wise to consider a reinforced restoration such as Ribbond or GlasSpan in conjunction with the restorative material. When either of these products is used, UltraSeal XT plus sealant can be used as the restorative material. Flow characteristics may be addressed with a more viscous material such as PermaFlo flowable composite, which is a 68%-filled resin.
  • Is it true that Sealants for Smiles uses UltraSeal XT plus sealant?

    Yes. Sealants for Smiles is a nonprofit organization that provides oral health education and tooth sealants to children in lower-income schools. Nonprofit organizations are subject to more stringent standards on the type and quality of materials used in their programs. One of the reasons Sealants for Smiles opted to use UltraSeal XT plus sealant was because of its long-standing reputation in the dental field.
