Testimonials

​"I have used Prime and Bond,* Single Bond,* Solo Bond,* and a few others. The consistency of results has been better with PQ1 than with any of the others, and 90% of the time, there is less sensitivity."

Dr. Robert Anderson – Clearfield, UT

​"Before using PQ1, I did not trust my adhesive. Mechanical retention was still my only security. Since switching to PQ1, I don't need undercuts in my preps and I no longer use any pins."

Dr. Michael Stephens – San Antonio, TX

Frequently Asked Questions

  • Can I use PQ1 bonding resin with all curing lights?

    PQ1 bonding resin cures with all lights, however, we do not recommend use with argon lasers.

  • What kind of filler is found in PQ1 bonding resin?

    The fillers are silica dioxide and FluorUtite.

  • What is the film thickness of PQ1 bonding resin?

    PQ1 bonding resin can be thinned to 2 µm2
  • What type of monomer does PQ1 bonding resin contain?

    PQ1 bonding resin is BisGMA based but also contains other methacrylate-based hydrophilic monomers.

  • Are there any instances where the etch step may be skipped with PQ1 bondig resin?

    The only instances where the etch step can be skipped is on deciduous teeth, deep subgingival class V, or deep subgingival class II preparations. In these cases, etching may initiate bleeding. Acid etch is not just important for roughening the bonding surface; it is also important for cleaning this surface. If the doctor skips the etch step, they should apply some Consepsis prior to placing the restoration. For the best bonds, however, the doctors should still etch.
