Peak Self-Etch Adhesive System

What is the shelf life of Peak SE and Peak Resin?
Peak LC Bond Resin – 18 months
Peak SE Primer – 18 months prior to activation (over 30 days after activation)
The MSDS sheets state that the Peak SE Primer needs to be refrigerated and the Peak LC Bond is room temperature. This is for storage – not all the time. This means that if the product is not used daily it should be refrigerated. The Peak LC Bond can be refrigerated but needs to be brought up to room temp before use.

How many applications per syringe of each component?
Peak LC Bond Resin – 40+ restorations? (not exact – many variables)
Peak SE Primer – 30+ restorations (not exact – many variables)

How important is the moistness of the area where the Peak is being applied?
Not a huge factor – no visible moisture (puddles) but DO NOT desiccate

What is the solvent used in Peak SE?
Ethyl alcohol

What color is the Peak LC Bond Resin?
Light yellow, then clear after curing

Can fragments from the burst membrane be a problem?
No. The membrane is inert and designed to split, not fragment. Should a fragment break loose for any reason, it will not have any effect on the Peak SE Primer.

Will the Peak adhere to the Matrix band?
Omni Matrix – no

Should Consepsis be used prior to SE?
Yes, for antimicrobial effect to reduced chance of post op sensitivity caused by residual bacteria. If fact, with any non- phosphoric bonding system, Consepsis should be used.

Can Peak SE be used for porcelain repair / metal bonding?
Yes.

Is there fluoride in the Peak LC Bond resin?
No.

Technical Q&A

How should bonding to sclerotic dentin be addressed?  Will etching twice be effective?
Dr. Ron Jackson supports this idea when bonding to dark, shiny highly mineralized dentin. Etch once for 15 seconds, then rinse and dry; etch again, but leave moist. It is commonly understood that etching sclerotic dentin quickly neutralizes the etch due to high mineral content. A second etch will help get better penetration.

Which Ultradent products contain camphorquinone?
All of our light-cured products contain CQ. Many of our products also contain proprietary photo initiators, but they will all cure completely with any light that will cure camphorquinone.

How long does CONSEPSIS have to be in place to be considered antibacterial?
2% chlorhexidine placed in contact with a surface for 5-10 minutes disinfects the surface. If it is not rinsed off, it provides bactericidal activity for up to two days. This is a CDC recommended protocol for ICU venous sites. In a tooth, it will not be rinsed off, so this activity will continue as stated.

Back to top

How do I apply CONSEPSIS to kill streptococcus mutans?
Chlorhexidine does a wonderful job on streptococcus mutans. We recommend applying Consepsis for one minute and then air drying. We do not teach to rinse off the Consepsis. This leaves the chlorhexidine to kill bacteria as long as it is active.

What is the abrasive pumice in CONSEPSIS SCRUB?
Consepsis Scrub contains a silicate abrasive.

Is PERMAQUICK Bis-GMA?  How does it react with Bis-GMA composite?
PermaQuik contains Bis-GMA resin. PermaQuik and Bis-GMA composites are both methacrylate-based resins that will bond with one another.

Back to top

How does PERMAQUICK create elastic bonds?
The PermaQuick Bonding System has this elastic characteristic due to its natural organic resin content. These natural, organic, elastic resins tend to compensate for polymerization shrinkage.

Back to top

Will PERMAQUICK soften zinc oxide eugenol?
Yes. The ethanol in PermaQuick primers may alter the physical properties of the eugenol in ZOE. Because of this, we recommend placing a glass ionomer restorative or Ultra-Blend plus over the ZOE. This would also prevent any adverse effects on bonding due to the reaction between the eugenol and PermaQuick.

Are there figures showing ULTRADENT PORCELAIN ETCH 9.5% hydrofluoric acid being more effective than other, less concentrated hydrofluoric based etching agents?
The etch is in a gel form, therefore the viscosity allows a controlled application, preventing tissue contact. We recommend that Ultradent's EtchArrest be used in conjunction with the Porcelain Etch to protect the surrounding hard and soft tissues and also to be used as a neutralizing agent following the etching procedure. If this is not used then a rubber dam can be placed to isolate the area. We do not have studies comparing a 9.5% hydrofluoric acid to a lower percentage of hydrofluoric acid. In a Reality evaluation, Ultradent's Porcelain Etch received the top rating. In fact, 75% of the competitors' products included in the comparison were 9.5% hydrofluoric acid. A lower percentage of hydrofluoric acid would require a longer etch time to obtain an optimum porcelain surface for bonding. Therefore, it would not be time efficient. One minute is necessary for Ultradent's Porcelain Etch according to studies conducted at the University of Connecticut by C.H. Pameijer D.M.D., Ph.D.

What is meant by the phrase “100% cohesive failure” found in the PORCELAIN ETCH instructions?
It means the fractures occurred in the porcelain, not at the adhesive interface.

Back to top

Can you explain how a highly-filled bonding resin creates a higher bond strength?
Fillers in bonding agents facilitate stronger bonds because their presence reduces polymerization shrinkage, has a lower coefficient of expansion, and reduction in water absorption of the bonding resin. Additionally, the cured resin itself is stronger.

Does PQ1 contain dyes?
No.

Back to top

What kind of filler is found in PQ1?
The filler is silica dioxide.

Back to top

What is the film thickness of PQ1?
The film thickness is 15-20 microns on average.

Back to top

Can Gluma desensitizing agent be used before PQ1 under a composite?
Yes, but since PQ1 contains HEMA, which is the desensitizer in Gluma, it is not necessary to use both products.

Back to top

What type of monomer does PQ1 contain?
PQ1 is BisGMA based but also contains other methacrylate-based hydrophilic monomers.

Back to top

How can excess PQ1 be thinned in the corners of a deep Class II and from against the matrix band? Sometimes, the wall up against the matrix band is all PQ1.
Air blasts can be used to thin the material. An alternative to air thinning is to vacuum thin with Ultradent's Luer Vacuum Adapter and an 18-22 gauge Endo Eze cannula. This prevents over thinning and splatter of resin onto soft tissues. Follow with 5-10 seconds of gentle air drying to evaporate solvent.

Back to top

Should PQ1 be scrubbed into the tooth structure?
We have found that firm scrubbing helps bond strengths when working on dentin. We have found that scrubbing can slightly reduce bond strengths to enamel.

What is the main chemical component of ULTRADENT SILANE?
Methacryloxy propyl trimethoxy silane.

Back to top

How does SILANE function?
Silane is a coupling agent that enables resins to bond to silicas and silicates.

Back to top

If SILANE has been opened, will it be as effective/fresh the next time it is used?
Ultradent's Silane is designed to be effective within its three-year shelf life. Its syringe delivery keeps the material fresh within the syringe and the Teknaflo prevents air from being aspirated back into the syringe.

Does the tooth absorb ULTRA-BLEND PLUS over a period of time?
UltraBlend is a light cured resin that contains calcium hydroxide. The beauty and market advantage of delivery of calcium hydroxide via a light cured resin is that it will not weaken or “wash out.”

Back to top

Does ULTRA-BLEND PLUS become porous over time?
Ultra-Blend plus has a urethane dimethacrylate base (resin) so it is not soluble and therefore should not become porous.

Back to top

Before placing amalgam over a liner made of ULTRA-BLEND PLUS, is it necessary to remove Ultra-Blend's oxygen inhibition layer?
No.

Back to top

If ZOE contains eugenol and eugenol inhibits the polymerization of resin, can I put ULTRA-BLEND PLUS, which is a resin, over the top of the eugenol?
Yes, this will be just fine. Ultra-Blend plus cures reasonably well against ZOE.

Back to top

Does ULTRA-ETCH contain blue dyes?
Ultra-Etch contains two inorganic pigments. It does not contain a dye.
