FAQ
New Predicta Desensitizer is changing the way clinicians treat dentin hypersensitivity by using the elements that are naturally found in the tooth, (calcium and phosphate) and restoring them to the tooth in the form of hydroxyapatite plugs that quickly block the open tubules. As calcium and
phosphate ions continue to release, mineralization occurs to further seal the tubules. Also, there are no methacrylate’s or soft-tissue irritating chemicals used in production.
Yes. The desensitizing gel must be able to come in contact with the open tubules in order to penetrate and plug them.
Absolutely. It is moisture tolerant, therefore, air drying the tooth with an air syringe is not necessary. Simply blot the treatment site with a cotton roll or cotton pledget, apply the gel and leave it on the tooth for 30-40 seconds.
No. Unlike many resin desensitizers, Predicta Bioactive Desensitizer does not require the use of a curing light.
Bioactivity! Bioactive materials release calcium, phosphate and fluoride, which trigger the formation of a protective layer of mineral apatite, the predominant element found in both enamel and dentin. They are also dual cure, eliminating the worry in incomplete cure of materials leading to sensitivity and failure of restoration.
Predicta Bulk is a highly polishable universal composite, that can be used in all areas of the mouth, and is indicated for Class I through V restorations. Predicta Core is indicated for core build-ups and as a post cement. The addition of Zirconia helps provide a strong and stable support for crowns made of zirconia, lithium disilicate, porcelain, PFM and metal.
Materials must always be brought to room temperature prior to use.
The most likely reason a dual-cure composite doesn’t set is failure to double bleed.
Remove the shipping cap. Extrude a small amount of material onto pad until it flows freely from both orifices. Place mixing tip on cartridge and extrude a pea sized amount onto pad prior to placing in mouth.
Regular viscosity is used ideally for large restorations where stability is desirable and material drift is not. Low viscosity is recommended for smaller preps where the ability to flow and adapt into tighter spaces is preferred and for better adaptation of hard to access prep margins and line angles. Both HV and LV versions can be used in all restorative situations. These guidelines are an aid when choosing a bulk-fill that more closely matches your needs.
No, Predicta Bioactive Bulk is a nanohybrid, it is optimized for wear resistance and is highly polishable.
Like all dual-cure composites there will be some self-etching bonding agents that are not compatible with Predicta Bulk. If you are unsure Parkell recommends you call the manufacturer. However, you can use any Parkell bonding agent with any Parkell product.
Viscosity selection is a personal preference. Both LV and HV are appropriate for and can be used in all core build-up and post cementation situations. However, as a general rule, the high viscosity is more stackable and is ideally suited for larger core build-ups. The low viscosity is more flowable and recommended for cases where post cementation and core are done together.
Like all dual-cure composites there will be some self-etching bonding agents that are not compatible with Predicta Core. If you are unsure Parkell recommends you call the manufacturer of the bonding agent and ask if it is compatible with dual cure composites. However, all Parkell bonding agents work with light cure, dual cure and self-cure composites as of now.
This device is contraindicated for use on a patient, OR BY AN OPERATOR, wearing any intracorporeal devices, such as cardiac pacemakers, defibrillators, insulin pumps, etc.
The Digitest 3 cannot be used in the presence of flammable or explosive gases. The use of dental nitrous oxide/oxygen analgesia is not advisable because you would not get an accurate response. To accurately diagnose the condition of the tooth, pulp testing must be performed on a patient who has not received local anesthesia or gas analgesia.
The use of accessories other than those specified, or provided by Parkell Europe will result in improper operation. Do not use.
The battery is low and needs to be replaced. Replace it as explained in the section “Installing/Replacing” the Battery. Battery should be removed if unit is to be stored unused for more than 30 days.
It may be tightened by carefully inserting a flat screwdriver blade into the split metal base of the probe and gently expanding the sides apart with a twist of the tool.
No. Discard and replace any tooth probe if the metal or the insulation becomes damaged during use.
The Parkell Digitest 3 is to be used in conjunction with other diagnostic tests such as x rays, temperature tests, percussion etc. in order to confirm tooth vitality.
No. Studies indicate cold testing prior to electric pulp testing does not impact the results of the electric pulp test.
The tooth probes, ground clip and wire assembly may be sterilized in any conventional steam autoclave. Comply with manufacturers recommended procedures.
NO. Autoclaving the Digitest 3 power unit will damage it.
Not necessarily. Each patient will have their own base level to electrical stimulus that must be determined at the time of testing. The base level for each patient can be determined by pulp testing similar teeth to the teeth in question. To confirm the diagnosis, a corresponding control tooth in the same arch should be tested. Molars should be matched to molars, premolars to premolars, cuspids to cuspids, and incisors to incisors. If this is not possible because teeth are
absent, endodontically treated, have full coverage or very large restorations a similar tooth in the opposite arch should be used.
Explain to the patient that they are in control of the test and can stop it at any time. In most instances, the first sensation patients notice is a tingling feeling. When the patient feels a change in the tooth (tingling, pulsing, buzzing or slight discomfort) all they need to do is let go of the metal ground Clip and the test will be over. This should minimize the potential for patient discomfort.
Retrieve DC is a long-term, dual-cure, provisional resin cement for implant retained crowns and bridges.
No
Retrieve DC was specifically formulated to address the unique requirements of cementing prosthodontic restorations to implant abutments. Stronger than temporary cements, yet less retentive than permanent cements, Retrieve DC has the ability to provide long-term cementation of implant restorations, while allowing for the the removal of these restorations when placed on a properly lubricated abutment.
As a rule, you should consider lubricating all preps that you deem candidates for future crown removal.
Water-based lubricants or glycerin are recommended.
It depends on the height and taper of the abutment. As the resistance and retention form of the implant abutment increases the greater the need for increasing the percentage of the abutment surface that must be lubricated. Prior to cementation coat at least 50% of the coronal portion of the implant abutment head with lubricant. In some cases, up to 75% of the abutment surface may
require lubrication for the restoration to be removed successfully. When lubricating an abutment, begin at the occlusal/incisal surface and apply the chosen lubricant down the walls of the abutment to the appropriate level. To create a tight marginal seal, do not lubricate the margins. This should give good retention, while allowing removal of the prosthesis later.
It depends. If the abutment has long parallel walls, a crown cemented without previously lubricating the preparation will probably be very difficult, if not impossible to remove without damage to the crown, the implant abutment, or both. Crowns cemented on shorter abutments may be removable with some effort.
Yes, Retrieve DC is highly radiopaque, (300% of Aluminum). Because of its high radiopacity Retrieve DC helps to reduce the possibility of implant failure due to peri-implantitis. A post implant x-ray can help identify excess flash for easier removal.
Retrieve DC was developed specifically for use with implants. For short-term cementation on natural teeth, we recommend Parkell’s ETC (Easy Temporary Cement).
Retrieve DC is hand dispensed from an automix, dual-barrel syringe through single use, disposable mixing tips. No gun is required.
