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, colour adaptability and dual cure properties are the key features. Predicta Bioactive Bulk contains nano-hydroxiapatite, releases calcium and phosphate ions and releases and recharges fluoride. Bioactivity is known in the field to equate to stronger bonds between the restoration and tooth, penetration and filling of micro-gaps, reduction in sensitivity, guard against secondary caries, and the sealing of margins against microleakage. Predicta Bioactive Bulk is available in two translucent shades matching most natural tooth shades. It is a dual-cure resin composite that can be used to fill any size cavity preparation, all the way up to the occlusal surface, without any need for additional layering.
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.
Insert the cartridge into the dispensing gun or plunger, remove the shipping cap, then bleed material from both orifices onto a pad until it flows freely. Affix the mixing tip, express a pea-sized amount through it, then proceed immediately to placement.
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, however all good quality universal bonding agents are compatible with Predicta Bioactive Bulk.
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.
No. The Digitest 3 should not be used on a patient or by an operator who has implanted medical devices, such as pacemakers, defibrillators, or insulin pumps. It may interfere with these devices and cause harm.
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. This adjustment method is outlined in the official Digitest 3 IFU.
No. Discard and replace any tooth probe if the metal or the insulation becomes damaged during use. You can purchase a new probe from our official accessories here.
Parkell’s 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.

Yes, the probes, the wire and the metal clip can be cleaned and disinfected in a washer disinfector.
The procedure below has been validated according to EN ISO 15883:
- Use enzymatic or low alkaline, suited for medical devices, non-corrosive, neutral cleaning agent with minimal foaming characteristics, suited for medical devices.
- Use drinking water quality for cleaning and deionized or purified water for final rinse/disinfection.
- Load the instruments in an open position in the washer-disinfector. Use a suitable instrument tray.
- Pre-wash in cold water, 2 x 2 min
- Main wash with detergent at minimum 55°C, 10 min
- Rinse in warm water, 2x 1 min.
- Final rinse/disinfection in distilled or de-mineralized water at 90°C, minimum 1 min.
- Drying at 110° C, minimum 15 min.
The Digitest 3 power unit should not be reprocessed in a washer disinfector. Since, this will cause damage to it. Also, the Digitest 3 incorporates sophisticated electronic circuitry, it should not be directly sprayed with or soaked in disinfectant.
If a Tooth Probe becomes loose in the mount of the Power Unit, 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. Discard and replace any Tooth Probe if the metal or the insulation becomes damaged during use. This adjustment method is outlined in the official Digitest 3 IFU.
If the Digitest 3 does not deliver any power, it could be due to one of the following reasons:
- Starting the device – To turn on the unit, press the power button to select the desired speed. Then press and hold the power button during the whole test. Releasing the power button will interrupt the power discharge.
- Battery issues – Ensure the battery is fully charged and properly installed. Replace it if depleted.
- Probe or lead connections – Check that probe and lead wire are securely connected. Loose or damaged connections can prevent the unit from functioning.
- Device malfunction – If the batteries and connections are correct but the unit still does not discharge, there may be an internal fault. Contact Parkell technical support service or an authorized service provider for inspection or repair.
Yes, all accessories designed for the Parkell’s Digitest® 3 Pulp Vitality Tester are compatible with earlier versions. This compatibility includes probes, ground clips, and lead wires, which are fully interchangeable across previous and latest versions.
To preserve the Digitest screen from becoming opaque you should avoid wiping with high-alcohol solutions. The device should be disinfected by wiping it with a lint-free towel moistened with an EPA-approved disinfectant containing not more than 30% alcohol, alcohol-free surface disinfectant wipes or disinfecting wipes containing 3-5% hydrogen peroxide.
An opaque or cloudy screen usually indicates residue or screen degradation. Here’s what you can do:
- Chemical residue from cleaning – If a disinfectant or cleaning solution was used, residue may remain on the screen. Wipe gently with a soft, lint-free cloth slightly dampened with distilled water. Do not use high alcohol solutions as they will corrode the display and cause opacity. If the lens becomes hazy or scratched, NOVUS No. 2- Fine Scratch Remover or Polywatch lens polishing cream can be used to remove the damage
- Check batteries and connections – Ensure batteries are charged and probes are properly connected, as poor connections can sometimes affect the display.
No, this is not normal. Under standard use, the batteries in Digitest 3 should last for several weeks to months, depending on the frequency of testing. The replacement battery may be a Duracell ® MN1604, Panasonic ® 6AM6 or equivalent. Although rechargeable 9-Volt batteries may be utilized, they will require more frequent charging because of the considerable voltage required to perform the pulp vitality testing procedure.

C&B-Metabond® is a dental adhesive cement system developed by Parkell, Inc. It’s renowned for its strong and durable bond between metals and bone, making it ideal for various neuroscience applications, including head fixation in rodent models.
Neuroscience researchers apply C&B-Metabond® to securely attach, electrodes, headbars or other fixation devices to the skulls of rodents and other animals. This ensures stable head fixation during in vivo physiological recordings and behavioral experiments.
C&B Metabond is formulated to bond directly to bone, providing a highly secure attachment of implanted devices to the skull without the need for intermediate adhesive layers. Its precisely calibrated measuring accessories ensure consistent, reproducible mixing ratios, in contrast to dental acrylic, which is typically measured by approximation and can therefore yield variable results
Yes, several protocols detail its use. For example, the International Brain Laboratory provides a protocol for headbar implant surgery in mice, highlighting the effectiveness of C&B-Metabond® in their procedures.
For detailed information, including product specifications and purchasing options, visit here.
Parkell’s C&B-Metabond® R&D is a self-cured resin cement providing ultra-high bond strength such as when adhering probes, bars, plate, or the like to bone for research purposes. C&B-Metabond R&D contains 4-META, a high performance adhesive monomer that creates excellent bonds to many surfaces via penetration and the formation of a hybrid layer. Additionally, the system uses a tri-n-butylborane (TBB) catalyst to ensure complete methacrylate polymerization under all conditions.
C&B Metabond eliminates the need for multiple steps, providing a cleaner and more efficient bonding experience. Dental acrylic has no adhesive properties and needs glue to create a bond between the skull and the acrylic. C&B Metabond has adhesive properties when used on its own, and boasts the viscosity required to lock onto devices like headbars or firmly attach electrodes to the brain
C&B-Metabond® comes with a range of accessories, including adjustable applicator brushes, a ceramic mixing dish with a built-in thermometer, and different powder formulations. These accessories ensure precision and ease of use in the lab.

Predicta Bioactive Bulk releases calcium and phosphate ions and releases and recharges fluoride ions to stimulate apatite formation and support the remineralization process at the tooth-material interface.
Predicta Bioactive Bulk is indicated for Class I, II, III, IV, and V restorations, including root surface cavities and post cementation.
Yes, due to its mechanical properties and ease of use Predicta Bioactive Bulk is the ideal amalgam substitute
Yes, Predicta Bioactive Bulk is suitable for the full restoration, it’s designed to fill any size cavity preparation all the way to the occlusal surface without layering and is specifically noted as effective for posterior restorations. It does not require a capping layer of packable composite on top — it’s a nanohybrid formulated for wear resistance and polishability on its own. It is however possible to add a packable composite on top.
No. It’s a nanohybrid optimized for wear resistance and polishability on its own.
Two shades — A1/B1 and A2/B2 — each available in regular viscosity and low viscosity (LV), for four SKUs total: S615 (A1/B1 regular), S616 (A2/B2 regular), S610 (A1/B1 LV), S611 (A2/B2 LV). Each comes as a 5 ml hand-held syringe with 20 mixing tips.
Yes. Predicta Bioactive Bulk Low-Viscosity (LV) version may provide better adaptation when restoring small cavities in primary teeth on pediatric patients. The A1/B1 shade is the best colour match for youg patients.
Light-cure depth is 3–4 mm per light exposure of 20–40 seconds. Beyond that, the material self-cures to full depth at the bottom of the prep over approximately 5 minutes at mouth temperature — so full-depth cure doesn’t rely on light penetration alone. No incremental layering is needed.
A dental curing light emitting blue light at 430–480 nm, with a minimum intensity of 600 mW/cm².
No, warming up before use is not required. However, bring up to room temperature before use
Regular viscosity composite is used ideally for large restorations where stability is desirable and material drift is not. Low viscosity composite 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. HV composite is also a better choice for core building while LV composite is ideal for post cementation. These guidelines are an aid when choosing a bulk-fill that more closely matches your needs.
Users report excellent colour adaptability of Predicta Bulk’s two shades, thanks to the material’s translucency that gives it “chameleon properties”, automatically blending with the surrounding tooth color. The A2/B2 shade matches most adult tooth shades while the A1/B1 shades is ideal for younger patients.
The most common cause with a dual-cure composite is failure to double bleed before use.
Yes, radiopacity is 280% relative to aluminum, improving diagnostic confidence on radiographs and helping distinguish restorations from recurrent decay.
Per the study “Mechanical properties of modern restorative ‘bioactive’ dental materials” (Scientific Reports):
Flexural strength: median 120.40 MPa — the highest among bioactive materials tested.
Modulus of elasticity: 7.27 ± 0.78 GPa
Diametral tensile strength: 47.08 MPa
Vickers hardness (baseline): approximately 47.0–48.8 HV
Per the study “An in vitro micro‐CT assessment of bioactive restorative materials interfacial adaptation to dentin” (Dental Research Journal) comparing three bioactive and a nanohybrid composite, Predicta Bulk followed by Activa Bioactive (Pulpdent) shows the lowest interfacial gap percentages at pulpal, axial. Gingival buccal and lingual walls.
Per the study “The demineralization resistance and mechanical assessments of different bioactive restorative materials for primary and permanent teeth: an in vitro study” (BDJ) comparing two bioactive and a non-bioactive composite, Predicta Bulk and Beautifil Kids (Shofu) demonstrated excellent resistance to demineralization while maintaining mechanical and physical properties comparable to the conventional composite.
Yes. An electric pulp tester can be useful in general practice when a dentist regularly assesses unclear dental pain, trauma, deep restorations or teeth that need follow-up over time. Digitest 3 adds a controlled electrical pulpal test to the diagnostic examination. Its value depends on case mix and should be judged alongside the practice’s existing use of cold testing, radiographs, percussion and other findings.
No. Digitest 3 is intended for licensed dental professionals qualified to use the device, not only endodontists. General and restorative dentists may find it relevant when they manage emergency examinations, dental trauma, deep restorations or uncertain pulpal responses. The device assists pulp assessment; it does not replace clinical training or a complete diagnostic examination.
Electric pulp testing can add a second sensibility response when cold-test findings are uncertain, when symptoms do not clearly identify the responsible tooth, or when a tooth is being monitored after trauma or a deep restoration. Digitest 3 results should be compared with an appropriate control tooth and interpreted with the clinical examination, radiographs, thermal tests and percussion findings.
No. Digitest 3 is intended to complement, not replace, cold testing and other diagnostic methods. Electric pulp testing and cold testing both assess a neural response. Using the findings together, with radiographs, percussion and the wider clinical examination, provides a better basis for interpretation than relying on one response alone.
A control tooth provides an individual reference because there is no single “normal” electric pulp-test reading for every patient or tooth. The IFU recommends comparing the tooth under investigation with a corresponding tooth in the same arch, matching molars with molars, premolars with premolars, canines with canines and incisors with incisors.
Yes. Digitest 3 readings may be used for sequential comparison when the same tooth and an appropriate control tooth are reassessed at later visits. This can be relevant after dental trauma or when a clinician is monitoring a tooth after a deep restoration.
No. Digitest 3 cannot determine treatment by itself. Even a tooth that does not respond at the maximum displayed value may be temporarily non-responsive, particularly after trauma. The IFU recommends follow-up testing and confirmation with another accepted endodontic testing method. Treatment decisions must be based on the complete clinical and radiographic assessment, symptoms and other diagnostic findings.
Sometimes, but only when enough exposed enamel or dentin is available for safe probe contact. The probe must not contact metal, ceramic, composite, gingiva or adjacent conductive surfaces. The included precision probes may help reach a small accessible tooth surface around a restoration, but Digitest 3 does not test through crown material and some teeth may not be suitable for electric testing.
Digitest 3 is designed to apply a gradually increasing stimulus and the test should stop at the patient’s first awareness of tingling, pulsing, buzzing or slight discomfort. The patient should be told what to expect before testing. The IFU describes an optional ground-clip method that can stop the sensation if released, although premature release may compromise the result.
No user calibration procedure is specified in the current EU Instructions for Use. Digitest 3 uses microprocessor-controlled operation and three preset stimulus rates, while routine owner care focuses on battery replacement, cleaning, accessory inspection and authorised service if the unit is damaged or malfunctions.
Digitest 3 can be purchased through several European dental dealers and from Parkell Europe’s product page. The website provides a distributor finder and a form to contact the European sales representative. Availability, tax, delivery terms and local purchasing routes may vary by country.
Dental Adhesives are bonding agents in liquid, low viscosity form. Adding a dual-cure or self-cure resin cement tor dental acrylic is necessary to act as the bridge between the skull and the fixture. C&B Metabond is a cement with adhesive properties and needs no additional layers.
While the majority of researchers do not use the C&B Metabond Dentin Activator, some report that it makes a substantial difference in outcomes. Its necessity largely depends on the duration and nature of the study, as well as the size and activity level of the animal during the experimental period.
The Dentin Activator enhances adhesion by taking advantage of the compositional similarity between teeth and bone, both of which consist primarily of hydroxyapatite. In the same way it primes dentin, it also conditions the bone surface prior to application of C&B Metabond, thereby improving the bonding process.
Notably, researchers who report fixture retention issues are frequently those who have not used the activator. C&B Metabond Dentin Activator is citric acid-based, and existing studies on the effects of citric acid on bone suggest it may provide a meaningful benefit in strengthening the bond between C&B Metabond and the skull.
https://papers.ssrn.com/sol3/papers.cfm?abstract_id=5316423 and https://www.sciencedirect.com/science/article/pii/S0141813026030497
The C&B Dentin Activator is not included in the C&B Metabond C-D Kit but can be purchased as an accessory.
No, these two steps serve distinct purposes and are not interchangeable. Application of the base/catalyst mixture does not chemically prime the skull surface; rather, it wets the surface, thereby facilitating better adaptation of the subsequently applied Metabond cement. In contrast, the Dentin Activator induces actual changes to the bone surface, enhancing its capacity for adhesion.
It should also be noted that wetting the surface with the base/catalyst mixture remains recommended even when the Dentin Activator has already been applied, as this step continues to improve surface wetting independent of the priming effect achieved by the activator.
No, C&B Metabond is not electrically conductive and can be safely used for trials requiring non-conductive cement.
At “gel stage”, excess C&B Metabond can be peeled off wth an instrument without smearing.Cement adhering to metal instruments or the ceramic dish need to be cleaned before it has set. If any remains after setting, C&B-Metabond may be softened by soaking in organic solvents.
Researchers have reported that acetone can be used to dissolve the cement when electrode reuse is required. In cases where more time is available and brain harvesting is not necessary, soaking the electrodes in ethyl acetate (EPA) for approximately one week has also proven effective for recovery. A scalpel or curved scissors may be used to remove the majority of the cement; however, this method requires considerable precision if the integrity of the brain must be preserved
Researchers report adding coloured chalk and food colouring to C&B Metabond to colour code the animals. Coal is also being added if the cement needs to be completely opaque.
Choose the translucent (pink box) powder to prepare a see-through cement.
Choose the radiopaque (green box) powder to prepare an opaque cement. This cement mix has a radiopacity of 27% of aluminium.
C&B Metabond cement sets rapidly when warm. For optimal working time it should always be mixed in its chilled porcelain dish. Working time in a chilled porcelain mixing dish at 4°C is 2 to 3 minutes. The mixing dish is equipped with a thermometer.
The setting time at 37°C is 5 to 10 minutes.
Failures when using C&B Metabond are highly unusual. Should this occur please check if
- the cement being mixed in the correct proportion
- the liquids expired or evaporated. Never forget to re-cap the containers immediately after use
If the problem persists consider priming with the C&B Metabond Dentin Activator
Yes. Predicta® Bioactive Bulk contains 9.25 g of material for a retail price ranging between €105 (€11.35 per g) and €129 (€13.98 per gram). Its larger syringe size, dual-cure chemistry and ability to restore deep preparations up to the occlusal surface can make it a practical, cost-conscious bulk-fill composite for dental practices.
