INTRODUCTION

Adhesive dentistry has seen significant advancements over the past decades. Initially, dental adhesives evolved from no-etch systems to etch-and-rinse systems, which consisted of multiple components. From then on, manufacturers shifted focus toward simplifying the procedure. Different generations of self-etch adhesives and, finally multi-mode or universal adhesives were the result. The latter category, introduced in the early 2010s, nowadays comprises numerous products offered by many different manufacturers.

In general, universal adhesives offer more procedural freedom and simplicity than multi-step, multi-bottle systems as well as good adhesion. According to a recent review¹, adhesive properties have improved and manufacturers have also succeeded in reducing the technique sensitivity of the adhesive systems. However, hybrid layer degradation still seems to be a relevant issue for many modern products available on the market. Moreover, feedback from clinicians reveals that there are several areas of concern where bonding systems in general can be improved. These include the risk of contamination due to a lengthy procedure or the need for rubbing, pooling of the adhesive in corners and accumulation along margins. Moreover, some adhesives are challenging to introduce into narrow cavities, while their curability may be limited.

That is why Kuraray Noritake Dental Inc. decided to develop a new-generation universal adhesive that addresses these areas of concern: CLEARFIL™ Universal Bond Quick 2. This latest evolution in dental bonding technology is based on decades of knowledge in the development of clinically successful dental adhesives at Kuraray Noritake Dental Inc. It retains all the benefits of its predecessor – the current extensively tested and clinically proven CLEARFIL™ Universal Bond Quick – adding higher strength and improved handling.^2-5

THE ESSENTIAL BENEFITS OF CLEARFIL Universal Bond Quick 2

CLEARFIL Universal Bond Quick 2 offers the following essential benefits:

• Quick and straightforward application procedure
• High-strength bonding layer
• Consistently durable bond
• Ease of application
• Minimised risk of pooling
• Procedural freedom
• Immediate availability for clinical use

For all those who wonder how the improvements were implemented, which technologies are responsible for them and whether there is scientific proof, the following paragraphs are worth reading. They summarize essential general knowledge about adhesive formulations, explain potential issues and their causes, and address every benefit featured by CLEARFIL Universal Bond Quick 2, explaining all the important details around it.

KEY COMPONENTS OF UNIVERSAL ADHESIVES

Universal adhesives are based on highly complex formulations with many different constituents and technologies combined in a single bottle. The most essential parts found in virtually every universal adhesive are:

RESIN COMPONENTS

Just like composite restorative materials, dental adhesives are resin-based materials. This means that different kinds of cross-linking and functional monomers are the beating heart of the formulation. Functional monomers are initially hydrophilic and form linear polymers upon curing, while cross linking polymers are hydrophobic and form stronger, highly cross-linked polymer networks.⁶ They are added to adhesive formulations to fulfil different tasks: some monomers are used to promote adhesion to tooth structure or composite resin, while others are used as etching or demineralizing agents, wetting enablers, and agents promoting penetration into the tooth structure. Hence, they have an impact on application properties, bond strength to various substrates including enamel and dentin, strength, hydrolytic stability and overall durability of the bonding layer, and more.

Case by DT Andreas Chatzimpatzakis and Dr Evi Lianou

Selecting the right materials for a successful rehabilitation of edentulous jaws with fixed implant-based prostheses can be quite challenging. High strength and stability are needed to securely connect the implants, biocompatibility is a must and the functional, aesthetic and financial expectations of the patient need to be respected. Experience shows that – in many situations – the combination of a titanium bar with a zirconia framework finished using the micro-layering technique is a great option. This material combination and approach meets the demands mentioned, while supporting efficient procedures and aesthetic outcomes.

In the present case, a 53-year-old male patient with a history of periodontal disease presented in the dental office of Dr Evi Lianou (Dental Clinic, Lamia, Greece). Due to a poor prognosis of the remaining teeth, it was planned to extract them. As a removable full denture was not an option for the patient, the treatment plan included the insertion of four implants in the mandible and six in the maxilla, followed by a healing phase and subsequent definitive rehabilitation with screw-retained, titanium bar-based zirconia superstructures finished by micro-layering. The following figures and captions describe the technical procedure.

CONCLUSION

The described material combination and technique allows for efficient workflows, while supporting aesthetic, durable treatment outcomes. With functional surfaces designed in plain, polished zirconia and just a tiny layer of porcelain in the vestibular region, the restorations are made to last. Moreover, the selected framework material and porcelain system are a perfect match.

The chosen porcelain system works well with other zirconia brands and even with lithium disilicate. It can be used with or without internal stains, making it a versatile tool suitable for a wide range of applications, patient needs, and aesthetic demands.

REDEFINING WHAT “UNIVERSAL”  MEANS

When discussing the universal properties of a dental adhesive, most of us probably think of its compatibility with various etching techniques (from self-etch to total-etch) and a wide indication range. After all, universal adhesives are typically used as bonding agents for direct restorations made of light-curing composite, for immediate dentin sealing, for repair procedures and also in the context of indirect restoration placement.

However, in our opinion, there is more to it:

This means it should be compatible with any resin-based composite and self-adhesive resin cement, regardless of the manufacturer.

BREAKING FREE FROM SYSTEM BOUNDARIES

This is not self-evident: For a long time, “staying within the manufacturer’s own system ” has been a key prerequisite for the successful use of dual-cure core build-up materials and self-adhesive resin cements. Manufacturers worldwide have strongly recommended combining components from the same manufacturer and system to provide for chemical compatibility, optimal alignment, and the best possible outcomes. 

CLEARFIL™ Universal Bond Quick 2: FREEDOM AND FLEXIBILITY

With the new CLEARFIL™ Universal Bond Quick 2, this is no longer necessary: The R&D team of Kuraray Noritake Dental Inc. in Japan has developed an adhesive that works well not only with the company’s self-adhesive resin cement PANAVIA™ SA Cement Universal, but also with other manufacturers’ products. The same applies to core build-up materials: Compatibility is no longer limited to CLEARFIL™ DC CORE PLUS, but extends to solutions offered by other companies. Thorough testing has confirmed that it works well – provided each product’s official instructions for use are followed.

ONE ADHESIVE FOR EVERY CHALLENGE

This makes CLEARFIL Universal Bond Quick 2 a truly universal adhesive and, in fact, the only one needed in your dental practice. Interested? Learn more about the product and its innovative features, including its effortless application with no waiting time.

Case by Dt. Koray Kendir, DDS, Turkey (İzmir)

INTRODUCTION

Trauma-related fractures of anterior teeth require a precise balance between aesthetics and function, often under emotional pressure from the patient. This clinical case demonstrates the restorative rehabilitation of a previously mismanaged central incisor using CLEARFIL MAJESTY™ ES-2 Premium and PANAVIA™ V5 (both Kuraray Noritake Dental Inc.). The team worked to re-establish biological, functional, and aesthetic harmony.

CASE SUMMARY

A 23-year-old female patient presented one month after a traumatic injury involving tooth #11 (FDI notation). Immediate root canal treatment and a direct composite build-up had been performed elsewhere in a single visit. The existing restoration showed poor aesthetics and marginal adaptation (Fig. 1).

Fig. 1. Initial clinical situation.

CLINICAL PROCEDURE

STEP 1: ISOLATION AND REMOVAL OF OLD RESTORATION

For the planned rehabilitation, the tooth was isolated with rubber dam (Figs. 2 and 3) and the existing composite restoration was removed. Gutta-percha from the previous endodontic treatment was found to be severely coronally trimmed (Fig. 4). This poses a risk of future discolouration. Consequently, the gutta-percha was condensed apically to a more biologically appropriate level using a downpack device (Figs. 5 to 9).

STEP 2: CORE BUILD-UP

Subsequently, a fiber-reinforced composite was used to provide root-anchored support for the core structure. Then, the bonding surface was treated with phosphoric acid etchant, CLEARFIL™ Universal Bond Quick (Kuraray Noritake Dental Inc.) was applied as a universal adhesive and the core build-up was performed with CLEARFIL MAJESTY™ ES-2 Premium A1D (Figs. 10 to 13).

Fig. 13. Intra-oral periapical radiograph or the treated tooth.

STEP 3: PREPARATION AND DIGITAL IMPRESSION

For definitive restoration, a 3/4 crown preparation was performed and an intraoral scan was taken. Moreover, a temporary crown was fabricated (Fig. 14) and shade photos were taken to finalize the session.

Fig. 14. Temporary restoration in place.

STEP 4: FINAL CEMENTATION

Once the lithium disilicate restoration was received from the laboratory, the temporary crown was removed and the abutment tooth was evaluated (Figs. 15 and 16). Try-in was performed using PANAVIA™ V5 Try-in Paste White to check shade and fit (Fig. 17). No modifications were required; the selected try-in paste contributed to a lifelike appearance of the restoration. For definitive placement, the intaglio surface of the crown was etched with hydrofluoric acid (Fig. 18). Figure 19 shows the appearance of the intaglio after this measure. To provide for optimal bonding conditions, the tooth surface was then cleaned with KATANA™ Cleaner (Kuraray Noritake Dental Inc.), which should be applied with a rubbing motion to the contaminated prepared tooth for more than ten seconds (Figs. 20 to 22). It may also be used to clean the intaglio of a restoration, which is contaminated with blood and saliva e.g. after try-in.

Fig. 22. Thorough rinsing, which should be followed by drying with air.

Adhesive cementation itself was accomplished with the three-component PANAVIA™ V5 (Figs. 23 to 28): The prepared tooth structure and build-up was treated with PANAVIA™ V5 Tooth Primer, the intaglio surface of the crown with CLEARFIL™ CERAMIC PRIMER PLUS. Finally, PANAVIA™ V5 Universal (White) was extruded into the crown and the crown placed. Excess cement is best removed in the gel phase – i.e. after brief polymerization for 3 to 5 seconds before final light curing is performed. Alternatively, it may be removed immediately after seating the restoration with a brush or similar instrument. In this case the first option was chosen. The treatment outcome after rubber dam removal and final clinical and aesthetic evaluation is displayed in Figure 29.

CONCLUSION

This case highlights a comprehensive restorative approach to preserving a traumatized anterior tooth at risk of loss, while restoring both function and aesthetics. The strong core foundation provided by CLEARFIL MAJESTY™ ES-2 Premium and the reliable adhesive performance of PANAVIA™ V5 played a pivotal role in the successful procedure and outcome.

A SHARED FOCUS ON IMPROVING PATIENT CARE

At Kuraray Noritake Dental Inc., innovation is guided by a clear understanding of clinical realities. The awards received in 2026 reflect an ongoing commitment to developing materials that balance scientific excellence with practical usability – supporting predictable outcomes, efficient workflows and improved patient care. As dentistry continues to evolve, the recognition from the Dental Advisor underscores the importance of solutions that stand the test of time. By listening closely to clinicians and investing continuously in research and development, Kuraray Noritake Dental Inc. remains focused on advancing dental science in ways that matter most – supporting dental professionals in their striving for success and for enhancing their patients’ quality of life, every day.

Dentistry is evolving fast, and so are the expectations of patients and dentists. Nowadays, most dental practitioners know that different zirconia variants are available and that there are certain quality standards the selected material should meet to provide for aesthetic, functional and durable outcomes. Consequently, they often demand the use of a specific zirconia variant for their planned restorations.

Due to the widespread use of Tosoh zirconia in the market, however, many of these dentists are only familiar with the Tosoh 3Y / 4Y / 5Y zirconia terminology. This means that when prescribing a specific type of zirconia, they mention the desired yttria concentration. Unfortunately, this can create confusion in communication between dentists and dental laboratories: Not every zirconia brand and variant on the market fits into this Tosoh classification system.

KATANA™ Zirconia discs of Kuraray Noritake Dental Inc. are made of proprietary powders and advanced multi-layered technology developed in-house. The unique performance these blanks deliver cannot be simply described with the aid of the Tosoh system. Instead, we rely on the internationally recognized ISO 6872 classification — a standard that reflects clinical indications and material performance with precision.

WHY THE ISO 6872 CLASSIFICATION MATTERS

Unlike brand-specific powder classifications, ISO 6872 provides a clear, scientific, and globally accepted framework. It ensures that when a dentist prescribes a solution, or a technician selects a material, everyone speaks the same language – based on strength, translucency, and indication range. 

CONCLUSION

KATANA Zirconia is an advanced dental zirconia family that does not fit into standard boxes like 3Y, 4Y, or 5Y. It redefines what zirconia can do – blending beauty and strength with a scientifically validated ISO classification system. By embracing globally defined and accepted ISO 6872, we can contribute to peace of mind and eliminate confusion in the market.

FLOWABLE INJECTION TECHNIQUE

What are the most important properties of a flowable composite used for the flowable injection technique? Personal experience shows that balanced optical properties are essential, with an appropriate translucency, blend-in ability and surface gloss leading the way. However, the mechanical properties are also important, not least because the restorative material will be in direct contact with the antagonist teeth. And finally, handling properties are essential: The right level of flowability is needed for proper injection, while a void-free application is required for an intact, stain-resistant surface.

For the last seven years, CLEARFIL MAJESTY™ ES Flow Low (Kuraray Noritake Dental Inc.) has been my go-to flowable composite for the flowable injection technique. Its level of flowability is ideal for the technique in the anterior and posterior region. Whenever a lower flowability is needed, it is possible to switch to the Super Low variant. Moreover, I like the shade offering, which – together with the superior polishability of the material – leads to natural aesthetics. Finally, its mechanical properties are so good that the product is approved for a wide indication range without load limitations.

When the company announced the introduction of CLEARFIL MAJESTY™ ES Flow Universal, which comes in just two universal shades and two different levels of flowability (Low and Super Low), I immediately decided to give it a try: The prospect of balanced properties I am already familiar with, combined with a simplified shade selection sounded very promising. So far, the new product comes up to my expectations: The following case example reveals the simplicity of the procedure and the beauty of the results. The patient presented during orthodontic (aligner) treatment for a shape correction in the anterior region due to wear of the incisal edge.

RESULTS THAT SPEAK FOR THEMSELVES

Like its related product CLEARFIL MAJESTY ES Flow, the universal-shade version CLEARFIL MAJESTY ES Flow Universal offers properties which are – from a personal perspective – ideal for the flowable injection technique. The shade-matching properties are astonishing; the translucency is quite high when placed in thin layers (so that enamel is very well imitated), and the polishability is as good as that of CLEARFIL MAJESTY ES Flow. For virtually effortless, bubble-free injection, the product comes in a nicely designed syringe. And last but not least, the product’s mechanical properties provide peace of mind even in the posterior region.

A SMARTER GUIDE TO SELECTIVE DENTIN EXCAVATION

The modern approach to restorative dentistry emphasizes tissue preservation and clinical precision. Instead of extensive removal, today’s clinicians aim to conserve as much sound and remineralizable dentin as possible.

Caries Detector provides a simple yet effective way to achieve this precision by visually differentiating infected from affected dentin during caries excavation.

UNDERSTANDING THE DENTIN LAYERS

Dentin carious lesion is not homogeneous. It can be divided into two distinct zones:

• Infected dentin — irreversibly demineralized and heavily contaminated with bacteria; must be completely removed.
• Affected dentin — partially demineralized but capable of remineralization; should be preserved to maintain tooth vitality and strength.

The difficulty lies in identifying the exact transition between these two layers. Caries Detector facilitates this decision by providing a visual endpoint for excavation.

MECHANISM OF ACTION

Caries Detector selectively stains the infected outer dentin a vivid scarlet red while leaving the affected and sound dentin unstained.

This clear chromatic differentiation allows clinicians to identify residual infected tissue and avoid unnecessary removal of reparative dentin.

Depending on the clinical situation, the material can be used:

• In shallow cavities, prior to cavity opening for assessment.
• In deep lesions, following initial excavation to guide further selective removal while preventing pulpal exposure.

CLINICAL PROTOCOL

1. Preparation – After rubber dam placement, wash and dry the carious tooth.
2. Application – Place one drop of Caries Detector on a disposable brush and apply to the cavity.
3. Reaction time – Allow ten seconds for staining to occur.
4. Rinsing – Rinse thoroughly with water to remove excess dye and reveal the stained areas.
5. Selective removal – Excavate the red-stained infected dentin with a low-speed rotary instrument, avoiding the unstained tissue.
6. Verification – Repeat application if necessary to ensure complete removal of infected dentin.

The procedure yields a clean, sound dentin surface ready for adhesive bonding and restoration.

INTEGRATING WITH MINIMALLY INVASIVE RESTORATIVE WORKFLOWS

Caries Detector represents the first step in a conservative restorative protocol, aligning with the philosophy of minimum intervention dentistry (MID).

When combined with Kuraray Noritake Dental’s range of adhesive and restorative materials, clinicians can achieve:

• Controlled removal of infected dentin 
• Enhanced bonding to sound, remineralizable dentin
• Optimized aesthetic and long-term restorative outcomes

CONCLUSION

By translating histological principles into a practical chairside tool, Caries Detector allows clinicians to perform caries excavation with greater accuracy and confidence.

It supports minimally invasive principles, preserves tooth vitality, and lays the groundwork for durable, esthetic restorations.
