How can surface cleaning improve bond strength in restorative dentistry?

DENTAL ADVISOR HIGHLIGHTS THE SUITABILITY OF KATANA Cleaner FOR INTRA-ORAL USE

Clean surfaces – whether tooth structure or restorative materials – are essential for reliable and long-lasting adhesion in restorative dentistry. To achieve this, clinicians require a cleaning agent that removes contaminants such as blood or saliva efficiently and thoroughly, without adding complexity to the workflow. KATANA™ Cleaner was developed by Kuraray Noritake Dental Inc. to meet these clinical demands.

 
Recognized with a 2026 Research Award in the category Research – Restoration Cleaner, KATANA Cleaner is a truly universal cleaning solution for both restorations and tooth structure. Designed for intra-oral and extra-oral use, it contains MDP salt, which effectively removes contamination from a wide range of surfaces, supporting bond integrity during adhesive procedures.

 
Key benefits of KATANA Cleaner include:

• High cleaning efficacy based on the surface-active characteristics of MDP salt
• Mild pH value (4.5), allowing effective intra-oral application
• Simple, time-efficient application requiring just ten seconds of surface rubbing 

DENTAL ADVISOR RESEARCH AWARD: RECOGNITION FOR CLEAN SURFACES THAT SUPPORT OPTIMAL BOND STRENGTH

The Dental Advisor Research Team conducted in-vitro testing to evaluate the cleaning performance of KATANA Cleaner and its impact on bond strength with indirect restorative substrates. In these studies, zirconia and lithium disilicate surfaces were contaminated with saliva and subsequently treated with KATANA Cleaner. SEM analysis revealed virtually perfect surface cleanliness, which contributed to optimal bond strength levels. The Research Team also noted that KATANA Cleaner is “one of the few products commercially available that can be used intra-orally...”

SUITABLE SOLUTION FOR MANAGING CONTAMINATION

With its universal applicability, gentle yet highly effective cleaning effect and proven ability to restore optimal bond strength, KATANA Cleaner offers clinicians an excellent solution for managing contamination in adhesive dentistry. Its recognition with a 2026 Dental Advisor Research Award underscores its relevance and highlights its suitability for a wide range of indications.

PART OF EXPANDING UNIVERSAL EXCELLENCE PORTFOLIO

At Kuraray Noritake Dental Inc., we understand the demands of modern adhesive dentistry. Reliable adhesion depends not only on high-performing bonding materials, but also on proper surface preparation and contamination management throughout the workflow.

That is why KATANA Cleaner is part of our expanding Universal Excellence portfolio. Designed for both intra-oral and extra-oral use, it helps clinicians optimize adhesive procedures by efficiently removing contamination from tooth structure and restorative materials.

Supporting clean bonding surfaces in a simple and time-efficient manner, KATANA Cleaner complements restorative workflows involving products such as CLEARFIL™ Universal Bond Quick 2 and PANAVIA™ SA Cement Universal — contributing to predictable and durable adhesion across a wide range of clinical indications.
