A New Cleaner for a Stronger Bond: Salvaging Saliva-Contaminated Dentin
A new in vitro study investigates a promising protocol for managing a common clinical challenge: saliva contamination during adhesive dentistry. Researchers tested the effectiveness of an MDP salt-based surface cleaner (KATANA™ Cleaner) on restoring the bond strength of composite resin to saliva-contaminated dentin at various stages of a two-step self-etch adhesive procedure. The findings revealed that using the cleaner after saliva contamination, particularly following primer application or even after the adhesive had been polymerized, significantly improved microshear bond strength. In fact, decontamination after primer contamination resulted in bond strength that surpassed the uncontaminated control group.
Why it might matter to you: For endodontic procedures involving adhesive restorations like post-core buildups or final coronal seals, maintaining a perfect isolation field can be difficult. This research provides evidence for a specific decontamination protocol that can effectively rescue a compromised bond, potentially improving the longevity of restorations placed after root canal therapy. It offers a practical, science-backed step to integrate into your workflow when moisture control is less than ideal.
