Cleaning the Residues & Optimizing your Cementations
After the removal of the temporary crown before cementing a restoration, traditional cleaning methods of the abutment may not be enough for removing residual temporary cement which will reduce the bond strength. KATANA™ Cleaner has a high cleaning effect due to the surface active characteristic of MDP Salt, which is formed from the phosphate monomer "MDP" and an alkaline compound. It is a simple way to optimize your cementation procedures and recover the bond strength.

Test conditions
Adhesion surface treatment: 1 ) Polishing #1000 bovine teeth, 2 ) Temporary Crown (acrylic self-curing resin) was cemented with temporary cement (zinc polycarboxylate cement), 3 ) Stored at 37°C and 95% RH for 1 week, 4 ) Temporary Crown was removed and the temporary cement was removed with an ultrasonic scaler, 5 ) Rubbing with KATANA™ Cleaner for 10 s (upper images)/Water rubbing for 10 s (lower images).

Improving the Bond Strength
As shown on the graphs below, removal of the residual cement either with an ultrasonic scaler or pumice paste & prophylaxis cup may not be enough. After cleaning with KATANA™ Cleaner, its high cleaning effectiveness contributes for an optimized bonding surface.

Test conditions
Adhesion surface treatment: 1 ) Polishing #1000 human teeth, 2 ) Temporary Crown (acrylic self-curing resin) was cemented with temporary cement ( polycarboxylate type, resin-based), 3 ) Stored at 37oC 95% RH for 1 week, 4 ) Temporary Crown was removed and the temporary cement was removed with an ultrasonic scaler or pumice paste and prophylaxis cup at low revolution ( 5000 rpm, 10 s), 5 ) Cleaning with KATANA™ Cleaner.
Bonding strength measurement: 1 ) SUS chip (3mmφ) was bonded by each bonding operation (PANAVIA™ SA Cement Universal, CLEARFIL™ Universal Bond Quick /PANAVIA™ SA Cement Universal, PANAVIA™ V5), 2 ) Measured after storage in water at 37oC for 1 day.

Conclusion
Appropriate cleaning of the residual temporary cement before cementing a restoration is crucial for adequate cementation. KATANA™ Cleaner’s high cleaning effect removes contamination to optimize your cementation procedures.
