Description

CLEARFIL S³ BOND is a 7^th-generation bonding system that includes the primer and adhesive in one bottle. This light-cured material is water-based and self-etching. The material must be applied to the tooth for 20 seconds. Strong air and high-volume suction are utilized to evaporate the solvent, and then CLEARFIL S³ BOND is light-cured for 10 seconds. Refrigeration is recommended for overnight or long-term storage. CLEARFIL S³ BOND is available in a kit containing a 4-ml bottle, disposable brush tips, brush tip handle, and accessories. Sixteen editors evaluated CLEARFIL S³ BOND during a six-week period. This product received a 92% clinical rating.

Editors’ Observations

Manufacturer’s Instructions
The technique guides are well illustrated with a clear, simple description of each indication for use. Abbreviated directions are also provided on the side of the bottle for quick reference.

Completeness of Kit
The bottle is small, well-balanced and easy to open. Consultants found the directions printed on the bottle to be an excellent addition. Disposable brushes and a sterilizable handle are provided. Disposable fiber-tipped applicators would be preferred.

Ease of Dispensing/Ease of Use
CLEARFIL S³ BOND has a medium viscosity and is easily dispensed in a controlled volume. The slight yellow color is easy to see, indicating that all surfaces have been covered. The CLEARFIL S³ BOND system is very simple to use and requires a short application time.

Viscosity
The viscosity allows for controlled dispensing and coating of all surfaces; however, it is more difficult to disperse with air.

Initial Postoperative Sensitivity
No sensitivity was reported during the six-week evaluation period of CLEARFIL S³ BOND.

Ease of Matrix Band Removal
The bond strength data is exceptional; however, consultants found it very difficult to remove the metal matrix band after placement of the composite.

Clinical Tips

• Use an instrument such as a spoon excavator to remove cured adhesive from the internal aspect of the matrix band before composite placement.
• Use a phosphoric acid etchant on uncut enamel
