Bonding systems and RXU application procedures.

Optibond FL; 3-step Etch and Rinse	(1) Apply 37.5% phosphoric acid to dentin surface for 15 seconds.; (2) Etchant rinsed with air and water spray for 20 seconds.; Gentle air drying for 5 seconds. Care taken not to desiccate the dentin.; (3) Apply OptiBond FL Prime (Bottle #1) to dentin surfaces with a light scrubbing motion for 15 seconds. Gently air dry with the high-volume suction for approximately 5 seconds.; (4) Apply OptiBond FL Adhesive (Bottle #2) overexposed dentin uniformly creating a thin coating.; (5) Light cure for 20 seconds.; (6) Application of RelyX.
One Coat Bond; 2-step Self-Etch	(1) Apply self-etching primer for 20 seconds applied with rubbing motion to dentin surface.; (2) Air dry for 2 seconds.; (3) Apply Bond for 20 seconds applied with rubbing motion to dentin surface.; (4) Air dry for 2 seconds.; (5) Light cure for 20 seconds.; (6) Application of RelyX Unicem.
Single Bond; 2-step Etch and Rinse	(1) Apply 37.5% phosphoric acid to dentin surface for 15 seconds.; (2) Etchant rinsed with air and water for 20 seconds.; (3) Dentin-blotted dry of excess water.; (4) Apply 2 consecutive coats of single bond for 15 seconds each with gentle agitating.; (5) Air dry for five seconds to evaporate solvent.; (6) Light cure for 20 seconds.; (7) Apply RelyX Unicem.
Go!; 1-step Self-Etch	(1) Clean and blot dry tooth surface.; (2) Apply to dentin for 20 seconds.; (3) Air dry for 5 seconds.; (4) Light cure for 10 seconds.; (5) Apply RelyX Unicem.
RelyX Unicem (RXU)	(1) Clean tooth surface with pumice and water.; (2) Air dry 2-3 seconds to remove pooled water.; (3) Apply RelyX Unicem.
