Adhesive composition and application procedure (information supplied in the safety data sheets and material instructions).
| Material | pH | Composition | Application Mode | |
|---|---|---|---|---|
| Self-Etch | Etch-and-Rinse | |||
| G-Premio Bond (GPB) GC Corp. Tokyo, Japan P | 1.5 | 10-MDP, phosphoric acid ester monomer, dimethacrylate, 4-MET, MEPS, acetone, silicon dioxide, initiators | 1. The only difference is the dentin drying time: 0, 5, and 10 s 2. Apply the adhesive to the entire preparation without rubbing for 10 s 3. Direct a gentle stream of air over the liquid for about 5 s until it no longer moves and the solvent is evaporated completely |
1. Apply etchant for 15 s 2. Rinse thoroughly for 5 s 3. The only difference is the dentin drying time: 0, 5, and 10 s 4. Apply adhesive as in the self-etch mode |
| Single-bond Universal (SBU) 3M ESPE Seefeld, Germany | 2.7 | 10-MDP, phosphoric acid ester monomer, HEMA, silane, dimethacrylate, Vitrebond copolymer, filler, ethanol, water, initiators, silane | 1. The only difference is the dentin drying time: 0, 5, and 10 s 2. Apply the adhesive to the entire preparation with a microbrush and rub it in for 20 s 3. Direct a gentle stream of air over the liquid for about 5 s until it no longer moves and the solvent is evaporated completely 4. Light-cure for 10 s |
1. Apply etchant for 15 s 2. Rinse thoroughly for 10 s 3. The only difference is the dentin drying time: 0, 5, and 10 s 4. Apply adhesive as in the self-etch mode |
| All-Bond Universal (ABU) Bisco Schaumburg, USA | 3.2 | 10-MDP, phosphoric acid ester monomer, Bis-GMA, HEMA, ethanol, water, initiators | 1. The only difference is the dentin drying time: 0, 5, and 10 s 2. Apply two separate coats of adhesive, scrubbing the preparation with a microbrush for 10–15 s per coat. Do not light cure between coats 3. Evaporate excess solvent by thoroughly air-drying with an air syringe for at least 10 s, there should be no visible movement of the material. The surface should have a uniform glossy appearance 4. Light cure for 10 s |
1. Apply etchant for 15 s 2. Rinse thoroughly for 10 s 3. The only difference is the dentin drying time: 0, 5, and 10 s 4. Apply adhesive as in the self-etch mode |
Bis-GMA: bisphenol glycidyl methacrylate; HEMA: 2-hydroxyethyl methacrylate; MDP: methacryloyloxydecyl dihydrogen phosphate; 4-MET: 4 methacryloxyethyltrimellitate anhydride; MEPS: Methacryloyloxyalkyl thiophosphate.
