7th Generation bonding agent suitable for total-etch, self-etch, or selective-etch modes
3M™ ESPE™ Adper™ Single Bond 2 Adhesive is a highly advanced dental bonding agent designed for a wide range of dental applications. This adhesive builds upon the success of the original Adper Single Bond adhesive, offering a total etch, visible-light activated formula enriched with a 10% weight of 5nm diameter silica filler. It is primarily intended for direct light-cured restorative procedures and addressing cervical sensitivity. Moreover, it can be effectively employed in bonding laboratory-made composite or porcelain veneers when combined with RelyX™ Veneer Cement and for securing amalgam and other indirect dental applications in conjunction with RelyX™ ARC adhesive resin cement.
Adper Single Bond 2 Adhesive comes in two convenient options, either as a vial with a unique translucent design for visual inspection or in a hygienic unit dose delivery system, simplifying the application process. Its composition comprises key components like BisGMA, HEMA, dimethacrylates, ethanol, water, and a specialized photoinitiator system, along with a polyalkenoic acid copolymer known for its moisture resistance properties. The inclusion of nanotechnology is a notable feature, with 5 nanometer-diameter silica particles ensuring stable suspension without the need for frequent shaking, distinguishing it from adhesives with larger filler particles prone to settling.
This adhesive achieves its strong bond through a micromechanical process, involving the demineralization of enamel and dentin surfaces with a phosphoric acid treatment.
Indications:-
All direct, light-cured bonding procedures.
Indirect bonding procedures when combined with 3M™ ESPE™ RelyX™ ARC Adhesive Resin Cement.
Root surface desensitization.
Porcelain and composite repair.
Bonding veneers in combination with RelyX™ Veneer Cement from 3M ESPE.
Special cap for minimum evaporation
Maintains bond strength – Outstanding shelf life
Excellent shear bond strength provides exceptional bonding performance
Nanofiller is stable and will not settle out of dispersion
Cap snaps securely shut minimizing evaporation
Ethanol/water-based adhesive maintains its shear bond strength over time to yield an outstanding shelf life
Convenient squeeze bottle delivery with attached “pinch & flip” cap for less mess and less waste
Translucent bottle makes it easy to see how much adhesive is left

Isolation: Rubber dam is the preferred method of isolation.
Cavity preparation: Prepare cavity with minimal tooth reduction. Bevel cavosurface enamel margins.
Etching: Apply Scotchbond Etchant to enamel and dentin. Wait 15 seconds. Rinse for 10 seconds. Blot excess water using a cotton pellet or mini-sponge. The surface should appear glistening without the pooling of water.
Adhesive: Immediately after blotting, apply 2-3 consecutive coats of adhesive to etched enamel and dentin for 15 seconds with gentle agitation using a fully saturated applicator. Gently air thin for five seconds to evaporate solvents. Light cure for 10 seconds.
Restorative placement, cure, and finishing: Refer to the manufacturer’s instructions for the placement, cure, and finishing of restorative materials.
