3M Adper Single Bond 2, Total-Etch Dental Adhesive
A total-etch, light-activated dental bonding adhesive formulated for high dentin bond strength when placing direct composite restorations.
Adper Single Bond 2 is a total-etch adhesive system used by restorative dentists to bond composite material to both enamel and dentin during a direct filling procedure. As a total-etch adhesive, it is used after the tooth surface has been etched with phosphoric acid and rinsed, following the conventional etch-and-rinse workflow that many practices still rely on for restorations where predictable dentin bonding is a priority.
The product is light-activated, cured with a standard dental curing light once applied, and is described as offering high dentin bond strength, which supports the durability of the finished restoration under normal chewing forces over time. Reliable dentin bonding matters particularly on posterior restorations and larger cavity preparations where more of the bonding surface is dentin rather than enamel, since dentin bonding has historically been more technique-sensitive than bonding to enamel alone.
Adper Single Bond 2 has been a long-standing product in general and restorative dental practice for direct composite work, and while the manufacturer continues to transition its adhesive range under the Solventum name, this listing reflects the established Adper branded version still referenced by many practices.
