Self-etch bonding systems

Self-etch bonding systems provide a less sensitive approach to adhesion to dentine than etch-and-rinse systems. They have the additional advantages of using a simpler technique and therefore reduced application time [15]. As we have seen, self-etch bonding agents are available as one-step and two-step systems.

The acidity of self-etching primers allows them not only to penetrate the smear layer and incorporate its component, but also to interact with the underlying intact dentine. In doing so, it forms a hybrid layer of the type previously identified with three-layer bonding systems [20,21], and which is essential in promoting adhesion. This acidity varies between formulations, and can be classified as either strong or weak, depending on the acid involved in the blend and also its concentration [25].
