Bonding to and protecting worn palatal surfaces of teeth with dentine bonding agents.

Dentine bonding resins may play a role in protecting dentine against acids for patients with erosion. Therefore, it is important to try and understand what potential difficulties may ensue when bonding to worn dentine. This paper reviews the literature on the changes between normal and worn dentine and the effect of this on the bonding to composite resins. A medline search was undertaken using the terms erosion, tooth wear and dentine bonding up until the spring of 2003. Although there are changes on the surface of worn dentine, there is little evidence that this may affect the bond.
