I get postoperative sensitivity when I use total-etch 5th-generation adhesives in restoring root surfaces; should I be using a 7th-generation adhesive?

Most likely, post-operative sensitivity can be rectified if you use a 6th- or 7th-generation, or a “self-etching” adhesive. In total-etch adhesives, the smear layer is removed and the tubules are exposed completely, which can cause sensitivity due to fluid flow within the incompletely filled tubules. With 6th- and 7th- generation adhesives, the smear layer is not removed, but modified, and the demineralization occurs simultaneously with the priming step, so there is not the chance of a void between demineralized dentin with unfilled tubules and resin. I would highly recommend using a 6th- or 7th-generation adhesive in Class V situations. Some of the ones that are rated the highest by the dental advisor can be seen in the Product Comparison Tables for adhesives located on our website.
