John,
What are your thoughts about micro etching with 50 micron aluminum oxide prior to using Surpass. I've heard that micro etching increases bond strengths even more. What are your thoughts?

Smoother surfaces bond better. 50 micron Al203 consumes enamel at a fast rate and microetching of dentin does not improve bond strengths, and it can lower them.

Does the increase in the surface area of the enamel after microetching not increase the bonding strength to enamel from a mechanical standpoint?
