I’ve noticed these also. I kind of like them on the border of the prep-an etched mini bevel perhaps. These disappear after application of etch and BA. In my experience the remaining ones that don’t disappear immediately upon contact with moisture have been gone a couple days later when the patient has returned for other work. Sure am less worried about these than the microfractures a bur causes. Anybody else find this to be true?
How about a little dab of topical fluoride gel on the etched ding?
