The Barnhart 5/6 is every hygienist’s first love. It’s one of the first instruments we learn in school and then rely on so much to remove sub and supragingival calculus throughout our career. And don’t tell me you haven’t had a dream about scaling teeth with your trusty old Barnhart. Of course, American Eagle Instruments makes one of these trusty instruments with their XP sharpen-free technology. Be sure to head on over to our Facebook page to win one and see it in action in our latest video.
