Gum recession treatment, where we have recession, where the root surface has been damaged, and we use tooth colored filling materials to prevent further damage, providing there's adequate amount of remaining good tissue supporting the tooth. In areas where there's minimal of good healthy tissue protecting the neck of the tooth, then we do gum surgery procedures to regenerate new gum in those areas. That's called a connective tissue graft, or subepithelial connective tissue graft, that's very popular. It's very effective and changed, again, cosmetically the way people look.
You have one end, you have the gum [inaudible 00:00:40], and the other end you have severe recession, making them very uncomfortable with their smile. This really can make a significant difference. These are the new procedures we're looking forward to, hopefully, in the short near future, incorporating the pinhole technique, which is a totally new technique, totally new approach to us to make it less invasive to effectively change the way the gums are shaped around their teeth.
