Tooth repair
Staff Sgt. Amy Cadavero shapes a porcelain crown using a dental drill with a diamond bur drill bit Sep. 9, 2008, at Eielson Air Force Base, Alaska. Once Sergeant Cadavero receives the impressions made from the patient teeth she will then make it into a cast mold to start shaping the crown so it will fit comfortably in the patients' mouth, this process can take up to a week to finish. She is a dental lab technician assigned to the 354th Medical Operations Squadron. (U.S. Air Force photo/Airman 1st Class Jonathan Snyder)
