FILE - In this March 30, 2013 file photo more than 100 patients of Dr. W. Scott Harrington line up outside the Tulsa Health Department North Regional Health and Wellness Center to be screened for hepatitis and the virus that causes AIDS, in Tulsa, Okla. A Tulsa-area patient whose hepatitis C diagnosis led Oklahoma to close two dental clinics, has sued Dr. W. Scott Harrington, claiming the dentist deliberately used rusty instruments and re-used contaminated drug vials leading to the infection. Health officials shut down Harrington’s practices last year, and the investigation into the clinics continues. (AP Photo/Tulsa World, James Gibbard, File) ONLINE OUT; TV OUT; TULSA OUT
