A state official says it could be several more months before an investigation of a Tulsa-area oral surgeon accused of exposing more than 7,000 patients to hepatitis C and B, and HIV is finished.
Oklahoma Board of Dentistry Executive Director Susan Rogers says her office continues to receive complaints from former patients of Dr. W. Scott Harrington. She says a criminal case against him is still possible.
State health inspectors shut down Harrington's clinics in Tulsa and Owasso March 28 after finding unsanitary conditions.
A 17-count complaint filed by the state said officials found rusty instruments, potentially contaminated drug vials and improper use of a machine designed to sterilize tools at Harrington's two Tulsa-area offices.
Last month, investigators said Harrington was responsible for the nation's first transmission of hepatitis C between patients in a dental office.
Dr. W. Scott Harrington's attorney told the News On 6 in September his client is ready to defend himself against the dental board's attempt to take away his license.
The Oklahoma Board of Dentistry will decide if Harrington will be allowed to practice in the state again. A hearing is scheduled for January 2014 to decide that matter.
