The search is on for 7 THOUSAND patients of what might be the world’s worst dentist.  Authorities say Dr. Wayne Scott Harrington of Tulsa, Oklahoma apparently have exposed his patients to HIV and Hepatitis B and C because of his filthy office habits.

The problem came to light when a patient recently tested positive for hepatitis C and HIV.  The patient’s only risk factor was receiving dental treatment from Harrington. 

Upon investigating his office, they found a chamber of horrors including:  regular use of a rusty set of instruments on patients with known infections; attempting to sterilize the instruments with household bleach instead of medically-accepted methods; and his practice of pouring bleach on oral wounds until they "turned white."

Drug cabinets were unlocked and unsupervised.  Medications were out of date, including one drug vial that expired 20 years ago in 1993.

Harrington allegedly re-used intravenous needles.  His records indicated the use of morphine, even though he hadn’t ordered any from his supplier for 4 years.

Harrington was a “Medicaid” provider.  That’s the American public insurance system for low-income people.  It means that Harrington had a larger than average proportion of patients with hepatitis and HIV.
