In the documents released by the state, Dr. Stein has agreed to give up his professional license.

The board accuses Dr. Stein of writing prescriptions for patients for drugs like Vicodin and Vicoprofen and then telling them to bring the prescription drugs to the clinic. He would then use the drugs for personal use, reportedly.

The board claims Stein was impaired while practicing dentistry. Stein is accused of saving unused drugs in syringes and then combining those drugs into another syringe that would be used on another patient.

After receiving that accusation, the Colorado Department of Public Health looked into the matter and found there were five positive lab tests of his previous patients.

According to the CDPHE, it is unknown at this time whether those infections are directly related to Dr. Stein's dental practice.

Stein went to rehab for chemical and substance abuse in 1998.

The time frame for potential infections is from 1999 to 2011.

Dr. Stein's former patients were tested for Hepatitis B, Hepatitis C and HIV. It is unknown at this time what the three positive cases tested positive for.

"The CDC and department confirmed it would be difficult if not impossible to conclude definitively whether the dental practice was the actual source of transmission for any of these positive test results," the CDPHE said in a release sent out in early August.

Dr. Stein is accused of re-using needles and syringes for days at a time on his patients over the course of 12 years. He had two practices - one in Denver and one in Highlands Ranch.

A 9NEWS viewer - who wanted to remain anonymous - says her husband tested positive for Hepatitis C after a major health warning from Colorado's Public Health Department.

The positive lab results for Hepatitis C shown to 9NEWS came nearly two weeks after 8,000 people received letters from Colorado's Health Department about oral surgeon Dr. Stein.

The 9NEWS viewer's husband went to Dr. Stein for several procedures. His last procedure, done in September 2009, Dr. Stein pulled her husband's wisdom teeth, she says.

She received a letter from the state, much like many of Dr. Stein's other patients, saying her husband should be tested, she said.

The positive results for Hepatitis C came from her husband's doctor's office, and they ordered further testing. Hepatitis C is an infection caused by a virus that attacks the liver and leads to inflammation.

"Most people infected with the Hepatitis C virus (HCV) have no symptoms," according to the Mayo Clinic's website. "In fact, most people don't know they have the Hepatitis C infection until liver damage shows up, decades later, during routine medical tests."

The 9NEWS viewer said tests for HIV and Hepatitis B came back negative for her husband.

A nurse at her husband's doctor's office said there was no definitive way to link the positive Hepatitis C results to Dr. Stein's practice, she said.

Past patients may have been put at risk if they were seen by Dr. Stein during these time frames and at these locations:

  • September 1999 to June 2011 at Stein Oral and Facial Surgery, 8671 S. Quebec St., #230, Highlands Ranch, CO 80130
  • August 2010 to June 2011 at Stein Oral and Facial Surgery, 3737 E.1st Ave., Suite B, Denver, CO 80206. Patients also were seen by Stein at this location but under the name, New Image Dental Implant Center.
