A Connecticut dentists' license was revoked after he attempted to extract 20 teeth from the mouth of a 64-year-old woman in one sitting, leading to her death.
Rashmi Patel, who runs two clinics in Enfield and Torrington, was performing the procedure on Judith Gan when she lost consciousness on February 17, Press Trust of India reported.
The procedure included placing implants in the woman's mouth after removing the teeth, according to the New York Daily News.
After repeatedly requesting Patel to stop the procedure, his assistant called the emergency services, NYDN quoted him as saying.
"He wanted to complete the placement of implants as the assistant begged Patel to stop working, and finally ran out and called 911, but the patient had already flat-lined," the state Department of Public Health wrote in a report.
"The four count petition found, among an array of other misdeeds, that Patel deviated from standard of care in that he did not timely and properly respond to Gan's oxygen desaturation and/or respiratory distress and/or cardio-pulmonary distress," state records reported.
"Gan did not have to die to receive this dental treatment and it is because of Patel's negligence that she died," said a dentist who was asked to review the case for the Department of Health.
Patel's license, issued in 2003, was suspended on April 21 pending a June 18 hearing in front of the state dental commission, according to PTI.
"Patel has been ordered to stay away from his patients after one died and another spent six days in the hospital," the state health officials said.
In 2009, Patel was sued for malpractice by a former employee after he performed "shoddy" dental work.
Winning nearly $500,000 from a jury in 2011, an appeal to the ruling eventually ended with an out-of-court settlement, PTI reported.
Both clinics remain open and Patel will fight the charges, the dentist's attorney said.
