More than 22,000 patients in Nottingham are being urged to get tested for HIV due to a risk of being infected by a virus after being treated by a dentist in the area.
The dentist, who has been named as Desmond D’Mello, is said to have worked in the Nottingham area for over 32 years.
Patients will need to be tested for HIV, Hepatitis B and Hepatitis C.
The recall is believed to be the biggest recall of patients ever to occur in the history of the UK healthcare system.
Now under new ownership, the practice concerned has been named as the Daybrook Dental Surgery on Mansfield Road.
Pending the start of an investigation, Mr D’Mello was suspended for 18 months on August 21 by the General Dental Council.
An advice line has been set up for the patients who may have been treated by Mr D’Mello.
The line is open every day from 8am to 8pm on the number 03330 142479.
Advice, counselling and blood testing will be available at a clinic that has also been set up at the Arnold Health Centre.
The clinic will be open every day from 8am to 8pm.
Although Mr D’Mello is not HIV positive himself, patients are being urged by NHS England to get tested in any case.
