This is an image of Desmond D'Mello, the Nottinghamshire dentist suspended amid claims he kept medical equipment in the staff toilet and failed to wash his hands or change his gloves between patients.
Around 22,000 patients treated at the clinic are being urged to come forward for tests for blood-borne viruses including HIV and Hepatitis B and C.
Health chiefs have launched a public appeal to trace every patient who has been treated by Mr D'Mello, who ran the Daybrook Dental Practice in Gedling, during his 32-year career.
It is believed to be the biggest recall in British history.
NHS England has posted a video online explaining its appeal for the patients of a dentist to come forward.
Mr D’Mello was secretly filmed at a dental practice in Nottingham allegedly breaching infection-control standards that "horrified" health experts.
A recall of 22,000 patients has been issued by NHS England and a helplinehas been set-up.
Nottinghamshire Police has confirmed it is investigating whether there is a connection between a woman's death and the dental treatment she received from Desmond D'Mello.
The force said it found no link between the death of a second woman and her treatment at the former Daybrook Dental Surgery.
We are making further enquiries, on behalf of the Coroner, into the death of a woman in August 2013.
The 23-year-old had received treatment at the former Daybrook Dental Surgery, in Mansfield Road, earlier that month. Detectives are now working to establish if there are any links between the death and the dental treatment she received.
A dentist who has sparked a major public health alert allegedly stored medical equipment in the toilet.
A inspection by the Care Quality Commission in July this year found that Desmond D'Mello used the staff toilet and the room next to the toilet as store rooms for equipment.
"This posed a risk of these items coming into contact with body fluids which may be contaminated," the report said.
"This risk had not been identified by staff at the dental surgery and no action had been taken to minimise it."
Two female patients in their twenties died shortly after their treatment by Desmond D'Mello, the General Dental Council said following a hearing in August.
One of those patients died as a result of a viral infection, a committee was told.
The council said police have been informed about the deaths.
An appeal was launched today to trace more than 22,000 patients who have been treated by D'Mello amid allegations he did not follow correct procedures.
A dentist whose apparent failure to follow hygiene standards may have put thousands of patients at risk of infection was suspended in June this year.
Desmond D'Mello was suspended after a whistleblower, worried about the standards of care, secretly filmed him allegedly breaching standards at the practice he ran in Nottinghamshire.
The NHS launched an an immediate investigation into "apparent multiple failures in cross-infection control standard whilst undergoing dental treatment".
The findings are yet to be reported.
The former Daybrook Dental Practice has been under new ownership by Southern Dental since August this year.
A helpline and walk-in clinic have been set up for dental patients who have been treated by Desmond D'Mello who allegedly did not follow correct hygiene procedures at a practice in Nottingham.
Patients can contact the helpline on 03330 142479, which is staffed 8am to 8pm, seven days a week.
A community clinic has also been set up at the Arnold Health Centre in the Highcroft Medical Centre on the High Street in Arnold, Nottingham.
The MP for Gedling and the Leader of the Council have said the findings of the report are "shocking and disturbing".
A recall of 22,000 patients has been issued by NHS England who have been treated by a dentist in Nottingham accused of poor hygiene standards.
There are still significant questions that remain about the chronology and management of these events. It is clear to us that a full independent investigation is required to ensure that lessons are learned for the future. We have asked for an urgent meeting with the Secretary of State for Health and will seek assurances of behalf of Gedling residents that everything possible is being done to resolve these very worrying and urgent matters.”
NHS England are appealing for anyone who was treated by a dentist who is accused of poor hygiene standards to come forward for testing.
Desmond D'Mello, who worked at Daybrook Dental Practice in Nottingham, allegedly failed to wash his hands and change gloves when treating different patients.
He is also alleged to have used the same instruments on patients without sterilising them.
"If there had been any transfer of blood between patients due to the lapse in infection control procedures there could potentially be a low risk that hepatitis B, hepatitis C and HIV virus could have been transferred from patient to patient," health officials said.
The recall has been sparked by concerns over a dentist who treated more than 22,000 patients over a 32-year period in Nottingham.Read the full story ›
