WALES: Watchdog to check on dentist scare.
The announcement came yesterday after fears not all former patients had received letters inviting them to have blood tests for hepatitis B, hepatitis C and HIV.
The fears were raised by a Gwynedd community health council.
However, the National Public Health Service for Wales and Gwynedd Local Health Board said they have sent letters to everybody who should be contacted and for whom there are records.
NPHS spokesman Chris Lines said: "There is no evidence that anybody has been infected by this health care worker when in the worker's premises.
"The risk is very low and this has been done on a precautionary basis.
"We can't guarantee we have contacted everyone."
Although hundreds of patients have had blood tests at one of 47 clinics specially set up there are fears not all family members treated by the dentist have received letters.
One former patient said: "We used to go as a family, the children went, but out of the four of us only two have received a letter."
Another said: "The children haven't received letters. They haven't been very fair with us."
News the dentist was infected with the virus first broke on May 13.
