Public health officials are contacting 1,400 patients of Edmonton dentist Dr. Byron Wong after he tested positive for hepatitis B. (CBC)

Wong approached the college in February, immediately after he was told of the positive test, Skuba said.

"We did a risk analysis of the potential risk of this dentist transmitting the effect to his patient, and the risk is very small. We estimate somewhere 1 in 10,000 to 1 in 100,000, probably close to the 1 in 100,000 figure."! e" o" m5 _4 g" ^' G( x# A- @

Hepatitis B has been part of the province's school immunization program since the mid-1990s, so most people aged up to the mid-20s should be protected, Predy said.

Officials even debated whether to issue a public warning because the risk is so small, but in the end, they concluded people would want to know, Predy said./ h( c5 k" P7 e0 w& Y8 ]

Capital Health will start contacting Wong's 1,400 patients in the near future to offer them hepatitis B tests, a process that was expected to take a couple of months. |
