The dentist, identified as Dr. Byron Wong, 37, has voluntarily stopped his practice, and is co-operating with the health authority to ensure all patients are contacted, Dr. Jonathan Skuba, president of the Alberta Dentist Association and College, told a news conference Tuesday afternoon.2 S$ W8 }8 n% K# E3 n

Dr. Gerry Predy says the risk of infection to Byron Wong's patients is very small. (CBC) * W7 O) s( F+ x; D0 i G
"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."6 j. J3 @( m- ]$ O; o3 T( z$ o. Y

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.8 ~7 ? r; ^1 Y4 A; d1 F& A9 ~& R( g

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. _- i0 \% ~3 I( T' H' c

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. |
