Dr. Gerry Predy says the risk of infection to Byron Wong's patients is very small. (CBC)
' M7 d( k5 V" Z7 _/ a"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."

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.
