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.

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