So what did they expect?

Researchers in Portland, Oregon, found out that when people lost Medicaid dental benefits...they went to the dentist less, their dental health suffered, and they used the emergency room more often. On the one hand, I want to say, Well, wasn't this obvious? Why did you bother? On the other hand, I'm assuming this was done so that health-care activists would have some data to use in their arguments. In the meantime, the cavities yawn wider.
