Keep in Mind this was the first research haley did and he was a chemistry professor NOt a dentist. I guess the former head of the entire chemistry department is mistaken as well? I really haven't formed an opinion on the overall safety of RC treatment because my concern is more about amalgam but I can see where the controversy is. YOu also haven't given a straight answer about the diagnostic capabilities of x-rays, NOtice how the AEE even admits they are virtually useless for diagnosing NICO legions, and I guess x-rays can determine the bacterial counts in root canals too?

Just curious, How did you measure "clinical outcome". It's hard for me to imagine a study follwing a patient for a long time or having a meaningful way of measuring health effects. In fact even many people who get really sick from infection from poor dental work and have posted here are usually misdiagnosed initially.

Can you quote any controlled studies done by the NIDCR, NIH, AEE, ADA etc. This also holds true for amalgam where NO large studies have been done. It's pretty easy to say, look there are no controlled studies when no one does them.

The usual criteria for clinical success are retention of the tooth without symptoms, and with neither clinical nor radiological evidence of pathosis. Mind you, I'm not commenting on theoretical late sequellae of disseminated disease viz. focal infection. I'm talking about local signs of disease that can be clearly linked to a failed root canal.
