It's hard to say. What we have, the December 1995 study, is really a comprehensive study with the best evidence available at that time. I know a lot of crowns. As a lawyer, I would like to believe that the sentiments that were expressed, even at that time, were hopefully not representative of crowns generally. I don't think they are, from the crowns I've met, but I have no way of knowing, and that's part of the issue.
