I'm sorry but I really don't have any information you require about dentists who treat cavitations. I found a dentist in my area who works in an Amalgam free practice and I have had one of those 'paramex' scans which showed no problems so have not done any more about it. I would post your question in all the forums related to dental probs and also Dr Vinograd's as I am sure someone will be able to give you the info you need.
