A collective dental shame?

In my time in the medicolegal business I received requests for help in resolving disputes between dentists who worked together, or between a dentist selling a practice and the person purchasing it. They were generally asking for advice from the wrong source, but it left me thinking that dentists often did not treat their fellow professionals with much respect: ok, when running a practice, money has to be involved because the practice has to generate income for its owner and the staff employed in it, but surely it is professional behaviour rather than solely money which should govern what we do and how professionals behave? I also heard recently of an associate who simply left a practice without working any notice, leaving many patients in the lurch, another example of unprofessional behaviour. Surely, unfair or unkind behaviour of one dental professional to another is just about as serious as mistreating a patient?
