Dr. Wong has provided excellent  points and I cannot agree more.  Taking one step forward and two steps back should not be the philosophy of the BOD.  To me liability is a key issue.  To have an anesthesia provider, whether it be a CRNA or an Anesthesiologist, be the only person trained in a Dental office is a set up for disaster.  Moderate sedation can progress to deep sedation very quickly and if an airway situation presents who is going to assist the anesthesia provider if the Dentist has no training.  No one can do this by themselves safely.  I am tired of reading about a bad outcome from anesthesia being provided in a Dental office by people who are not trained.  It reflects badly on the profession.
