The majority of dentists do not do sedation dentistry and therefore this regulation is an unnecessary regulatory nightmare for the state to oversee and the average general dentist to have to uphold.  If the dentist does sedation dentistry then I believe the state of Virginia already has requirements over and above the norm to adhere to.  As tragic as these 2 deaths are in recent years, undiagnosed medical conditions are a problem that should be diagnosed and investigated by parents and pediatricians prior to sedation no matter what setting it occurs in.
