Ordinary conscious sedation, where the patient stays awake and responsive, does not count here. This is informational and does not affect the transparency score.

  • General anaesthesia / deep sedation (sleep dentistry) — General anaesthesia / deep sedation documented Site states surgeons are board certified/eligible in Dental Anesthesiology and that facility/procedure rooms are 'inspected and certified for general anesthesia'.
