General Anaesthesia & Deep Sedation
Whether the clinic documents treatment under general anaesthesia or deep / twilight sedation — "sleep dentistry", where the patient is asleep and unaware (does not feel, see, or hear the procedure). 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 Anesthesia-options page describes twilight IV sedation: 'puts patients into a sleeplike state' and 'some patients may be asleep while others will slip in and out of sleep', alongside conscious nitrous/oral options.
