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 Own site explicitly offers general anaesthesia and IV sedation with 'no re-collection of dental treatment'; calls it sleep dentistry. [s1]
Summary
