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) — No general anaesthesia or deep sedation documented Offers oral sedation ('awake and responsive') and IV sedation described as 'deep conscious sedation'; FAQ confirms patients 'remain responsive', not asleep.
