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 Own blog states the clinic uses exclusively local anaesthesia for dental procedures. [medstom-dondukov-deepen-4]

2026-09-29Checked TripAdvisor's own search and the clinic's website for a TripAdvisor profile: none found on either channel.
2026-09-29Corrected 2026-09-29: review recency within 3 months (newest review dated 2026-09-21).
2026-09-17Re-read on 2026-09-17: the clinic's two dedicated price-list pages, X-ray page, branch gallery and price page in English, plus its Google listing. Recorded: a full published price list (exam, cleaning, fillings, crowns, implants); own panoramic/intraoral X-ray equipment with a 3D imaging mode; a WhatsApp/Viber number for sending X-rays and getting a remote treatment plan; branch photo gallery; hours to 20:00 on weekdays with Saturday opening. Google reviews show two independent complaints about unexpected charges (billing not fully explained in advance) but no signs of manipulation. Still unverified: TripAdvisor presence; a documented same-day emergency service (the site states only a general professional duty to treat acute cases, and the Google category list does not include emergency dental service).
2026-08-26Recorded sedation / general anaesthesia availability (informational): not documented in public sources. Own blog states the clinic uses exclusively local anaesthesia for dental procedures.
2026-08-26Deepen 2026-08-26: rechecked website (now live/fetchable, previously 403), contacts, operating status (unchanged); added Google rating (4.7/1,116, largest review base in the record on file), a Facebook page and a WhatClinic listing matching the Dondukov branch as external sources; confirmed exclusively-local-anaesthesia (false) with a source; visibility scout 5 queries - appears only for expats; no uncited sources found to triage.
