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.

Change History
| Date | Change |
|---|---|
| 2026-10-01 | Other review platforms re-checked on 2026-10-01: profiles on SuperDoc (33 ratings), Trustpilot (10 reviews) and WhatClinic (6), as on the Sofia site; the datum previously rested only on the clinic's own site. |
| 2026-09-17 | Aligned with the clinic's entry on sofiadentalrating.com: recorded No recurring complaints (yes) from sources read on 2026-08-26. |
| 2026-09-17 | Re-read on 2026-09-17: the clinic's website is now directly reachable (previously not directly fetchable) — its X-ray diagnostics, team, contacts, services, crown and implant/surgery pages in English, plus its Google listing. Recorded: no prices published anywhere despite an extensive site; own digital segmental/panoramic X-ray equipment, no CBCT; children's orthodontic treatment offered; no WhatsApp; an online booking form with file upload; hours to 20:00 on weekdays; Organization structured data; own-hosted team photos. Google reviews are recent, individually answered even when critical, and show no signs of manipulation. Still unverified: TripAdvisor presence; a documented same-day emergency service (not a Google Business Profile category and only incidental 'emergency' wording in unrelated blog posts). |
| 2026-09-10 | Name-verification pass 2026-09-10 (browser): 'Dr. Karteva' appears neither on the clinic’s own exhaustive fourteen-person team page (impressiondent.com/ekip/, read 2026-09-10) nor in the BZS national register under the Cyrillic spelling of Karteva at all (surname searches for Karteva and Kartev in that spelling both return 0 in a real browser, with a passing positive control Ivanov → 430); the one Sofia dentist whose surname romanises to “Karteva” under the statutory transliteration and whose specialty is endodontics — Dr. Teodora Georgieva Karteva (a different Cyrillic spelling of the surname), LPK 160010843 — is registered at a different practice, Sofia, bul. Tsarigradsko shose № 96, not at 13 Henrik Ibsen St.; removed. |
| 2026-09-10 | Name-verification write-back 2026-09-10: Yana Mohammad-Byaleva confirmed by reading the clinic's own Cyrillic team page; source added. The card's other named doctor (Karteva) does not appear anywhere on this same, fully-read team page (which does list every other staff member down to receptionists) — noted here, not acted on. |
| 2026-08-26 | Re-verification 2026-08-26: confirmed website live, address and phone unchanged; captured Google rating 4.8 (220 reviews, previously unset). |
| 2026-08-25 | Re-verification 2026-08-25: confirmed website live, address and phone unchanged. Captured Google Maps profile link and pin coordinates from the clinic's own site. No Google rating/review count could be independently verified today, so left unset as before. |
| 2026-08-25 | License verification 2026-08-25: LZIBPH clinic registration 220911200751 found, founder-named to Dr. Byalev. Dr. Byalev's own BZS record (LPK 220010841) carries the exact same street address as the clinic, a definitive match. Dr. Yana Mohammad-Byaleva and Dr. Karteva not found under two spelling variants each (Byalev/Mohamad-Byaleva; Karteva/Korteva, in Cyrillic) — left null rather than false given transliteration uncertainty. |
| 2026-08-18 | Imported from the city-tier dataset (data originally collected 2026-07-12). |
