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) — Not verified site claims '100% painless treatments' but does not specify anaesthesia type; no GA/deep sedation info found

Change History
| Date | Change |
|---|---|
| 2026-10-05 | Read 12 of the clinic's Google reviews on 2026-10-02: no suspicious review pattern. |
| 2026-10-02 | Other review platforms checked on 2026-10-02: the clinic is listed on vrisko.gr with its telephone and an add-review form (no reviews yet), so presence on other review platforms is recorded. |
| 2026-09-29 | Corrected 2026-09-29: review recency within 3 months (newest review dated 2026-08-11). |
| 2026-09-17 | Re-read on 2026-09-17: both of the clinic's websites -- the English implant site and the main practice site linked from its Google listing -- and the listing itself. Recorded: orthodontics for adults and for children and pediatric dentistry as dedicated services on the clinic's main site; a genuine Google-listing photo of the treatment room; evening hours to 21:00 on three weekdays; owner reply to a critical review about veneer shade, with no recurring complaint pattern; a date cluster in the reviews noted but not confirmed as manipulation; freshest exact review date over a year old. Structured data describing the business is published on the main site. Still unverified: Facebook link, other review platforms. |
| 2026-08-25 | License verification 2026-08-25: Dr. Ioanna Klironomou not found in the O.S.A. Attica dentist register, but this Piraeus clinic falls under a separate, unmapped local registry (O.S. Peiraios, the Dental Association of Piraeus), so this is recorded as null, not false. No clinic-scope registry exists to check the clinic itself. |
| 2026-08-25 | Re-verification 2026-08-25: confirmed website live, address and phone unchanged, clinic open. Note: Google Maps also surfaces this clinic under domain klironomou.gr (same clinic/dentist, Dr Ioanna Klironomou); stored klironomoudental.com still resolves and matches. Recorded Google Maps URL/geo and rating 4.8 (155 reviews, newly captured). |
