Change History
| Date | Change |
|---|---|
| 2026-08-25 | License verification 2026-08-25 against Ο.Σ.Α. (Dental Association of Attica) dentist register: both named doctors found as registered members (Ziounas confirmed via matching practice address/phone; Tzimas by unique full-name match). No clinic-scope registry exists for Greece, so the clinic entity itself could not be checked. |
| 2026-08-25 | Re-verification 2026-08-25: old site iddentalclinic.gr no longer resolves (DNS failure); clinic moved to iddentalclinic.com (confirmed live, same address/branding). Google Maps listing shows the clinic as 'Временно закрыто' (temporarily closed) as of today, rating 4.8 (290 reviews), and a new phone +30 21 0724 2211 (was unset). Recorded new website, phone, googleMapsUrl, geo, rating, review count; flagged operating status as closed (temporary). |
