Change History
| Date | Change |
|---|---|
| 2026-10-05 | Read 14 of the clinic's Google reviews on 2026-10-02: no repeated complaint, no suspicious review pattern. |
| 2026-10-02 | Website structure read on 2026-10-02: business structured data found. |
| 2026-09-30 | Re-read the clinic's website (every page, in Greek and English), its Facebook page (every post of the past year) and its Google listing on 2026-09-30: cleaning, crown, implant, consultation and X-ray prices corrected to not published, as neither channel gives them (the earlier values rested on a directory listing); filling price recorded as not published; published prices now rest on the website's cost range for clear-aligner orthodontics; clear contacts corrected to yes, as the website gives a phone, an e-mail address and a contact form; clinic photos recorded from the Google listing; the summary no longer says prices are published through third-party listings. |
| 2026-09-29 | Corrected 2026-09-29: review recency within 3 months (newest review dated 2026-07-09). |
| 2026-09-10 | Name-verification write-back 2026-09-10: 1 dentist (Ioannis Ziounas) confirmed via the clinic's own biography page and home-page meta description, both in Greek; source added. (A second listed dentist, "Dr. Konstantinos Tzimas", is not named anywhere on the site's home page or biography page, which together read as this solo-practitioner's full personal site -- not touched here, logged as a removal candidate for review.) |
| 2026-08-25 | License verification 2026-08-25 against O.S.A. (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 '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). |
