Change History
| Date | Change |
|---|---|
| 2026-10-02 | Other review platforms corrected to none: the vrisko.gr directory entry is a bare listing with no reviews and no description from the practice, and it has no profile on WhatClinic, Doctoranytime, Bookimed or Dental Departures (checked 2026-10-02). |
| 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. |
| 2026-09-17 | Re-read on 2026-09-17: the clinic's bilingual website (Thessaloniki branch team page, both contact pages) and its Google listing. Recorded: a named pediatric dentist on the Thessaloniki branch team; no WhatsApp/LINE on either contact page; a genuine Google-listing photo of the reception area; no structured data of a qualifying type despite dedicated specialty pages; Google 4.8 from 220 reviews (up from 213), no recurring-complaint or manipulation pattern in the histogram. Still unverified: X-ray/CBCT, emergency care, pre-visit consultation -- and other review platforms. |
| 2026-09-10 | Name-verification write-back 2026-09-10: 2 dentists confirmed via the clinic's own Thessaloniki-branch team roster page (https://thedentalclinic.gr/iatreio-thesallonikis/, not previously fetched -- the earlier fetch only reached the shared home page); Christina's full surname (Doulkeridou) recovered; sources added. |
| 2026-09-10 | Name-verification write-back 2026-09-10: dentist's full name (Christina Doulkeridou) and specialization confirmed via the clinic's own Thessaloniki-branch team page; source added. |
| 2026-08-27 | Initial data collection for the Greece national index: verified via official website and Google Maps (canonical place URL with geo resolved); O.S.Th. licensing registry checked, no clinic-scope match found. |
