Change History
| Date | Change |
|---|---|
| 2026-10-02 | Google indexing quality changed from good to partial after a name-and-city web search on 2026-10-02 (own site first listed at position 4 of 10). |
| 2026-10-01 | Presence on other review platforms re-checked: no profile on WhatClinic, Dental Departures or Bookimed, so this criterion is now no. |
| 2026-09-29 | Checked TripAdvisor's own search and the clinic's website for a TripAdvisor profile: none found on either channel. |
| 2026-09-17 | Re-read on 2026-09-17: the clinic's website (its advanced-technology, implants, crowns/veneers and filling pages, its contact page and homepage, in English) and its Google listing. Recorded: named staff photos on the homepage; consistent phone/email; address published with a linked Google Maps place; digital X-ray documented but the site's "3D scanning" is an intraoral optical scanner and 3D printer, not CBCT; a standalone 3D-scan price published but no price for cleaning, fillings, crowns, implants or consultation; the practice documents packages for diplomatic and expatriate clients. Google reviews show owner replies on every readable review, no recurring complaints or suspicious patterns. Still unverified: TripAdvisor presence, WhatsApp contact and documented emergency care. |
| 2026-08-25 | License verification 2026-08-25 against KMPDC registers: clinic facility license found under 'The Periodontist Dental Centre'; all 3 named dentists matched. |
| 2026-08-25 | Re-verification 2026-08-25: confirmed website live, address/phone unchanged, not permanently closed; recorded Google review count increase 291->296 (rating steady 4.9) and pin coordinates. |
| 2026-07-08 | Added Licensing & Credentials (methodology v1.1): clinic licence and dentists/their licence numbers. |
| 2026-07-04 | Initial data collection. |
