Licensing & Credentials

|---|---|
| 2026-09-29 | Corrected 2026-09-29: review recency within 3 months (newest review dated 2026-09-21). |
| 2026-09-24 | Search visibility checked on 2026-09-24 for the five pending Lisbon queries — "best dentist Lisbon", "English speaking dentist Lisbon", "dental implants Lisbon", "emergency dentist Lisbon" and "Lisbon dental clinic for expats": not present for "best dentist Lisbon", "English speaking dentist Lisbon", "dental implants Lisbon", "emergency dentist Lisbon" and "Lisbon dental clinic for expats". |
| 2026-09-24 | Re-read on 2026-09-24: the clinic's website (implants page, promotions page, booking page, full site sitemap) and its Google listing. Recorded: no English version; no filling, crown, implant or x-ray price found; WhatsApp available; online booking form; detailed implant-procedure explanation; emergency service documented via the Google profile's own category; no structured business data. Google listing: owner replies to every recent low review; three reviews describe long waits past the scheduled time; no signs of manipulated reviews. Not found on TripAdvisor. |
| 2026-09-10 | Twin parity 2026-09-10 (clinicLicense): both cards cite the same ERS establishment detail page and both read it on 2026-08-25, but this card recorded only the registration number and the "Registado" state while the twin also read the Licenciamentos section — Licença N.º 24119, tipologia "Clínicas ou consultórios dentários", Estado Licenciada. The fuller reading of the same page is now the cell on both cards; this card's own reading stays cited. |
| 2026-09-10 | Twin parity with portugal-dental (same clinic): this card's licence cell held a sentence about the dentist's OMD professional domicile and his ERS Responsável Técnico record, while the twin card held the number the same register publishes for him, Cédula profissional 01666. The cell now carries the identifier, "OMD 01666", in the form both Portuguese city cards use; the domicile and ERS sentence is kept in the row's internal research note and the ERS source stays cited. |
| 2026-08-25 | License verification 2026-08-25: clinic FOUND in ERS with Registo N.º 170768 (Registado), whose Responsável Técnico 'Priesh Ramniklal' matches the clinic's own listed dentist. Of 4 named dentists, 3 confirmed actively registered with OMD (Priesh Ramniklal, Sandra Marx, Valentim Candeias); Leonor Pereira's only OMD match is domiciled in Coimbra and could not be confirmed as the same person. |
| 2026-08-25 | Re-verification 2026-08-25: confirmed website live, address and phone unchanged, not permanently closed; recorded Google rating 4.8 (271 reviews), coordinates, and reviewRecency for the first time. |
