Change History
| Date | Change |
|---|---|
| 2026-10-02 | Read the clinic's website HTML on 2026-10-02: structured data: present, service pages: present. |
| 2026-10-01 | Presence on other review platforms re-checked on 2026-10-01: Doctoralia has a profile of Dra. Mónica Thirian that lists this clinic at Calle Peñaflor 1, so it is now recorded as present (it was recorded as absent without a platform read). |
| 2026-09-29 | Corrected 2026-09-29: active Facebook presence now unverified: no Facebook search is on record, so the absence of a page is not established. |
| 2026-08-26 | Link-rot + review-list re-check 2026-08-26 (round 2): s1 (www.institutodentalmthirian.com/en/) re-confirmed dead (HTTP 404) — same URL also flagged for review for contacts.website. Re-fetched the bare domain https://institutodentalmthirian.com/ and it is live with matching content (same clinic, same address/phone/services/hours). Re-cited all 18 criteria facts that depended on s1 to the working URL and updated contacts.website to match. licensing.doctors[0] also cites s1 alongside a live sibling (instituto-dental-mthirian-sevilla-doclic) so that citation is unaffected; s1 itself cannot be pruned because licensing.doctors sourceIds are merge-only in the delta-v1 schema (no removal path), so the old dead entry stays in sources[] indefinitely even though every fact now also has a working citation. |
| 2026-08-26 | Link-rot cleanup 2026-08-26: pruning 1 dead source(s) confirmed unreachable in an external-link check (checked 2026-08-26) and re-confirmed dead by direct recheck where applicable. s1 [https://www.institutodentalmthirian.com/en/]: https://www.institutodentalmthirian.com/en/ (HTTP 404, rotten) |
| 2026-08-26 | License verification 2026-08-26: Dr. Mónica Thirian's colegiado number found via GuiaDentistas. Clinic authorization not found in REGCESS after 2 variants; combined with the website already lacking a published number, clinicLicense verified false. |
| 2026-08-25 | Re-verification 2026-08-25: website's /en/ page now 404s (root domain still live with matching address); Google Maps profile lists landline +34 954 33 10 35, not shown anywhere on the site (which only lists the mobile +34 614 113 489 on file) — recorded as observed discrepancy. Newly captured Google rating 5.0 (46 reviews), previously unset. |
| 2026-08-25 | Removed manual red flag(s) no_doctor_credentials: they asserted unpublished licensing while the underlying data was unverified (null means "not checked", not "not published"). See methodology v1.3.0. |
| 2026-08-23 | Recorded sedation / general anaesthesia availability (informational): not documented in public sources. Only local anaesthesia documented; no general anaesthesia or deep sedation mentioned publicly. |
| 2026-08-18 | Imported from the city-tier dataset. |
