General Anaesthesia & Deep Sedation

Ordinary conscious sedation, where the patient stays awake and responsive, does not count here. This is informational and does not affect the transparency score.

Change History
| Date | Change |
|---|---|
| 2026-10-01 | Other review platforms re-checked on 2026-10-01: Dentistas.net.br page at the clinic's address and phone, with 5 reviews; DentMap and SmileJet, which only repeat Google reviews, are no longer cited for this; the datum previously rested on directory pages. |
| 2026-09-30 | Re-read the clinic's website (in full), its Google listing, its Facebook page and its newest Instagram posts on 2026-09-30: English website version recorded as absent, as the site is in Portuguese only, and prices recorded as not published on any of these channels; the service list, contacts and address now rest on the clinic's website and Google listing. |
| 2026-09-29 | Read the structured data on the clinic's homepage: it includes an Organization entity for the clinic (name, logo, description, email and phone). Recorded: structured data present. |
| 2026-09-17 | Re-read on 2026-09-17: the clinic's site as text, because the live site did not answer a direct read ('O Instituto' team and technology page and 11 dedicated treatment pages), and its Google listing (5 most-relevant reviews). Recorded: named dentists with CRO numbers and specializations, digital X-ray and 3D tomography in-house, weekday hours to 19:00, WhatsApp booking, clear procedure explanations, a Facebook link, a genuine building photo, and no manipulation signs. Still unverified: published prices, an English version, work with foreign patients, English-speaking staff, and TripAdvisor presence. |
| 2026-08-26 | Re-verification 2026-08-26: the website itself blocked automated fetches with HTTP 403 (as it did in a prior session) so name/address/phone could not be independently re-read from the site's own page — not claimed as confirmed via website. However the matching Google Maps listing confirms address and phone unchanged and is open. Rating up from stored 4.9 to 5.0; review count up from 540 to 632. Captured Maps place URL and pin coordinates. |
| 2026-08-25 | Re-verification 2026-08-25: the site is live (domain resolves and responds) but blocked automated fetches with HTTP 403 on both the homepage and a contact subpage, so name/address/phone could not be independently re-read from an opened page — left unchanged rather than claiming confirmation. No Google Maps link could be captured. Google Maps itself also did not return readable content. |
| 2026-08-25 | License verification 2026-08-25 against CNES: no plausible match under 2 name variants, but the clinic's own site remains inaccessible (HTTP 403) so the false-bar's own-site check could not be completed; clinicLicense left null. |
