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 |
|---|---|
| 2026-10-02 | Read the clinic's Google listing on 2026-10-02 in 3 review orders (15 distinct reviews, dated 2024-04-08 to 2026-09-29; 5.0 from 786): owner replies true; suspicious review patterns false. |
| 2026-10-01 | Presence on other review platforms re-checked: no profile on Doctoralia, WhatClinic or Dental Departures, so this criterion is now no. |
| 2026-09-30 | Looked for the clinic on Facebook under its name and city: no page exists (the site and Google listing link none either). Recorded: not present on Facebook. |
| 2026-09-25 | Search visibility checked on 2026-09-25 for the five standard Rio de Janeiro, Brazil queries: not present for "best dentist Rio de Janeiro, Brazil", "English speaking dentist Rio de Janeiro, Brazil", "dental implants Rio de Janeiro, Brazil", "emergency dentist Rio de Janeiro, Brazil", "Rio de Janeiro, Brazil dental clinic for expats". |
| 2026-09-25 | Found and read on 2026-09-25 the clinic's website, https://rioodonto.com.br/ (name, address and the technical-director credential Dra. Ruth Elen Tavares, CRO-RJ 46533, match the clinic), plus its Google listing (newest and lowest-rated reviews). Corrected: the clinic has a website (previously recorded as having none). The site is a dental-implant landing page: implant surgery is described; hours match the Google listing (Saturday morning included); no structured data and no separate service pages. No recurring complaint theme among the reviews. Still unverified: owner replies to reviews, on-site X-ray/CBCT equipment (the page mentions imaging exams without naming the equipment), services beyond implants, and Facebook presence. |
| 2026-08-25 | License verification 2026-08-25: CNES estabelecimentos registry unreachable (HTTP 503/connection-refused) and CFO/CRO-RJ are captcha-gated - no registry lookup possible for the clinic; doctor Dra. Ruth Elen Tavares already had a recorded CRO-RJ number so was not re-checked. clinicLicense recorded as null with note. |
| 2026-08-25 | Re-verification 2026-08-25: no website on file to check (unchanged; still none listed on Google Maps either). Confirmed address and phone unchanged via Google Maps; clinic open. Recorded Google rating 5.0 (755 reviews), reviewRecency within_3_months, and Maps place URL/coordinates. |
