General Anaesthesia & Deep Sedation
Whether the clinic documents treatment under general anaesthesia or deep / twilight sedation — "sleep dentistry", where the patient is asleep and unaware (does not feel, see, or hear the procedure). Ordinary conscious sedation, where the patient stays awake and responsive, does not count here. This is informational and does not affect the transparency score.
- ✗ General anaesthesia / deep sedation (sleep dentistry) — No general anaesthesia or deep sedation documented Offers conscious sedation (if necessary) and nitrous sedation only; explicit quote says patient stays awake. [white-clinic-sedation]

Change History
| Date | Change |
|---|---|
| 2026-10-02 | Read the clinic's Google listing on 2026-10-02 (its lowest-rated and newest reviews with the star histogram): the owner replies to reviews; a repeated complaint among the lowest-rated reviews; no sign of manipulated reviews. |
| 2026-10-02 | Read the clinic's own website (homepage, robots.txt, sitemap and service pages) for site structure: business structured data present. |
| 2026-09-10 | Twin parity 2026-09-10 (clinicLicense): this card published the 2026-08-25 "verified false" that the twin card portugal-dental refuted on adversarial spot-check the next day. The negative rested on ERS searches under the clinic's trade name; the clinic's own privacy policy names the legal entity "Lifezest, S.A. (White Clinic)", NIF 509872921, and ERS lists establishment LIFEZEST WHITE under that entity — Registo N.º 116923, Licença N.º 3909, tipologia "Clínicas ou consultórios dentários", estado Licenciada, Responsável Técnico Miguel Stanley Rosa da Silva, at this card's own address with this card's own phone and e-mail. Value, note and both of the twin's sources are copied without new research; the original ERS search stays cited so the name variants that failed remain on record. |
| 2026-08-25 | License verification 2026-08-25 against ERS (clinic) and OMD (dentist): clinic not found in ERS under name + postal-code filter and its own site publishes no licence number -> clinicLicense = false. Founder Dr. Miguel Stanley confirmed as actively registered with OMD, domicile Lisboa/Oeiras, consistent with the clinic's Oeiras-area address. |
| 2026-08-25 | Recorded sedation / general anaesthesia availability (informational): not documented in public sources. Offers conscious sedation (if necessary) and nitrous sedation only; explicit quote says patient stays awake. |
| 2026-08-25 | Re-verification 2026-08-25: confirmed website live, address and phone unchanged, not permanently closed; recorded Google rating 4.8 (349 reviews), coordinates, and reviewRecency for the first time. |
