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.

Reputation & Reviews

18.5 / 20

Public review signals. The Google rating is adjusted with a Bayesian prior (rating 4.0, weight 25) so a 5.0 from a handful of reviews does not outrank a 4.8 from hundreds.

✓ Google rating (Bayesian-adjusted) Read live on the place page in a browser on 2026-09-08. Unchanged from the automated reading of 2026-09-07. The star histogram — 217 five-star, 2 four-star, 0 three-star, 0 two-star and 8 one-star — sums to 227, matching the 227 in the place-page header exactly, and its weighted mean 4.850 reproduces the published 4.9. [gmp3] [gmpb] 6/6
◐ Google review volume Read live on 2026-09-08 from the place-page header, and the star histogram sums to the same figure. The card held 227 from 2026-09-07 and the listing has not moved since. [gmp3b] [gmpb] 2.5/3
✓ Review recency The newest review visible is two months old, which proves the within_3_months bucket and no better. Visible dates: 2 months, 2 months (edited), 9 and 11 months, then 1, 1, 2 and 2 years. Sample: the eight reviews Google Maps renders on the place page in its own relevance order — the "Newest" sort does not open to automation, so a review more recent than the newest one visible may exist. [gmpb] 3/3
✓ Clinic responds to reviews The owner answers 7 of 8 of the reviews visible on the place page on 2026-09-08. Sample: the eight reviews Google Maps renders on the place page in its own relevance order — the "Newest" sort does not open to automation, so a review more recent than the newest one visible may exist. [gmpb] 2/2
✓ No recurring complaints No criticism appears in the visible sample; the one- and two-star mass is 8 of 227 ratings, 3.5 %. Sample: the eight reviews Google Maps renders on the place page in its own relevance order — the "Newest" sort does not open to automation, so a review more recent than the newest one visible may exist. [gmpb] 2/2
✓ No suspicious review patterns Judged on the histogram shape, the spread of dates, the variety of reviewers and the wording, on 2026-09-08. 217 five-star with a small genuine tail of eight one-star and two four-star ratings; reviews run from two months to two years in two languages, and the owner answers seven of the eight visible. [gmpb] 2/2
✓ Active Facebook presence Site links to the clinic's Facebook and Instagram pages [studio-dentaire-touati-lyon-deepen-2] 1/1
✗ TripAdvisor presence No listing in TripAdvisor's own search or on the clinic's channels [studio-dentaire-touati-lyon-deepen-3] [studio-dentaire-touati-lyon-deepen-4] 0/0.5

Communication & Service

5 / 10

How easy it is to contact the clinic, get answers, and book - especially for international patients.

Change History

DateChange
2026-10-05Read the clinic's PagesJaunes listing on 2026-10-05: the practice has not edited it and it has no reviews, and no other review platform lists the clinic, so it is recorded as not present on other platforms.
2026-09-24Search visibility checked on 2026-09-24 for the two pending Lyon queries — "emergency dentist Lyon" and "Lyon dental clinic for expats": present for "emergency dentist Lyon" and "Lyon dental clinic for expats".
2026-09-24Re-read on 2026-09-24: the clinic's website (team, practice, treatment, price and contact pages, in French and English) and its Google listing. Recorded: dentists' individual implantology/periodontology diplomas, genuine premises photos and video, a Facebook/Instagram presence, an in-house radiography room and 3D jaw imaging before bone grafts, guided implant surgery, and an online periodontitis self-assessment test. No pediatric dentistry, no emergency service (the practice presents itself as offering continuity of care rather than emergency treatment), no WhatsApp/LINE, no TripAdvisor profile. Google rating and review count unchanged at 4.9 from 227 reviews. Still unverified: work with international patients beyond the English-language site, and other review platforms.
2026-09-08Checked by hand in a browser: the clinic’s Google Maps place page was opened in a real browser and read on both its Reviews and Overview tabs. Recorded from it: the rating re-verified against the star histogram, the review count, the histogram itself (217/2/0/0/8 = 227, weighted mean 4.850), review recency, the owner-reply state, the complaint reading and the manipulation reading from the eight most-relevant reviews, the lead owner photograph and the full published opening week. Fields this pass did not measure are untouched.
2026-09-07Adversarial verification pass (the verification pass). Google place re-read live by phone query: rating 4.9 confirmed and the review count (227) recovered, which the research pass had reported as not exposed. The clinic's own team page and price list were read for the first time: a third dentist (Dr Thibault Nicollet) is published by the clinic and matched in ONCD at the exact address, Dr Romane Touati Chebance's RPPS was matched, and seven price fields were resolved from the clinic's published tariff.
2026-09-07Initial research pass. Surfaced directly by the AI-visibility pass (appears in both 'best dentist Lyon France' and 'dental implants Lyon France'). Own English-language site read live. The plain-name Google Maps automated query returned only a city-centroid fallback (no POI); retried successfully with the site's own phone number, which resolved the exact business (rating 4.9, address). ONCD confirmed Dr Touati's RPPS at the exact address.
