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.

Score Breakdown
Every criterion below is scored from public sources. ✓ verified yes · ✗ verified no / not found · ◐ partial · ? unverified (scores 0, not a negative finding).
Information Transparency
Whether basic facts about the clinic - its team, premises, services, and location - are publicly verifiable.
| ✓ | Has a working website Own site live 2026-09-07, extensive content. [s1] | 4/4 |
| ✗ | Dentist names listed The branch page describes the centre and its services at length and names no individual practising dentist; the site has no team/'notre équipe' page for the Lyon Terreaux branch (link inventory of the branch page re-checked in the verification pass — only other branches, 'à propos', 'hygiène et asepsie' and 'politique tarifaire'). [s1] | 0/3 |
| ? | Dentist specializations listed | 0/2 |
| ✓ | Real clinic photos The lead owner photograph is the centre's own glazed street frontage under the arcade on Place des Terreaux — its own premises. [gmpb] | 2/2 |
| ✓ | Service list published Detailed service list published: preventive care, restorative care, prosthetics/implants, periodontal care, orthodontics, cosmetic dentistry, dental radiology (Cone Beam 3D). [s1] | 3/3 |
| ✓ | Clear contact details [s1] [gmp4] | 2/2 |
| ✗ | English website version No hreflang tags and no /en/ path found. [s1] | 0/2 |
| ✓ | Address and map published [s1] [gmp4] | 2/2 |
Price Transparency
Whether patients can estimate costs before visiting. Published price ranges count; exact prices are not required.
| ✗ | Prices or price ranges published The network's own 'Politique tarifaire' page explains the reimbursement framework and states that fees are posted inside each centre; no price list or ranges are published online. [s2] | 0/3 |

Reputation & Reviews
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 headless reading of 2026-09-07. The star histogram — 990 five-star, 127 four-star, 8 three-star, 12 two-star and 158 one-star — sums to 1295, matching the 1295 in the place-page header exactly, and its weighted mean 4.373 reproduces the published 4.4. [gmp4b] [gmpb] | 4/6 |
| ✓ | 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 carried no count before this pass: the headless map method used in phase C returns the rating but never the review count, which is why every French card was queued to the browser worklist. [gmpb] | 3/3 |
| ✓ | Review recency The newest review visible is three months old, which proves the within_3_months bucket and no better. Visible dates: 3 months, 10 months, 10 months, then 1, 1, 1, 2 and 3 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 One readable negative in the visible sample: a one-star describing a telephone call to warn of a ten-minute delay that nobody answered and a receptionist who would not accommodate the arrival. A single account does not establish a repeated theme; the one- and two-star mass is 170 of 1,295, 13.1 %. 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. A large, polarised real-service profile rather than a manipulation signature: 990 five-star, a substantial 127 four-star tail and 158 one-star, dates across three years, individual owner replies.

Change History
| Date | Change |
|---|---|
| 2026-09-08 | Browser pass (phase I): 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 (previously unknown — the headless map method never returns it), the histogram itself (990/127/8/12/158 = 1295, weighted mean 4.373), 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. |
| 2026-09-07 | Adversarial verification pass (D-france). The Google rating the research pass reported as absent is in fact published: 4.4, read live under two independent query forms on the same place id. FINESS record reproduced exactly. The network's own pricing page was read: it publishes no figures, so pricesPublished is a checked false rather than an unchecked null. The absence of a branch team page was re-confirmed from the branch page's own link inventory. |
| 2026-09-07 | Initial research pass. Discovered via SearXNG ('dentiste Lyon'). Own site read live (a "centre de santé" health-centre branch of the Dentylis network, no named dentist published). Google Maps headless probe resolved the exact POI (address/phone/geo) but carried no numeric rating. FINESS live lookup matched this health centre by denomination and exact address — the correct institutional register for a French centre de santé, distinct from ONCD which covers individual practitioners. |
