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.

Information Transparency
16 / 20
Whether basic facts about the clinic - its team, premises, services, and location - are publicly verifiable.
| ✓ | Has a working website Own site cabinetdentairelumiere.fr live 2026-09-07, real content (team, services, contact). [s1] | 4/4 |
| ✓ | Dentist names listed Site names Dr Marc Berdougo and Dr Roch de Valbray as lead practitioners (per-doctor booking links), plus associates Margot Barbier, Clémentine Denoncin Peyrard, Cassandre Terrier, Jocelyne Mazet, Catherine Mitaty, Maud Caba and Pascal Eymeric. [s1] | 3/3 |
| ? | Dentist specializations listed | 0/2 |
| ✓ | Real clinic photos The lead owner photograph on the place page is the practice's own reception desk under its LUMIÈRE wall lettering, with a member of staff at the counter — its own premises, not stock. [gmpb] | 2/2 |
| ✓ | Service list published Own site meta description: 'implant dentaire, soins des gencives, prothèses'. [s1] | 3/3 |
| ✓ | Clear contact details Phone and address consistent between own site and Google Maps. [s1] [gmp1] | 2/2 |

Reputation & Reviews
15 / 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 headless reading of 2026-09-07. The star histogram — 90 five-star, 3 four-star, 3 three-star, 2 two-star and 14 one-star — sums to 112, matching the 112 in the place-page header exactly, and its weighted mean 4.366 reproduces the published 4.4. The second Google place at the same street address was opened in the same session and settled: it is «Docteur Roch de VALBRAY - CABINET DENTAIRE LUMIERE», filed under the business category «Dental implants periodontist» and carrying 4.8 on 182 reviews, with this practice's address, telephone and website. It is one named practitioner's own profile inside the practice, not a second record of the practice; the practice's own listing, filed as «Dental clinic», is the one this card cites and it carries 4.4 on 112. The higher figure is disclosed here rather than adopted. [gmp1] [gmp1b] [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] | 2/3 |
| ✓ | Review recency The newest review visible is two months old, which proves the within_3_months bucket and no better. Visible dates: 3, 2, 5, 5, 5, 5, 2 and 6 months. 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 4 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 All eight reviews Google surfaces are five-star and none carries criticism, so no theme could be read; the histogram's one- and two-star mass is 16 of 112 ratings, 14.3 %, below the 25 % at which the methodology withholds the finding. 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. Ordinary distribution for a 112-review practice: 90 five-star with a real tail of 14 one-star and single figures at four, three and two. Reviewers name five different clinicians, wording and length differ and the dates run from two months to six. [gmpb] | 2/2 |

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 (90/3/3/2/14 = 112, weighted mean 4.366), 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). Google place data re-read live under two independent query forms — rating 4.4 and geo reproduced exactly. ONCD re-searched: Dr Roch de Valbray IS on the register under the compound surname CORMAILLE DE VALBRAY (RPPS 10003531307, exact clinic address), so the research pass's licenseNotFound was a false negative and has been withdrawn; six further associates matched at the exact clinic address and one (Dr Maud Caba) at a different registry address, all disclosed. Three aiVisibility fields raised to true under the wave-5 name-in-result rule. A second Google place at the same address (the Dr de Valbray practitioner listing, 4.8/182) is recorded in the rating note and deliberately not used. |
| 2026-09-07 | Initial research pass. Discovered via SearXNG ('dentiste Lyon'). Own site read live, Google Maps headless probe resolved a real POI match (rating, address, geo), ONCD annuaire confirmed Dr Berdougo's RPPS at the exact clinic address; Dr de Valbray searched under two name variants and not found in the register (licenseNotFound, no penalty). Five canonical aiVisibility queries filled from the wave-5 AV pass (scratch/wave5/aivis/france.json); emergency and expats are null because the Lyon SERP is dominated by the South Lyon, Michigan namesake (per wave-5 rule, not a false). |
