General Anaesthesia & Deep Sedation

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
15.5 / 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 headless reading of 2026-09-07. The star histogram — 63 five-star, 1 four-star, 0 three-star, 0 two-star and 3 one-star — sums to 67, matching the 67 in the place-page header exactly, and its weighted mean 4.806 reproduces the published 4.8. [gmp5] [gmp5b] [gmpb] | 5/6 |
| ◐ | 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] | 1.5/3 |
| ✓ | Review recency The newest review visible is one month old, which proves the within_3_months bucket and no better. Visible dates: 1, 1, 2, 2, 5, 5 and 7 months, and one two years old. 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 1 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 Two readable one-star accounts, on different subjects: one alleges rough handling and impolite conduct by a named clinician during treatment — recorded here as an unproven patient account and without repeating the name — and the other describes onlays after which food lodged constantly between two teeth, a complaint the reviewer says was dismissed as normal and which persists nearly two years later. Different subjects, so no repeated theme; the one- and two-star mass is 3 of 67, 4.5 %. 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. 63 five-star with one four-star and three one-star; the visible reviews run from one month to two years, name different clinicians and vary widely in length.

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 (63/1/0/0/3 = 67, weighted mean 4.806), 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). A fifth dentist the clinic publishes on its own team page (Dr Benoît Brehinier) was missing from the card and has been added; the only national ONCD match on that surname is at a Réunion address, so it is recorded as a namesake and the number is not attributed. Three of the four remaining dentists matched in ONCD, two at the exact clinic address. The clinic's own 'Honoraires' page was read: no figures, so pricesPublished is a checked false. Google rating 4.8 and geo reproduced under an independent query form. |
| 2026-09-07 | Initial research pass. Discovered via SearXNG ('dentiste Nice'). Own site read live. The plain-name Google Maps headless query returned only a city-centroid fallback; retried successfully with the site's own phone number, which resolved the exact business (rating, address, geo). ONCD confirmed Dr Melloul's RPPS at the exact clinic address. |
