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.

Price Transparency

✗ Prices or price ranges published The clinic's own dedicated 'Honoraires' page describes the three reimbursement categories and publishes no price figures or ranges. [s2] 0/3

Reputation & Reviews

17 / 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 — 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 as of 2026-09-24 [massena-dentaire-nice-deepen-7] 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. [gmpb] 2/2
✓ Active Facebook presence Clinic's own Facebook page, matching name and Nice address [massena-dentaire-nice-deepen-19] 1/1
✗ TripAdvisor presence No listing in TripAdvisor's own search or on the clinic's channels [massena-dentaire-nice-deepen-2] [massena-dentaire-nice-deepen-15] 0/0.5
✓ Other review platforms PagesJaunes: page "Cabinet Dentaire Massena" at 13 rue Masséna, edited by the practice itself; no reviews there yet. [massena-dentaire-nice-deepen-20] 0.5/0.5

Change History

DateChange
2026-10-05Read the clinic's PagesJaunes page on 2026-10-05: its content is edited by the practice itself, so the clinic is recorded as present on a review platform (no reviews there yet).
2026-09-29Re-checked on 2026-09-29 whether the clinic has an identifiable Facebook page: a search of Facebook found the clinic's own page, same name and Massena-district Nice address.
2026-09-24Search visibility checked on 2026-09-24 for the one pending Nice query — "Nice dental clinic for expats": not present for "Nice dental clinic for expats".
2026-09-24Re-read on 2026-09-24: the clinic's website (technologies, treatments, team, fees, emergency and appointment pages) and its Google listing. Recorded: the lead dentist's periodontology diplomas, in-house 3D radiography used for implant and periodontal work-ups, a dedicated emergency page and an emergency option on the appointment form, Doctolib booking embedded on each dentist's own page, a WhatsApp chat contact, and detailed condition/procedure explanations across dedicated pages. No orthodontics; no fixed price figures for cleaning, fillings, crowns, implants, consultations or X-rays — the fees page only explains reimbursement categories; no TripAdvisor profile. Google rating 4.8, review count up to 69. Still unverified: Facebook and other review-platform presence, English-speaking service and work with international patients.
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 (previously unknown — the automated 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.
2026-09-07Adversarial verification pass (the verification pass). 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.
2026-09-07Initial research pass. Discovered via web search ('dentiste Nice'). Own site read live. The plain-name Google Maps automated 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.
