Anesthésie générale & sédation profonde
Indique si la clinique documente des soins sous anesthésie générale ou sédation profonde / crépusculaire — la « dentisterie sous sommeil », où le patient dort et n'a conscience de rien (il ne sent, ne voit et n'entend pas l'intervention). La sédation consciente ordinaire, où le patient reste éveillé et réactif, ne compte pas ici. Information indicative, sans effet sur le score de transparence.

Transparence de l'information
20 / 20
Indique si les faits de base concernant la clinique — son équipe, ses locaux, ses services et sa localisation — sont vérifiables publiquement.
| ✓ | Dispose d'un site web fonctionnel https://www.densartis.ch/ returned HTTP 200 with 4,831 characters of the practice’s own content — services, team, practice, contact, opening hours — read on 2026-09-07. [s1] | 4/4 |
| ✓ | Noms des dentistes publiés The team page names Dr. med. dent. Thomas Gasser as owner and dentist and med. dent. Julia Ledergerber as dentist, next to the named practice manager, hygienist and assistants. [s2] | 3/3 |
| ✓ | Spécialisations des dentistes indiquées The site footer publishes the owner’s titles against his name — specialist dentist for reconstructive dentistry (SSRD), MAS in oral implantology from the University of Zurich, member of SSO, ITI, EPA and SGDMFR — and the practice keeps a specialisation page of its own. [s1] [s2] | 2/2 |
| ✓ | Photos réelles de la clinique Settled in a browser on 2026-09-08 from the practice's own Google Business Profile: the lead owner photograph shows one of this practice's own treatment rooms, with the chair, unit and cabinetry in the daylit corner room at Greifengasse 1. [gmpb] | 2/2 |
| ✓ | Liste des services publiée The navigation publishes a services section with separate pages for reconstructive dentistry, prostheses and veneers, plus a before-and-after gallery of its own cases. [s1] | 3/3 |
| ✓ | Coordonnées claires Address Greifengasse 1, 4058 Basel, telephone +41 61 681 00 10, the practice e-mail address on the SSO secure-mail domain and the weekday opening hours are published on the site. [s1] | 2/2 |
| ✓ | Version anglaise du site web The practice publishes an English page for international patients, "English Speaking Dentist Basel – Dental Care for Expats", at its own /en/ route. [s3] | 2/2 |
| ✓ | Adresse et carte publiées The site publishes the postal address in its footer together with the opening hours and links its location. [s1] | 2/2 |
Transparence des prix
0 / 15
Indique si les patients peuvent estimer les coûts avant leur visite. Les fourchettes de prix publiées comptent ; des prix exacts ne sont pas exigés.
| ✗ | Prix ou fourchettes de prix publiés Checked the practice’s own navigation, the international-patients page and the footer link labelled Tariffe: the link resolves to the site’s 404 page, and no price, price list, tariff point value or range is published anywhere else on the site. [s1] [s3] | 0/3 |
| ✗ | Prix du détartrage indiqué [s1] | 0/2 |
| ✗ | Prix des obturations indiqué [s1] | 0/2 |

Réputation et avis
15 / 20
Signaux d'avis publics. La note Google est ajustée avec un a priori bayésien (note 4,0, poids 25) afin qu'un 5,0 issu d'une poignée d'avis ne surclasse pas un 4,8 issu de centaines d'avis.
| ◐ | Note Google (ajustement bayésien) Re-read live on the place page in a browser on 2026-09-08 and unchanged at 4.8. The star histogram's weighted mean, 4.810, reproduces the published figure. [gmp1] [gmpb] | 4/6 |
| ◐ | Volume d'avis Google Headline count read on the place page in a browser on 2026-09-08. The histogram sums to the same figure: 20 five-star, 0 four-star, 0 three-star, 0 two-star and 1 one-star = 21. [gmpb] | 1/3 |
| ✓ | Fraîcheur des avis Newest Google review is dated 2026-08-21 (listing read 2026-09-29). [dens-artis-dr-gasser-basel-gbp-2026-09-29] | 3/3 |
| ✓ | La clinique répond aux avis Browser 2026-09-08, 8 visible reviews, sort "Most relevant": the owner has replied individually to all eight. [gmpb] | 2/2 |
| ✓ | Absence de plaintes récurrentes Browser 2026-09-08, 8 visible reviews, sort "Most relevant": no review below five stars surfaced and no repeated theme is readable. The single one-star rating on the listing is 1 of 21, so one-star and two-star ratings together are 4.8 per cent of the base. [gmpb] | 2/2 |
| ✓ | Absence de schémas d'avis suspects Browser 2026-09-08: histogram 20/0/0/0/1 with a mean of 4.810 against a published 4.8. Two facts are disclosed rather than scored — six of the eight visible reviews were written inside a three-month window (five to seven months ago), and several reviewers identify themselves as fellow dentists or dental technicians, which is ordinary for a referral specialist practice. Against manipulation: a genuine one-star rating stands on the listing, the accounts describe different procedures and colleagues, and the owner answers each individually. [gmpb] | 2/2 |
| ✓ | Présence Facebook active The clinic's own Facebook page (Greifengasse 1, with the practice's phone, e-mail and website) is active: latest post 2026-09-11 (checked 2026-10-02). [dens-artis-dr-gasser-basel-fb] | 1/1 |
| ✗ | Présence sur TripAdvisor No TripAdvisor listing found via its search for "Dens Artis Basel" and "Dens Artis"; the clinic's site does not link to TripAdvisor (checked 2026-10-05). [dens-artis-dr-gasser-basel-tripadvisor] [dens-artis-dr-gasser-basel-tripadvisor-2] | 0/0.5 |
| ✗ | Autres plateformes d'avis No review profile found on WhatClinic, Trustpilot or local.ch, where ratings are switched off for its entry (checked 2026-10-01). [dens-artis-dr-gasser-basel-platforms] [dens-artis-dr-gasser-basel-platforms-2] [dens-artis-dr-gasser-basel-platforms-3] | 0/0.5 |

| ✓ | Implantologie The practice publishes implants as one of its declared fields and its owner holds an MAS in oral implantology; "Dental implants provider" and "Dental implants periodontist" are categories on its own Google Business Profile. [s1] [gmp1] | 2/2 |

Communication et service
3.5 / 10
La facilité avec laquelle on peut contacter la clinique, obtenir des réponses et prendre rendez-vous — en particulier pour les personnes ne parlant pas la langue locale.
| ✗ | WhatsApp / LINE disponible No WhatsApp, Line or comparable messaging channel is published on the practice’s own site; contact runs through the telephone, the e-mail address and online booking. [s1] | 0/2 |
| ? | Rapidité de réponse | 0/1.5 |
| ✓ | Anglais parlé The practice publishes an English page describing itself as an English-speaking dentist in Basel. [s3] | 2.5/2.5 |
| ✗ | Consultation préalable possible Read on 2026-09-09 after the page did not load on 2026-09-08; the site is plain server-rendered Wix content. The English-speaking-dentist page invites patients "seeking a second opinion" to "discuss your individual situation" — a general consultation invitation, not an offer to draw up a written cost estimate (contrast the UZB Basel precedent, which names a dedicated Kostenvoranschlag section). No page on the site offers one. [s3] | 0/1.5 |
| ✓ | Explications claires des services Each field has its own page, the practice keeps a before-and-after gallery explaining its own cases and the international-patients page explains the process in English. [s1] [s3] | 1/1 |
| ✗ | Horaires d'ouverture pratiques Published hours are Monday to Friday, from 08:00 or 09:00 to 17:00 or 18:00, with no evening or weekend surgery. [s1] | 0/1.5 |

Historique des modifications
| Date | Modification |
|---|---|
| 2026-10-05 | TripAdvisor presence checked on 2026-10-05: no listing found for this clinic. |
| 2026-10-02 | Facebook presence checked on 2026-10-02: the clinic's own page is active (latest post 2026-09-11). |
| 2026-10-01 | Review platforms re-checked: no profile of the clinic on WhatClinic, Trustpilot or local.ch, so "reviewed on other platforms" changed from yes to no. |
| 2026-09-29 | Corrected 2026-09-29: active Facebook presence now unverified: no Facebook search is on record, so the absence of a page is not established; review recency within 3 months (newest review dated 2026-08-21). |
| 2026-09-08 | Checked by hand in a browser: review count, histogram, recency, owner-reply state, complaint and manipulation readings recorded; practice photographs settled from the profile's own lead image; the listing confirmed to carry both densartis.ch and zahnarztgasser.ch alongside the card's address and telephone, so the second domain belongs to this practice. |
| 2026-09-07 | Initial data collection: clinic site read body-first across home, team and English pages, and the footer Tariffe link followed to its 404 page, which established the absence of any published price; Google Maps place record read live for rating, coordinates, address, phone and business categories, and the second domain in the listing recorded; MedReg queried for both named dentists and the full licence records read, both at the card address; BetReg queried for Basel and by name with no entry found; the four canonical visibility queries taken from the AI-visibility pre-pass; indexing quality measured with a name search. |
