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.

| ✗ | Dentist specializations listed The team block gives each dentist the university they trained at and the languages they speak, but no specialisation or postgraduate title is published against any named dentist. [s1] | 0/2 |
| ✓ | Real clinic photos Self-hosted portraits on the clinic’s own domain named after each team member (Oscar_Svennung.jpg, Lovisa_Langenstam.png, Irena_Vasic.png and so on) plus a team photograph. [s1] | 2/2 |

Price Transparency
0 / 15
Whether patients can estimate costs before visiting. Published price ranges count; exact prices are not required.
| ✗ | Prices or price ranges published Checked the whole navigation of the clinic’s own site, in German and in English: there is no price, price list or cost page and no figure on the treatment or emergency pages. [s1] | 0/3 |

Reputation & Reviews
18 / 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) Re-read live on the place page in a browser on 2026-09-08 and unchanged at 4.6. The star histogram's weighted mean, 4.643, reproduces the published figure. [gmp1] [gmpb] | 5/6 |
| ◐ | Google review volume Headline count read on the place page in a browser on 2026-09-08. The histogram sums to the same figure: 329 five-star, 9 four-star, 4 three-star, 4 two-star and 26 one-star = 372. [gmpb] | 2.5/3 |
| ✓ | Review recency Browser 2026-09-08, 8 visible reviews, sort: Google's own "Most relevant" order. The newest visible review is two months old; the rest run 7 to 8 months, 1 year and 2 years. [gmpb] | 3/3 |
| ✓ | Clinic responds to reviews Browser 2026-09-08, 8 visible reviews, sort "Most relevant": the owner has replied to all eight, including the critical one. [gmpb] | 2/2 |
| ✓ | No recurring complaints Browser 2026-09-08, 8 visible reviews, sort "Most relevant": one readable negative account, about the practice charging the full treatment fee for a missed appointment under a 24-hour cancellation policy, answered by the owner. A single instance is not a repeated theme. One-star and two-star ratings together are 30 of 372, or 8.1 per cent of the base. [gmpb] | 2/2 |
| ✓ | No suspicious review patterns Browser 2026-09-08: histogram 329/9/4/4/26 with a mean of 4.643 against a published 4.6 — a polarised but ordinary service profile with a substantial one-star tail, dates spread across years and varied wording. No manipulation signature. [gmpb] | 2/2 |
| ✓ | Active Facebook presence The clinic links its own Facebook page facebook.com/ZahnCity from its site. [s1] | 1/1 |
| ✗ | TripAdvisor presence No TripAdvisor listing found via its search for "ZahnCity Zurich" and "ZahnCity Zahnarzt"; the clinic's site does not link to TripAdvisor (checked 2026-10-05). [zahncity-zurich-tripadvisor] [zahncity-zurich-tripadvisor-2] | 0/0.5 |
| ✓ | Other review platforms Has its own clinic profile on WhatClinic (1 verified patient review, 4.0). [zahncity-zurich-platforms] | 0.5/0.5 |
