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.
- ? General anaesthesia / deep sedation (sleep dentistry) — Not verified The therapy page mentions sedation once without describing a service; not asserted either way.

Kraus in oral surgery and reconstructive dentistry, Dr Dan Kraus in reconstructive dentistry — with an orthodontist and a dental hygienist alongside.

Every criterion below is scored from public sources. ✓ verified yes · ✗ verified no / not found · ◐ partial · ? unverified (scores 0, not a negative finding).
Information Transparency
20 / 20
Whether basic facts about the clinic - its team, premises, services, and location - are publicly verifiable.
| ✓ | Has a working website Read live 2026-09-07: HTTP 200 with real practice content (therapy overview, expertise CVs, referrals, contact), not a placeholder. [s1] | 4/4 |
| ✓ | Dentist names listed The practice's own expertise page names Dr. med. dent. Dan Kraus, Dr. med. dent. Riccardo D. Kraus, Dr. Michele Calabrò and the dental hygienist Gaia Bacci, each with a dated professional history. [s2] | 3/3 |

[s2] | 2/2 |
| ✓ | Real clinic photos The site serves a set of photographs hosted on its own domain and named for this practice (kraus_hero_1..3, kraus_home_1..3), i.e. commissioned imagery of the practice rather than only stock. [s1] | 2/2 |
| ✓ | Service list published The practice publishes its own therapy page listing what it treats — specialist advice and second opinions, implantology, orthodontics including Invisalign, oral surgery, periodontal and prosthetic treatments. [s3] | 3/3 |
| ✓ | Clear contact details "Via Lucchini 6, 6900 Lugano" with a map link and T +41 (0)91 922 63 22 in the header of every page and on the contact page; the number matches the Google place record. [s4] [m1] [m2] | 2/2 |
| ✓ | English website version Complete EN/DE/IT site; the English tree carries the therapy, expertise and contact pages. [s1] | 2/2 |
| ✓ | Address and map published The contact page publishes the street address with a "Map →" link; it matches the Google place record and the practice address MedReg holds for both principals. [s4] | 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 The therapy and contact pages were read in full and carry no price, range or tariff; the site has no tariff page in its navigation. [s3] [s4] | 0/3 |

Reputation & Reviews
16 / 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 4.9. The star histogram's weighted mean, 4.939, 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: 32 five-star, 0 four-star, 1 three-star, 0 two-star and 0 one-star = 33. [gmpb] | 1/3 |
| ✓ | 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 6 months to 4 years. [gmpb] | 3/3 |
| ✓ | Clinic responds to reviews Browser 2026-09-08, 8 visible reviews, sort "Most relevant": the owner has replied to three of the eight. [gmpb] | 2/2 |
| ✓ | No recurring complaints Browser 2026-09-08: read against a complete distribution — the listing carries no one-star and no two-star rating at all (histogram 32/0/1/0/0), so the negative share is zero per cent and there is no theme to repeat. [gmpb] | 2/2 |
| ✓ | No suspicious review patterns Browser 2026-09-08: histogram 32/0/1/0/0 with a mean of 4.939 against a published 4.9; a three-star rating stands on the listing, dates run from two months to four years, one reviewer describes thirty years as a patient, and the wording varies. No manipulation signature. [gmpb] | 2/2 |
| ✓ | Active Facebook presence The clinic's own Facebook page (with the practice's phone and e-mail) is active: latest post 2026-05-19 (checked 2026-10-02). [studio-dentistico-dr-kraus-lugano-fb] | 1/1 |
| ✗ | TripAdvisor presence No TripAdvisor listing found via its search for "Studio dentistico Dr. Kraus Lugano" and "Kraus Dental"; the clinic's site does not link to TripAdvisor (checked 2026-10-05). [studio-dentistico-dr-kraus-lugano-tripadvisor] [studio-dentistico-dr-kraus-lugano-tripadvisor-2] | 0/0.5 |
| ✗ | Other review platforms No review profile on WhatClinic, Trustpilot or local.ch: local.ch has the clinic only as an entry with ratings switched off, and the other two have no page for it (checked 2026-10-02).

Medical Infrastructure
9.5 / 15

| ✓ | Implantology The therapy page lists implantology and the expertise page records a Master of Advanced Studies in Oral and Implant Surgery for Dr Riccardo D. Kraus. [s2] [s3] | 2/2 |
| ✓ | Orthodontics The practice names Dr Michele Calabrò as orthodontics specialist (lingual orthodontics) and lists orthodontics and Invisalign among its therapies; the Google place record also carries the "Orthodontist" category. [s2] [s3] | 2/2 |
| ✓ | Oral surgery Dr Riccardo D. Kraus is a specialist in oral surgery (SSO/SSOS), a federal postgraduate title confirmed in MedReg; the Google place record carries the "Oral surgeon" category. [s2] | 2/2 |

Communication & Service
5 / 10
How easy it is to contact the clinic, get answers, and book - especially for international patients.
| ✗ | WhatsApp / LINE available The footer renders a WhatsApp social icon, but the anchor carries no href at all in the delivered HTML, so no WhatsApp contact is actually published. [s1] | 0/2 |
| ? | Response speed No response-time data available in this pass. | 0/1.5 |
| ✓ | English spoken The practice publishes "Multi-language consulting: Italiano, Deutsch, Schweizerdeutsch, English, Français" on its own home page and runs a full English site. [s1] | 2.5/2.5 |
| ✓ | Pre-visit consultation possible Online booking is published in the header, and the practice offers specialist advice and second opinions as a distinct service, including a referral route for other dentists. [s1] [s3] | 1.5/1.5 |
| ✓ | Clear service explanations The therapy page explains each treatment area in plain language with a "More information" route per topic. [s3] | 1/1 |
| ✗ | Convenient opening hours Hours published on the practice's own Google Business record run 8 AM–5:30 PM, with no evening or weekend opening. [gmp1] | 0/1.5 |
AI & Search Visibility
5.5 / 10
Whether the clinic is discoverable when patients search - including via AI assistants. Checked with fixed queries: "best dentist Switzerland", "English speaking dentist Switzerland", "dental implants Switzerland", "emergency dentist Switzerland", "Switzerland dental clinic for expats".

| ✓ | Structured data on website One schema.org JSON-LD block per page carrying WebSite, WebPage, Person, Article and ImageObject types; no LocalBusiness or Dentist entity type is published, so the markup is present but does not describe the business itself. [s1] | 1.5/1.5 |
| ✓ | Google indexing quality A name-and-street search returns the practice's own domain at ranks 1 and 4 of eighteen, with its own Instagram account at rank 2 and directory listings on local.ch and search.ch behind them (web search 2026-09-07). [giq1] | 2/2 |
