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.
Summary
Neighbourhood clinic on Kajaanintie in the Kastelli district of Oulu, describing itself as the original local practice and offering general dentistry plus prosthetics, oral surgery and aesthetic treatment for patients of all ages. Three named dentists and four hygienists, a fully itemised price list quoted after Kela reimbursement, free parking and step-free access. Google resolves the older neighbourhood name "Oulun Kruunu" to this same place record, but the clinic never uses that name in its own channels, and the site oulunkruunu.fi belongs to a different Oulu practice whose published roster and district do not match this one.

Score Breakdown
Every criterion below is scored from public sources. ✓ verified yes · ✗ verified no / not found · ◐ partial · ? unverified (scores 0, not a negative finding).
Information Transparency
16 / 20
Whether basic facts about the clinic - its team, premises, services, and location - are publicly verifiable.
| ✓ | Has a working website Opened and read on 2026-09-07: real clinic content with service, staff, price and contact pages. [s1] | 4/4 |
| ✓ | Dentist names listed Three dentists and four hygienists named with short personal introductions; one hygienist is marked as retired and one on parental leave. [s3] | 3/3 |
| ✗ | Dentist specializations listed The staff page gives names, job titles and personal descriptions but no degrees, universities or specialist qualifications for any of the dentists. [s3] | 0/2 |
| ✓ | Real clinic photos The place page carries an owner photo set and its lead image, read in a browser on 2026-09-08, is the practice's own team photograph — five members of staff in the clinic's coloured scrubs, framed above the practice's green rule. Team, so the criterion is met. [gmpb] | 2/2 |
| ✓ | Service list published Eleven described services: check-up, toothache, filling, chipped tooth, gingivitis, root canal treatment, extraction, scaling, ceramic filling, dental fear and whitening, on top of prosthetics, oral surgery and aesthetic dentistry named on the front page. [s2] | 3/3 |
| ✓ | Clear contact details Booking number, e-mail, street address and the company name with its Finnish business ID published; consistent with the Google place record. [s4] | 2/2 |
| ✗ | English website version The site is Finnish only; it declares no language alternates and carries no switcher. [s1] | 0/2 |
| ✓ | Address and map published Street address published on a dedicated contacts page together with arrival, parking and step-free access instructions. [s4] | 2/2 |
Price Transparency
13 / 15
Whether patients can estimate costs before visiting. Published price ranges count; exact prices are not required.
| ✓ | Prices or price ranges published Standing itemised price list across examinations, fillings, anaesthesia, Cerec ceramics, root canal treatment, stomatognathic physiology, oral surgery, radiography and hygienist care, quoted with the Kela reimbursement already deducted and no office fee. [s5] | 3/3 |
| ✓ | Cleaning price listed Parodontologinen hoito including scaling 115 € (20 min), 130 € (30 min), 159 € (45 min). [s5] | 2/2 |
| ✓ | Filling price listed Small filling 52 €, one-surface 84 €, two 149 €, three or more 165 €. [s5] | 2/2 |
| ✓ | Crown price listed Terä tai kruunu 200 €; Cerec ceramic restorations 400–1000 €. [s5] | 2/2 |
| ✗ | Implant price listed No implant price appears in the price list, and implants are not among the named services. [s5] | 0/2 |
| ✓ | Consultation price listed Suun perustutkimus, up to 20 minutes, 49 €; emergency-type visit 51 €. [s5] | 2/2 |
| ✓ | X-ray / imaging price listed Bite-wing 23 €, intraoral 34 €, panoramic (OPTG) 95 €. [s5] | 2/2 |
Reputation & Reviews
13 / 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 — 22 five-star, 0 four-star, 0 three-star, 0 two-star and 1 one-star — sums to 23, matching the 23 in the place-page header exactly, and its weighted mean 4.826 reproduces the published 4.8. The «second brand» question the open question raised is also settled: a Google Maps search for «Oulun Kruunu hammaslääkäriasema Oulu», run in a browser on 2026-09-08, returns this place — Hammaslääkäriasema Kastellin Kruunu, 4.8 on 23, Kajaanintie 79 — as the only Kruunu practice in Oulu. **No separate Oulun Kruunu place record exists**, so there is one practice here and not two, and no second card is due. The clinic's own site calls itself «se aito ja alkuperäinen» — the genuine and original — Oulu dental clinic and never uses the Oulun Kruunu name. [gm1] [gmpb] | 4/6 |
| ◐ | 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 held 23 and the listing has not moved since. [gm1] [gmpb] | 1/3 |
| ✓ | Review recency Newest Google review is dated 2026-08-30 (listing read 2026-09-25). [hammaslaakariasema-kastellin-kruunu-oulu-gbp-2026-09-25] | 3/3 |
| ? | Clinic responds to reviews Only 7 of the 10 Google reviews read are dated within the last 24 months (2024-12-18 to 2026-08-30), fewer than the ten needed to judge whether the owner replies; none carries an owner reply. | 0/2 |
| ✓ | No recurring complaints One critical account is visible, a one-star ten years old about the reception's manner — «customer service is abysmal, blaming customers 10/10 and listening 0/10» — which also alleges that medication-induced gingival hyperplasia went unrecognised. It stands alone in the sample and it is the only one- or two-star rating the listing holds: 1 of 23 = 4.3 %. No theme repeats, so the criterion is false. 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. The distribution is two-valued (22 five-star, 1 one-star, nothing between) but on a base of 23 accumulated over at least ten years that is unremarkable: the visible dates spread from ten months to a decade, the accounts name different clinicians and describe different treatments, and the owner answers none of them at all — the opposite of a curated record. [gmpb] | 2/2 |
| ✓ | Active Facebook presence The clinic links its own Facebook page from its site, alongside Instagram and X. [fb1] | 1/1 |
| ✗ | TripAdvisor presence No TripAdvisor listing found via its search for "Hammaslääkäriasema Kastellin Kruunu Oulu" and "Kastellin Kruunu"; the clinic's site does not link to TripAdvisor (checked 2026-10-05). [hammaslaakariasema-kastellin-kruunu-oulu-tripadvisor] [hammaslaakariasema-kastellin-kruunu-oulu-tripadvisor-2] | 0/0.5 |
| ✗ | Other review platforms No profile on WhatClinic or Trustpilot, its Yelp page is an unclaimed listing with no reviews, and Dental Departures and Bookimed do not cover Finland (checked 2026-10-02). [hammaslaakariasema-kastellin-kruunu-oulu-platforms] [hammaslaakariasema-kastellin-kruunu-oulu-platforms-2] [hammaslaakariasema-kastellin-kruunu-oulu-deepen] [hammaslaakariasema-kastellin-kruunu-oulu-platforms-3] [hammaslaakariasema-kastellin-kruunu-oulu-platforms-4] | 0/0.5 |
Medical Infrastructure
7 / 15
The range of publicly documented equipment and services. This measures documented availability, not clinical quality.
| ✓ | On-site X-ray Bite-wing, intraoral and panoramic imaging priced in the clinic's own price list. [s5] | 2/2 |
| ✗ | CBCT (3D imaging) The price list covers bite-wing, intraoral and panoramic imaging only; no cone-beam CT is priced or described. [s5] | 0/2 |
| ✗ | Implantology The clinic names general dentistry, prosthetics, oral surgery and aesthetic dentistry as its services; implants are not among them and are not priced. [s1] [s2] | 0/2 |
| ✗ | Orthodontics Orthodontics is not named among the services or priced. [s1] [s2] | 0/2 |
| ✓ | Oral surgery Oral surgery is named as a service on the front page, and surgical extraction is priced at 323 €. [s1] [s5] | 2/2 |
| ✓ | Pediatric dentistry The clinic states in its site-wide footer that it provides comprehensive dental services for people of all ages ('kaikenikäisille'). [s1] | 1.5/1.5 |
| ✓ | Emergency care The front page promises an appointment the same or the next day, and the price list carries an emergency-type visit at 51 €. [s1] [s5] | 1.5/1.5 |
| ✗ | Works with international patients The clinic publishes nothing about foreign patients and keeps no non-Finnish version of its site. [s1] | 0/2 |
Communication & Service
2.5 / 10
How easy it is to contact the clinic, get answers, and book - especially for international patients.
| ✗ | WhatsApp / LINE available Phone, SMS to the same number, e-mail and online booking only. [s1] | 0/2 |
| ? | Response speed | 0/1.5 |
| ? | English spoken The clinic makes no statement about the languages it works in, and there is no non-Finnish version to infer from. | 0/2.5 |
| ✓ | Pre-visit consultation possible The check-up page states that a cost estimate is given on request at the examination visit so that the price of treatment is not a surprise. [s2] | 1.5/1.5 |
| ✓ | Clear service explanations Each of the eleven services is explained in plain Finnish, with what causes the problem and what the treatment involves. [s2] | 1/1 |
| ✗ | Convenient opening hours Settled as a checked negative in a browser on 2026-09-08, which is what the open question asked for. The clinic's own contacts page was rendered and read: it carries the company name, the business ID, the street address, the booking number and an e-mail, and **no opening hours of any kind** — no time range appears anywhere in the page's rendered text, so nothing is being hidden behind JavaScript. The clinic's Google Business Profile likewise publishes no hours (the record offers «Add hours»). With no hours published on any channel, a criterion that asks for evening or weekend opening «published clearly» cannot be met, and the value moves from unassessed to a verified false. [gmpb] | 0/1.5 |
AI & Search Visibility
5 / 10
Whether the clinic is discoverable when patients search - including via AI assistants. Checked with fixed queries: "best dentist Finland", "English speaking dentist Finland", "dental implants Finland", "emergency dentist Finland", "Finland dental clinic for expats".
| ✗ | Mentioned for: best dentist Finland The canonical city query was run in the AI-visibility pass on 2026-09-07; the clinic does not appear in the returned result list, which is held by national chains, the city and wellbeing-county pages, Wikipedia and directories. [bsq1] | 0/1 |
| ✗ | Mentioned for: English speaking dentist Finland The canonical city query was run in the AI-visibility pass on 2026-09-07; the clinic does not appear in the returned result list, which is held by national chains, the city and wellbeing-county pages, Wikipedia and directories. [bsq2] | 0/1 |
| ✗ | Mentioned for: dental implants Finland The canonical city query was run in the AI-visibility pass on 2026-09-07; the clinic does not appear in the returned result list, which is held by national chains, the city and wellbeing-county pages, Wikipedia and directories. [bsq3] | 0/1 |
| ✗ | Mentioned for: emergency dentist Finland The canonical city query was run in the AI-visibility pass on 2026-09-07; the clinic does not appear in the returned result list, which is held by national chains, the city and wellbeing-county pages, Wikipedia and directories. [bsq4] | 0/1 |
| ? | Mentioned for: Finland dental clinic for expats The fifth canonical query was not run for this city in the AI-visibility pass: the pass ran it only for the first research city of each country (Helsinki for Finland). Left unset rather than guessed. | 0/1 |
| ✓ | Structured data on website The site's schema.org JSON-LD graph carries a business-level Organization entity for the practice ("Hammaslääkäriasema Kastellin Kruunu Oy") alongside the generic WebPage/WebSite/BreadcrumbList nodes. Re-read on 2026-09-07: that Organization node carries the business name, the site URL and, where present, its social profiles — but no PostalAddress, no telephone and no geo. It is therefore not LocalBusiness or Dentist markup; it is credited under the criterion's "or equivalent" wording as business-level structured data. [s1] | 1.5/1.5 |
| ✓ | Google indexing quality The clinic's own domain holds the first result for its own name and six of the first seven (front page, booking, contacts, dentist landing page, price list, services); the rest are its Instagram profile and directories. [giq1] | 2/2 |
| ✓ | Dedicated service pages Eleven individual service pages, one per treatment or complaint. [s2] | 1.5/1.5 |

Change History
| Date | Change |
|---|---|
| 2026-10-05 | TripAdvisor presence checked on 2026-10-05: no listing found for this clinic. |
| 2026-10-05 | Google reviews re-read on 2026-10-05: 7 from the last 24 months, fewer than the ten needed, so owner replies are left unassessed. |
| 2026-10-02 | Yelp page read on 2026-10-02: an unclaimed listing with no reviews, so no profile on any review platform; presence on other platforms set to no. |
| 2026-10-02 | Read 10 of the clinic's Google reviews on 2026-10-02: no owner replies seen. |
| 2026-10-02 | Presence on review platforms checked on 2026-10-02: no WhatClinic or Trustpilot profile; a Yelp page exists but could not be read, so left unverified. |
| 2026-09-29 | Corrected 2026-09-29: clinic responds to reviews now unverified: only 8 reviews were checked for owner replies; review recency within 3 months (newest review dated 2026-08-30). |
| 2026-09-10 | Name-verification pass 2026-09-10: 3 doctor(s) previously no-match against the own-site roster confirmed by re-reading the clinic's staff/team page(s) (Katja Karimo; Pasi Keränen; Raine Oikarinen); no data other than sources/license-passthrough changed. |
| 2026-09-08 | Checked 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, the histogram itself (22/0/0/0/1 = 23, weighted mean 4.826), 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 | Initial data collection: clinic website read across the front page, service pages, staff page, contacts and price list; Google Maps place record read live. A separate automated place query for the second brand 'Hammaslääkäriasema Oulun Kruunu' resolved to this same place record, so one card was kept and the second name disclosed in the summary rather than a duplicate created. Review-side fields and both licence layers left unset with reasons and queued for a manual browser check. |
