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.

Reputation & Reviews
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) Confirmed on the live place page 2026-09-08. Star histogram: 45 five-star, 0 four-star, 0 three-star, 0 two-star, 1 one-star; the buckets sum to 46, exactly the header count, and the weighted mean 4.913 reproduces the published 4.9. [gmpb] | 5/6 |
| ◐ | Google review volume Confirmed against the place-page header 2026-09-08; the star histogram sums to the same figure. [gmpb] | 1/3 |

| ✓ | Clinic responds to reviews Owner replies to reviews on the Google listing: 1 of the 5 newest reviews answered, owner reply dated 2026-09-11 (read 2026-09-26). [tanngarden-trondheim-gbp-2026-09-26] | 2/2 |
| ✓ | No recurring complaints No negative review surfaced in the visible sample and the histogram holds a single one-star: negative mass 1 of 46 = 2.2 per cent. Same relevance-ordered sample. [gmpb] | 2/2 |
| ✓ | No suspicious review patterns Dates spread across more than a year, varied reviewers, no burst. Same relevance-ordered sample. [gmpb] | 2/2 |
| ✓ | Active Facebook presence The clinic’s own site links its Facebook page. [s1] | 1/1 |
| ✗ | TripAdvisor presence No TripAdvisor listing found via its search for "Tanngarden Trondheim" and "Tanngarden dental"; the clinic's site does not link to TripAdvisor. [tanngarden-trondheim-deepen] [tanngarden-trondheim-deepen-2] | 0/0.5 |
| ✓ | Other review platforms Legelisten.no, the Norwegian dentist review site, has a page for the practice at the same address and phone: 5.0 of 5 from 7 patient reviews (newest 5 June 2025). [tanngarden-trondheim-deepen-3] | 0.5/0.5 |
Medical Infrastructure

Change History
| Date | Change |
|---|---|
| 2026-10-02 | Presence on review platforms checked on 2026-10-02: no TripAdvisor listing (its search and the clinic's site read); a Legelisten.no review page found. |
| 2026-09-29 | Corrected 2026-09-29: owner replies to reviews confirmed on the Google listing (owner reply dated 2026-09-11). |
| 2026-09-10 | Name-verification pass 2026-09-10: Nina Sivertsen, Randi Rian Five, Siri Berger confirmed via own-site roster page(s) not read in the original check (or matched under a spelling/transliteration variant). Source(s) added; license value(s) left exactly as on record. |
| 2026-09-08 | Browser reputation pass (I-3): live Google place page opened; rating and count confirmed with the full histogram, recency, owner replies (none), complaint reading and manipulation check recorded. googleMapsUrl replaced with the place URL. |
| 2026-09-07 | Adversarial verification: rating 4.9 re-confirmed independently and a live review count of 46 recorded. The aiVisibility pseudo-source cited a Norwegian query string ("tannlegekontor Trondheim") that the AI-visibility pass never ran — corrected to the canonical query. The clinic's own "Om oss" and "Tannbehandling" pages were opened, giving three named dentists (now in licensing.doctors with honest null licences), a sixty-page treatment catalogue, staff portraits, four further price fields and five infrastructure facts — with verified negatives on cleaning and implant pricing, orthodontics, paediatrics, sedation, CBCT and structured data (the site carries no schema.org markup at all). |
| 2026-09-07 | Initial data collection: own website (price page) and a live Google Maps place lookup. aiVisibility checked against the AI-visibility pass — not found in any of the four Trondheim canonical-query result lists, recorded as false throughout. Reputation beyond rating and licensing left null for the reasons stated on every card in this file. |
