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) — No general anaesthesia or deep sedation documented Offers oral/inhalation/moderate IV sedation only; deepest state described is patient 'lightly asleep' but monitored, no general anesthesia. [seoul-one-top-365-sedation]

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
Whether basic facts about the clinic - its team, premises, services, and location - are publicly verifiable.
Price Transparency
Whether patients can estimate costs before visiting. Published price ranges count; exact prices are not required.
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) Star histogram read live on 2026-09-06 from the place page: 76 five-star, 4 four-star, 0 three-star, 0 two-star, 1 one-star. The buckets sum to 81, matching the 81 in the place-page header exactly, and the weighted mean 4.901 reproduces the published 4.9. [gmp1] | 6/6 |

| ✓ | No recurring complaints Low ratings are few (1★ 1 / 2★ 0 / 3★ 0 / 4★ 4 / 5★ 88; 1.1 % one or two stars) and too scattered to share a theme. [seoul-one-top-365-deepen] | 2/2 |
| ✓ | No suspicious review patterns 10 Google reviews read (2026-01-05 to 2026-09-29): no burst of five-star ratings (at most 2 on one day), no repeated wording; accounts hold 1-7 reviews, 5 single-review. [seoul-one-top-365-deepen] | 2/2 |
| ✓ | Active Facebook presence Facebook page "Seoul OneTop Dental Clinic" (17 followers) with posts up to 2026-10-02, found under the clinic's name; its About section gives the clinic's Gangseo-ro address. [seoul-one-top-365-presence] | 1/1 |

Change History
| Date | Change |
|---|---|
| 2026-10-05 | TripAdvisor presence checked on 2026-10-05: no listing found for this clinic. |
| 2026-10-02 | Read 10 of the clinic's Google reviews on 2026-10-02: the owner replies to reviews, no repeated complaint, no suspicious review pattern. |
| 2026-10-02 | Facebook presence re-checked on 2026-10-02: live Facebook page confirmed. |
| 2026-10-02 | Website structure read on 2026-10-02: no business structured data found. |
| 2026-09-29 | Corrected 2026-09-29: clinic responds to reviews now unverified: only 3 reviews were checked for owner replies; review count 91 (was 81) from the Google listing on 2026-09-26. |
| 2026-09-07 | opaque_prices flag removed under methodology v1.4.0 (no evidence of bait/opacity; non-publication is scored by price criteria). |
| 2026-09-07 | Reputation block written from the live measurement taken on 2026-09-06, which read this clinic’s Google Maps place page but could not write to it: the twin carries no entry in data/research/*.json, so import-research.js left it untouched and the figures stayed in the trail (browser/korea-japan.md, «Open for the gate» item 2). Written now: googleRating 4.9 → 4.9, googleReviewCount 75 → 81 (histogram 76/4/0/0/1 = 81, weighted mean 4.901), respondsToReviews → false. The trail did not measure reviewRecency, recurringComplaints, suspiciousReviewPatterns for this clinic, so those fields are left exactly as it stood. The country twin on korea-dental was re-synchronised from this card in the same step; the two copies are identical except for the twin’s city key. |
| 2026-08-26 | License verification 2026-08-26 against HIRA (Health Insurance Review and Assessment Service): clinic confirmed as registered 365 Seoul Wontap Chigwa-uiwon at the address on file. No public name-searchable dentist licence register exists in South Korea (lic.mohw.go.kr is document/barcode verification only) — the named doctor left null with that note. |
| 2026-08-26 | Re-verification 2026-08-26: confirmed website live, name/address/phone unchanged, clinic open. Newly captured Google Maps rating 4.9 (75 reviews, most recent review ~1 month old) with pin coordinates via live Maps visit. |
| 2026-08-25 | Recorded sedation / general anaesthesia availability (informational): not documented in public sources. Offers oral/inhalation/moderate IV sedation only; deepest state described is patient 'lightly asleep' but monitored, no general anesthesia. |
| 2026-08-25 | Re-verified live facts (website, contacts, operating status): no changes. Google reputation not captured — no search route to Google/Maps/Bing/DuckDuckGo/Yandex was available on the date of reading. |
