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 "Sedation dentistry" is listed as a service, but the clinic does not say whether it is general anaesthesia or deep intravenous sedation rather than conscious sedation, which would not count.
Summary
English-first clinic in the Songdo International Business District, founded in 2018 to serve Incheon's international community. Three directors hold Korean Ministry of Health board certifications alongside US degrees (Michigan, UPenn), the clinic bills several foreign insurers directly, and it publishes both a Korean and an English contact route. Registered with HIRA as Seoul Misigan Yupen Chigwa-uiwon, provider code 31588557, opened 2018-01-05.
The clinic publishes both name forms itself — the Latin "Seoul Michigan UPenn Dental Clinic" throughout the site and the Hangul address block (153 Sinsong-ro, The Marantz 4F) plus a KakaoTalk handle written in Hangul (@Seoul Misigan); each director is named in both scripts by the clinic. The chief director appears on the site as both "Dr. Byung Hoon Lee" and "Dr. Andrew B. Lee" beside the same Hangul name (Lee Byeong-hun) and the same credentials. Coordinates come from the clinic's entry in the HIRA national institution register, not from a Google Maps place page — Google Maps and Google Search returned no place data on the date of reading, so all Google-derived reputation fields are left unverified and the place page is.

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.
| ✓ | Has a working website [s1] | 4/4 |
| ✓ | Dentist names listed Three directors named in Hangul and Latin on the clinic's own About page: Byung Hoon Lee, Bok Sil Jang and Jung Joo Park. [s2] | 3/3 |
| ✓ | Dentist specializations listed Byung Hoon Lee — implantology and oral surgery, DDS University of Michigan, MS in oral & maxillofacial surgery, ICOI board certified; Bok Sil Jang — Korean Ministry of Health board-certified prosthodontics specialist, DDS and PhD Seoul National University; Jung Joo Park — Korean Ministry of Health and American Board of Orthodontics certified orthodontist, DMD UPenn. [s2] | 2/2 |
| ✓ | Real clinic photos [s1] | 2/2 |
| ✓ | Service list published General dentistry, cleaning and check-ups, cavities, root canal, extractions, fillings, TMJ, night guards, sealants, sleep apnoea, oral cancer screening, cosmetic and restorative work, implants, crowns, dentures, bridges, veneers, orthodontics and Invisalign, prosthodontics, paediatric dentistry, gum surgery and pinhole gum surgery, wisdom teeth. [s1] | 3/3 |
| ✓ | Clear contact details Landline 032-858-2280, mobile and WhatsApp 010-4658-2280, e-mail and a KakaoTalk channel; the landline matches the HIRA register. [s3] | 2/2 |
| ✓ | English website version The whole site is in English; the clinic describes itself as an English-first practice with bilingual staff. [s1] | 2/2 |
| ✓ | Address and map published Road-name address in Latin and Hangul, subway and airport directions, and parking instructions. [s3] | 2/2 |
Price Transparency
Whether patients can estimate costs before visiting. Published price ranges count; exact prices are not required.
| ✗ | Prices or price ranges published Re-checked 2026-09-04: no figure appears anywhere on the clinic’s own pages. The homepage banner "Check out our latest specials here" links to https://www.dntlbar.com/specials/ - a different domain (DNTL BAR), left over from the site template - so it is not this clinic’s price list at all and cannot be read as a promotion of its own either. [s1] [s3] | 0/3 |
| ✗ | Cleaning price listed [s1] | 0/2 |
| ✗ | Filling price listed [s1] | 0/2 |
| ✗ | Crown price listed [s1] | 0/2 |
| ✗ | Implant price listed [s1] | 0/2 |
| ✗ | Consultation price listed [s1] | 0/2 |
| ✗ | X-ray / imaging price listed [s1] | 0/2 |
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: 260 five-star, 3 four-star, 0 three-star, 0 two-star, 1 one-star. The buckets sum to 264, matching the 264 in the place-page header exactly, and the weighted mean 4.973 reproduces the published 5. [gmp1] | 6/6 |
| ◐ | Google review volume as of 2026-09-26; previously 264 [seoul-michigan-upenn-dental-incheon-gbp-2026-09-26] | 2.5/3 |
| ✓ | Review recency The newest review visible is 3 months old, which proves the within-3-months bucket and no better. Sample: the 3 reviews Google Maps renders on the place page in its own relevance order. A newest-first sort was not available; a re-check on the Reviews tab returned the same three reviews, so no fresher slice is available. [gmp1] | 3/3 |
| ✓ | Clinic responds to reviews The owner replied to all three reviews Google renders. Sample: the 3 reviews Google Maps renders on the place page in its own relevance order. A newest-first sort was not available; a re-check on the Reviews tab returned the same three reviews, so no fresher slice is available. [gmp1] | 2/2 |
| ✓ | No recurring complaints None of the three reviews Google renders is critical, and the histogram carries a single one-star rating in 264 (0.4 per cent). Sample: the 3 reviews Google Maps renders on the place page in its own relevance order. A newest-first sort was not available; a re-check on the Reviews tab returned the same three reviews, so no fresher slice is available. [gmp1] | 2/2 |
| ✓ | No suspicious review patterns 5.0 from 264 was examined rather than assumed. The distribution is not a clean five-star wall - it carries three four-star and one one-star rating - the three visible reviews differ completely in length, register and treatment described (crowns priced against a US dentist, a decade-long patient relationship, veneers), and the owner answers every one of them. A high rating on a Songdo expat clientele writing single reviews after one course of treatment is the expected shape here, not a manipulation signature. Sample: the 3 reviews Google Maps renders on the place page in its own relevance order. A newest-first sort was not available; a re-check on the Reviews tab returned the same three reviews, so no fresher slice is available. [gmp1] | 2/2 |
| ✓ | Active Facebook presence Active Facebook page, linked from the clinic's website: newest post 1 October 2026. [seoul-michigan-upenn-dental-incheon-presence-2] | 1/1 |
| ✗ | TripAdvisor presence No TripAdvisor listing found via its search for "Seoul Michigan UPenn Dental Clinic Incheon" and "Seoul Michigan UPenn"; the clinic's site does not link to TripAdvisor (checked 2026-10-05). [seoul-michigan-upenn-dental-incheon-tripadvisor] [seoul-michigan-upenn-dental-incheon-tripadvisor-2] | 0/0.5 |
| ✓ | Other review platforms Listed on Naver Place, South Korea's main local review platform, with 458 visitor reviews. [seoul-michigan-upenn-dental-incheon-presence] | 0.5/0.5 |
Medical Infrastructure
The range of publicly documented equipment and services. This measures documented availability, not clinical quality.
| ✓ | On-site X-ray HIRA's equipment register records a cone-beam CT at this institution; the clinic documents X-ray and digital imaging. [reg2] [s1] | 2/2 |
| ✓ | CBCT (3D imaging) Returned by the HIRA institution search filtered on equipment code 12 (cone-beam CT) for Incheon / dental clinic. [reg2] | 2/2 |
| ✓ | Implantology [s1] [s2] | 2/2 |
| ✓ | Orthodontics Invisalign, Incognito lingual braces and complex bite correction under a dual board-certified orthodontist. [s1] [s2] | 2/2 |
| ✓ | Oral surgery Wisdom tooth extraction, gum surgery, pinhole gum surgery and full-arch implant rehabilitation. [s1] [s2] | 2/2 |
| ✓ | Pediatric dentistry Paediatric dentistry is a listed specialist service. [s1] | 1.5/1.5 |
| ✗ | Emergency care No emergency or same-day route is documented; the clinic is closed Thursdays and Sundays. [s3] | 0/1.5 |
| ✓ | Works with international patients Founded for Songdo's expatriate community; bills Cigna, Aetna, BCBS Delta and Blue Cross among other foreign insurers, and names the international campuses and employers it serves. [s1] [s3] | 2/2 |
Communication & Service
How easy it is to contact the clinic, get answers, and book - especially for international patients.

| ✓ | Clear service explanations [s1] | 1/1 |
| ✓ | Convenient opening hours Mon–Wed and Fri 09:30–18:30, Sat 09:30–14:00; closed Thursdays and Sundays. [s3] | 1.5/1.5 |
AI & Search Visibility
Whether the clinic is discoverable when patients search - including via AI assistants. Checked with fixed queries: "best dentist Korea", "English speaking dentist Korea", "dental implants Korea", "emergency dentist Korea", "Korea dental clinic for expats".
| ✓ | Mentioned for: best dentist Korea [sq] | 1/1 |

Licensing & Credentials
Whether the clinic publishes its operating licence and the dentists working there together with their professional licence numbers. A verified “not published” is recorded as a red flag; data we have not checked yet is shown as unverified and carries no penalty.
Clinic operating licence: HIRA provider code 31588557 — Seoul Michigan UPenn Dental Clinic, dental clinic, individually owned, opened 2018-01-05, registered with HIRA at Incheon, Yeonsu-gu, Sinsong-ro 153, The Marantz Tower, Units 404,405,406 (Songdo-dong). (Verified live on 2026-09-04 in the HIRA register's detailed-criteria institution search (region = Incheon, type = dental clinic, institution name = 'Seoul Misigan Yupen'): exactly one result, whose address and landline match the clinic's own Location & Hours page. The clinic publishes no business registration number. Korea has no clinic operating-licence number separate from the HIRA provider code, and the register is queried live, so no snapshot date applies. Searched in Hangul, as romanisation does not work in Korean registers.) [reg1] [s3]

Change History
| Date | Change |
|---|---|
| 2026-10-05 | TripAdvisor presence checked on 2026-10-05: no listing found for this clinic. |
| 2026-10-02 | Presence re-checked: presence on other review platforms — yes; Facebook presence — yes. |
| 2026-09-29 | Corrected 2026-09-29: active Facebook presence now unverified: no Facebook search is on record, so the absence of a page is not established; review count 280 (was 264) from the Google listing on 2026-09-26. |
| 2026-09-06 | Data gate: the canonical city query "English speaking dentist Incheon" was re-run with web search because the initial data collection had run a form narrowed to the Songdo district. aiMention_englishSpeaking was re-evaluated against the canonical run and now cites it. |
| 2026-09-06 | Checked by hand in a browser: the Google Maps place page was opened in a real browser and read for rating, review count, star histogram, review recency, owner replies, complaint and manipulation reading, listing website, phone, address and pin coordinates; the checks that needed a rendering browser were worked through on the clinic's own channels. |
| 2026-09-04 | Initial data collection for the Korea Dental Transparency & Trust Index: verified via songdodentalclinic.com (homepage, About and Location & Hours) and against the HIRA national institution register (provider code 31588557). No public per-dentist licence search exists in South Korea, so the three directors' licence numbers are recorded as unverified rather than as a negative finding. Google Maps reputation fields and the map pin were not obtainable automatically and are queued for a manual browser check. |
