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.

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
18 / 20
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 Seventeen dentists named on the medical-team section, headed by Wang Chih-Yang (director) with Yang Jung-Wu as honorary consultant. The MOHW institution record counts 8 dentists registered at these premises (checked 2026-09-04); the register never publishes their names, so the published roster and the registration count cannot be reconciled from any official source. [s1] | 3/3 |
| ✓ | Dentist specializations listed The group roster on the sister clinic’s "About us" page assigns a specialty to each name (oral and maxillofacial surgery: Kang Chia-Chun, Huang Yi-Chia; orthodontics: Kuo Ting-Yu; periodontics: Liu Chia-Ling and others). [s2] | 2/2 |
| ✓ | Real clinic photos The clinic-introduction page carries photographs of the premises. [s3] | 2/2 |
| ✓ | Service list published The main-treatments section lists dental implants, general dentistry, periodontal treatment, full-mouth reconstruction, denture making, root-canal treatment, clear-aligner orthodontics, clear aligners, orthodontics, wisdom-tooth removal, cleaning, extraction and whitening. [s1] | 3/3 |
| ✓ | Clear contact details Address, phone and service hours in the contact block of every page, plus a note on the nearest car park. [s1] | 2/2 |
| ✗ | English website version An /en/ path exists but serves the same Traditional Chinese content; only section headings are in English. [s1] | 0/2 |
| ✓ | Address and map published Address published with a "navigate there" map link; matches the MOHW register entry. [s1] [reg1] | 2/2 |
Price Transparency
2 / 15
Whether patients can estimate costs before visiting. Published price ranges count; exact prices are not required.
| ✗ | Prices or price ranges published The clinic publishes its registration fee but no price list or ranges for treatments; there is no fee page. [s1] | 0/3 |
| ? | Cleaning price listed | 0/2 |
| ? | Filling price listed | 0/2 |
| ? | Crown price listed | 0/2 |
| ? | Implant price listed | 0/2 |
| ✓ | Consultation price listed Stated on the timetable page: registration fee NT$200 plus statutory co-payment NT$50, NT$250 in total, revised with effect from 1 January 2026 (ROC year 115). [s1] | 2/2 |
| ? | X-ray / imaging price listed | 0/2 |
Reputation & Reviews
14.5 / 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) as of 2026-10-05 [yuan-yuan-hao-dental-tainan-deepen] | 4/6 |
| ◐ | Google review volume [yuan-yuan-hao-dental-tainan-deepen] | 2.5/3 |
| ✓ | Review recency The newest review visible is 2 months old, which proves the within-3-months bucket and no better. Sample: the three reviews Google Maps renders on the place page in its own relevance order; a newest-first list was not available. [gmp1] | 3/3 |
| ✓ | Clinic responds to reviews The owner replies to Google reviews: 3 of the 10 reviews read carry an owner reply, 3 of them recent (within the last 12 months), the latest reply dated 2026-05-04. [yuan-yuan-hao-dental-tainan-deepen] | 2/2 |
| ? | No recurring complaints 1–2★ ratings are 44 of 393 (11.2 %), but the lowest-rated reviews read show no shared theme: three of them, posted on 2026-05-01 and 2026-05-02, describe one extraction case (pain dismissed at the follow-up, a dry socket found elsewhere), and the other two concern a five-minute cleaning and a denture consultation. [yuan-yuan-hao-dental-tainan-deepen] | 0/2 |
| ✓ | No suspicious review patterns The 330/7/10/13/31 distribution carries a full, graded tail rather than the clean five-star wall manipulation produces, and its shape differs markedly from the sister clinic's next door, which is what independent patient bases look like. Sample: the three reviews Google Maps renders on the place page in its own relevance order; a newest-first list was not available. [gmp1] | 2/2 |
| ✓ | Active Facebook presence The group site links this clinic’s own page, facebook.com/yyddental01, and its Instagram account. [s4] | 1/1 |
| ✗ | TripAdvisor presence No TripAdvisor listing found via its search for the clinic's name and a short form of it; the clinic's site does not link to TripAdvisor (checked 2026-10-05). [yuan-yuan-hao-dental-tainan-tripadvisor] [yuan-yuan-hao-dental-tainan-tripadvisor-2] | 0/0.5 |
| ✗ | Other review platforms The Dent&Co profile exists but carries no patient reviews. [s5] | 0/0.5 |
Medical Infrastructure
8 / 15
The range of publicly documented equipment and services. This measures documented availability, not clinical quality.
| ? | On-site X-ray | 0/2 |
| ✓ | CBCT (3D imaging) A Finnish 3D cone-beam CT unit listed among the clinic’s equipment. [s1] | 2/2 |
| ✓ | Implantology Astra, ET and Ankylos implant systems documented; dental implants on the service list. [s1] | 2/2 |
| ✓ | Orthodontics Clear-aligner orthodontics and conventional orthodontics named as core treatments, with 3D-printed aligners. [s1] | 2/2 |
| ✓ | Oral surgery Difficult extractions named as a core treatment; the group roster includes three oral and maxillofacial surgeons. [s1] [s2] | 2/2 |
| ✗ | Pediatric dentistry Children’s dentistry is not among this clinic’s published treatments; the group runs its paediatric rota at the sister clinic. [s1] | 0/1.5 |

| ✓ | Pre-visit consultation possible The timetable page asks patients to call (06) 222-9919 to confirm a dentist’s sessions before attending. [s1] | 1.5/1.5 |
| ✓ | Clear service explanations The clinic sets out its equipment and core treatments in plain language and states the registration deadline (arrive at least 30 minutes before the session ends). [s1] | 1/1 |
| ✓ | Convenient opening hours Published: morning 09:00–12:00, afternoon 14:00–17:00 and evening 18:00–21:00, Monday to Saturday, with a per-dentist rota updated 2 September 2026. [s1] | 1.5/1.5 |
AI & Search Visibility
3.5 / 10
Whether the clinic is discoverable when patients search - including via AI assistants. Checked with fixed queries: "best dentist Taiwan", "English speaking dentist Taiwan", "dental implants Taiwan", "emergency dentist Taiwan", "Taiwan dental clinic for expats".
| ✗ | Mentioned for: best dentist Taiwan Web search 2026-09-06: not among results for "best dentist Tainan". The answer names a "Yuan Yuan Dental Clinic" from a highly reviewed.online listing, but that clinic's name is written with different characters (yuan yuan, "round") from this clinic's registered name (Yuan Yuan Hao, "far-reaching source") — treated as a namesake, not a match. [sq1] | 0/1 |
| ✗ | Mentioned for: English speaking dentist Taiwan Web search 2026-09-06: not among results for "English speaking dentist Tainan"; the answer states results for Tainan specifically were limited and points to the AIT directory instead of a named clinic. [sq2] | 0/1 |
| ✗ | Mentioned for: dental implants Taiwan Web search 2026-09-06: not among results for "dental implants Tainan" (top result was Mu Shan Hao Dental Clinic). [sq3] | 0/1 |
| ✗ | Mentioned for: emergency dentist Taiwan Web search 2026-09-06: not among results for "emergency dentist Tainan" (named results were Kaohsiung VGH Tainan Branch and Mu Shan Hao Dental Clinic). [sq4] | 0/1 |
| ✗ | Mentioned for: Taiwan dental clinic for expats Web search 2026-09-06: not among results for "Tainan dental clinic for expats" (named results were Mu Shan Hao Dental Clinic, Kaohsiung VGH Tainan Branch, Tainan Municipal Hospital). [sq5] | 0/1 |
| ✓ | Structured data on website schema.org JSON-LD present in the page source. [s1] | 1.5/1.5 |
| ✓ | Google indexing quality own-brand domains (the group site yyd.com.tw, 2 pages, and a sibling domain yuenyuen-dental.com.tw) hold 3 of 8 results from position 2, behind only a job-listing page; note the exact subdomain on file (yuanyuan.yyd.com.tw) did not itself appear, though the parent domain did (web search 2026-09-07) [giq1] | 2/2 |
| ✗ | Dedicated service pages Treatments are listed as one block in the main-treatments section; there is no page per service. [s1] | 0/1.5 |

Red Flags
- low Aggressive marketing practices (-1 pts) — The clinic's own site hard-codes a schema.org aggregateRating into its markup: ratingValue 5 over reviewCount 58,629, byte-identical to the block on its sister clinic's site. The live Google Business Profile, read on 2026-09-06, shows 4.5 from 391 reviews — the declared volume is 150 times the real one, and the declared perfect five is not the rating the profile carries. Nothing was taken from the declared block: this card's rating and review count come from the place page. [s1] [gmp1]
Red-flag penalty applied: -1 points (capped at -20).
