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
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 Eleven dentists named on the dentist-team page, headed by Yang Teng-Kai. The MOHW institution record counts 6 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. [s2] | 3/3 |
| ✓ | Dentist specializations listed Each entry carries its field, e.g. Yang Teng-Kai — orthodontic specialist, Invisalign Diamond tier; Chen Yi-Chun and Ting Chun-Hsin — paediatric dentistry specialists; Hsu Min-Ta — dental implants, All on 4. [s2] | 2/2 |
| ✓ | Real clinic photos Photographs of the interior, treatment rooms and the children’s corner throughout the site. [s1] | 2/2 |
| ✓ | Service list published The services section lists orthodontics, dental implants, All on 4 one-day full-mouth reconstruction, paediatric specialty care, whitening and all-ceramic aesthetics. [s3] | 3/3 |
| ✓ | Clear contact details Phone, LINE ID, e-mail and address in the footer of every page. [s1] | 2/2 |
| ✗ | English website version Traditional Chinese only, apart from English section headings. [s1] | 0/2 |
| ✓ | Address and map published Address published site-wide with a Google Maps link; matches the MOHW register entry. [s1] [reg1] | 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 No price list or ranges: the navigation has no fee page and the service pages carry no figures. [s1] [s3] | 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 | 0/2 |
| ? | X-ray / imaging price listed | 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: 1798 five-star, 26 four-star, 6 three-star, 2 two-star, 25 one-star. The buckets sum to 1857, matching the 1857 in the place-page header exactly, and the weighted mean 4.922 reproduces the published 4.9. [gmp1] | 6/6 |
| ✓ | Google review volume Read live on 2026-09-06 from the place-page header; the star histogram sums to the same figure. Read from the accessibility labels, not from a comma split: the four-digit bucket 1,798 and the header 1,857 both survive intact, and the buckets sum exactly to the header. [gmp1] | 3/3 |
| ◐ | Review recency The newest review visible is 10 months old, which proves the within-a-year 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] | 1.5/3 |
| ✓ | Clinic responds to reviews The owner replied to the visible reviews individually, naming the treating dentist in the reply. 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 |
| ✓ | No recurring complaints None of the three reviews Google renders is critical; one records that the clinic gives service in English and that appointments are easy to make and reschedule. The histogram carries 25 one-star and 2 two-star ratings out of 1,857 (1.5 per cent) that the visible sample cannot reach - the smallest negative tail in Taiwan. 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 |
| ✓ | No suspicious review patterns The 1798/26/6/2/25 distribution carries a graded tail over a base of more than 1,800 reviews - not the shape manipulation produces. 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 clinic links its own page, facebook.com/littleud298, and its Instagram account. [s1] | 1/1 |
| ✗ | TripAdvisor presence No TripAdvisor listing found via its search for "Little U Dental Kaohsiung" and "Little U Dental"; the clinic's site does not link to TripAdvisor (checked 2026-10-05). [little-u-dental-kaohsiung-tripadvisor] [little-u-dental-kaohsiung-tripadvisor-2] | 0/0.5 |
| ✗ | Other review platforms The Dent&Co profile exists but carries no patient reviews. [s5] | 0/0.5 |
Medical Infrastructure
The range of publicly documented equipment and services. This measures documented availability, not clinical quality.
| ? | On-site X-ray | 0/2 |
| ✓ | CBCT (3D imaging) 3D CBCT (computed tomography) listed under "Environment and equipment", used for implant and orthodontic planning. [s1] | 2/2 |
| ✓ | Implantology Implant and All-on-4 pages; five dentists listed under the implant team. [s3] | 2/2 |

Communication & Service
How easy it is to contact the clinic, get answers, and book - especially for international patients.
