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

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 Our Dentists page names thirteen dentists including Dr. Alex Chang, Lin Yi-Ting, Tseng Jen-Hung, Kao Chia-Kuang, Ko Han-Hsin, Li Chien-Hao and Kao Wei-Ling; the MOHW staffing record counts six registered at these premises. [s2] | 3/3 |
| ✓ | Dentist specializations listed Each entry carries training and society certifications across implantology, orthodontics, endodontics and prosthodontics, e.g. Dr. Alex Chang (DDS, UCLA) implants and orthodontics. [s2] | 2/2 |
| ✓ | Real clinic photos Our Space page showing the clinic's own premises. [s3] | 2/2 |
| ✓ | Service list published [s1] [s6] | 3/3 |
| ✓ | Clear contact details Phone and address published on the site match the MOHW institution record and the NHI contracted-clinic file. [s1] [reg1] | 2/2 |
| ✓ | English website version A complete English site at /en/ mirroring the Chinese one. [s1] | 2/2 |
| ✓ | Address and map published Traffic-information page with directions and map links. [s5] [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 The consulting-hour page and the service pages were read; no price list, ranges or consultation fee is published on the clinic's own channels. [s4] [s6] | 0/3 |
| ✗ | Cleaning price listed [s6] | 0/2 |
| ✗ | Filling price listed [s6] | 0/2 |
| ✗ | Crown price listed [s6] | 0/2 |
| ✗ | Implant price listed [s6] | 0/2 |
| ✗ | Consultation price listed [s4] | 0/2 |
| ✗ | X-ray / imaging price listed [s6] | 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) as of 2026-10-05 [qdo-dental-taichung-deepen] | 6/6 |
| ✓ | Google review volume [qdo-dental-taichung-deepen] | 3/3 |
| ✓ | Review recency The newest review visible is 3 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, 2 of them recent (within the last 12 months), the latest reply dated 2026-05-25. [qdo-dental-taichung-deepen] | 2/2 |
| ✓ | No recurring complaints None of the three reviews Google renders is critical; one explicitly records that there was no overselling of services or products. The histogram carries 90 one-star and 12 two-star ratings out of 3,229 (3.2 per cent) that the visible sample cannot reach. 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 3064/54/9/12/90 distribution carries a full, graded tail over the largest review base in either of this agent's two countries - 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 [s1] | 1/1 |
| ✗ | TripAdvisor presence No TripAdvisor listing found via its search for "QDO Dental Clinic Taichung" and "QDO Dental"; the clinic's site does not link to TripAdvisor (checked 2026-10-05). [qdo-dental-taichung-tripadvisor] [qdo-dental-taichung-tripadvisor-2] | 0/0.5 |
| ✓ | Other review platforms Reviewed on Dent&Co, Taiwan's dental review and booking site (7 clinic reviews and 186 reviews of its dentists). [qdo-dental-taichung-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 The equipment page documents CT scanning but names no plain radiography unit. | 0/2 |
| ✓ | CBCT (3D imaging) Dental CT scan documented on the clinic's own equipment page, alongside X-Guide dynamic 3D implant navigation. [s7] | 2/2 |
| ✓ | Implantology [s6] [s7] | 2/2 |
| ✓ | Orthodontics Named orthodontic providers with certification, and orthodontics in the published service list. [s2] [s6] | 2/2 |
| ✓ | Oral surgery Biolase Waterlase laser surgery and X-Guide navigated implant surgery, with a named oral-surgery provider on the roster. [s2] [s7] | 2/2 |
| ? | Pediatric dentistry | 0/1.5 |
| ? | Emergency care | 0/1.5 |
| ✓ | Works with international patients The clinic maintains a complete English site and presents dentists trained in the United States, Germany, Japan and Canada. [s1] [s2] | 2/2 |
Communication & Service
How easy it is to contact the clinic, get answers, and book - especially for international patients.
| ✓ | WhatsApp / LINE available LINE official account published as a contact channel. [s1] [s4] | 2/2 |

| ✓ | Convenient opening hours Weekday evening sessions 18:30-21:00 and Saturday morning and afternoon clinics, published by the clinic and corroborated by the National Health Insurance session grid. [s4] [nhi1] | 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 Taiwan", "English speaking dentist Taiwan", "dental implants Taiwan", "emergency dentist Taiwan", "Taiwan dental clinic for expats".
| ✗ | Mentioned for: best dentist Taiwan [sqb] | 0/1 |

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: Institution code 3703270216 — QDO Dental Clinic, private dental clinic, operating status: operating, 1F, No. 251-4, Section 2, Xitun Road, Xitun District, Taichung; NHI-contract flag: yes. MOHW medical institution search, checked 2026-09-04. National Health Insurance contract running since 2016-01-29 per the NHI contracted-clinic open dataset refreshed 2026-09-04. (The institution code is Taiwan's published licence-side identifier and only currently operating institutions appear in the register. The clinic does not publish this code on its own site. The MOHW staffing record counts six registered dentists against the thirteen the clinic names; the register records one primary practice registration per dentist and never links a person to a clinic, so the difference is expected for a practice that uses visiting specialists.)

Change History
| Date | Change |
|---|---|
| 2026-10-05 | Tied this card to the clinic's own Google listing (same street address and telephone number) and read it on 2026-10-05 in 2 review orders (10 distinct reviews, dated 2019-12-20 to 2026-10-05; 4.8 from 2918): owner replies true. Google rating and review count updated to 4.8 from 2918 (was 4.9 from 3229). |
| 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. |
| 2026-09-11 | Rechecked whether this practice answers its Google reviews. No single Google listing is on record for it (the link held is a name search), so the criterion was left unscored instead of credited. |
| 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 own channels. |
| 2026-09-04 | Initial data collection for the Taiwan Dental Transparency & Trust Index: verified against the clinic's own English and Chinese sites, the MOHW institution and personnel registers, and the National Health Insurance contracted-clinic open data. Google Maps figures deferred to a manual browser check. |
