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
Summary
Referral-style specialist clinic three minutes from Osaka/Umeda station, opened in 2019 and limited to periodontal and implant treatment: it declines general dentistry and refers those cases out, and it explains on its own site why it works entirely outside the national health-insurance system. Its founder, Dr. Shota Tsuji, completed the periodontics residency at Columbia University, is a Diplomate of the American Board of Periodontology and holds a Washington State dental licence alongside a teaching post at Osaka University. Only one figure is published — a JPY 55,000 first-visit package covering the examination and the consultation across two appointments — with treatment fees quoted after diagnosis.
Strengths
- Information Transparency: 20 of 20 points.

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
20 / 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 Shota Tsuji, founder and managing dentist. [s2] | 3/3 |

| ✓ | Address and map published [s4] | 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 Only the first-visit package is priced; the clinic states that treatment fees are quoted at the second appointment after diagnosis. [s5] | 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 First-visit fee JPY 55,000 including tax, covering the examination and consultation across the first two appointments with no further charge before treatment starts. [s5] | 2/2 |

Reputation & Reviews
9.5 / 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) Star histogram read live on 2026-09-06 from the place page: 10 five-star, 0 four-star, 0 three-star, 0 two-star, 4 one-star. The buckets sum to 14, matching the 14 in the place-page header exactly, and the weighted mean 3.857 reproduces the published 3.9. [gmp1] | 1/6 |
| ◐ | Google review volume as of 2026-09-26; previously 14 [spido-periodontics-implant-clinic-umeda-osaka-gbp-2026-09-26] | 0.5/3 |
| ✓ | Review recency The newest review visible is 2 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; re-checking 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 two of the 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; re-checking the Reviews tab returned the same three reviews, so no fresher slice is available. [gmp1] | 2/2 |
| ? | No recurring complaints Deliberately left unknown. Four of the fourteen ratings - 29 per cent of the base - are one-star, so recording 'no recurring complaints' as false would credit a clean record the distribution contradicts; but all three reviews Google renders are five-star, so no negative is readable and no theme can be demonstrated either. Sample: the 3 reviews Google Maps renders on the place page in its own relevance order. A newest-first sort was not available; re-checking the Reviews tab returned the same three reviews, so no fresher slice is available. | 0/2 |
| ✓ | No suspicious review patterns The 10/0/0/0/4 shape is a small, sharply divided base rather than 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; re-checking the Reviews tab returned the same three reviews, so no fresher slice is available. [gmp1] | 2/2 |
| ✓ | Active Facebook presence Facebook page "SPIDO periodontics clinic" (652 followers) with posts up to 2026-06-04, found under the clinic's name; its About section gives the clinic's address, phone and website. [spido-periodontics-implant-clinic-umeda-osaka-presence-4] | 1/1 |
| ✗ | TripAdvisor presence No TripAdvisor listing found via its search for "SPIDO Periodontics Osaka" and "SPIDO Dental"; the clinic's site does not link to TripAdvisor (checked 2026-10-05). [spido-periodontics-implant-clinic-umeda-osaka-tripadvisor] [spido-periodontics-implant-clinic-umeda-osaka-tripadvisor-2] | 0/0.5 |
| ✗ | Other review platforms No review profile on the Japanese review sites: Caloo and EPARK Dental list it only from public data, with no review, and WhatClinic has no page for it (checked 2026-10-02).

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 3270086930 — registered dental clinic, Osaka (prefecture code 27), MHLW Healthcare Information Net; founder and managing dentist Shota Tsuji, facility record last updated 2026/3/9. Corroborated by the MHLW open-data release of the same register, snapshot 2025-12-01. (The clinic is absent from the Kinki Regional Bureau of Health and Welfare dental health-insurance institution (hoken iryo kikan) designation list as of 2026-09-01 (5,240 institutions read to the last row). That is consistent with its own statement that it works entirely outside the health-insurance system, and is not evidence of a missing licence.) [reg1] [reg2] [reg4]

|---|---|
| 2026-10-05 | TripAdvisor presence checked on 2026-10-05: no listing found for this clinic. |
| 2026-10-02 | Facebook presence re-checked on 2026-10-02: live Facebook page confirmed. |
| 2026-10-02 | Presence re-checked: presence on other review platforms — no. |
| 2026-09-29 | Corrected 2026-09-29: review count 15 (was 14) from the Google listing on 2026-09-26. |
| 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 | Adversarial verification pass 2026-09-04: the Kinki Regional Bureau of Health and Welfare Osaka dental list re-read to the last of its 5,240 rows and the clinic confirmed absent (searched by telephone, name, operator and managing dentist), consistent with its published self-pay-only policy; the licence search re-run under both gender filters; geo left null because the clinic's own record in the MHLW open data carries the placeholder coordinates 0.0 / 0.0 — queued for a manual browser check. The English name Specialized Periodontics and Implant Dentistry Osaka is the facility's own declaration in the statutory register, not an invented romanisation. |
| 2026-09-04 | Initial data collection for the Japan Dental Transparency & Trust Index: verified against the clinic's own website, the MHLW Iryo Joho Net facility register and its open-data twin, the Kinki Regional Bureau of Health and Welfare health-insurance designation list and the MHLW dentist qualification search. |
