全身麻酔と深い鎮静
歯科医院が、全身麻酔または深い鎮静（静脈内鎮静）のもとでの治療を記載しているかどうかです。いわゆる「眠っている間の歯科治療」で、患者は眠った状態で意識がなく、処置を感じることも、見ることも、聞くこともありません。患者が起きたまま受け答えできる通常の意識下鎮静はここには含みません。参考情報であり、透明性のスコアには影響しません。
- ? 全身麻酔・深い鎮静（眠っている間の歯科治療） — 未確認 Ambiguous in the clinic's own material: the sedation-dentistry procedure page states that sedatives "allow the patient to stay awake", while the Meet The Doctors page describes wisdom-tooth extraction under IV sedation. Not resolved to the methodology's asleep-and-unaware definition, so left unverified.
概要
港区麻布台にある自由診療専門の歯科医院で、米国で学んだ歯科医師を中心に運営されています。チーム紹介ページにはニューヨーク大学、UCLA、東京医科歯科大学の学位を持つ歯科医師4名の名が挙がっており、そのなかには口腔外科の専門医と歯周病の専門医も含まれます。設備紹介ページにはSironaのコーンビームCT、デジタル口腔内センサー、Zeissの顕微鏡が記載されており、電話・WhatsApp・メールによる専用の緊急連絡体制も設けています。東京都に歯科診療所として登録されていますが、国の健康保険医療機関の指定リストには載っておらず、治療はすべて自由診療となります。公開されている金額は緊急時の限定検査料38,500円のみで、料金表はありません。

情報の透明性
20 / 20
歯科医院についての基本的な事実、つまり在籍する歯科医師、院内の様子、診療内容、所在地が、公開情報から確認できるかどうかです。
| ✓ | 公式サイトがある [s1] | 4/4 |
| ✓ | 歯科医師名の掲載 Four dentists named on the clinic's own Meet The Doctors page: Dr. Miwako Hayashi, Dr. Yasuhiro Sakamoto, Dr. Hirokazu Enatsu and Dr. Daiki Tanaka. [s2] | 3/3 |
| ✓ | 歯科医師の専門分野の掲載 Board-certified oral and maxillofacial surgeon (specialist and supervising dentist, Japanese Academy of Oral Maxillofacial Surgery), board-certified periodontist (specialist), NYU orthodontics programme, UCLA endodontic continuum. [s2] | 2/2 |
| ✓ | 実際の院内写真 Dedicated office-tour page with photographs of the premises. [s7] | 2/2 |
| ✓ | 診療内容の一覧の公開 Individual procedure pages published by the clinic (exam and cleaning, implants, endodontics, children's dentistry, orthodontics, cosmetic, bonding, whitening, veneers, sedation, bite/occlusion). [s1] [s6] | 3/3 |
| ✓ | 連絡先が明確 Phone, WhatsApp number and an e-mail address for emergencies published on the site. [s1] [s5] | 2/2 |
| ✓ | 英語版のサイト The site is English-first, with one Japanese landing page. [s1] | 2/2 |
| ✓ | 住所と地図の掲載 Street address plus map link and station-by-station directions. [s4] | 2/2 |
料金の透明性
4 / 15
受診前に費用の見当がつくかどうかです。日本では保険診療の料金が全国一律で定められているため、料金の公開は自由診療でとくに意味を持ちます。料金の目安が公開されていれば対象となり、正確な金額の掲載までは求めません。
| ✗ | 料金表または料金の目安の公開 The full page list (site map) carries no fee page; the only figure published is the limited emergency examination fee. A single fee is not a price list under methodology 1.3.1. [s3] [s6] | 0/3 |
| ? | クリーニング・歯石除去の料金の掲載 | 0/2 |
| ? | 詰め物の料金の掲載 | 0/2 |
| ? | 被せ物の料金の掲載 | 0/2 |
| ? | インプラントの料金の掲載 | 0/2 |
| ✓ | 初回相談料の掲載 New-patient page: "Our fee for Limited Exam for emergency patients with one small x-ray and Oral Photo is JPY38,500". [s3] | 2/2 |
| ✓ | レントゲン・画像診断の料金の掲載 Not itemised separately: the clinic states that one small x-ray is included in the published JPY 38,500 limited emergency examination fee. [s3] | 2/2 |
評判と口コミ
17.5 / 20
公開されている口コミの状況です。Googleの評価は、評価4.0を口コミ25件分の重みとするベイズ事前分布で補正します。数件の口コミによる5.0が、数百件の口コミによる4.8を上回らないようにするためです。
| ◐ | Googleの評価（ベイズ補正済み） Star histogram read live on 2026-09-06 from the place page: 110 five-star, 2 four-star, 2 three-star, 0 two-star, 8 one-star. The buckets sum to 122, matching the 122 in the place-page header exactly, and the weighted mean 4.689 reproduces the published 4.7. [gmp1] | 5/6 |
| ◐ | Googleの口コミ件数 Read live on 2026-09-06 from the place-page header; the star histogram sums to the same figure. [gmp1] | 2/3 |
| ✓ | 口コミの新しさ 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; re-checking the Reviews tab returned the same three reviews, so no fresher slice is available. [gmp1] | 3/3 |
| ✓ | 口コミに返信している The owner replies to Google reviews: 1 of the 10 reviews read carry an owner reply, the latest dated 2025-10-05. [azabudai-united-dental-office-tokyo-deepen-5] | 2/2 |
| ✓ | 繰り返される苦情がない None of the three reviews Google renders is critical - all three describe emergency treatment given to visitors at short notice. The histogram carries eight one-star ratings out of 122 (6.6 per cent) that the visible sample cannot reach, so this reading rests on the sample. 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 |
| ✓ | 不自然な口コミの傾向がない Histogram shape, spread of wording and dates, and reviewer-account variety show no sign of manipulation. 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 |
| ✓ | Facebookでの活動がある Facebook page linked from the clinic's own site. [s1] | 1/1 |
| ✗ | TripAdvisorへの掲載 No TripAdvisor listing found via its search for "United Dental Office Azabudai Tokyo" and "United Dental Office"; the clinic's site does not link to TripAdvisor (checked 2026-10-05). [azabudai-united-dental-office-tokyo-tripadvisor] [azabudai-united-dental-office-tokyo-deepen] | 0/0.5 |
| ✓ | その他の口コミサイト Has a claimed Yelp page at 1-7-3 Azabudai, Minato-ku (4.9 from 8 reviews). [azabudai-united-dental-office-tokyo-deepen-4] | 0.5/0.5 |

15 / 15

許認可と資格
歯科医院が、医院の開設許可・届出と、在籍する歯科医師およびその免許登録番号を公開しているかどうかです。公開していないことが確認できた場合はレッドフラグとして記録します。まだ確認していない情報は未確認として表示し、減点はしません。
医院の開設許可・届出: Institution code 3136016800 — registered dental clinic, Tokyo (prefecture code 13), MHLW Healthcare Information Net; operator a medical corporation, facility record last updated 2026/7/6. Corroborated by the MHLW open-data release of the same register, snapshot 2025-12-01. (The clinic is not listed in the Kanto-Shinetsu Regional Bureau of Health and Welfare dental health-insurance institution (hoken iryo kikan) designation list (snapshot Reiwa 8.9.1 = 2026-09-01, 10,292 institutions read to the last row), which is consistent with a purely private-fee practice and is not evidence of a missing licence.)

変更履歴
| 日付 | 変更内容 |
|---|---|
| 2026-10-05 | TripAdvisor presence checked on 2026-10-05: no listing found for this clinic. |
| 2026-10-05 | Read 10 of the clinic's Google reviews on 2026-10-02: the owner replies to reviews. |
| 2026-10-01 | Read on 2026-10-01: the clinic has its own page on a review platform (yelp.com), so it is present on other review platforms. |
| 2026-10-01 | Other review platforms re-checked on 2026-10-01: the Yelp page the clinic links could not be opened, and there is no WhatClinic or Trustpilot profile; onOtherPlatforms set to unknown. |
| 2026-09-29 | Corrected 2026-09-29: clinic responds to reviews now unverified: only 3 reviews were checked for owner replies. |
| 2026-09-07 | Close-out, 2026-09-07: navigation to www.uniteddentaloffice.com, refused to, now works; the clinic's Japanese page was read and the open question — whether it publishes kanji for its two Latin-only dentists — is answered with a negative. |
| 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: geo added from the MHLW Iryo Joho Net open data (snapshot 2025-12-01, facility ID 1333136016800); the managing dentist was re-searched in the MHLW dentist register under the clinic's own kanji spelling of Miwako Hayashi's name and found (Heisei 9 = 1997), and Dr. Hirokazu Enatsu was found from the kanji published on the clinic's Japanese page; the Kanto-Shinetsu Regional Bureau of Health and Welfare dental designation list was re-read to the last of its 10,292 rows and the clinic is confirmed absent; x-ray pricing harmonised with the rest of the country. |
| 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 Kanto-Shinetsu Regional Bureau of Health and Welfare health-insurance designation list and the MHLW dentist qualification search. |
