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 The services page says surgery is performed under sedation in cooperation with an anaesthetist; the depth is not published and the page does not claim general anaesthesia.

情報の透明性
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 |

料金の透明性
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。
評判と口コミ
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: 47 five-star, 0 four-star, 0 three-star, 0 two-star, 2 one-star. The buckets sum to 49, matching the 49 in the place-page header exactly, and the weighted mean 4.837 reproduces the published 4.8. [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] | 1/3 |
| ◐ | 口コミの新しさ Newest Google review is dated 2026-05-19 (listing read 2026-09-26). [dental-office-otani-umeda-osaka-gbp-2026-09-26] | 1.5/3 |
| ? | 口コミに返信している | 0/2 |
| ✓ | 繰り返される苦情がない No review in the visible sample is critical; the histogram carries two one-star ratings in 49 (4 per cent). 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 The clinic's Facebook page has had no post since April 2020 and has no reviews; the clinic's website doo.or.jp is its working channel. [dental-office-otani-umeda-osaka-presence-2] | 0/1 |

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. |
| 2026-10-02 | Facebook presence re-checked on 2026-10-02: the clinic's Facebook page is inactive. |
| 2026-10-02 | Presence re-checked: presence on other review platforms — yes. |
| 2026-09-29 | Corrected 2026-09-29: clinic responds to reviews now unverified: only 3 reviews were checked for owner replies; review recency within a year (newest review dated 2026-05-19). |
| 2026-09-09 | Sedation criterion re-read against methodology 1.4.0, which counts only general anaesthesia or deep intravenous sedation where the patient is asleep and unaware. The services page says surgery is performed under sedation in cooperation with an anaesthetist; the depth is not published and the page does not claim general anaesthesia. The value moves from true to unknown: the earlier reading credited sedation that is not documented as deep enough, and the published wording settles the question neither way. |
| 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 2733270081040); the Kinki Regional Bureau of Health and Welfare Osaka dental list re-downloaded and re-read to the last of its 5,240 rows, entry 3164 (institution code 41-07929, designated Heisei 29.3.1 = 2017-03-01, operator: a medical corporation (iryo hojin) whose chairman has the same surname in kanji as the director; managing dentist Takafumi Otani) reproduced exactly; the principal's register entry (Heisei 16 = 2004) reproduced live. |
| 2026-09-04 | Initial data collection for the Japan Dental Transparency & Trust Index: verified against the clinic's own website, the Kinki Regional Bureau of Health and Welfare health-insurance designation list, the MHLW Iryo Joho Net facility register and its open-data twin, and the MHLW dentist qualification search. |
