全身麻酔と深い鎮静

料金の透明性
13 / 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 Permanent private-fee table (tax exclusive) across diagnosis, periodontal regeneration, implants, aesthetic restoration, gold restorations and whitening. [s3] | 3/3 |
| ✗ | クリーニング・歯石除去の料金の掲載 Cleaning is offered but not priced in the published fee table. [s3] | 0/2 |

評判と口コミ
13 / 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: 86 five-star, 2 four-star, 2 three-star, 3 two-star, 10 one-star. The buckets sum to 103, matching the 103 in the place-page header exactly, and the weighted mean 4.466 reproduces the published 4.5. [gmp1] | 4/6 |
| ◐ | 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 None of the 17 reviews read on Google carries an owner reply, including the 12 dated 2025-02-25 to 2026-09-29. [duo-osaka-dental-clinic-nakanoshima-osaka-deepen] | 0/2 |
| ✓ | 繰り返される苦情がない None of the three reviews Google renders is critical. The histogram carries thirteen ratings of two stars or below out of 103 (12.6 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 The clinic's Facebook page has had no post since July 2022 and has eight reviews; the clinic's website duo-dental.com is its working channel. [duo-osaka-dental-clinic-nakanoshima-osaka-presence-4] | 0/1 |
| ? | TripAdvisorへの掲載 | 0/0.5 |
| ✗ | その他の口コミサイト No review profile on the Japanese review sites: Caloo lists it only from the public register, with no review; EPARK Dental and WhatClinic have no page for it (checked 2026-10-02).
