General Anaesthesia & Deep Sedation

Score Breakdown
Every criterion below is scored from public sources. ✓ verified yes · ✗ verified no / not found · ◐ partial · ? unverified (scores 0, not a negative finding).

Price Transparency
Whether patients can estimate costs before visiting. Published price ranges count; exact prices are not required.
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) Star histogram read live on 2026-09-07 from the place page: 95 five-star, 2 four-star, 1 three-star, 1 two-star, 5 one-star. The buckets sum to 104, matching the 104 in the place-page header exactly, and the weighted mean 4.740 reproduces the published 4.7. [gmp1] | 5/6 |
| ◐ | Google review volume Read live on 2026-09-07 from the place-page header; the star histogram sums to the same figure. The card previously held 104, read on 2026-08-25 — the listing has not moved since. [gmp1] | 2/3 |
| ✓ | Review recency The newest review visible is 3 months old, which proves the within-3-months bucket and no better; the Newest sort does not open to automation in Maps, so the true newest review may be more recent than this. Sample: the 3 reviews Google Maps renders on the place page in its own relevance order. [gmp1] | 3/3 |
| ✓ | Clinic responds to reviews The owner replied to two of the three reviews Google renders, briefly and by name; the third, three months old, carries no reply. Sample: the 3 reviews Google Maps renders on the place page in its own relevance order. [gmp1] | 2/2 |
| ✓ | No recurring complaints No repeated complaint theme appears in the visible sample: all three reviews are five-star and none is critical. The unread negative tail is 5 one-star and 1 two-star rating out of 104 — 5.8 per cent of the base. Sample: the 3 reviews Google Maps renders on the place page in its own relevance order. [gmp1] | 2/2 |
| ✓ | No suspicious review patterns The 95/2/1/1/5 spread carries reviews in every one of the five buckets, the three visible reviewers include a Local Guide holding 425 reviews and 557 photos, and their dates span three months to two years. Sample: the 3 reviews Google Maps renders on the place page in its own relevance order. [gmp1] | 2/2 |
| ✓ | Active Facebook presence [s1] | 1/1 |
| ? | TripAdvisor presence | 0/0.5 |
| ✓ | Other review platforms [s1] | 0.5/0.5 |

This card enters the country directory southafrica-dental as a twin of this city site and carries no entry in data/research/*.json (johannesburg-dental has no research directory at all — this card in clinics.json is the sole record), so import-research.js never had a file to read this field from; it stayed null through the whole of until measured directly here.

The manual browser check could not reach these ten cards: they enter the country directory southafrica-dental as twins of this city site, carry no entry in data/research/*.json, and import-research.js therefore left them untouched, so their respondsToReviews, recurringComplaints and suspiciousReviewPatterns had never been assessed at all.
