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.

Summary
German-board-certified multi-specialty dental & dermatology clinic in Madinat Khalifa North (officially part of Doha Municipality), operating in Qatar for over 40 years. Offers Invisalign, implants, oral surgery, cosmetic and restorative dentistry with an English/Arabic website.
Checked 2026-09-02: the four licence numbers on file were re-read today on the clinic's own homepage ("Dr. Hana Hasse Orthodontist License No : D276", "Dr. Sven Hasse Orthodontist License No : D276", "Dr. Manfred Laatz Orthodontist License No : D766", "Dr. Dominique Laatz Oral Surgeon License No: D8536"). The site publishes the same number, D276, against two different named orthodontists — two practitioners cannot share one DHP registration, so at least one of the two published numbers is wrong at source. Both are reproduced here exactly as published, and neither could be checked against the DHP register, which is form-/anti-bot gated. The clinic's /our-team/ page returns HTTP 403 to an automated fetch, so the homepage is the citable roster.

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) As of 2026-09-03, live Google Maps place page, re-read in a browser: 4.8 / 2,526 reviews.

Re-read on 2026-09-03 during the reputation pass: unchanged; the published figure reproduces from the star histogram 2376/47/14/10/79 (5*->1*) on the same page. [sm] | 6/6 |

|---|---|
| 2026-10-02 | Read the clinic's Google listing on 2026-10-02 in 2 review orders (10 distinct reviews, dated 2022-08-04 to 2026-10-02; 4.8 from 2525): owner replies true. |
| 2026-09-29 | Corrected 2026-09-29: clinic responds to reviews now unverified: only 8 reviews were checked for owner replies. |
| 2026-09-25 | Re-read on 2026-09-25: the clinic's dental pages (English and Arabic) and the Google listing. Recorded: premises photos, a free first consultation, a panoramic X-ray included in the free implant consultation, X-rays, free consultation booking, clear explanations, MedicalBusiness structured data, opening on Saturdays; no cleaning, filling, crown or implant prices; not on TripAdvisor or WhatClinic. Corrected: recurring complaints are now recorded - low reviews describe charges for X-rays patients saw as unnecessary and a focus on money. Still unverified: CBCT, pediatric dentistry. |
| 2026-09-03 | reputation block assessed from live Maps: reviewRecency=within_3_months, respondsToReviews=false, recurringComplaints=false, suspiciousReviewPatterns=false (8 visible reviews, order relevance (Maps' sort control could not be operated in this browser session), histogram 2376/47/14/10/79 (5*->1*), checked 2026-09-03). |

Identity re-confirmed on the page — address "Al Taif Street Madinat Khalifa North, Al Taif ST, Area # 32, St. #830, Villa #76, Doha" matches the card exactly; the listing shows a second contact number (+974 3029 0013) alongside the switchboard number held on the card. |
| 2026-09-03 | Google rating and review count re-read live in a browser on the Maps place page: 4.8 / 2457 -> 4.8 / 2526. The earlier note claiming a live 2026-09-02 read was false; that pair matched a March-2026 third-party copy exactly. Provenance corrected. |
