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.
- ✗ General anaesthesia / deep sedation (sleep dentistry) — No general anaesthesia or deep sedation documented Nitrous-oxide conscious sedation (paediatric) only; no general anaesthesia or deep sedation is offered. [margraf-dental-health-center-asuncion-g5]
Summary
Dental centre in Villa Morra founded by Prof. Dr. Marcos Margraf, who has practised in Paraguay for about fifteen years after an international career. The clinic moved into a purpose-built site at Moisés Bertoni and Dr. Weiss, reported by Forbes Paraguay as having eight clinical surgeries, a surgical centre with a recovery room, its own 18-space car park and more than 55 staff. The staff page names seven clinicians with their specialities and training institutions, covering operative dentistry, endodontics, paediatric dentistry including nitrous-oxide conscious sedation, preventive dentistry and periodontics, and oral rehabilitation. Services published include surgery and implantology, prosthetics and rehabilitation, orthodontics, paediatric dentistry, aesthetic dentistry, orofacial harmonisation, speech therapy, an in-house digital laboratory and a teaching arm. Opening hours are Monday-Friday 08:00-19:00 and Saturday 08:00-12:00, with a separate out-of-hours emergency number.
The site is mid-relocation: the contact page and the Forbes report give Moisés Bertoni 991 esq. Dr. Weiss (Villa Morra) while the page header and older directory entries still show Avda. Mariscal López 4861. The card uses the contact-page address, and the Google place record confirms it — the listing reads "Margraf Dental Center, Moisés Bertoni, Asunción 001411". The initial data collection could not retrieve that listing: four Google Maps text searches on 2026-09-10 returned an empty record for the clinic's name. The verification pass reached it instead through the CID the clinic embeds in its own contact-page map (0x945da8b97adb1bdf:0x64f26a25782e2511), which resolves to a live place page carrying rating, review count, histogram, hours and reviews. The coordinates on this card now come from that place record; the earlier pair sat on the clinic's former Mariscal López address, about 1.3 km away.

Score Breakdown
Every criterion below is scored from public sources. ✓ verified yes · ✗ verified no / not found · ◐ partial · ? unverified (scores 0, not a negative finding).
Information Transparency
Whether basic facts about the clinic - its team, premises, services, and location - are publicly verifiable.
| ✓ | Has a working website margrafdentalcenter.com serves a full multi-page site with staff, services, blog and contact pages [s1] | 4/4 |
| ✓ | Dentist names listed seven clinicians named with speciality and the institution that awarded it [s2] | 3/3 |
| ✓ | Dentist specializations listed surgery and implantology, prosthetics and rehabilitation, orthodontics, paediatric dentistry, aesthetic dentistry, orofacial harmonisation, speech therapy [s2] [s3] | 2/2 |
| ✓ | Real clinic photos The clinic runs a gallery page showing its own premises and its own equipment, including an air-abrasion unit, a curing light and a surgical kit. [s9] | 2/2 |
| ✓ | Service list published services page listing each treatment area with a detail link [s3] | 3/3 |
| ✓ | Clear contact details address, phone, e-mail, WhatsApp, opening hours and a separate out-of-hours emergency number [s4] | 2/2 |
| ✗ | English website version The site header shows Spanish, Portuguese and English flag icons, but no English version of the page could be reached on 2026-09-11 and the document language stays Spanish. [s1] | 0/2 |
| ✓ | Address and map published contact page publishes the address and embeds a Google Maps frame for the clinic's own place [s4] | 2/2 |
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) as of 2026-09-10 [s8] | 4/6 |
| ◐ | Google review volume as of 2026-09-10 [s8] | 2/3 |
| ✓ | Review recency newest review rendered on the clinic's own Google place page is two months old (read 2026-09-10) [s8] | 3/3 |
| ✗ | Clinic responds to reviews The clinic does not answer reviews. The listing was read twice on 2026-09-11 — eight of its 119 reviews in the reviews panel and five returned by an automated fetch, dated between 29 October 2025 and 7 July 2026 — and no record from either reading carries a reply, including the reviews that complain about waiting times. The listing is claimed by the business, which carries a photograph uploaded through its own Google Business account, so the absence of replies is a choice rather than a technical obstacle. [s8] | 0/2 |
| ✗ | No recurring complaints A repeated complaint is recorded, on two independent dated reviews five months apart that make the same point about waiting far past the booked appointment: a one-star of 27 June 2026 — "el tiempo de espera es un aspecto que deberían mejorar. En reiteradas ocasiones he agendado mi cita para una hora específica y la atención ha comenzado con demoras considerables" — and a three-star — "Buena atención, pero el periodo de espera no baja de 1 hora, no importa el horario que te hayan agendado". Both praise the treatment itself; the first says explicitly that the clinical quality deserves better organisation. A third dated review, a three-star of 14 December 2025 written in German, complains about a related but different thing: being called back seven times for two ceramic fillings that his own dentist in Europe said would take two sittings, with the travel cost and lost time each time, while rating the work itself correct and the practice clean. That is a complaint about the number of visits rather than about the wait inside one, so the count of separate accounts on a single subject stands at two — short of the three a red flag requires here, which is why the pattern is recorded but not flagged. The listing carries 11 one-star reviews out of 119 and no reply on any review read. [s8] | 0/2 |
| ✓ | No suspicious review patterns the histogram 11/1/3/1/103 is a natural spread and review ages run from two to ten months [s8] | 2/2 |
| ✓ | Active Facebook presence facebook.com/ClinicaMargrafdentalcenter linked from the site [s1] | 1/1 |
| ✗ | TripAdvisor presence No TripAdvisor listing found via its search for "Margraf Dental Asuncion" and "Margraf" (2026-10-02); the clinic's site does not link to TripAdvisor. [margraf-dental-health-center-asuncion-deepen] [margraf-dental-health-center-asuncion-deepen-2] | 0/0.5 |

Change History
| Date | Change |
|---|---|
| 2026-10-02 | Presence re-checked on 2026-10-02: no TripAdvisor listing (two searches of its index and the clinic's site). |
| 2026-10-02 | offersSedation: true -> false. The clinic offers conscious sedation only (nitrous oxide or oral sedatives), not general anaesthesia or deep sedation. |
| 2026-10-01 | Presence on other review platforms re-checked: no profile on WhatClinic, Dental Departures or Bookimed, so this criterion is now no. |
| 2026-09-11 | The recurring complaint about waiting past the booked appointment was re-read and dated to the day, and a third critical review was found that had not been read before: a German-language three-star of 14 December 2025 objecting to seven visits for two fillings. It is recorded in the note but counted separately, because it concerns the number of appointments rather than the wait within one — so the number of separate accounts making the same complaint stays at two, and no red flag is placed. Whether the clinic answers reviews was confirmed by a second, independent reading of the listing: no reply on any record, on a listing the business does control. |
| 2026-09-10 | Adversarial verification: the Google place record that four the initial data collection text searches had missed was reached through the CID in the clinic's own embedded map — rating 4.5 from 119 reviews, histogram, hours and reviews recorded, coordinates corrected from the clinic's former address to the place record, and a recurring complaint about waiting times identified. |
| 2026-09-10 | Card created from the clinic's own site (home, staff, services, contact) and a Forbes Paraguay report; no Google place record could be retrieved in four searches, so the Google fields are unverified and the coordinates come from the clinic's own embedded map. |
