General Anaesthesia & Deep Sedation

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
Single-site dental practice in Asunción's Villa Aurelia area, trading since 1999 and led by Dr. Gastón Trossero. The site publishes a full treatment taxonomy across implantology, endodontics, prosthetics, aesthetic dentistry, oral surgery, periodontics, oral rehabilitation, gerodontology, orthodontics and general dentistry, each with its own page, plus an English-language version of the site. Diagnostics listed on site include panoramic radiography, intraoral scanning and cone-beam CT, with an in-house laboratory. Appointments run Monday to Wednesday 14:00-20:00 and Thursday to Friday 09:00-15:00; booking is by WhatsApp. The site footer states a Ministry of Public Health registration number (2153); that number could not be checked because the ministry register was unreachable on the research date.
Google Business listing is titled 'Dr. Gaston Trossero - Odontología Avanzada'; the clinic's own site and its structured data use 'Clínica Gastón Trossero' / 'Clínica Odontológica Dr. Gastón Trossero', so the card carries the clinic's own name. Address and phone match between the site and the Google place record. The site's MedicalOrganization structured data declares availableLanguage 'English'.

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 gastontrossero.com returns a full site with treatment, blog and contact content [s1] | 4/4 |
| ✓ | Dentist names listed the practice principal Dr. Gastón Trossero is named throughout; no separate roster of associate dentists is published [s1] | 3/3 |
| ✓ | Dentist specializations listed implantology, endodontics, prosthetics, aesthetic dentistry, oral surgery, periodontics, oral rehabilitation, gerodontology, orthodontics, general dentistry [s1] | 2/2 |
| ✓ | Real clinic photos The clinic publishes photographs of its own premises and staff on its website: an exterior view of the building and a picture of the team, both stored under file names naming the clinic. Not stock imagery. [s1] | 2/2 |
| ✓ | Service list published 26 individual treatment pages grouped in ten specialities [s1] | 3/3 |
| ✓ | Clear contact details WhatsApp number, street address and opening hours published on the site; Facebook and Instagram linked [s1] | 2/2 |

| ✓ | Address and map published full street address with cross-street published in the site footer; matches the Google place record [s1] [s3] | 2/2 |
Price Transparency
Whether patients can estimate costs before visiting. Published price ranges count; exact prices are not required.
| ✗ | Prices or price ranges published the FAQ states that a budget is quoted only after an in-person evaluation; no price list or ranges anywhere on the site [s1] | 0/3 |
| ✗ | Cleaning price listed [s1] | 0/2 |
| ✗ | Filling price listed [s1] | 0/2 |
| ✗ | Crown price listed [s1] | 0/2 |
| ✗ | Implant price listed [s1] | 0/2 |
| ✗ | Consultation price listed [s1] | 0/2 |

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 [s3] | 6/6 |
| ◐ | Google review volume as of 2026-09-10 [s3] | 2/3 |
| ✓ | Review recency newest review rendered on the clinic's own Google place page is two months old (read 2026-09-10) [s6] | 3/3 |
| ✓ | Clinic responds to reviews The practice answers reviews, and answers them individually. The listing was read twice on 2026-09-11: six of the nine reviews in the reviews panel carried a signed reply, and an automated fetch of the same listing returned eight reviews of which all eight carry a dated reply from the practice, several addressing the reviewer by name. The eight are dated between 19 July 2023 and 23 June 2026, so the practice has been answering consistently rather than in one sitting. [s6] | 2/2 |
| ✓ | No recurring complaints no complaint appears in the reviews shown and the star histogram carries no one-star or two-star entries (0/0/2/0/158 across 160 reviews) [s6] | 2/2 |
| ✓ | No suspicious review patterns the 160 reviews spread across three years with two three-star entries, individually written replies and no dated cluster [s6] | 2/2 |
| ✓ | Active Facebook presence facebook.com/dr.gastontrossero linked from the site and listed in its structured data [s1] | 1/1 |
| ✗ | TripAdvisor presence No TripAdvisor listing found via its search for "Gaston Trossero Asuncion" and "Trossero" (2026-10-02); the clinic's site does not link to TripAdvisor. [clinica-gaston-trossero-asuncion-deepen] [clinica-gaston-trossero-asuncion-deepen-2] | 0/0.5 |
| ✗ | Other review platforms No profile found on WhatClinic, Dental Departures, Bookimed or Trustpilot (checked 2026-10-01).
