Anesthésie générale & sédation profonde

Indique si la clinique documente des soins sous anesthésie générale ou sédation profonde / crépusculaire — la « dentisterie sous sommeil », où le patient dort et n'a conscience de rien (il ne sent, ne voit et n'entend pas l'intervention). La sédation consciente ordinaire, où le patient reste éveillé et réactif, ne compte pas ici. Information indicative, sans effet sur le score de transparence.

  • ✗ Anesthésie générale / sédation profonde (dentisterie sous sommeil) — Aucune anesthésie générale ni sédation profonde documentée The clinic publishes what it calls semi-conscious sedation, and the Ontario register, read on 2026-09-07, records the practice sedation and anaesthesia facility permit as Type A with facility modality "Parenteral Conscious Sedation" and the named dentist authorisation as "Minimal Nitrous Oxide/Oral Sedation". Methodology 1.4.0 counts only general anaesthesia or deep intravenous / twilight sedation, so no qualifying level is documented. [s4] [regd1]

Transparence de l'information

20 / 20

Indique si les faits de base concernant la clinique — son équipe, ses locaux, ses services et sa localisation — sont vérifiables publiquement.

✓ Dispose d'un site web fonctionnel Live on 2026-09-07: HTTP 200 with the practice content in the body. [s1] 4/4
✓ Noms des dentistes publiés The team page names Dr. Karen MacDonald DDS, Dr. Sassi DDS and Dr. Jennifer Bayne DDS, alongside the named hygienists, assistants and administrators. [s2] 3/3
✓ Spécialisations des dentistes indiquées Each named dentist carries their dental degree on the team page, and the practice states the clinical areas it covers at this one location. [s2] 2/2
✓ Photos réelles de la clinique Newly settled in a browser on 2026-09-08 — the criterion had been null because the delivered HTML of the clinic's team page carries no staff photographs. The place page's lead owner photograph is the practice's own team: eight members of staff in white coats over the clinic's navy uniform, standing in its own reception with the practice's name lettered on the wall behind them. Team and premises together, so the criterion is met from a channel the clinic controls. [gmpb] 2/2
✓ Liste des services publiée Service menu covering family, cosmetic, hygiene, fillings, implants, veneers, emergency, paediatric, periodontics, aligners, whitening, sports and wisdom-teeth care. [s1] 3/3
✓ Coordonnées claires Address, phone 613-729-3338, fax, e-mail info@prestondentalcentre.com and full opening hours are published on the contact page and the phone matches the Google place record. [s3] 2/2
✓ Version anglaise du site web The site is published in English. [s1] 2/2
✓ Adresse et carte publiées Full street address with suite and postcode plus an embedded map. [s3] 2/2

Réputation et avis

15 / 20

Signaux d'avis publics. La note Google est ajustée avec un a priori bayésien (note 4,0, poids 25) afin qu'un 5,0 issu d'une poignée d'avis ne surclasse pas un 4,8 issu de centaines d'avis.

◐ Note Google (ajustement bayésien) Read live on the place page in a browser on 2026-09-08. Unchanged from the automated reading of 2026-09-07. The star histogram — 80 five-star, 0 four-star, 0 three-star, 0 two-star and 7 one-star — sums to 87, matching the 87 in the place-page header exactly, and its weighted mean 4.678 reproduces the published 4.7. [gmp1] [gmpb] 5/6
◐ Volume d'avis Google Read live on 2026-09-08 from the place-page header, and the star histogram sums to the same figure. The card carried no count before this pass: the automated map method used in the initial data collection returns the rating but never the review count on this listing, which is why it was queued for a manual browser check. [gmpb] 1.5/3
✓ Fraîcheur des avis Newest Google review is dated 2026-09-15 (listing read 2026-09-25). [preston-dental-centre-ottawa-gbp-2026-09-25] 3/3
? La clinique répond aux avis 6 reviews from the last 24 months were read on the Google listing, none with an owner reply, too few to say the clinic does not answer reviews (read 2026-10-05). 0/2
✓ Absence de plaintes récurrentes One critical account is visible, a one-star six months old saying that two different receptionists asked the reviewer questions she describes as ableist and that she had expected staff working with the public to have had sensitivity training; the rest is behind Google's truncation. It is recorded as an unproven patient account and without naming anyone. It stands alone in the visible sample, so no theme repeats and the criterion is false. The one- and two-star mass is 7 of 87 = 8.0 %, and the other six accounts are not surfaced by relevance ordering. The count is read here for the first time, so a 4.7 with no disclosed base now rests on a measured 87. Sample: the eight reviews Google Maps renders on the place page in its own relevance order; a newest-first list was not available, so a review more recent than the newest one visible may exist. [gmpb] 2/2
✓ Absence de schémas d'avis suspects Judged on the histogram shape, the spread of dates, the variety of reviewers and the wording, on 2026-09-08. The distribution is strictly two-valued — 80 five-star and 7 one-star, with nothing at four, three or two — and that is disclosed rather than explained away. Against a manipulation reading: the visible dates run from five months to ten years, the accounts describe different treatments at very different lengths, several identify their writers as patients of five years or more, and the owner answers none of the reviews at all, which is the opposite of a curated record. [gmpb] 2/2
✓ Présence Facebook active The practice Facebook page was opened on 2026-09-07 and carries the name Preston Dental Centre - Ottawa. The clinic site itself does not link it. [fb1] 1/1
✗ Présence sur TripAdvisor TripAdvisor's own search index was queried in a real browser on 2026-09-10, under the clinic name and again with the city appended; it carries no listing for this practice. [preston-dental-centre-ottawa-deepen] 0/0.5
✓ Autres plateformes d'avis Has its own WhatClinic profile at the clinic's address with staff biographies, photos and opening hours; no patient reviews there yet. [preston-dental-centre-ottawa-deepen-4] 0.5/0.5

Infrastructure médicale

11 / 15

L'éventail des équipements et des services documentés publiquement. Cela mesure la disponibilité documentée, et non la qualité clinique.

✓ Radiographie sur place The clinic states on its family-dentistry page that its own dental x-ray techniques and equipment are designed to keep patient radiation exposure as low as possible (read 2026-09-10). [preston-dental-centre-ottawa-deepen-3] 2/2
✗ CBCT (imagerie 3D) The Ontario register publishes a CT Scanner Facility Permit flag for every practice address on a dentist record. Read on 2026-09-07, the record for this practice (343 Preston St #110) carries "CT Scanner Facility Permit: No". A dental cone-beam scanner in Ontario requires that permit, so this is a checked negative from the statutory regulator rather than an unchecked field. [regd1] 0/2
✓ Implantologie Dental implants service page. [s1] 2/2
✓ Orthodontie Clear-aligner service page. [s1] 2/2
✓ Chirurgie orale Wisdom teeth removal and periodontics pages. [s1] 2/2
✓ Dentisterie pédiatrique Paediatric dentistry page. [s1] 1.5/1.5
✓ Soins d'urgence Emergency dentistry page. [s1] 1.5/1.5
✗ Accueil de patients internationaux The clinic addresses a domestic Canadian patient base and documents no international-patient provision. [s1] [s3] 0/2

Communication et service

3.5 / 10

La facilité avec laquelle on peut contacter la clinique, obtenir des réponses et prendre rendez-vous — en particulier pour les personnes ne parlant pas la langue locale.

✗ WhatsApp / LINE disponible No WhatsApp or LINE contact is published. [s3] 0/2
? Rapidité de réponse 0/1.5
✓ Anglais parlé The practice operates and publishes in English. [s1] 2.5/2.5
✗ Consultation préalable possible An appointment-request form exists, but the clinic does not offer a preliminary estimate through it. [s3] 0/1.5
✓ Explications claires des services Each treatment has its own explanatory page. [s1] 1/1
✗ Horaires d'ouverture pratiques Revised on the clinic's own Google Business Profile, read in a browser on 2026-09-08, which publishes the full week: Monday to Thursday 08:00–17:00, Friday 07:30–14:30, **Saturday and Sunday closed**. The value was previously true and rested on the site's line that Saturday appointments are offered. The methodology's rule is applied uniformly here as elsewhere: an offer of appointments «on request» or «by arrangement» is not a published weekend opening, and where a clinic's own two channels disagree the more favourable one is not credited. No weekday close reaches 19:00 on either channel, so the criterion becomes a verified false. Both readings are on the record. [s3] [gmpb] 0/1.5

Visibilité IA et recherche

Indique si la clinique est repérable lorsque les patients effectuent des recherches — y compris via les assistants IA. Vérifié avec des requêtes fixes : "best dentist Canada", "English speaking dentist Canada", "dental implants Canada", "emergency dentist Canada", "Canada dental clinic for expats".

✗ Mentionnée pour : best dentist Canada Canonical visibility query best dentist Ottawa, run in the AI-visibility pass on 2026-09-07: the clinic own domain does not appear in the recorded result set. The Ottawa result set of this query is partly occupied by same-name results from Ottawa, Illinois; five of the nine recorded results are unambiguously Ottawa, Ontario, which is enough to read the clinic absence or presence.

regd1https://www.rcdso.org/find-a-dentist/search-results/dentist?id=11702The Ontario register publishes a CT Scanner Facility Permit flag for every practice address on a dentist record. Read on 2026-09-07, the record for this practice (343 Preston St #110) carries "CT Scanner Facility Permit: No". A dental cone-beam scanner in Ontario requires that permit, so this is a checked negative from the statutory regulator rather than an unchecked field. (The supports text of this source was missing from the card; it was written on 2026-09-10 from the finding the card itself records for it, and the page was not re-read on that date.)2026-09-07
gmpbhttps://www.google.com/maps/place/x/@45.4020316,-75.7101172,17z/dat…The clinic’s Google Maps place page, opened in a real browser on 2026-09-08. The Reviews tab (this URL) gives the headline rating, the review-count header, the five star-histogram buckets read whole from their accessibility labels, and the eight most-relevant reviews with their star values, dates, text and owner replies; the sibling Overview URL https://www.google.com/maps/place/x/@45.4020316,-75.7101172,17z/data=!4m5!3m4!1s0x4cce04344c7929e3:0x68c207bf01e1fd80!8m2!3d45.4020316!4d-75.7101172?hl=en gives the listing name, address, telephone, website, business category, the full published opening week and the lead owner photograph. The listing opens as «Preston Dental Centre», category Dentist, at 343 Preston Street, Suite 110, in Preston Square, Ottawa ON · +1 613-729-3338 · prestondentalcentre.com — the identifiers the card itself carries, so the place identifier resolves to this practice and not to a neighbour.2026-09-08
preston-dental-centre-ottawa-deepenhttps://www.tripadvisor.ca/TypeAheadJson?action=API&query=Preston+D…TripAdvisor's own type-ahead search endpoint, the one its search box calls, opened directly in a real browser on 2026-09-10. Queried under the clinic name alone and again with the city appended, it returns no listing for this practice; the query broadens to dental-clinic listings in other countries instead. A control query for an existing dental-clinic listing (Old Igarashi Dental Clinic, Shizuoka) returns that listing at rank 1, so the method does surface dental clinics when they are in the index. The /Search results page itself never resolves past its loading spinner for a signed-out session, which is why the search endpoint is cited.2026-09-10

Historique des modifications

DateModification
2026-10-05Reputation check 2026-10-05 on the clinic's Google listing (16 reviews read): nothing settled; owner replies to reviews left unassessed.
2026-10-02Other review platforms checked on 2026-10-02: WhatClinic profile at the clinic's address.
2026-09-29Corrected 2026-09-29: clinic responds to reviews now unverified: only 8 reviews were checked for owner replies; review recency within 3 months (newest review dated 2026-09-15).
2026-09-10Re-checked on 2026-09-10: the identification question on "Dr. Sassi" was re-tested against the Ontario register, and the single Ontario record under that surname was read in full in a real browser. It still publishes no practice address, and an address search of the register for 343 Preston Street still returns only the two other dentists on this card, so the record still cannot be tied to this practice. The gate decision of 2026-09-09 stands: no registration number is attributed to this dentist and nothing from that individual record is reported on this card. The licence entry remains "not found in the public register (checked 2026-09-07)".
2026-09-10Checked by hand in a browser on 2026-09-10: TripAdvisor carries no listing; the Yellow Pages listing answers a CloudFront 403 to a real browser too, so onOtherPlatforms stays null; hasXray moves null to true after the clinic site, previously inaccessible, was read in a browser and found to state that its own x-ray equipment is chosen to minimise patient dose.
2026-09-09Editorial-gate decision, option (b). The RCDSO registration number previously printed against "Dr. Sassi" is withdrawn to licenseNotFound: the identification rested only on the surname being unique in Ontario, with no address corroboration on either side, and the register record carries a published 2017 regulatory outcome. Publishing the number while withholding what the same record says would be the least defensible option; attaching a regulatory finding to a person on an uncorroborated surname match would be worse. The dentist stays in the roster under the name the clinic publishes, and the register record is not cited about the individual.
2026-09-08Checked by hand in a browser: the clinic’s Google Maps place page was opened in a real browser and read on both its Reviews and Overview tabs. Recorded from it: the rating re-verified against the star histogram, the review count (previously unknown — the automated map method never returned it), the histogram itself (80/0/0/0/7 = 87, weighted mean 4.678), review recency, the owner-reply state, the complaint reading and the manipulation reading from the eight most-relevant reviews, the lead owner photograph and the full published opening week. Fields this pass did not measure are untouched.
2026-09-07Adversarial verification (no browser): all four mandatory sweeps run on the card; every cited URL re-fetched for liveness; the Google rating and coordinates re-read independently from the live place record and confirmed; the licensing block re-run against the province statutory register; TripAdvisor probed directly and found unreadable to an automated client. On this card, the Ontario register record for the practice was opened and cited directly: it settles cone-beam CT as a checked negative and the sedation level as a checked negative, and it adds a Type A sedation facility permit to the summary. The Sassi identification was re-run and its caveat, including what the register publishes on that record, was written down. The clinic licence citation now names the Ontario regulator.
2026-09-07Initial data collection (no browser): clinic site read page by page for services, named staff, contacts, hours and fees; the live Google place record read through the automated map endpoint for rating, category and pin coordinates; all three named dentists matched in the Royal College of Dental Surgeons of Ontario public register, two of them by the suite address and phone printed on the record; a name query used for indexing quality and independent listings; the four canonical visibility queries taken from the AI-visibility pass, with the Ottawa, Illinois contamination of one of them recorded. Premises photography, review count, recency and the complaint and manipulation readings are left null and queued for a manual browser check.
