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 The published services and facility description document no general anaesthesia or deep sedation. [s1]
Summary

It publishes digital dental X-ray and radiovisiography, dedicated paediatric zones, an implant service and a bilingual site, and holds 256 Google reviews at 4.7. Its two published opening lines contradict each other, and no prices or registration numbers are published.

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
20 / 20
Whether basic facts about the clinic - its team, premises, services, and location - are publicly verifiable.
| ✓ | Has a working website Read on 2026-09-10: a current site that redirects to its own English locale and carries dentist profiles, a facility description, an FAQ and testimonials — real body content, not a placeholder. [s1] | 4/4 |
| ✓ | Dentist names listed The clinic names its dentists on its own doctors page, re-read on 2026-09-11: four of them now, each with qualifications, years in practice and hospital post, and each with a working individual profile page. The two profile links that had gone dead are live again. [s1] [s5] | 3/3 |
| ✓ | Dentist specializations listed BDS, MS in oral and maxillofacial surgery and Fellow of the International College of Dentists, associate professor at Khulna Medical College for the first; BDS, DDS and F.I.C.D., associate professor at Sheikh Abu Naser Specialized Hospital for the second. Published on the clinic's own front page and its doctors page, both re-read on 2026-09-10. [s1] [s2] | 2/2 |
| ✓ | Real clinic photos The listing's photographs were downloaded at full size and looked at on 2026-09-11. They show these premises: the reception, a curved desk under the practice's own "Cash & Counselling Corner" lettering with a paediatric bay behind it, curtained off and painted with an undersea mural; a treatment room with the chair, an X-ray unit on its wall arm and a laptop showing a radiograph; and a wall hung with some twenty-five framed degrees and certificates. Genuine premises, not stock imagery. [gm2] | 2/2 |
| ✓ | Service list published The clinic publishes its treatment range on its own front page and a services index of its own — dental implants, orthodontic treatment, digital dental X-ray and radiovisiography and dedicated paediatric zones — and its appointment form names fifteen treatments including maxillofacial surgery, extractions and fracture management. [s1] [s3] [s4] | 3/3 |
| ✓ | Clear contact details A telephone number is published on the clinic's own site and matches the Google listing. [s1] | 2/2 |
| ✓ | English website version The site serves an explicit English locale at /en/ and redirects to it, so the practice publishes in English as well as Bengali. [s1] | 2/2 |
| ✓ | Address and map published Refuted on re-reading the source on 2026-09-10: the clinic publishes its street address in four places on its own site — the header bar, the "Visit Our Clinic" block, the footer and its own schema.org PostalAddress — as "PARUPALLI, 20 Wahab Avenue, East Side of Iqbalnagar Girl's School, Khulna", and links a Google Maps search on it. The first pass recorded it as unestablished. [s1] [s4] | 2/2 |
Price Transparency
0 / 15
Whether patients can estimate costs before visiting. Published price ranges count; exact prices are not required.
| ✗ | Prices or price ranges published No price list or ranges anywhere on the clinic's own site. [s1] | 0/3 |
| ✗ | Cleaning price listed No cleaning or scaling price is published. [s1] | 0/2 |
| ✗ | Filling price listed No filling price is published. [s1] | 0/2 |
| ✗ | Crown price listed No crown price is published. [s1] | 0/2 |
| ✗ | Implant price listed Implants are a published service with no price. [s1] | 0/2 |
| ✗ | Consultation price listed No consultation fee is published. [s1] | 0/2 |
| ✗ | X-ray / imaging price listed Digital X-ray and radiovisiography are published as facilities with no price. [s1] | 0/2 |
Reputation & Reviews
15.5 / 20
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) Read from the live Google Maps place record on 2026-09-10 (automated tile read, hl=en), confirmed by a second read the same day with a different query form. [gm1] | 5/6 |
| ◐ | Google review volume 256 reviews, re-read from the listing's own place record on 2026-09-11; the star histogram (1★=11, 2★=3, 3★=3, 4★=7, 5★=232) sums to exactly that figure, one more than the 255 recorded a day earlier as the base grew. The clinic's own embedded widget shows 247; the listing is what counts. [gm1] [gm2] | 2.5/3 |
| ✓ | Review recency Newest Google review is dated 2026-09-21 (listing read 2026-09-25). [decent-specialized-dental-care-khulna-gbp-2026-09-25] | 3/3 |
| ✗ | Clinic responds to reviews None of the 11 reviews read from the last 24 months (2025-04-03 to 2026-10-01) carries an owner reply on the Google listing (read 2026-10-05). [decent-specialized-dental-care-khulna-r6rep] | 0/2 |
| ✓ | No recurring complaints Of 267 Google reviews, 16 are one- or two-star (6.0 %); the lowest-rated read (2021-2025) raise different matters (a root canal outcome, appointment waits, damage during scaling, doctor manner), so no complaint recurs (read 2026-10-05). [decent-specialized-dental-care-khulna-r6rep] | 2/2 |
| ✓ | No suspicious review patterns Star histogram read on 2026-09-11: 1★=11, 2★=3, 3★=3, 4★=7, 5★=232 across 256 reviews, averaging 4.70. Every bucket is populated, including eleven one-star ratings — a base carrying that much dissent has not been bought. The five readable reviews spread over two and a half years and one of their authors is a Local Guide. No burst and no repeated wording. [gm2] | 2/2 |
| ✓ | Active Facebook presence Found on 2026-09-11 by searching Facebook for pages under the clinic's name, after neither its website nor its Google listing turned out to link one. The page carries the clinic's name exactly as the Google listing spells it, comma and all, and has about 1,500 followers. Its own description claims five digital dental units, an operating theatre and a post-operative room; that is the clinic's own claim about itself and is recorded as such, not as a verified fact. [fb1] | 1/1 |
| ✗ | TripAdvisor presence No TripAdvisor listing found via its search for "Decent Specialized Dental Care Khulna" and "Decent Specialized"; the clinic's site does not link to TripAdvisor (checked 2026-10-05). [decent-specialized-dental-care-khulna-tripadvisor] [decent-specialized-dental-care-khulna-tripadvisor-2] | 0/0.5 |
| ✗ | Other review platforms No profile of the clinic on WhatClinic, Healtha, Dental Departures, Bookimed or Trustpilot (Healtha has only an unclaimed automatic listing without reviews) (checked 2026-10-02).

Medical Infrastructure
9.5 / 15
The range of publicly documented equipment and services. This measures documented availability, not clinical quality.
| ✓ | On-site X-ray The clinic publishes digital dental X-ray and radiovisiography as part of its own facility description. [s1] | 2/2 |
| ✗ | CBCT (3D imaging) Only digital intraoral radiography is claimed; no cone-beam CT. [s1] | 0/2 |
| ✓ | Implantology Dental implants are a published service line. [s1] | 2/2 |
| ✓ | Orthodontics Orthodontic treatment is published, and one of the clinic's own testimonials is from a braces patient. [s1] | 2/2 |
| ✓ | Oral surgery The clinic is led by an associate professor holding an MS in oral and maxillofacial surgery, published as its specialist. [s1] | 2/2 |
| ✓ | Pediatric dentistry The clinic publishes dedicated zones for paediatric care as part of its facility. [s1] | 1.5/1.5 |
| ? | Emergency care No emergency or same-day service is documented on the clinic's own site. Left unset rather than recorded as a denial. [s1] | 0/1.5 |
| ? | Works with international patients The clinic republishes a testimonial from a patient living in Canada who returns for check-ups, but publishes no international-patient service, insurance handling or language support. Left unset. [s1] | 0/2 |
Communication & Service
6.5 / 10
How easy it is to contact the clinic, get answers, and book - especially for international patients.
| ✗ | WhatsApp / LINE available The site publishes a voice number only; no WhatsApp or messenger link appears in its markup. [s1] | 0/2 |
| ? | Response speed | 0/1.5 |
| ✓ | English spoken The clinic publishes an English version of its own site with its dentist profiles and FAQ. [s1] | 2.5/2.5 |
| ✓ | Pre-visit consultation possible The clinic publishes a full appointment form on its own contact page — name, e-mail, telephone, date, a time-slot picker running from 09:00 to 21:00 and a treatment picker of fifteen named services — with a stated 24-hour confirmation. [s4] | 1.5/1.5 |
| ✓ | Clear service explanations The clinic explains its facility, its specialists and its history in plain English, with an FAQ answering how long it has been in service. [s1] | 1/1 |
| ✓ | Convenient opening hours Confirmed on 2026-09-11, and the listing settles the contradiction on the website. The clinic's own pages state the closing time as 21:00 four times over and agree, but give two different opening times — one line reads "4 AM" and another "5 PM". The practice's own Google Business Profile publishes Saturday to Thursday 15:00–21:00 with Friday closed, which matches the 21:00 close and puts the opening at 15:00, so neither published opening line is right. Evening appointments are available six days a week. [s1] [s4] [gm2] | 1.5/1.5 |
AI & Search Visibility
6 / 10
Whether the clinic is discoverable when patients search - including via AI assistants. Checked with fixed queries: "best dentist Bangladesh", "English speaking dentist Bangladesh", "dental implants Bangladesh", "emergency dentist Bangladesh", "Bangladesh dental clinic for expats".
| ✓ | Mentioned for: best dentist Bangladesh The canonical city query was run in the AI-visibility pass on 2026-09-10 (web search) and the clinic's own front page appears at rank 3. [bsq1] | 1/1 |
| ✗ | Mentioned for: English speaking dentist Bangladesh The canonical query was run on 2026-09-10; the clinic does not appear. [bsq2] | 0/1 |
| ✓ | Mentioned for: dental implants Bangladesh The clinic's own front page appears at rank 3 and a dentist profile page on its own domain at rank 9 for this canonical query on 2026-09-10. [bsq3] | 1/1 |
| ✗ | Mentioned for: emergency dentist Bangladesh The canonical query was run on 2026-09-10; the clinic does not appear, consistently with publishing no emergency service. [bsq4] | 0/1 |
| ✗ | Mentioned for: Bangladesh dental clinic for expats The canonical query was run on 2026-09-10; the clinic does not appear. [bsq5] | 0/1 |
| ✓ | Structured data on website The site emits schema.org JSON-LD with a Dentist entity, a PostalAddress and an OpeningHoursSpecification — genuine practice-level markup, and the only Khulna card that carries it. [s1] | 1.5/1.5 |
| ◐ | Google indexing quality Re-run on 2026-09-10 after the first-pass instance returned nothing: the name-and-city search does return the clinic's own front page first, but only two of the first ten results are on its own domain and one of those two now 404s. The rest of the page is its Facebook profile, YouTube and third-party doctor directories. [giq1] | 1/2 |
| ✓ | Dedicated service pages Re-sourced on 2026-09-10 after the page cited in the first pass turned out to 404. The clinic keeps separate treatment URLs on its own domain — /en/services/dental-implants, /root-canal-treatment, /smile-design, /teeth-whitening and /crown-bridge — alongside a doctors page and a services index. [s2] [s3] | 1.5/1.5 |

| Date | Change |
|---|---|
| 2026-10-05 | TripAdvisor presence checked on 2026-10-05: no listing found for this clinic. |
| 2026-10-02 | Reputation check 2026-10-05 on the clinic's Google listing (15 reviews read): recurring complaints no, owner replies to reviews no. |
| 2026-10-02 | Presence on review sites re-read on 2026-10-02: no profile on the review platforms checked. |
| 2026-09-29 | Corrected 2026-09-29: clinic responds to reviews now unverified: only 5 reviews were checked for owner replies; review recency within 3 months (newest review dated 2026-09-21). |
| 2026-09-11 | A Facebook page was found for the clinic, which neither its website nor its Google listing links. It carries the clinic's name exactly as the listing spells it and has about 1,500 followers, so the social-presence field could be recorded for the first time. |
| 2026-09-11 | Reputational check against the listing's own place record, which returned the star histogram, five reviews with exact dates, the published opening week and the listing's photographs. The published review count moved from 255 to 256 as the base grew, matching the histogram exactly, and the summary was brought into line. Review recency, owner replies and review patterns were settled for the first time; repeated complaints stay unset with the proportion disclosed, because none of the fourteen critical reviews is readable. The published opening week was read from the Business Profile and settles the contradiction between the website's two opening lines: neither is right, the listing gives 15:00. The clinic's doctors page was re-read: the individual profile links that had gone dead are working again, and the roster now names four dentists rather than two — Dr. Nigar Sultana (Shampa) and Dr. Kazi Maria Haque (Seeme) have been added with the qualifications the clinic publishes for them. The photographs were downloaded and examined and show the reception, a treatment room and the certificate wall. |
| 2026-09-10 | Adversarial verification. The street address was refuted as unestablished: the clinic publishes "PARUPALLI, 20 Wahab Avenue, East Side of Iqbalnagar Girl's School, Khulna" in its header, its "Visit Our Clinic" block, its footer and its own structured data, and the card address was corrected from the bare city name. The opening week was recorded too — the clinic states it four times and all four agree on a Saturday-to-Thursday evening week closing at 21:00, though the opening time is stated three different ways, which is recorded as a red flag rather than hidden. The dentist profile page cited in the first pass now 404s and was replaced with the clinic's live doctors, services and contact pages, and the name search was re-run. The notes recording the state of the register were taken out of the published doctors table, where they had made each licence cell read "not published" instead of "not verified" — a denial the data never made. |
| 2026-09-10 | Initial data collection: the clinic's own English front page and a dentist profile page were read and the Google Maps place record was read directly twice; the five canonical city queries came from the AI-visibility pass. The street address, the social presence, the booking route and the opening week were left unset with reasons, the clinic's own two opening statements contradicting each other; review-side fields queued for a manual browser check. Both licence layers unset for register reasons. |
