Historique des modifications
| Date | Modification |
|---|---|
| 2026-09-18 | Re-read on 2026-09-18 together with a neighbouring clinic's re-read: the clinic's English and Thai sites, the Google listing and reviews of the Ratchadaphisek head office, the Ministry of Public Health register of private healthcare facilities and the Dental Council of Thailand register. The head office holds operating licence 10103002557 (valid until 2033), and the fifteen dentists named on this page hold a licence in the Dental Council register. The fee list gives standing prices for check-ups (free), X-rays, cleaning, fillings, crowns and root canal treatment; implant fees are shown only as promotions. The site also describes 3D CT scanning, children's dentistry and same-day appointments by phone. Four Google reviewers state that the clinic offered a discount or a promotional price in return for a review, several low-rated reviews describe long waits or an appointment not kept, and the clinic does not reply to Google reviews. Google: 5.0 from 2,834 reviews. |
| 2026-09-10 | The clinic licence found on 2026-08-26 was added to this page: the Ministry of Public Health register lists 'Sun Thantakam Samai Siknechoe Ratchadaphisek' (Smile Signature Dental Center Ratchadaphisek) at the clinic's address, 257/26-27 Ratchadaphisek Road, Din Daeng, with operating licence 10103002557, valid to 31 December 2033; the earlier "not published" entry is withdrawn. |
| 2026-08-25 | Licence check 2026-08-25: the Ministry of Public Health register of private healthcare facilities returned no match under the two spellings tried, so the clinic licence was shown as not published (corrected: licence 10103002557, found on 2026-08-26). |
| 2026-08-25 | Recorded sedation / general anaesthesia availability (informational): documented as available. Own site states clinic partners with BIDH Dental Hospital to offer 'total sleep dentistry' for anxious patients. |
| 2026-08-25 | Re-verification 2026-08-25: confirmed website/address unchanged; phone verified today as +66 2 693 6933 via both the site and Maps (stored +66 91 002 2288 was not found on either source and appears outdated). Google rating jumped to 5.0 (2,826 reviews) from 4.8/683 on the head-office Ratchada listing. Clinic's own site confirms 'total sleep dentistry' via partner BIDH. Captured Maps URL and geo. |
| 2026-07-08 | Added Licensing & Credentials (methodology v1.1): clinic licence and dentists/their licence numbers. |
| 2026-07-03 | Initial data collection. |
