What does "recommended" mean here, and what are the selection criteria?
Only disclosed facts: 1) Clinics with at least one Periodontics specialist registered with HIRA (Health Insurance Review & Assessment Service, the South Korean government agency for healthcare data) 2) The 5 clinics meeting all criteria above, shown director-verified clinics first, then longest-operating (by HIRA-registered opening date) (director-verified clinics appear first because their information was provided and confirmed directly; this is not paid placement) 3) Public HIRA data does not list individual procedures, so this list uses the related dental specialty as the criterion. Ask each clinic whether it offers this treatment. This is an informational shortlist that narrows options by objective criteria, not an evaluation or guarantee of any clinic's treatment quality or outcomes.
Is this list an advertisement?
No. No clinic has paid to appear on this list, and payment cannot buy inclusion or ranking. The list is compiled from HIRA public data using the criteria above, shown director-verified clinics first, then longest-operating (by HIRA-registered opening date). Director-verified clinics appear first because their information was confirmed directly, verification is a free process open to every clinic, unrelated to partnership or payment. No ratings or review data are used.
How does a clinic get "director-verified"? Does it cost anything?
It is free. A clinic director submits information through the "Our clinic" page on DentStat; the site operator checks the submission against HIRA registration data before publishing, and promotional or evaluative wording is not accepted so only facts are published. The process is open to every clinic regardless of partnership. Where HIRA registration (specialist count, hours) lags reality, director-verified data is shown alongside with its own source label.
