Data methodology
DentStat is a data site that processes public data to present the current state of dental clinics across South Korea based on facts. Operated by Osamil Inc..
Data sources
- HIRA hospital information service: institution name, location, coordinates, opening date, number of practitioners (type codes 41 dental hospital, 51 dental clinic).
- HIRA detailed institution information service: hours, reception hours, departments, transport, equipment, special care (TMJ, dental care for people with disabilities, etc.) and facility information.
- HIRA non-covered treatment fee information: the source of regional price aggregates by treatment (KOGL Type 1, attribution required).
- Korea National Railway urban rail station data: used to calculate station proximity (station coordinates).
Current data as of October 9, 2026.
Freshness and updates
- Every day HIRA hospital information is rechecked automatically: newly opened clinics are added, and institutions that can no longer be found (closed, relocated, etc.) are removed from lists and statistics.
- Last sync: October 9, 2026 (basis for openings and closures).
- Detailed information such as hours, departments, transport and equipment is based on the March 31, 2026 snapshot.
Aggregation
- Regional statistics count only institutions not confirmed as closed in that district.
- Specialist counts use the dental specialist value (detySdrCnt) provided by HIRA as is.
- Station distance is the straight-line distance between the station and clinic coordinates. Walking time is an estimate: straight-line distance × a detour factor of 1.3, at about 4 km/h.
Non-covered price statistics
- The source is HIRA non-covered treatment fee information (KOGL Type 1). Prices of individual institutions are not stored or published; only aggregate statistics are.
- National statistics (dental clinics): the minimum, maximum, average and median amounts per item for dental clinics from HIRA's annual statistical tables, published as is (official values, sample size not disclosed).
- Provincial statistics: regional figures from the same tables.
- Own aggregation for dental hospitals: our aggregation of the institution-level reports of dental hospitals (type 41) from HIRA's public API, shown with the sample size (N). Groups with fewer than 5 institutions are excluded.
- Price data as of July 6, 2026; reloaded at least once a year in line with the publication cycle.
Publishing principles
- Facts only. No evaluations, recommendations by quality or rankings of any clinic.
- No per-clinic non-covered fees are published; only regional and institution-type aggregates.
- Reviews and ratings from map platforms are not collected or republished without permission.
