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.

Summary

Long-established downtown Daegu practice, registered with the national health insurer since 1975 and one of only three Daegu dental practices on the U.S. Embassy Seoul list of English-speaking dentists. Led by Dr. Lee Sang-jik (Kenneth S. Lee); prosthodontics and comprehensive general dentistry.

The U.S. Embassy list prints the older lot-number address "128-1 Deok San-dong, Jung-gu"; the road-name address and the phone number both match the HIRA institution record for Iyeonhap Chigwa-uiwon (Lee Yonhap Dental Clinic), so the two refer to the same practice.
