Located in Aioicho, Naka Ward, Yokohama City, Yokohama City Dental Health Medical Center offers barrier-free accessible facilities and provides services in English and Korean. This specialized medical institution provides dental treatment for individuals with physical and mental disabilities from 9:00 AM to 5:00 PM, after which patients are required to return to the referred dental clinic or a nearby dental clinic. The emergency dental care system is comprehensive, offering year-round night emergency dental treatment from 7:00 PM to 11:00 PM, and holiday emergency dental treatment from 10:00 AM to 4:00 PM including Sundays and holidays. Registration is accepted until 30 minutes before the end of treatment, and in some cases, treatment may end earlier depending on the procedure and congestion. This center targets patients who require reasonable accommodation that is difficult to treat at general dental clinics, providing treatment primarily using general anesthesia and sedation. Treatment under physical restraint is determined after considering urgency, non-substitutability, and temporariness, and for patients with cerebral palsy where primitive reflexes persist, treatment continues using positions based on neurophysiological reflex inhibition.
