Residents in rural areas, individuals incarcerated in correctional facilities, and people with special healthcare needs—including those with physical or intellectual disabilities, children with developmental delays, older adults with functional impairment, and patients with multiple chronic illnesses—have long faced barriers to accessing dental care and achieving equitable oral health. These populations frequently experience delays in seeking care owing to factors such as limited transportation access,, workforce shortages, challenges in care coordination, and elevated clinical risks, all of which contribute to disease progression and increased healthcare burden. As a public regional hospital, Taoyuan General Hospital bears the responsibility of implementing health policies and serving medically underserved populations. Since establishing the Dental Service Center for Patients with Special Needs in 2017, the hospital has integrated outreach dental services for rural communities, dental support for correctional institutions, and specialist care in special needs dentistry. This integrated care model is built upon the core principles of patient safety, quality of care, and service accessibility. Through the efforts of dedicated multidisciplinary teams, standardized treatment protocols, interprofessional collaboration, and a regional referral network, the hospital has improved dental care accessibility and continuity for high-risk populations, while reducing delays in treatment and the risk of complications. This article shares the hospital’s practical experiences as a reference for other healthcare institutions seeking to enhance their dental care services for rural and special needs populations and to promote oral health equality and the sustainable development of healthcare systems.
