The PhD in Oral Health and Welfare Science at Niigata University is a doctoral degree programme (typically 3 years) offered through the Graduate School of Medicine, Dentistry and Health Sciences (transitioning from the former Graduate School of Medical and Dental Sciences). This program builds on the Oral Health and Welfare Program, emphasizing advanced interdisciplinary research at the intersection of oral health sciences, social welfare, and healthcare practices. Doctoral candidates engage deeply in original research under faculty supervision, exploring topics such as oral health promotion, eating and swallowing functions in ageing populations, comprehensive care strategies, and welfare support systems. The curriculum focuses on developing high‑level analytical, methodological, and academic writing skills necessary to produce a doctoral dissertation that contributes new knowledge to the field. The programme prepares graduates for careers as researchers, educators, policy specialists, and senior professionals who can lead innovation in oral health and welfare both in academic settings and in community or clinical practice. Admission requires a relevant master’s degree and often involves demonstrating research potential and alignment with faculty expertise.
