Community Social DentistryInternational Oral Health

The field of International Oral Health makes evident the large connection between individual health including oral health and our communities, and aims to work with local guvernments to build a healthy society.

We have carried out research on the influence that the social capital, or bonds to humans and society have on dental health. We have shown socioeconomic status has an impact on the number of remaining teeth in a cohort study. We have also established the number of remaining teeth has associated with the tendency of becoming nursing care-dependent and pneumonia deaths.

To deal with the increasing aging population in both developedand developing countries, we have constructed and started a nationwide introduction of a program combining nutritional guidance improvement of physical function, and oral function to prevent the need for nursing care.

We make proposals necessary for the construction of regional comprehensive care systems that are able to provide medical and nursing care and.

We are working on education of young students in international support for developing countries, as well as analyzing the oral health condition and health inequalities in Japan and deepening our understanding of the dental care system, long term care insurance system for the elderly, and dental public health.
