Disease Management DentistryComprehensive Dentistry

The Division of Comprehensive Dentistry aims to serve high-quality comprehensive dental care and also practice the management of clinical education to dental students and postgraduate residents.

We emphasize a holistic approach to diagnosing oral diseases, considering not only the condition of the oral cavity but also its relationship with systemic health, lifestyle habits, and social environment. Based on these comprehensive diagnoses, we provide high-quality standard treatments and continuous care for common dental diseases, also pursuing integrated support through collaboration with specialized divisions.

To advance the field of General Dentistry, we actively engage in a wide range of research activities that contribute to its further development.
