School of Life Dentistry at Niigata

The Graduate School

The goal of the Graduate School of the School of Life Dentistry in Niigata is to provide instruction in the theory and practice of dentistry, to act as a source of researchers who can contribute to the advancement of dentistry while acquiring expertise at the highest levels and carrying out independent research, and to foster outstanding research capabilities that through involvement in the industrial world contribute not only to research institutes but also to the local community and society at large.

In the research facilities at the School of Life Dentistry in Niigata, there are three principal areas of specialization: basic science, applied science, and clinical science. The system for directing research is unique and is distinguished by its freedom from preconceived or conventional ideas. Not only are the most advanced research facilities available, various facilities for collaborative research are open for student use, including the Advanced Research Center, and are being actively utilized in research activities. For further details, refer to the Curriculum.

As a rule, the doctorate program requires four years of study, but exceptions are made for students who have completed all the credit requirements and have achieved an outstanding research record before the passage of the required four years. For further information concerning the number of years required for completing courses, see the description of course contents and methods of completing courses.
