Disease Management DentistryOral and Maxillofacial Oncology and Surgical Sciences

As long as it is a part of the body, various tumors, including cancer, also occur in the maxillofacial and oral cavity regions. In particular, the oral and maxillofacial region is characterized by the occurrence of region-specific tumors due to the presence of teeth and salivary glands, which are components that are not found in other parts of the body. The Division of Oral and Maxillofacial Oncology and Surgical Sciences conducts clinical and basic research using cell biological, molecular biological, genetic, and pathological approaches in order to promote the diagnosis and treatment of these tumors. We aim to create new diagnostic and therapeutic methods as the outcome.

Furthermore, since the oral and maxillofacial region has important functional and morphological roles, we have a mission to promote surgical treatment and research that considers these roles in collaboration with the Division of Oral and Maxillofacial Reconstructive Surgery and other fields.
