Clinical Department & Center

Oral Medicine


Our department is the first department of oral diagnosis and medicine in Japan, and evaluates the whole body of the patient and provides dental care based not only on dental but also medical science.
We handle all oral diseases including oral malignant tumors such as tongue cancer and gingival cancer, benign tumors such as ameloblastoma, oral mucosal diseases such as leukoplakia and aphtha, salivary gland disease as well as deformations, injuries and cysts of the oral and maxillofacial area, temporomandibular disorders, dental metal allergies, dry mouth (which has been increasing lately), taste disorder, oral candidiasis, and dental psychosomatic diseases such as glossodynia.
We also provide oral care for patients with systemic disease and inpatients of our hospital.


Medical care system

At our outpatient clinic, we provide dental care to more than 2,000 new patients and approximately 200 inpatients each year.

Treatment policy

The oral and maxillofacial area is an important area in terms of function and appearance that greatly affects the quality of life (QOL) of patients.
Accordingly, we accurately understand the condition of the patient, quickly make a diagnosis and provide proper treatment. We also perform minor surgical procedures based on early detection, and take medical approaches to save organs. To comprehensively treat disorders, we also cooperate with other clinical departments.

Areas of medical care

Malignant and benign oral tumors, oral reconstruction, oral mucosal diseases, cysts, inflammation, salivary gland disease, jaw deformity, congenital abnormalities including cleft lip, temporomandibular disorder, injuries, implants, taste disorders, oral psychosomatic diseases

Major tests and equipment


Simple X-rays, nasopharyngolaryngoscopy, as well as CT, MRI, PET and RI sans are performed to detect morphological and functional abnormalities.
Various tests for oral medical diseases, including tests for dry mouth, gustometry, metal allergy tests, an oral magnifying glass test and a candida culture test, are performed.
Tests are not only performed for diagnosis, but also to decide on treatment policies and to judge the effects of treatment.
Although this is still in a research stage, we measure oncogene and new tumor markers in cancer tissues and blood for clinical application.
Others: videofluorographic swallowing studies (VF), sialography, temporomandibular joint arthrography


PET scans of oral cancer are performed in cooperation with the Department of Nuclear Medicine.

Medical care results

We perform surgery for malignant and benign oral tumors, chemotherapy, surgery for maxillofacial injuries and cysts, treatment for cleft lip and temporomandibular disorders, implant treatment, oral reconstruction, eating and swallowing rehabilitation, etc.
We have handled many cleft lip cases, including initial surgery. For malignant tumors and osteomyelitis of the jaw, we perform microsurgery and other procedures.
