Disease Management DentistryDental Informatics and Radiology

 In April 2020, the name of our division was changed from “Oral Diagnosis” to “Dental Informatics and Radiology” in response to the recent diversification of medical imaging modalities and advanced utilization of medical informatics. In recent years, dental imaging has advanced from two-dimensional X-ray imaging, such as intraoral or panoramic imaging, to three-dimensional digital imaging, such as dental CT and intraoral scanning. Various medical support systems are being developed using these digital technologies. We hope to contribute to equalizing high-quality dental care through the development of new dental imaging devices and the use of artificial intelligence (AI) and remote communication technology in medical informatics.

 In our division, the diagnostic imaging using CT, MRI, US, and Nuclear medicine are mainly performed. Various supports for dental treatment using imaging data such as implant simulation are also provided. In addition, oral management for patients with systemic diseases in collaboration with the Division of Perioperative Oral Health Management.

 Regarding research, we are developing new medical devices in collaboration with other faculties and researching on improving diagnostic accuracy for oral and maxillofacial diseases using the latest imaging devices or AI.

 For information on our other research, please see below.


Topics of Research

  • Development of new medical devices.
  • Imaging diagnosis of oral and maxillofacial lesions.
  • Relationship between systemic diseases and oral conditions.
