Research field introduction

Endodontology and Operative Dentistry

We are committed to enhancing our three core strengths—diagnostic ability, research capability, and clinical expertise—while advancing innovative techniques for tooth preservation.

Our department was established in 1971 (Showa 46) as the Department of Conservative Dentistry Ⅱ. While the department primarily focused on restorative dentistry, its scope has since expanded to encompass both restorative dentistry and endodontics.
Guided by our philosophy of “Saving Teeth,” we uphold three fundamental principles: (1) do not drill teeth unnecessarily, (2) do not remove the dental pulp unnecessarily, and (3) do not extract teeth unnecessarily. These principles form the foundation of our clinical practice, research, and educational activities.
In Japan’s super-aging society, many people wish to retain and use their natural teeth for as long as possible, and interest in tooth preservation continues to grow. In fact, national dental health surveys have shown a significant increase in the number of natural teeth retained by older adults in recent years.
To address these societal needs, all members of our department work together every day to further strengthen our diagnostic ability, research capability, and clinical expertise.
Our goal is to protect the oral and overall health of our patients while contributing to the well-being of the community and continued advancement of dental science.

Message to students

Conservative Dentistry is the field of dentistry concerned with the etiology, diagnosis, prevention, and treatment of dental caries, pulpitis, and apical periodontitis. As the discipline responsible for managing many of the most common dental diseases, it forms the foundation of clinical dental care and is often the first point of treatment for patients presenting with dental symptoms.
The quality of conservative treatment has a significant impact on the long-term prognosis and survival of natural teeth. Moreover, even a seemingly simple complaint such as “tooth pain” may arise from a variety of underlying conditions, requiring careful diagnosis and individualized treatment planning. To address these challenges, clinicians must continually develop three essential competencies: diagnostic ability, investigative and research capability, and clinical expertise.
In our department, faculty members, researchers, and students work together to strengthen these competencies through both clinical practice and scientific research. We are committed to fostering the next generation of dental professionals who can contribute to the advancement of patient care and dental science.
We welcome students with an interest in Conservative Dentistry to join us in exploring new possibilities in diagnosis, treatment, and research. Through education, clinical training, and research activities, we aim to shape the future of dental care together.
