Treatment system

The dentists in charge of first-visiting outpatients (hospital lecturers) make diagnoses and decide each patient’s primary dentist. When a resident is chosen as the primary dentist for a patient, the resident discusses the patient’s case with hospital lecturers to produce a treatment plan and works together with them for providing any treatment.

Treatment policy

After proper conduct of informed consent, we make treatment plans according to a patient’s wishes and choose treatment methods through discussion with them. Only then do we perform the necessary tests and treatments.

Description of medical care

The Department of Caries is a clinic office that provides conservative treatment for morphological and functional restoration of a tooth that is deficient because of caries and other tooth hard-tissue diseases. It therefore prevents pulp-related and periodontal tissue diseases. Furthermore, we provide treatment for a root of a tooth with the pulp infected by advanced caries, often accompanied with severe pain (root canal therapy). We also provide dental health education. If caries are left untreated, they never heal naturally, so early detection and early cure are necessary. A person might have cavities if they experience sweet pain (pain induced by sweet foods such as chocolate), cold water pain (tooth sensitivity to cold water) and hot water pain (tooth sensitivity to hot water). We also perform sedation dentistry for dentinal hypersensitivity, by which teeth, despite having no caries, are sensitive to cold water or ice cream.
Additionally, we perform conservative dentistry using repair materials (adhesive resin) of the same color as the patient’s natural tooth.
