Division for Tooth and Supporting Tissues Disease
Restorative Dentistry and Endodontics
Our clinical team diagnoses and treats diseases in teeth and periodontal tissue with an aim of encouraging maximum preservation of them. Removing courses of the diseases and restoring the morphology and function of teeth enable to maintain healthy oral and body conditions.

① Diagnose and restore dental caries:
We restore the morphology and function of teeth by using resin composites, metallic and ceramic materials after removing infected tissue in a cavity with maximum consideration of protecting dental pulp.
② Treat discolored teeth:
We achieve optimal dental esthetics for discolored teeth by whitening or laminated veneer with resin composites or ceramics.
③ Treat dentin hypersensitivities:
We diagnose and treat dentine hypersensitivity, which reacts to cold and hot stimulus in spite of no cavitation.
④ Diagnose and treat pulpitis:
When a deep caries expands into dental pulp and causes sever pain, such pulp needs to remove in order to relief from the pain. We remove pulp tissue with inflammation and fill the root canal with modern materials.
⑤ Diagnose and treat periapical periodontitis:
Once a root canal is infected with oral bacteria, occlusal pain, gum swelling and pus discharge might occur. In such a case, we recover a sound condition by removing invaded bacteria from an infected root canal. In a refractory endodontic case, sometimes, surgical treatment is applied, where an infected root tip is removed followed by filling with dental cement at the front of residual canal to prevent outflow of contaminant from the canal.
⑥ Treat fractured teeth:
We try to preserve fractured teeth, which are previously extracted, as much as possible. Once we extract the fractured tooth, and we return it in place after adhering the fracture sites (re-plantation).
⑦ Treat marginal periodontitis:
When inflammation is initiated at the periodontal tissue (gingivitis or periodontitis), we control inflammation by eliminating the source of infection with an aim of keeping the longevities of the teeth.
Periodontics and Endodontics
- Prevention, diagnosis, and treatment of dental caries and other diseases of dental hard tissue
- Diagnosis and treatment of periodontal diseases, pulpal and periapical diseases
Our department has been focusing on the treatment of periodontal diseases and the development of new diagnostic and therapeutic procedures for severe periodontitis. We provide professional medical cares aiming at keeping teeth and tooth-supporting tissues healthy for as long as possible.
Department of Periodontics and Endodontics is appointed as a specialist training institution of the Japanese Society of Periodontology and the Japanese Society of Conservative Dentistry.

■Development of new periodontal regenerative medicine
We have been investigating the efficacy and the safety of FGF2 (basic fibroblast growth factor) in periodontal treatment. REGROTH®, a treatment that utilizes fibroblast growth factor-2 (FGF-2), has been studied for many years in our hand and was finally approved for production on September 28, 2016 by the Ministry of Health, Labour and Welfare of Japan. This product is the world’s first and only pharmaceutical that includes growth factors developed for the purpose of periodontal regeneration. We have also been investigating the utility of autologous adipose tissue-derived multi-lineage progenitor cells transplantation therapy at the Cell Processing Center in the Center for Translational Dental Research.
Preventive dentistry is the science and technology to prevent oral diseases, to maintain normal oral functions and to promote oral health actively for an individual and a mass. The aim of preventive dentistry is to contribute to progress in QOL (quality of life) in people’s health and to lengthen the life of health (period in which people can send daily life healthily and independently) by maintaining and promoting synthetic (physical, mental and social) health through oral health. Therefore, in addition to prevent oral diseases, it is the significance of preventive dentistry to contribute for people to send high quality of living and life by maintaining and promoting oral functions such as to eat various foods with well-balanced, deliciously and tastily, and to talk pleasantly. In department of preventive dentistry, on the basis of this fundamental view, we conduct study, education and clinic.

It has been reported that 80-year-old people, whose age is the average life in Japan, have approximately only ten teeth. Two major causes of tooth loss are caries and periodontal disease. In Preventive Dentistry, we mainly prevent caries and periodontal disease, and our aim is “eat with one’s teeth in one’s lifetime.” To prevent caries, we instruct healthy eating habits, apply fluoride, instruct teeth brushing, and apply fissure sealants and so on. To prevent periodontal disease, we instruct teeth brushing, conduct dental
scaling and teeth cleaning and so on, and instruct to quit smoking at request. In addition, we conduct consultation and treatment for halitosis. To maintain oral health, we insist that periodical oral health management is necessary. Most of patients, who have dental examination at preventive dentistry, visit our clinic periodically such as every 3 months and every 6 months, and have checkup for oral diseases and preventive treatment.
The Pediatric Dental Clinic was started as the Clinical Room for Pediatric Dentistry in 1964 (chief: Dr. Sadahiro YOSHIDA). After Dr. YOSHIDA moved to Gifu Dental College, Dr. Shizuo SOBUE was designated as the chief in 1971, and then upgraded the facility to the Pediatric Dental Clinic in 1975 and became its head. Dr. Takashi OOSHIMA was designated as the head of the clinic in 2002 and Dr. Kazuhiko NAKANO was designated as the head in 2014. Presently, there are 24 dentists working in the clinic, who treat children and adolescent patients.

■ Clinical practice
We admit children and adolescents as patients at their first visit up to approximately 15 years old for various dental problems. Dental caries and periodontitis are two of the major categories, while treatment for traumatized teeth is also performed. In addition, fluoride application, space maintenance, occlusal guidance and examinations of periodontal bacterial species, which are not covered by national insurance as ordinary treatments, are provided. Furthermore, we accept patients who have great fear during dental treatment or those with systemic diseases. At our clinic, our Mother’s Class is emphasized, in which instruction to guardians about prevention of dental caries and periodontal diseases is provided, as well as periodic examinations for early detection and early intervention of dental problems. Five specialists for pediatric dentistry qualified by the Japanese Society of Pediatric Dentistry (JSPD) and 1 instructor qualified by the JSPD to train specialists are serving at the Clinic, who not only treat patients but also instruct undergraduate and postgraduate students as well as young dentists for the purpose of training as many specialists as possible.
■ Clinical research
In our system, patients and their guardians receive tooth brushing and diet instructions at the second visit (the Mother’s Class). We also perform examinations to detect oral bacterial species related to dental caries and periodontal diseases using saliva or dental plaque specimens from both patients and guardians, with the results, such as total number of cariogenic bacteria and periodontal species, reported during the following visit. This scientific information provides motivation for the patients and guardians to improve their oral health. In addition, we are presently constructing a method for determining high-risk subjects for dental caries or periodontal diseases based on the results of these examinations and clinical conditions
