Photograph-Processing Facility

At this facility, analog images from microscopes are digitally processed. Such procedures as image monitoring, image processing, image analyzing, and 3-D image are conducted in this section. Researchers also have access to printers of all sizes. Conventional photos are developed in the darkroom.

Biomaterials Research Facility

There has been a remarkable advancement of biomaterials in dentistry.  It is important that biomaterials do not harm cells.  Thus, biological function and biological safety must be secured before investigating biocompatibility.  One of the features of this facility is the ICPS (Inductively Coupled Plasma Spectrometer) which is used to analyze dissolution and corrosion of biomaterials in vivo.  The Servopulser is used to make precise analysis of the strength.

Tissue Culture Facility

Both organ culture and tissue culture are conducted at this facility.  Tissue culture is used for research of cell proliferation, cell differentiation, metabolism, carcinogenesis, and aging.  In recent years, the mechanism of bone formation and bone absorption are investigated by isolating osteoclasts, osteoblasts, and fibroblasts.  Regenerative research is conducted on bone, teeth, and periodontal tissues with bone marrow stem cells.

Masticatory Function Research Facility

Various experimental equipments are available for the research of masticatory movement.  Muscle force changes and decreases with the advancement of age.  Thorough mastication activates the muscles and delays the aging of the maxillofacial complex.  Mastication plays an important role in general health.  Research at this facility focuses on the mechanism of the development and decline of masticatory function in relation to age.
