It was found that the surface of titanium became porous and titanium hydride was formed after the surface treatment of titanium by etching in 48% sulfuric acid. After the treatment in 5M-NaOH, the amount of sodium titanate on the acid-etched surface was larger than that on untreated titanium. However, titanium hydride still existed after soaking in simulated body fluid for 3 weeks. Titanium hydride disappeared and titanium oxide was formed after vacuum firing.

Denture adhesives are widely used for edentulous patients in order to improve retention and stability of their dentures. However, little information is available on mechanical properties and functional effects of the materials. This study evaluated the dependence of dynamic viscoelastic properties on frequency for the denture adhesives.

The purpose of this experiment is to investigate the performances of two types of monomer liquids of 4-META/MMA-TBB resin when they are combined with eight different types of polymer powders. The working time, setting time, and the bond strength to enamel, dentin, and two kinds of metals for each combination were examined. The working time and setting time was same action was shown. Moreover, the tensile bond strength test of any of these monomer/powder combination showed more than 10 MPa. The results indicates that clinical conveniences become greater by choosing any of these appropriate monomers and powders.

We evaluated the cellular reaction of macrophage-like RAW264 cells cultured in the medium containing Ti particles with a mean diameter of 10 micrometer. RAW 264 phagocytized Ti particles. The cell viability and NO production of RAW264 cultured in the medium containing Ti particles for two days declined to about 90% those of control RAW264 cells. Such decline appeared to be attributed to phagocytosis-related inflammatory cytokines and oxygen free radicals that reduced the cell proliferation.

Thin films of HMDSO (hexamethyldisiloxane) were plasma-polymerized on the 15mm round Thermanox coverslips, followed by low energy O
2 plasma treatment with different time duration. The surface wettability was characterized by contact angle measurement with distilled water. By controlling the O
2 treatment time, 6 kinds of discs with surface contact angles respectively 0, 20, 40, 60, 80 and 110 degrees were produced. The wettability of the surfaces was kept stable when stored in distilled water for 24 hours. The fibroblast cell line L929 was used in the following experiment. The discs were put into 24 well culture dish and cells were seeded with a density of 20000 per well. In 6, 12 and 24 hours the adhesion behavior of the cells on surface with different wettability was investigated. The results showed that cells seeded on hydrophilic surfaces attached more quick and larger quantity than hydrophobic ones.

We prepared DNA/lipid complexes from DNA and amphiphilic lipids. The antibacterial and antifungal activity of denture base resins containing DNA/lipid complexes were evaluated by measuring inhibition zone around the disk shaped denture base resin containing DNA/lipid complexes. The resins containing DNA/lipid complexes 10wt% or above showed the antibacterial and antifungal activity.

Resin modified glass-ionomer cements (RMGICs) possess beneficial properties, including physicochemical adhesion to tooth structures and the release of fluoride ions, but still show margin microleakage. We have added 5-20% spherical silica filler to the RMGIC and got a RMGIC with higher mechanical properties. Therefore, in this study we examine the effect of spherical silica filler addition on the marginal gap and shear bond strength of RMGIC with the tooth substrates.
