| Outline of Final Research Achievements |
This study forced corrosion resistance of dental implant made of titanium and titanium alloy in occurring implantitis which there is one reason of removal dental implant. Porphyromonas gingivalis, which is one of periodontric bacteria, yields sulfide, and we investigated the influence of its sulfide on titanium corrosion. Consequently, titanium was discolored in alkaline sulfide-containing solution, because the titanium oxidized by alkaline and sulfide conditions.
