| Research Abstract |
Initial cell attachment and cell proliferation were examined by using gingival epithelial cell (GE1) of mouse origin to examine adhesiveness of epithelial cell of implant in gingival penetration part. As for the titanium treated by hydrothermally in calcium chloride solution, the result of initial attachment of GE1 cell was significantly high compared with untreated titanium. As for the cell proliferation, a significant difference was not admitted though the untreated titanium indicated some high values. Therefore, it was suggested that the hydrothermal treatment with CaCl2 was able to improve the gingiva adhesiveness in the gingiva penetration part of the titanium implant.
