Titanium nanoparticles potentially affect gingival tissue through IL-13α2 receptor expression

Abstract: Purpose: To determine the effects of titanium nanoparticles, that may have been scattered after dental implant placement, on gene and promoter expression, and gingival tissue. Methods: Ca9-22 cell lines were used as gingival epithelial cells to assess the effects of titanium dioxide nanomaterials as titanium nanoparticles. Cells were cocultured with or without titanium dioxide nanomaterials prior to gene and promoter expression analysis. Expression of interleukin-13α2 receptor was investigated using real-time … Show more

“…Peri-implantitis is thought to be mainly caused by oral bacteria, but it is possible that the action of nanotitania, which has not been thoroughly investigated, causes a reaction in immune cells and is involved in the destruction of periodontal tissue including the jawbone. In fact, it has been reported that nanotitania increases the expression of the interleukin (IL)-13α2 receptor in gingival epithelial cells and promotes the production of transforming growth factor β1 [ 19 ]. PgLPS can cause an inflammatory response in various types of cells, such as macrophages, fibroblasts, endothelial cells and gingival epithelial cells, through activation of Toll-like receptor 2 (TLR2) and TLR4 [ 20 ].…”
