ENAMEL SURFACE RESTORATION
Early in vitro studies showed SANGI nano<mHAP>'s restorative effect on microscopically damaged tooth surfaces.
The studies were conducted using healthy extracted human teeth. Their surfaces were treated with acid to create artificial enamel surface damage and roughness. Afterwards, the teeth were brushed or immersed in a nano<mHAP> solution, and for comparison, immersed in artificial saliva. Bacterial adhesion to these surfaces was also evaluated.
Results, evaluated using **Scanning Electron Microscopy (SEM) and Field Emission Scanning Electron Microscopy (FE-SEM)**¹², showed that nano<mHAP> fills and restores microscopic defects on the enamel surface, returning the enamel to near its original smoothness.
Furthermore, it was found that the restored smoother enamel surface reduces bacterial adhesion, which helps protect teeth from plaque formation³.
