| Research Abstract |
Diamine silver fluoride (Saforide) is clinical use for prevent of progress of dental caries and desensitizing for hypersensitive tooth. Unfortunately, diamine silver fluoride stained tooth black due to silver precipitation. To overcome this drawback, ammonium hexafluorosilicate was prepared. The purpose of this study was to evaluate the occluding ability of dentin tubules and acid resistance of bovine tooth after ammonium hexafluorosilicate treatment. It was concluded that ammonium hexafluorosilicate is useful for the treatment of dentin hypersensitivity and prevent of progress of dental caries since ammonium hexafluorosilicate treatment occluded open dentin tubules completely with silica-calcium phosphate precipitate and increased acid resistance of bovine tooth without changing the color of tooth.
