Solubilizing agent of carbonated calcium hydroxide-based root canal filler and solubilizing method

Abstract

To dissolve a calcium hydroxide-based root canal filler having been carbonated and fixed within a root canal, which cannot be removed from the root canal by means of a reamer and a file, during doing the root canal treatment again, and to sterilize the root canal, the solubilizing agent of the carbonated calcium hydroxide-based root canal filler includes water containing 1 to 60% by weight of the whole of at least one acid selected from the group consisting of phosphoric acid, gluconic acid, fumaric acid, lactic acid, glycolic acid, propionic acid, malic acid, maleic acid, citric acid, succinic acid, tartaric acid, acetic acid, glycerophosphoric acid, and malonic acid; and 0.1 to 30% by weight of the whole of at least one sterilizing properties-imparting agent selected from the group consisting of an iodine preparation, a surfactant, a bactericide, hydrogen peroxide, and limonene.
