A very basic (high pH) calcium hydroxide (Ca(OH)2) solution (also known as slaked lime or milk of lime) intended to be used in dentistry for a variety of purposes including to flush and disinfect root canals and crowns/bridges before final insertion, and to change the viscosity and/or moisten a temporary tooth filling material. It may also encourage the change of fibroblasts (cells which form the connective tissue of the body) into odontoblast-like cells to produce reparative dentine. After application, this device cannot be reused.
