WATER AND SODIUM HYPOCHLORITE INDICATING ENDODONTIC MONITORING DEVICES
摘要
Water and aqueous sodium hypochlorite indicating endodontic monitoring devices include an endodontic cone formed of a water absorptive material and a color changing system applied to the material that changes to different colors when exposed to water or aqueous sodium hypochlorite within a root canal chamber. The water-indicating endodontic cone includes a water absorptive material capable of indicating a change in pH, and a pH insensitive dye. The dye imparts an initial color when the cone is in a dry condition. The pH changing material and pH indicator react in the presence of moisture in a root canal to yield a second color different from the initial color. In the presence of aqueous sodium hypochlorite, the cone changes to a third color different from both the initial color and the second color as a result of bleaching of the dye and/or pH indicator by the hypochlorite ions or aqueous analogs.
