Abstract
Method for electronically indicating a concentration of an irrigation solution in a root canal (RC) of a tooth (T), using a device able to be electrically connected to an endodontic instrument engaged in the canal and to a labial electrode, and including a screen to display the progression of the instrument in said canal relatively to a critical apical point of reference such as the cemento-dentinal junction (CDJ), said device being furthermore able to measure, in the vicinity of said point of reference, by conductimetry, a concentration of an electrolyte irrigation solution injected into the root canal.
Claims8
A method for electronically indicating a concentration of an irrigation solution in a root canal of a tooth, the method comprising:
- electrically connecting a device to an endodontic instrument engaged in the canal and to a lip electrode;
- displaying, on a screen of the device, a progression of the instrument within said canal up to a critical apical reference point, such as a cemento-dentinal junction;
- measuring, by means of two or more measurement points, in proximity to the reference area, by conductimetry, a concentration of an injected electrolyte irrigation solution within the root canal;
- calculating, based on the measurement points, a concentration level of the solution injected into the canal in the previously defined area;
- indicating, on the screen of the device, the measured concentration of the electrolytic irrigation solution injected into the root canal;
- and
- storing the measured concentration in the device even when the endodontic instrument is withdrawn from the root canal.
