Patent ID: 8469708

Claim:
A kit, said kit comprising: a probe syringe, and a current detector device which obtains a circuit resistance value or a circuit impedance value from current flowing in an electric closed circuit including said probe syringe, wherein said probe syringe comprises a thixotropic aqueous dispersed ion conductive paste adapted to be deposited as a layer of ion conductive paste on a tooth, a discharge part formed from a flexible hollow material and being positioned on a top of said probe syringe, the discharge part forming an electrical conductive path of the thixotropic ion conductive paste between the tooth and an electrical conductive member, a cylinder part continuous with said discharge part and retaining said thixotropic aqueous dispersed ion conductive paste, a piston inserted to said cylinder part, and an electric conductive member which ensures electrical conductivity between an inner part and an outer part of the syringe connecting inner and outer areas of said probe syringe, and wherein said current detector device obtains said circuit resistance value or impedance value flowing in said closed circuit through said thixotropic ion conductive paste.
