Device for detecting injuries of early cavities not cavitated

摘要

Device for detecting lesions of uncavitated caries, comprising: a measurement electrode (300) having an electrically conductive tip (260), said tip being dimensionally configured to fit within a fissure (120; 220) having a width in the range between 0.05 and 0.3 mm and a length in the range between 0.5 and 1.5 mm in the tooth of a patient and to provide electrical contact with fluid (220) at the bottom of the fissure ; a reference electrode, configured for electrical contact with the patient's body; and a measurement means for determining the electrical conductance between the measurement electrode and the reference electrode, wherein the device is further configured to receive a current source to supply electrical current between the measurement electrode and the measurement electrode. reference.
