Abstract

The subject of the invention is a method for determining tooth vitality comprising a step of applying radiation and a step of measuring the radiation being the tooth's response to stimulation with radiation to obtain a measurement signal, and then a step of processing the measurement signal to determine time-varying components associated with blood flow to obtain information for assessing tooth vitality. In the step of applying radiation, radio waves with a frequency in the range of 1 to 25 GHz are applied to the tooth. In the step of processing, the time-varying components associated with blood flow are discriminated. The tooth vitality assessment is made on the basis of a comparison of at least one parameter of the components associated with blood flow with a predefined threshold. The subject of the invention is also a measuring device for determining the patient's tooth vitality, comprising a measurement module (1), a transceiver (2) connected thereto and provided with an arm comprising a transmission line (4), and a radiation applicator (5), the measurement module being adapted to measure the radiation being the tooth's response to stimulation with radiation to obtain a measurement signal. The transceiver (2) is adapted to transmit and receive radiation with a frequency in the range of 1 GHz to 25 GHz. The control module (10) is adapted to discriminate time-varying components associated with blood flow. The computer program product according to the invention is adapted to be run in the control module of the device according to the invention and comprises a set of instructions causing the method according to the invention to be performed.
