Abstract

PURPOSE:To quantitatively elucidate the properties of periodontium only by lightly performing hammering, by catching a rocking vibration waveform generated by the hammering of the teeth and integrating the same to calculate a vibration waveform to display the same on a display apparatus as a teeth shaking degree. CONSTITUTION:When the teeth is lightly tapped with a hammer 9, the teeth is rocked in matching relation to the healthiness degree of the gum but this shaking vibration is caught as a shaking analogue signal by a sensor 1. The vibration analogue signal successively passes through the first amplifier 11, an analogue delay 4, the second amplifier 12 and an A/D converter 5 to be converted to a shaking digital signal. The rocking analogue signal branched from the output of the second amplifier 12 is inputted to an integrator 6 and inputted to the A/D converter 5 as an integrated analogue signal to be converted to an integrated digital signal. A memory start signal is outputted from a controller 7 and the input of the shaking digital signal and the integrated digital signal to a memory apparatus 8 is started. The data stored in the memory apparatus 8 is taken in the controller 7 to operate a rocking degree which is, in turn, outputted to a display apparatus 14 through a display interface.
