ABSTRACT:
A method of detecting periodontal disease involves attaching a vibration detector to the tooth, causing the tooth to vibrate by means of striking the tooth with a hammer, and then picking up signals corresponding to of the vibration of the tooth for processing by a dynamic signal analyzer and a microprocessor using Fourier analysis. The location of the natural frequency of the tooth is determined based on the lowest point in the image mode and the point of contraflexure in the real mode.
