The Step Response of Tooth and Its Supporting Structures

Abstract

The purpose of this study is to establish a new method which can objectively catch the acceleration step response of the tooth supporting structures.
The fracture of the pencile-lead (the protruded length: 5mm, the diameter: 0.3mm, the degree of optical density on paper: 2H) for generating a source as a step function was applied to the tooth surface.
As the results, this source conventionally oscillated tooth and its supporting structures with reproducibility.
