NOVEL METHOD FOR THE ESTIMATION OF TOOTH SURFACE HARDNESS USING REFLECTION SPECTROPHOTOMETRIC ANALYSIS AND DIAGNOSTIC TECHNIQUE BY NON-CONTACT METHOD

摘要

PURPOSE: A method for predicting the hardness of a tooth surface using a reflecting spectrophotometric system and a contactless diagnostic technique of tooth state are provided to inspect the various surfaces of teeth and measure treatment drug effects without the deformation of or damage to specimens. CONSTITUTION: A method for predicting the hardness of a tooth surface using a reflecting spectrophotometric system and a contactless diagnostic technique of tooth state predict the physical state of teeth only with optical characteristic by the comparison of correlation between tooth surface hardness and the optical characteristic. A method for measuring the hardness of a tooth surface is provided to measure Vickers hardness.
