Abstract:
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.
Abstract:
PURPOSE: A diagnostic technique of initial caries by optical parameters is provided to discover disease conditions of various initial caries which is not discovered by existing research. CONSTITUTION: A diagnostic technique of initial caries by optical parameters quantitively monitors the index grade of the initial caries only with optical analysis by comparison of correlation between tooth surface hardness and optical characteristic. Vickers hardness is measured for the measurement of the tooth surface hardness.
