Application of Scanning Acoustic Microscopy for Detection of Dental Caries Lesion

Abstract

13 Open Journal of Stomatology dentins were visualized using two-dimensional color images. A strong correlation was observed between the acoustic impedance value, which indicates the hardness of the elastic region, and the Knoop hardness, which indicates the hardness of the plastic region. The results of the present study indicate that acoustic impedance accurately reflects the hardness of dentin.
