Abstract

The elastic modulus of fresh human dentin and alveolar cortical bone have been measured in this present work by laser speckle photography which is a non-contact, non-destructive and visual method with a high sensitivity, simple optical system and easy calculation. So it is more suitable than the present strain gauges to measure in-plane displacement of tooth and bone whose specimens are so small and are anisotropic. A special loading apparatus and a technique of sharpening fringe have been tried to use in this study.
