内容記述 | To investigate the mechanism of fracture of teeth, the starting point of the fractured site was specified and the structural appearance was observed by staining the tooth surface and cyclic-stress loading test. Using a human premolar tooth, a triangular transverse groove was formed on the dentine surface to the mesiodistal direction and cyclic-stress loading was added to break the specimen to measure the stained range of penetrated pigment observed on the broken surface after testing. Next, the broken surface was observed using SEM from a bird's-eye view as well as side sectional view and fractography analysis was done. As a result, the following findings and conclusion were obtained. Results: 1) The fractured region that indicates the starting point of the fracture was clearly detected with silver staining. 2) An irregular structure in a wave-like design existed in the silver stained region on the broken surface. 3) The apical region of the wave-like structure zone was generally even on the broken surface. 4) The apical region of the wave-like structure zone was assumed to be a kind of striation structure peculiar to dentin. Taking the above into consideration, it was indicated that in fractured teeth, cracks occur first by repeated stress then the beginning of the crack is notched to operate as a site of action leading to immediate brittle fracture. | |||||
