| Summary: | 碩士 === 國立高雄應用科技大學 === 機械與精密工程研究所 === 102 === In recent years, the aging of our population continuing, along with aging, the human diseases also will come, one of the most critical is the oral problems. People often because the improper manner of eating habit and clean teeth, thus causing odontopathy. Dental disease is originally from plaque begins. Along with the food we eat, the residue stuck in between the teeth and gums. After twelve to fifteen hours, the residue hardened and form dental calculus, and finally because of the acid produced dental calculus cause tooth decay. After suffering decayed of the tooth will according to the extent of the damage and get corresponding remedial measures. If it's a slight decayed, use the fill material for fillings, if itself suffered severe decayed, consider to replacing the entire tooth and implant dentures.
But both the fill material and dentures are needed to understand the relevant material properties of tooth, as a basis of production. Because the difficult to obtain the human teeth and have a moral doubts, therefore, this study will test the relevent properties of the porcine teeth. The second largest molar teeth will as a main part for test. In the test, the dentine will be dividing in to two force directions to be test. The SHPB will be the main facilities in this study. The SEM was used to observe the microstructure of dentine. Finally by using nanoindenter to explore it’s microscopic mechenical properties of the dentine.
