영문 초록

To understand the micro-mechanical changes and the effects of the fluoride on rat’s femur after administration of sodium fluoride, the threepoint bending test, acoustic emission analysis during the three-point bending test and scanning electron microscopy were performed. The obtained results were as follows: 1. Bone strength increased in the rats given 1, 5, 10 and 20 ppm of fluoride but, there were no statistical significances (p>0.05). 2. With increasing the concentration of fluoride, most AE events released rapidly just before the maximum load and smaller events were recorded than the control group’s. The average of cumulative AE event counts until maximum load of the femur in 20 ppm group were significantly small with respect to the control group’s (p<0.05). 3. Fracture surfaces were well coincide with the results of acoustic emission behavior. Analyses of fracture surfaces indicated that, consistent with its the highest load, rat femur in 20 ppm fluoride group displays the roughest surface.
