FT-Raman Spectroscopic Studies of Nd/YAG Laser Irradiated Human Dental Enamel
FTR-Raman Spectra of human dental enamel, both laser-irradiated and untreated, are reported. Spectra are compared with hydroxyapatite. It is evident that unlike the CO2 laser, the Nd/YAG laser does not induce any chemical change in dental enamel.
متن کاملa comparative study of enamel surface roughness after bleaching with diode laser and nd: yag laser
introduction: bleaching process can affect surface roughness of enamel, which is a vital factor in esthetic and resistance of tooth. the aim of this study was to compare surface roughness of enamel in teeth bleached using diode and neodymium-doped yttrium aluminium garnet (nd: yag) lasers with those bleached using conventional method. methods: in this study, 75 anterior human teeth from upper a...
متن کاملInfluence of shielding gas composition on weld structure in pulsed Nd: YAG laser welding
This work studied the effect of additions of carbon dioxide to argon shielding gas on the weld shape and microstructure of ST14 steel in pulsed Nd: YAG laser welding. By additions of carbon dioxide up to 15%,the weld area and depth/width ratio decreases while rising of carbon dioxide up to 25% causes increasing of weld area and depth/width ratio. It is observed that the weld metal microstructur...

متن کاملInvestigation of Microstructure weld zone of Hastelloy X Pulsed Nd-YAG laser welds
In the present study, the microstructure of welded zone of Hastelloy X sheets with thickness of 1 mm via pulsed Nd-YAG laser welding were studied. This welding process was done by autogenus and conductive method. Microstructure were observed by metallurgical OM and SEM. Results shown Solidification of the weld metal is dendritic. The dendrites in the central zone of the welding are fine and equ...
