Abstract: The effects of dissolved elements from metal dental restorations are a major concern in lesions of the oral mucosa, and the evaluation of accumulated metal elements, especially their distribution and chemical state, is essential for determining the precise effects of trace metals. In this study, X-ray fluorescence with synchrotron radiation (SR-XRF) and particle-induced X-ray emission (PIXE) were applied for distribution analysis of the trace metal elements contained in the oral mucosa, and the chemical states… Show more

“…By focusing the incident beam down to micron size and scanning over the specimen surface, "micro-PIXE" can also provide images of the trace elemental distribution with high spatial resolution (μm scale) and high sensitivity 21,22) . The method has been used to analyze the distribution of trace heavy elements contained in various soft and hard tissues [23][24][25][26] . The purpose of this study was to evaluate the inhibitory effects of experimental pastes containing S-PRG fillers on bovine enamel demineralization using micro-CT, scanning electron microscope (SEM) and micro-PIXE.…”

“…SR-XRF is highly sensitive and nondestructive, and it is widely used in the trace element analysis of medical and biological specimens. As reported in previous studies [16][17][18] , SR-XRF analysis can be performed with thin, sectioned tissue specimens. Then, comparison with histopathological diagnosis can provide relational information between various changes in tissues and the elemental distribution.…”

“…The multiplication time was set to 2 s in the Ni group, 4 s in both the Ni-Ti group and the Co-Cr group, and 1 s in the sham surgery group and control sides of each animal. The obtained XRF data were processed with PyMCA software (Version 4.7.3) 16,17) . The elemental distribution images were compared with the structure in the adjoining section dyed with hematoxylin-eosin (HE).…”
