Resumo: dc.description.abstractThe goal of this paper is to examine the composition of saliva samples collected from patients suffering from peri-implantitis and try to find a correlation between the detected elements using TXRF and the disease. We did so for four samples from different regions of the patient's mouth were collected from four subjects. We then added a gallium internal standard to all the samples and let it dry in an oven to perform the measurement using a S2 Picofox from Bruker, then the obtained spectra were analyzed using the Spectra 7 software. By performing the analysis, we noticed that the elements detected on every sample were: Phosphorus, Sulfur, Chlorine, Potassium, Calcium, Iron, Zinc, Bromide and Rubidium. Titanium was also detected on 72% of the samples. Our initial assumption was that the concentration of titanium would be greater in the regions near the compromised implants due to corrosion. We actually found that the titanium concentration was greater at the gingival sulcus of health implants. The results also showed that the concentration of iron and sulfur were greater at the gingival sulcus of compromised implants than anywhere else in the mouth. With these findings, we can confirm that the TXRF is a reliable technique to analyze elements from trace to macro-concentrations and can be used to monitor salivary levels of several elements, but so far, we couldn't find a relation between peri-implantitis and implant corrosion.pt_BR
