Copper-Zinc-Lead Alloys, Features And Applications (Technical Review)

Summary Objective: The aim of this study was to observe the variability of the level of copper, zinc and manganese in saliva amongst women with hypoestrogenia, treated and untreated with hormone replacement therapy (HRT). Methods: The study was conducted on a group of 60 women treated and untreated with HRT. Half of the patients were after natural menopause and other half was after surgical removal of ovaries. Research on micronutrients in non-stimulated saliva and blood serum was carried out in 2005. Tests on saliva were repeated in 2010. Investigation of bone mineral density (BMD) of femoral bone was performed in year 2010. Results: Statistical analysis of concentration of copper and zinc revealed a linear correlation between the levels of these microelements in blood serum and saliva. The study revealed that HRT has a beneficial effect on BMD and the concentration of copper and manganese in saliva and blood serum of patients after the menopause. Patients treated with HRT showed higher BMD values than groups not treated with hormones. Conclusions: Saliva appears to be a promising diagnostic material which can be used to analyze the content of trace elements, but further research should be carried out on a broader research group.

Background: This study aims to determine and compare the levels of trace elements copper, zinc, selenium and chromium in GCF and serum of patients with periodontitis and healthy individuals. Methods: This cross sectional study includes 24 study subjects recruited from the patients reporting to the Department of Periodontics , Tagore Dental College Chennai. All the selected patients were subjected to a clinical examination done by a single examiner. The estimation of trace elements Copper, Zinc, Selenium and Chromium in GCF and serum is performed using Perkin Elmer optima 5300 Inductively Coupled Plasma Emission Spectrometer (ICPOES). Results: GCF and serum copper levels showed no significant difference in both periodontitis and healthy groups . Selenium levels tend to be the same in both groups. Serum zinc levels are more in periodontitis patients than healthy subjects (p less than 0.01). GCF chromium levels are found to be more in patients with periodontitis than healthy. Conclusions : More research is therefore needed to monitor the role of these trace elements C with an increased sample size to ascertain whether they are associated with a reduced risk of periodontitis.
