In this research, fluoride concentration in five brands of bottled-water samples sold in Lafia city (A, B, C, D and E) was investigated. Five different batches of each brand were analyzed. Samples were determined via potentiometric, and photometric methods. The mean concentration of fluoride within the investigated samples, were of the range 0.30 – 0.44 mg/L which were below WHO recommended limit, except sample B (0.53 mg/L) which was within the recommended limit. In the photometric method, the concentrations of the samples were within the range of 0.51 – 0.88 mg/L which were within WHO recommended limit. The outcome of this research suggests that within areas where there is elevated content of fluoride in water, bottled-water should be consumed instead of tap water because the former minimizes the danger of fluorosis. However, people who majorly drink bottled-water maybe at higher risk of dental caries; and need to take fluoride supplements. In this study, concentration of fluoride determined by photometric method was significantly higher than that of ISE method (P<0.05). Hence, photometric method was more sensitive than the ISE method.","PeriodicalId":299805,"journal":{"name":"Oriental Journal of Physical Sciences","volume":"47 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140502293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

People clipped with orthodontic wires may take copper barrel brandy orally, with dilution of without dilution. How far the orthodontic wires will be affected by these items? To find an answer the present research work is undertaken. Ni-Cr alloys have good corrosion resistance. This is attained by arrangement of protective oxide film in oral environment. Corrosion resistance of orthodontic wires prepared from Ni-Cr alloy in artificial saliva in existence & nonexistence of copper barrel, water and soda water has been estimated by polarization technique. It is generally noted that corrosion resistance of Ni-Cr alloy in synthetic saliva in existence of copper barrel, water and soda water decreases.

In actual practice, there are extensive assortment of techniques ranging from simple ones like sample weighing to sophisticated methods using highly dedicated instrumentation. The most primordial technique is the classical method like gravimetry (based on weight measurement), titrimetry (based on addition of a solution to sample solution). Spectrochemical methods are based on the measurement of spectrum of the samples using different instruments. Electroanalytical methods utilize the potential or current of a electrochemical cell for determination of sample concentration. Chromatography is a separation based technique used to isolate the analyte from the other species to enable interference free determination. 1 Spectrochemical methods depends on spectroscopy which is the study and measurement of the spectrum produced upon interaction of sample with electromagnetic (EM) radiation as function of frequency or wavelength of radiation. There are diverse forms of spectroscopy namely acoustic resonance (Cost effective spectroscopy technique in acoustic region, mainly ultrasonic & sonic regions), X-ray photoelectron (relies on diffraction patterns created while X-rays pass through crystalline materials), circular dichroism (helps in differentiating left & right circularly polarised light by sample), Ultraviolet-Visible (UV/Vis) Spectroscopy (probing the electronic structure for identification of compounds), NMR Spectroscopy (measure magnetic fields around nuclei using radio waves), Infrared Spectroscopy (IR region of EM radiation is used), Raman spectroscopy (for identification of molecules based on","PeriodicalId":299805,"journal":{"name":"Oriental Journal of Physical Sciences","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130841577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
