objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...
background: fluoride is used increasingly in a variety of industries in india. emission of fluoride dust and fumes from the smelters of primary aluminum producing industries is dissipated in the work environment and poses occupational health hazards. objective: to study the prevalence of health complaints and its association with fluoride level in body fluids of smelter workers in a primary alu...
Background and Aims: The systemic and topical preventive effect of fluoride on tooth decay has been reported. The aim of the present study was to determine the fluoride level in imported and national fluoridated dentifrices in the Iranian market. Materials and Methods: Sampling was randomly performed from the main market centers and pharmacies in Tehran. The total fluoride (TF) and total solub...
fluoride is one of the most important elements in the composition of teeth and bones. this element can enter the body via different ways. however, drinking water is the most important way to receive fluoride by a lot of people. an increase in fluoride level in the body causes dental fluorosis and its absence leads to teeth decay. standard rate of fluoride in drinking water is determined by the ...
Abstract Background and Objectives: Fluoride is one of the anions existed in water and soil. Its amount is not the same in different kind of water. Since the most of body's need to fluoride should be provided by drinking water, this study was aimed at determining the fluoride level in water supply of Gorgan rural regions. Materials and Methods: In this Cross-Sectional study, the subjects were a...
Background and purpose: Fluoride is one of current anions in water and soil, but its level varies in different water supplies. Most of the body's requirement for fluoride is supplied through drinking water, therefore, water utility authorities and monitoring organizations should closely control the level of fluoride in drinking water. The aim of this study was to measure the level of fluoride i...
The present study revealed that the total fluoride level in human whole blood is closely related to the renal function. For the undialyzed patients who had not undergone hemodialysis, the total fluoride level in whole blood linearly increased with the increase of creatinine (Cr) value. The increased fluoride was found to be nonionic in the other blood part than serum, while the nonionic fluorid...
background and aims. as a result of poor quality of public water supply in many countries, people have recently turned to bottled water consumption, the fluoride content of which is not generally consistent among different brands. this study sought to measure the fluoride concentration of public water supply in comparison with commercial brands of mineral bottled water available in tehran, iran...
Objectives One of the economical ways of dental caries prevention is using fluoride containing toothpastes. For fluoride to be effective in toothpastes, significant amount of fluoride need to be in solution form. Global standard of fluoride content of toothpastes is 1500 ppm (part per million).This study aimed to determine fluoride content of some special toothpastes. Methods This research was...
