OBJECTIVES The aim of this study was to determine the fluoride levels in breast milk and plasma of lactating mothers who regularly consumed drinking water with low levels of fluoride. METHODS One hundred twenty five healthy mothers aged between 20-30 years old who had given birth within 5-7 days were included in the study. Besides being otherwise healthy, the primary selection criteria stipul...

abstract background and purpose fluoride is one of the fundamental and required components in human body. the current study intends to survey the status of fluoride in drinking water supplies ( underground water source and drinking water) in qaemshahr city from 2006 (march/21) to 2012(march/19) and comparison with universal standards, national and climatic conditions. materials and methods this...

Background: Fluoride plays an important role in bone and dentin mineralization; however, excess fluoride intake is harmful to mankind. Methods: This study evaluated the performance of bauxite from active Iranian mines in removing fluoride from drinking water. The effects of pH, contact time, adsorbent dose, and fluoride concentration on defluoridation and removal efficiency were determined. Ki...

Fluoride in drinking water has a profound effect on teeth. Since drinking water is an important source of fluoride, the evaluation of the fluoride content of water resources is necessary. Temporal variations and spatial distribution of fluoride in drinking water of some selected parts of Kurdistan Province, Iran, have been studied using geographic information system (GIS) techniques. Thus, 40 v...

Fluoride is found in all water resources at different concentrations and drinking water is the major source of fluoride exposure. Thus, because of the adverse effect of fluoride in low and high concentrations, the evaluation of its content in drinking water is necessary. In the present study, the temporal variations and spatial distribution of fluoride concentrations in the drinking water of vi...

Introduction: It has been proved that sufficient amount of fluoride in drinking water can decrease the rate of dental caries. The aim of this study was to determine fluoride content of drinking waters in the 8 cities of Kerman province as well as 11 types of mineral water sold in supermarkets of Kerman. Method: Fluoride contents of 42 drinking water samples belonged to 8 cities of Kerman provin...

Effects of 5 kinds of fluorides on the twitch of the sartorius muscle of the bull frog were investigated. All of the fluorides (0.1-2.0 mM) enhanced the twitch evoked by nerve stimulation. The extents of enhancement at 2.0 mM were in the order: stannous fluoride much greater than potassium fluoride greater than sodium silico fluoride greater than sodium fluoride greater than diammine silver flu...

a flow injection system is reported for the determination of fluoride based on its effects on the fluorescence intensity of al-morin complex at ph 3.0 in ethanol-warn mixture. the effect of important parameters such as excitation and emission wavelengths, ph, reagents concenkations, flow rate of the carrier stream, sample injection volume, time of measurepent and interferences are reported. cat...

Aims: The first aim of this in vitro study was the comparative assessment of enamel surface morphology and analytical assessment of calcium and fluoride ions after topical application of three sodium fluoride solutions: solutions A and B having the same concentration (0.05% sodium fluoride) and solution C having a higher concentration (0.1% sodium fluoride). The second aim was to assess the rem...
