presence of available and stable fluoride in a dentifrice formulation is a major requirement for an anti-caries effect. although the available fluoride concentration in iranian dentifrices has been reported in previous studies, there is little information on its stability; which is dependent upon dentifrice formulation. this study was done to assess the fluoride ion concentration and stability ...

Urinary fluoride concentrations have been measured in electric arc welders using basic electrodes. The fluoride concentration and the total welding fume concentration in air showed a linear relation with postshift urinary fluoride concentration. The measured concentrations were below internationally recommended postshift urinary fluoride concentrations believed to cause fluorosis. Biological mo...

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...

The objective of the study was to evaluate the relationship between the fluoride concentration of the fluoride-releasing elastomers and the acquired acid resistance of human enamel. Four kinds of fluoride concentration of the experimental fluoride-releasing elastomers were 1.25, 2.5, 3.75 and 5.0 wt%. An enamel block was cut into two smaller enamel blocks, one of which was set with an elastomer...

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...

A study was performed to determine groundwater fluoride concentration of Posht-e-Kooh-eDashtestan area located in southern Iran. Groundwater samples were collected from 26 wells, 4 springs, during dry and wet seasons. Fluoride concentration was determined in the water samples using SPADNS method. The results showed that fluoride concentrations are above the World Health Organization (WHO) maxim...

This study aimed to preliminary investigate the role of activin receptor-like kinase (ALK) 5 as one of TGF-βR1 subtypes in bone turnover and osteoblastic differentiation induced by fluoride. We analyzed bone mineral density and the expression of genes related with transforming growth factor-β1(TGF-β1) signaling and bone turnover in rats treated by different concentrations of fluoride with or wi...

Background: The existence of fluoride ion in potable water has distinctive effects on human health. Fluoride is attracted by positively charged calcium in teeth and bones due to its strong electro-negativity which results in dental, skeletal, and non-skeletal forms of xuorosis and associated health complaints in children as well as adults. Methods: Water samples from groundwater used for dri...
