When acute exposure to fluoride is thought to be the cause of death, confirmation often depends on the analysis of some body fluid or tissue. The aim of this study was to evaluate the use of nails and the periosteal surface of bone as indicators of acute exposure to fluoride. Six groups of rats were given a single oral dose of fluoride (50 mg/kg body weight), while the control group was given d...

Fluoride-ion conducting solid materials are applicable as electrolytes for sensing devices and next-generation rechargeable batteries. Most of the previously reported have been limited to single-anion compounds such fluorite-type, tysonite-type, perovskite-type structures. These suffered from further improvements by crystal structure modification which derives a paradigm shift in material tailo...

Introduction: Glass ionomer cement (GIC) is a restorative material used in pediatric dentistry, which attaches to dental hard tissues and has cariostatic properties due to the ability for fluoride release. The present study aimed to assess the fluoride release and uptake capacity of two GICs in the presence of various fluoride sources. Methods: This in-vitro study was conducted on 120 disks com...

The range of fluoride levels in the drinking-water of cities and villages in South Africa was determined during the transition from a very dry (1983) to a wet (1984/85) period. The combination fluoride ion selective electrode was employed for the determination of the fluoride concentration. It was found that fluoride levels in drinking-water changed for 93% of the cities and villages studied du...

Background and Aim: Many studies have shown that various fluoride-containing products can change salivary fluoride concentration. Nowadays, different kinds of topical fluoride gels and foams are used to prevent dental caries. The aim of this study was to evaluate salivary fluoride concentration following the application of 3 different fluoride containing materials at different follow-up interva...

BACKGROUND The purpose of the study was to investigate the relationship between fluoride ions in drinking water and the incidence of dental fluorosis in some endemic areas of Bongo District, Ghana. METHOD Two hundred children were randomly selected from various homes and taken through a questionnaire. Their teeth were examined for the detection of dental fluorosis using the Dean's specific in...

Introduction & Objective: Tea is one of the most commonly consumed drinks in the world. Tea is recognized as a source of fluoride whose intake may increase the risk of developing dental fluorosis, particularly if other sources of fluoride augment the intake. Since the amount of fluoride in different types of tea consumed in our country is unknown, the purpose of this study was to evaluate the...

Uranium and fluoride are often found in combination in the nuclear power industry, where uranium hexafluoride is used to enrich uranium mixtures to increase the activity. Upon contact with moisture, including moisture in the air, uranium hexafluoride rapidly hydrolyzes to uranyl fluoride (UO2F2) and hydrogen fluoride. As these uranium compounds see heavy industrial use, many of the studies of t...
