Background and purpose: Fluoride is one of the drinking water contaminants regulated by EPA. This ion, in low doses in the mouth reduces tooth decay without health risk and at much higher doses causes health complications and can be toxic. The major sources of exposure to fluoride are drinking water, food, dental products, and pesticides. The biggest contributor to exposure for most people in I...

Fluoride retention is high during fluoride supplementation and increases with increasing fluoride intake. When large amounts of fluoride were given for several months the retention of fluoride was about the same as in the initial phase of fluoride supplementation, whether the supplemental dose of fluoride was 10, 20, or 45 mg per day. The rapid return of the fluoride balance to control values...

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 drinki...

The aim of this investigation was to determine the influence of fluoride in certain mouthwashes on the risk of corrosion through galvanic coupling of orthodontic wires and brackets. Two titanium alloy wires, nickel-titanium (NiTi) and copper-nickel-titanium (CuNiTi), and the three most commonly used brackets, titanium (Ti), iron-chromium-nickel (FeCrNi) and cobalt-chromium (CoCr), were tested i...

BACKGROUND AND OVERVIEW Dental caries is a bacterially based disease. When it progresses, acid produced by bacterial action on dietary fermentable carbohydrates diffuses into the tooth and dissolves the carbonated hydroxyapatite mineral--a process called demineralization. Pathological factors including acidogenic bacteria (mutans streptococci and lactobacilli), salivary dysfunction, and dietary...

INTRODUCTION Reliable animal models are required to evaluate novel treatments for osteosarcoma. In this study, the aim was to implement advanced imaging techniques in a murine model of orthotopic osteosarcoma to improve disease modeling and the assessment of primary and metastatic disease. MATERIALS AND METHODS Intra-tibial injection of luciferase-tagged OPGR80 murine osteosarcoma cells was p...

Previous reports found that some fluoride-containing dentifrices do not release effective concentrations of fluoride during brushing. Failure to release fluoride can be due to dentifrice matrix components that interfere with the solubilization of the fluoride salts during brushing. A new generation of dentifrices has the capability to precipitate beneficial fluoride salts during tooth brushing....

A large number of Indians are forced to consume fluoride contaminated water. Toxic effects of chronic fluoride ingestion are hitherto considered irreversible. In this study 20 children were selected from an area consuming water containing 4.5 ppm of fluoride (Group A) and a second sample of 20 children from another area consuming water containing 8.5 ppm of fluoride (Group B). All the children ...
