Fluoride is recognized as an effective agent for dental caries prevention. Generally, the main source of fluoride intake is drinking water. In this study, fluoride content in 18 commercial brands of bottled waters was investigated. Six samples from each batch of 18 Iranian commercial brands of bottled waters were supplied. The fluoride content of samples was analyzed by Fluoride Ion Selective E...

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...

Background & Aims: The present study compared fluoride uptake into enamel from sodium fluoride 0.05% gel and American Dental Association approved fluoride gel (Stannous fluoride 0.4% , Sultan Co.) when used on healthy enamel of the intact teeth. Methods: In an experimental study, 30 intact teeth extracted for orthodontic purposes were randomly assigned into two groups of 15 teeth. The teeth wer...

background and aims. streptococcus mutans is the main pathogenic agent involved in dental caries, and may be eliminated using mouthwashes. the objective of this study was to compare the effects of fluoride, chlorhexidine, and fluoride-chlorhexidine mouthwashes on salivary s. mutans count after two weeks of use and determine the prevalence of their side effects on the oral mucosa. materials and ...

objectives: this study aimed to assess the self-reported knowledge and attitude of dentists towards fluoride prescription. materials and methods: a questionnaire survey was conducted at the national annual dental congress in 2010 in tehran-iran. dentists’ level of knowledge about the preventive effects of systemic and topical administration of fluoride was assessed as well as their attitudes to...

statement of problem: since the fluoride releases from materials with the property of releasing fluoride are decreasing gradually, it seems that probably the material rechargeability is more important than their long-term fluoride release. purpose: the objective of this study was to asses the fluoride release and rechargeability of 2 types of fluoride releasing restorative materials, a resin mo...

background; fluoride is an essential nutrient for the human body. the major routes of fluoride intake include food and drinking water, though the absorption of fluoride from food is much easier. the aim of this study was to evaluate the amount of fluoride in the soil and tomato and onion crops on farms of zanjan. methods; three farms of each crop (tomato and onion) were selected randomly. each ...

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...
