The use of bottled drinking water may be a source of fluoride and could be a risk factor for fluorosis among infants and young children. The aim of this study was to evaluate the fluoride content of commercially available bottled drinking water in Bangkok, Thailand. Forty-five water samples (15 samples of plain water and 30 samples of mineral water) were purchased from several supermarkets in B...

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...

Background and Purpose: Fluoride is a natural element essential for human nutrition due to its  benefits for dental enamel. It is well-documented that standard amounts of fluoride in drinkingwater can decrease the rate of dental caries. This study was conducted with the aim of measuring fluoride concentration of drinking-water supplies and urban distribution system in Qom, I...

&nbsp; Background : Fluorine is an essential micronutrient for human health, serving to strengthen the apatite matrix of skeletal tissues and teeth. In regions where the fluoride (F&minus;) concentration of water is naturally low (<0.5 mg/l), some communities have chosen to add this constituent to their drinking water to strengthen teeth and to minimize cavities P.B. Maithani, R. Gurjar, R. Ban...

Fluoride is now accessible in a variety of forms, including water, toothpaste, mouth rinses, and professional fluoride therapy at dental clinics. A body of data supports the use of systemic and topical fluoride from various sources to prevent dental caries. Fluoride ions are absorbed by the enamel prior to tooth eruption and produce fluorohydroxyapatite, which is more resistant to acid attack t...
