BACKGROUND Fluoride is an essential element for human health. However, excess fluoride in drinking water may cause dental and/or skeletal fluorosis. Drinking water is the main route of fluoride intake. The aim of the present study was to measure fluoride levels in human breast milk collected from two regions of Golestan Province, northern Iran with different amount of fluoride concentration of ...

Fluoride dentifrice has been accepted widely for use in caries prevention and its effectiveness has been confirmed. In order to enable the use of fluoride dentifrice effectively in daily brushing, the present study was performed to examine the relationship between fluoride uptake and the amount of fluoride dentifrice used and brushing time for adults. We examined the relationship between fluori...

BACKGROUND AND OBJECTIVE Previous reports of the reduction of fluoride concentrations in fluoridated water by domestic water treatment systems have indicated that further supplementation with fluoride is required. However, the absorption of fluoride by filters has not yet been directly identified. If these filters do not absorb fluoride, further fluoride supplementation may increase fluorosis. ...

Introduction: Exposure to high concentrations of fluoride in drinking water can negatively affect lung, liver and kidney tissues, and cause skeleton pain; however, lack of fluoride can cause tooth decay and bone problems. Materials and Methods: In this study, the concentration of fluoride was investigated and its spatial distribution was carried out with Arc GIS software in underground water o...

AIM The aim of the present study was to evaluate the relationship of drinking water fluoride levels with children's intelligence quotient (IQ). MATERIALS AND METHODS Water was collected from initially identified endemic fluoride regions according to the geological research of Government of India. Fluoride concentration of the water was assessed by utilizing fluoride ion selective electrode, O...

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 ...

AIM To provide a comprehensive report of fluoride concentration in UK infant milks and estimate their contribution to daily fluoride intake. METHODS A total of 60 formula milk products available commercially or within a hospital environment were analysed, along with eight pasteurised cow's milk samples. Formula milk products requiring preparation were reconstituted with fresh Leeds tap water ...
