OBJECTIVES Several studies have focused on the timing of fluoride intake relative to the development of dental fluorosis. This study reports the relationships of fluoride intake during the first 48 months of life with fluorosis on early-erupting permanent teeth. METHODS Subjects were followed from birth to 48 months with questionnaires every 3-4 months. Questionnaires gathered data on intakes...

A Geographic Information System (GIS) coupled with environmental and health data was used for the study of human exposure to fluoride in the city of San Luis Potosi (SLP). The city was divided into four different risk areas. These areas were categorized according to fluoride levels in tap water, fluoride concentrations in well water and dental fluorosis prevalence in children. Fluoride levels i...

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 ...

Like many elements, fluorine (which generally occurs in nature as fluoride) is beneficial to human health in trace amounts, but can be toxic in excess. The links between low intakes of fluoride and dental protection are well known; however, fluoride is a powerful calcium-seeking element and can interfere with the calcified structure of bones and teeth in the human body at higher concentrations ...

The early use of fluoride dentifrice and use of larger quantities recently have been identified as risk factors for dental fluorosis. However, little is known about fluoride dentifrice use and ingestion among infants and young children whose developing permanent teeth are at risk for dental fluorosis. This paper reports on patterns of fluoride dentifrice use among a birth cohort up to 12 months...

Water is the most vital natural resource for survival of human being and environment on earth surface. But Fluoride contamination water has become a widespread serious problem all over world including India. Supplying right amount fluoride to drinking protects teeth from decay reduces risk cavities. Exposure beyond recommended level longer duration causes both dental skeletal fluorosis. Health ...

Dental fluorosis has recently been diagnosed in wild marsupials inhabiting a high-fluoride area in Victoria, Australia. Information on the histopathology of fluorotic marsupial enamel has thus far not been available. This study analyzed the developmental and post-eruptive defects in fluorotic molar enamel of eastern grey kangaroos (Macropus giganteus) from the same high-fluoride area using ligh...

The purpose of this study was to assess exposure to drinking water fluoride and evaluate the risk of dental fluorosis among the Estonian population. The study covered all 15 counties in Estonia and 93.7% of population that has access to public water supplies. In Estonia groundwater is the main source for public water supply systems in most towns and rural settlements. The content of natural flu...

AIM The aim of this study was to investigate the oral health status of children aged 6-12 years old living in the Danube Delta Biosphere Reserve. METHODS The entire population of 6-12-year-olds living in the Reserve was targeted. A cross-sectional study consisting of dental examinations based on World Health Organization (WHO) 1997 criteria was performed in 2011. Dental caries, periodontal (g...
