Spatial uncertainty caused by large-scale variation in fluoride (F?) occurrence remains a setback for water supply authorities the F? belts of world. It is estimated that approximately 80 million people East African Rift Valley (EARV) regions and volcanic areas exhibit wide variety fluorosis symptoms due to drinking with F? concentrations higher than 1.5 mg/L (WHO guideline limit). In this stud...

The aim of this study was to determine the prevalence and severity of dental fluorosis among 12-15-year-old students from João Pessoa, PB, Brazil before starting a program of artificial fluoridation of drinking water. The use of fluoridated dentifrice was also surveyed. A sample of 1,402 students was randomly selected. However, 31 students refused to participate and 257 were not permanent resid...

OBJECTIVE This investigation assessed two methods for estimating epidemiologic indicators of oral health status among children: (1) a visual-only screening, performed independently by a dental hygienist and a registered nurse; and (2) a parent- or guardian-completed questionnaire. The indicators included dichotomous variables measuring dental caries and treatment needs, presence of sealants, in...

OBJECTIVES The objectives of this study were to assess the fluoride concentration in the public water supply and the prevalence of dental fluorosis in schoolchildren between 7 and 15 years old, living in a peripheral district of the municipality of Bauru. MATERIAL AND METHODS For this, fifty two water samples were collected on three different days of one week. These samples were analyzed for ...

In the rural areas of India, fluoridated drinking water, industrial fluoride pollution and fluoride-rich feed phosphate supplements are major sources exposure for domesticated water buffaloes (Bubalus bubalis). However, groundwater is commonest principal source these ruminants. Chronic long-time deteriorate animal health causes fluorosis disease. country, villages contaminated with beyond thres...

STATEMENT OF PROBLEM The concentration of fluoride in water is usually higher in areas around the coal mines. Zarand region in the south-east of Iran is known for its coal mines. Some studies have shown the high prevalence of fluorosis and some studies reported high levels of fluoride in the region. OBJECTIVES This study aimed to use Geographic Information System (GIS) to assess the relations...

The fluoride concentration analyses were performed using the SPADNS method according to standard for examining and wastewater. range 0.35–3.46 mg/L sources. Notably, with high above World Health Organization (WHO) guideline observed Tumu-2 (2.88 mg/L), Lapan (3.46 Jalingo (1.79 Kaleh (...

OBJECTIVE To assess the prevalence and type of fluorosis among children from randomly selected villages of Chhattisgarh, and its relationship with fluoride levels in drinking water. METHODS A community based door-to-door survey was conducted in the sampled villages of seven districts of Chhattisgarh state during the year 2013-14. The field case definitions were used for labelling types of flu...

An epidemiological survey carried out in a village of Mandla district of Madhya Pradesh revealed a high prevalence of genu valgum(51.1%) and dental fluorosis (74.4%) among the children below 20 years. Notably, 16.3% children below 10 years were affected and fluorosis was documented with deep bore well water (more than 43 meters deep) consumption. However, it is generally believed that supply of...

Toothpaste can be used as a vehicle for substances to improve the oral health of individuals and populations. Therefore, it should be recommended based on the best scientific evidence available, and not on the opinion of authorities or specialists. Fluoride is the most important therapeutic substance used in toothpastes, adding to the effect of mechanical toothbrushing on dental caries control....
