BACKGROUND In India, for the high concentration of fluoride in groundwater, people are at risk of dental fluorosis. The problem is common in various states of India. The condition in Rajasthan is worse where all districts have such a problem. OBJECTIVE To study the fluoride concentration in groundwater and prevalence of dental fluorosis in Didwana block of Nagaur district, Central Rajasthan, ...

BACKGROUND The purpose of the study was to investigate the relationship between fluoride ions in drinking water and the incidence of dental fluorosis in some endemic areas of Bongo District, Ghana. METHOD Two hundred children were randomly selected from various homes and taken through a questionnaire. Their teeth were examined for the detection of dental fluorosis using the Dean's specific in...

Several communities in Paraíba have moderate or high levels of fluoride naturally present in the drinking water. A moderate prevalence of dental fluorosis (30-40%) has been observed in some areas where the levels of fluoride are regarded as "optimal" for the region (0.6 ppm). The aim of the present study was to determine the prevalence of dental fluorosis in Princesa Isabel, a city with "sub-op...

The aim of this study was to assess agreement in the diagnosis of dental fluorosis performed by a standardized digital photographic method and a clinical examination (gold standard). 49 children (aged 7-9 years) were clinically evaluated by a trained examiner for the assessment of dental fluorosis. Central incisors were evaluated for the presence or absence of dental fluorosis and were photogra...

Objective: To identify adolescents' self-perception of dental fluorosis from two areas with different socioeconomic levels. Methods: A cross-sectional, descriptive study was conducted with 15-year-old youths by applying a questionnaire designed and validated to assess self-perceptions of dental fluorosis in two areas with different socioeconomic statuses (SESs). Fluorosis was clinically evaluat...

The purpose of this study was to assess the prevalence and severity of dental fluorosis in 513 primary school children in Nairobi. The clinical examination was performed in a room with natural daylight using Thylstrup & Fejerskov's index (TFI). Overall, 18% of 6-8-yr-olds had dental fluorosis in the primary dentition and 76% of 13-15-yr-olds in the permanent dentition. There was no significant ...

It is observational, analytical and cross-sectional aimed to evaluate the association between severity and prevalence of fluorosis and dental caries in rural communities with endemic dental fluorosis in the north state of Minas Gerais, Brazil, with fluoride concentrations in water up to 4.8 mg/L. Data were collected by one examiner (intra-examiner kappa, 0.96 to 0,95 for caries and fluorosis) a...

Flourosis is the result of fluoride rearranging the crystalline structure of a tooth's enamel as it is still growing. It is evidence of fluoride's potency and ability to cause physiologic changes within the body and raises concerns about similar damage that may be occurring in the bones. Fluoride causes dental fluorosis by damaging the enamel-forming cells, called ameloblasts. The damage to the...

The decline in dental caries prevalence and incidence in developed countries over the last two decades is considered to be largely due to the widespread use of fluoride. Simultaneously, with the decline in caries, an increase in the prevalence of dental fluorosis has been noticed. The increase is in the mild and very mild forms of fluorosis, and is proportionally greater in non-fluoridated area...

Objective. To explore the distribution of ER RsaI genotype in children who lived in the areas with or without high fluoride in drinking water, and investigate the relationship between ER gene RsaI polymorphisms and children’s dental fluorosis. Methods. We conducted a case-control study among children aged 8 to 12 years old with (n=74) or without (n = 163) dental fluorosis in two counties in Hen...
