long-term exposure to high concentrations of fluoride is associated with several adverse effects on human including dental and skeletal fluorosis. we studied all the groundwater wells located in rural areas of khaf city, razavi province, northeastern iran between 2009 and 2010. fluoride concentration of water samples was measured by spadns method. we found that in rural areas the fluoride conce...
MicrosoftInternetExplorer4 Background and Objectives: Intake of high concentrations of fluoride in drinking water can cause dental fluorosis. In this study, the prevalence of dental fluorosis in rural communities of East Azerbaijan Province was studied. Materials and Methods: 3 villages of Bashsizkooh, Bostanabad (fluoride concentration in drinking water = 0.12 mg/L), Nagharehkub, Ahar ...
Fluoride is one of the few chemicals of natural origin that have been shown to cause significant health effects in people through drinking-water. The association between the fluoride level in drinking water and the degree of dental fluorosis has been documented worldwide. The permissible maximum health-based fluoride limit in drinking water is 1.5 mg/l. The aim of this paper is to assess human ...
Fluorosis induced by exposure to high level fluoride is quite widespread in the world. The manifestations of fluorosis include dental mottling, bone damage, and impaired malfunction of soft tissues. However, the molecular mechanism of fluorosis has not been clarified until now. To explore the underlying mechanisms of fluorosis and screen out serum biomarkers, we carried out a quantitative prote...
The authors have presented a technique of full occlusal rehabilitation in a case of severe dental fluorosis. In this technique, maxillary and mandibular anterior teeth were simultaneously prepared and restored first. This was followed by simultaneous preparation of maxillary and mandibular posterior teeth that were restored in canine guided occlusion. The technique and sequence followed here is...
The aim of the present study was to compare the values of the Thylstrup & Fejerskov Index (TF index) for the determination of the prevalence of dental fluorosis using either all teeth (gold standard) or six upper anterior teeth (simplified TF index). The sample was made up of 396 individuals aged six to 22 years from three Brazilian cities with endemic fluorosis caused by the ingestion of water...
It has been suggested that psychosocial dimensions be used to assess the impact of oral health on people's quality of life. The purpose of this study was to measure the impact of dental caries and dental fluorosis on children's self-perception of appearance and mastication. A dental caries and dental fluorosis cross-sectional study was conducted with twelve-year-old schoolchildren (n = 695) in ...
background. regarding the lack of comprehensive systematic review on the efficacy of water fluoridation and prevalence of dental fluorosis, the aim of the current research was to systematically study the prevalence of dental fluorosis at different levels of water fluoride in the world and lay emphasis on the amount of fluoride in drinking water. methods. studies were searched in pubmed, scopus,...
conclusions the fluoride content of drinking water in reservoirs and at homes was below the optimal level in mariwan. no differences were observed from the standard levels in behbahan. there were no differences in fluoride content of water in reservoirs and in home pipelines, indicating no tangible changes in fluoride content from the reservoirs to the homes. in neither of the towns was severe ...
Ingestion of fluoride dentifrice by preschool children recently has been implicated as a risk factor for dental fluorosis. The availability of dentifrices flavored for children could increase fluoride ingestion by young children at risk for dental fluorosis. This article reports results of a pilot study of use of regular-flavored dentifrice and those flavored for children among 29 preschool chi...
