BACKGROUND The objective of the present study was to determine the prevalence and severity of dental fluorosis and to evaluate exposure to fluoridated products in students in the southwest part of the Federal District (Mexico City). MATERIAL AND METHODS Students between 10 and 12 years of age who were born and raised in the study zone were evaluated. The level of dental fluorosis was determined...

The prevalence of dental fluorosis in a nonfluoridated area was determined and related to the reported fluoride ingestion histories of the children examined. A convenience sample of 543 schoolchildren in rural areas of Michigan was examined for fluorosis using the Tooth Surface Index of Fluorosis. Questionnaires that asked about previous use of fluorides were sent to parents of all children exa...

AIM This was to determine the prevalence of primary tooth fluorosis in the dentitions of 5-year-old schoolchildren. A subsidiary aim was to investigate whether an association existed between the presence of primary tooth fluorosis, fluoridation status, infant feeding practices or the oral hygiene practices of the child. STUDY DESIGN A cross-sectional and stratified by fluoridation status stud...

Several national studies have been undertaken to assess the prevalence of fluorosis utilizing the Dean's Index. However, the latest national study undertaken in 1997 (1) had utilized the DDE Index and hence does not allow comparisons to be made with the earlier set of national data. This cross-sectional study was undertaken to evaluate the prevalence of dental fluorosis using the Dean's Index i...

The aim of this study was to verify the prevalence of dental fluorosis in schoolchildren aged 6 to 15 and its possible association with the impacts on their daily activities. This study is observational, cross-sectional and analytical. A total of 513 schoolchildren from the city of Pinheiro Preto, SC, took part in this study. The children were examined by three calibrated dentists, after obtain...

OBJECTIVE This study was aimed at determining dental fluorosis prevalence and severity amongst 6-13-year-old students residing in Medellin, Colombia. METHODS A descriptive study was carried out on 1,330 students attending 34 public schools in the city of Medellin. Two dentists trained in dental fluorosis diagnosis performed the examinations were after the teeth had been brushed. Teeth were dr...

PURPOSE This study investigated the potential association between fluoride exposure and behavior problems in children, as well as the prevalence of and risk factors for fluorosis. METHODS Children between the ages of 7 and 1 years (N = 197) were included in the study and were examined for dental fluorosis using the Modified Dean's Index. Parents of subjects completed and returned three questi...

OBJECTIVE Very few studies have examined the relationship between timing of fluoride intake and development of dental fluorosis on late-erupting permanent teeth using period-specific fluoride intake information. This study examined this relationship using longitudinal fluoride intake information from the Iowa Fluoride Study. METHODS Participants' fluoride exposure and intake (birth to 10 year...

Dental fluorosis refers to changes in the appearance of tooth enamel that are caused by long-term ingestion of fluoride during the time teeth are forming. Studies conducted in the 1930s showed that the severity of tooth decay was lower and dental fluorosis was higher in areas with more fluoride in the drinking water. In response to these findings, community water fluoridation programs were deve...

OBJECTIVE To screen environmental response genes related to dental fluorosis, and to provide clues for further researches of the molecular mechanism of fluorosis. METHODS The leukocyte gene expression profiles of control group, high-loaded fluoride group and dental fluorosis group were tested using the gene chiR HG-U133A from Affymetrix company. The results were analyzed by bioinformatical me...
