INTRODUCTION Over the last two decades, the prevalence of dental caries in children has decreased and the prevalence of dental fluorosis has increased. Knowledge on the epidemiologic conditions of a population is fundamental for the planning of health programs. OBJECTIVES To determine the prevalence of dental caries and dental fluorosis among schoolchildren, in Catalão, Goiás, Brazil. METHO...

The study was undertaken to determine serum/urinary fluoride status and comparison of free T4, free T3 and thyroid stimulating hormone levels of 8 to 15 years old children with and without dental fluorosis living in an endemic and non-endemic fluorosis area. A sample group of 60 male and female school children, with or without dental fluorosis, consuming fluoride-contaminated water in endemic f...

AIM To estimate the prevalence of dental fluorosis in relation with different fluoride levels in drinking water among school going children of 6-12 years age group. MATERIALS AND METHODS Dental fluorosis was recorded using Dean's index in school children of selected villages. The drinking water samples of all the selected villages were collected in polyethylene bottles and the fluoride conten...

A high prevalence of dental fluorosis has been identified among children in the Gaza Strip. This study aimed to determine the history of breastfeeding and dietary behaviours among children in the Gaza Strip and to examine potential associations with the prevalence and severity of dental fluorosis. A cross-sectional study recruited a stratified cluster random sample of 350 children aged 12-18 ye...

UNLABELLED Aesthetic perception of the changes in teeth appearance is one of the factors that makes a person undertake a dental treatment. OBJECTIVE The aim of this study was to survey dentists' and non-specialists' aesthetic perception of dental fluorosis. PATIENTS AND METHODS We recruited 120 young people (age range 18-22 years with little knowledge of dental fluorosis and 120 randomly se...

This study aimed to validate the Child's and Parent's Questionnaire about Teeth Appearance and to evaluate concerns relative to fluorosis among 213 pairs of parents and 12-year-old children from two regions of Brazil. Reliability was assessed by Cronbach's alpha and intraclass correlation coefficient, and construct and criterion validity by Spearman's correlations. Student t-test was used to co...

OBJECTIVE Apart from its well-known deleterious dental and skeletal effects, fluoride excess can have toxic effects on many other tissues. Fluoride, when in excess, is known to interfere with thyroid gland function. Fluoride-induced thyroid disturbances similar to those observed in iodine deficiency state in spite of adequate iodine intake have been documented. Similar thyroid disturbances in i...

BACKGROUND The quantification of fluorosis using fluorescence imaging (QLF) hardware and stain analysis software has been demonstrated in selected populations with good correlation between fluorescent image metrics and TF Index scores from photographs. The aim of this study was to evaluate the ability of QLF to quantify fluorosis in a population of subjects (aged 11-13) participating in an epid...

OBJECTIVE There has been a worrisome increase in the prevalence of dental fluorosis worldwide. The objective of this study was to review research on dental fluorosis prevalence in Mexico in order to assess if that prevalence is rising and if dental fluorosis constitutes a public health problem for the country. METHODS Clinical, experimental, and review reports were searched for in a number of...

OBJECTIVE To explore the association between fluoride in drinking water and the prevalence and severity of fluorosis and dental caries in children living in communities receiving fluoridated salt. MATERIAL AND METHODS Participants were schoolchildren (n = 457) living in two rural areas of the State of Morelos, Mexico, where the water fluoride concentration was 0.70 or 1.50 ppm. Dental caries ...
