A EARLY as 1901, the condition now called dental fluorosis or mottled enamel was described in a letter written by J. M. Eager, a medical officer stationed in Naples, Italy, who reported its presence among Italian emigrants.' The term "mottled enamel" was first used by Dr. G. V. Black in a series of articles published jointly with Dr. Frederick S. McKay2'3 in which the lesions were described in ...
OBJECTIVE To determine the sources of fluoride exposure and the prevalence and severity of fluorosis and dental caries and sources of fluoride exposure in the permanent dentition of 11-year-old children. MATERIAL AND METHODS A cross-sectional study of 111 children attending elementary schools in the State of Mexico, where the concentration of fluoride in drinking water is < 0.3 ppm, was perfo...
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,...
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 To check knowledge of undergraduate dental students to make diagnosis of dental fluorosis with varying degrees of severity and choose its appropriate treatment. METHODS Data were collected using a semi-structured questionnaire addressing knowledge of undergraduates based on ten images of mouths presenting enamel changes. RESULTS Only three images were correctly diagnosed by most u...
This study evaluated the prevalence and severity of dental fluorosis and compared the reports from adolescents aged 12 to 18 years with those of their parents regarding the perceptions and concerns arising from this disease. The study was conducted in the cities of Viçosa and Sobral and the District of Rafael Arruda (Sobral), Ceará. A cross-sectional study was conducted from October 2010 to Mar...
OBJECTIVE The purpose of this study was to evaluate caries and dental fluorosis among Mexican preschoolers and school-aged children in a non-endemic zone for fluorosis and to measure its biological indicators. METHODS DMFT, DMFS, dmft, dmfs, and CDI indexes were applied. Fluoride urinary excretion and fluoride concentrations in home water, table salt, bottled water, bottled drinks, and toothp...
Skeletal fluorosis is one of a range of conditions causing excessive ossification and joint ankylosis in skeletons. It is rarely considered, however, in differential diagnoses of palaeopathological lesions. This paper considers the identification of skeletal fluorosis in a skeletal sample from the island of Bahrain, Arabian Gulf, dating to ca. 250 BC-AD 250. Approximately 4% of 255 adult skelet...
BACKGROUND To determine the severity of dental fluorosis in selected populations in Chiang Mai, Thailand with different exposures to fluoride and to explore possible risk indicators for dental fluorosis. METHODS Subjects were male and female lifetime residents aged 8-13 years. For each child the fluoride content of drinking and cooking water samples were assessed. Digital images were taken of...
