The aim of this study was to assess the prevalence and severity of dental fluorosis in permanent teeth and its association with dental caries in a group of school children living in a nonfluoridated community of Wielkopolska (Poland). The sample consisted of 470 children aged 6–14 years. Dental fluorosis was described using the Thylstrup and Fejerskov Index (TFI). Dental caries experience was a...

OBJECTIVE To determine the prevalence and severity of dental fluorosis, as well as factors associated with its occurrence, in seven cohorts of children before and after the implementation of a fluoridated salt program in 1991. MATERIAL AND METHODS A cross-sectional study was carried out in 1,373 children aged from 6 to 12 years in Campeche, Mexico. Data were collected by means of a questionna...

OBJECTIVES Several studies have focused on the timing of fluoride intake relative to the development of dental fluorosis. This study reports the relationships of fluoride intake during the first 48 months of life with fluorosis on early-erupting permanent teeth. METHODS Subjects were followed from birth to 48 months with questionnaires every 3-4 months. Questionnaires gathered data on intakes...

BACKGROUND AND AIMS Fluorosis is defined as a sort of enamel hypocalcification. Clinical features of fluorosis vary from thin white lines on the enamel to chalky and opaque enamel. The enamel may be destroyed after tooth eruption. Various prevalence rates have been reported in different populations. Major contributing factors are temperature, altitude and hygienic trends. The aim of this study ...

Brick tea skeletal fluorosis is still a public health issue in the north-western area of China. However its pathogenesis remains unknown. Our previous study reveals that the severity of skeletal fluorosis in Tibetans is more serious than that in Kazaks, although they have similar fluoride exposure, suggesting the onset of brick tea type skeletal fluorosis might be genetically influenced. Here w...

Brick tea-drinking fluorosis is an unusual environmental problem. As a result of an investigation of tea-drinking habits, total fluoride intakes, dental fluorosis, and skeletal fluorosis, this disease has been found in the Sichuan Province of China in Tibetans with a long history of drinking brick tea. The dental fluorosis investigation of 375 Tibetan children (213 males, 162 females) and 161 H...

Objectives : To study the epidemiology and estimate the prevalence of fluorosis in Cherlapally village of Nalgonda district. Materials and Methods : Descriptive, crosssectional study of the sample population of Cher...

OBJECTIVES We assess the prevalence and pathogenic stage of skeletal fluorosis among children and adolescents residing in a severe coal-burning endemic fluorosis area of southwest China. METHODS We used a cross-sectional design. A total of 1,616 students aged between 7 and 16 years in Zhijin County, Guizhou, China in late 2004 were selected via a cluster sampling of all 9-year compulsory educ...

CONTEXT Fluorosis is controlled by the duration of fluoride exposure and calcium and Vitamin D nutrition status. AIM To examine (a) prevalence of dental and skeletal fluorosis in adolescents from upper, middle, and lower socioeconomic strata (SES) and (b) association of fluorosis with calcium intake and Vitamin D status. SETTINGS AND DESIGN A cross-sectional study conducted in 10-13.9 years...
