With the aims of determining the prevalence dental fluorosis in the city of Aracaju, Sergipe State, 196 students were submitted to an oral exam, utilizing the Dean's index. It was concluded that the prevalence of dental fluorosis in students ranging from 5 to 15 years old in the city of Aracaju, Sergipe State was of 8.16%, not implying in a risk to public health. However, similar studies must b...

some children of borazjan area have minute white flecks, yellow or brown spot areas scattered irregularly over the tooth surface, the causative factor was attributed to excess of fluoride in water. to verify this matter short chemical examination of water samples from endemic area was carried out. the results of water analysis by colorimetric method, using zirconium a1izarin reagent after disti...

objectives: this study aimed to determine the effect of surface treatments such as tooth reduction and extending the etching time on microtensile bond strength (µtbs) of composite resin to normal and fluorotic enamel after microabrasion. materials and methods: fifty non-carious anterior teeth were classified into two groups of normal and fluorotic (n=25) using thylstrup and fejerskov index (tfi...

OBJECTIVE The aim of this study is to investigate urine fluoride concentration as a toxicity factor in a rural community in the state of San Luis Potosi, Mexico. MATERIALS AND METHODS A sample of 111 children exposed to high concentrations of fluoride in drinking water (4.13 mg/L) was evaluated. Fluoride exposure was determined by measuring urine fluoride concentration using the potentiometri...

Background. The inconsistent prevalence of fluorosis for a given level of fluoride in drinking water suggests developmental defects of enamel (DDEs) other than fluorosis were being misdiagnosed as fluorosis. The imprecise definition and subjective perception of fluorosis indices could result in misdiagnosis of dental fluorosis. This study was conducted to distinguish genuine fluorosis from fluo...

BACKGROUND It has been speculated that amoxicillin use could be associated with dental enamel defects. OBJECTIVE To assess the association between dental fluorosis, one of the most common developmental tooth enamel defects, and amoxicillin use during early childhood. DESIGN, SETTING, AND PARTICIPANTS As participants in the Iowa Fluoride Study, subjects were followed up from birth to 32 mont...

This paper describes the first national survey of oral health in the United Arab Emirates (UAE). Using WHO criteria, dental caries and fluorosis were recorded in 2651 schoolchildren aged 12 and 15 years, and periodontal disease in those aged 15 years. The prevalence of dental caries in the permanent teeth of 12-year-olds was 54%; the mean DMFT (number of decayed, missing or filled permanent tee...

OBJECTIVES To determine the experience, prevalence, and severity of dental caries in adolescents naturally exposed to various fluoride concentrations. METHODS A cross-sectional census was conducted on 1,538 adolescents aged 12 and 15 years living at high altitude above sea level (> 2,000 m or > 6,560 ft) in above-optimal fluoridated communities (levels ranging from 1.38 to 3.07 ppm) of Hidalg...
