Bone fluorosis due to high water fluoride contents is endemic in North Africa. Neurological complications as spinal cord compression at dorsal level are rare and unusual. Its outcome depends on early diagnosis and surgical treatment. The authors report a new case of spinal cord compression due to ossification of the yellow vertebral ligament in a patient with previously unknown bone fluorosis.
PURPOSE The aim of this study was to evaluate micro-shear bond strength and morphological analysis of a self-etching primer adhesive system to fluorosed enamel. MATERIALS AND METHODS Extracted human molars were classified according to the severity of fluorosis using Thylstrup and Fejerskov index into four groups (TFI: 0, normal; 1-3, mild fluorosis; 3-6, moderate fluorosis; 6-7, severe fluoro...
The US Public Health Service has finalized its recommendation relating to community water fluoridation (Federal Panel on Community Water Fluoridation, US Department of Health and Human Services, 2015). It recommends an optimal concentration of 0.7 mg/l F based on their argument that this concentration provides the best balance of protection from dental caries while limiting the risk of dental f...
Choi et al. (2014) is a pilot study of the association of exposure to fluoride with cognitive function of children in a Chinese community. Although limited it provides more useful information than almost all the studies included in the earlier review by Choi et al. (2012). Most of the reports considered in that reviewwere very brief with little detail or consideration of confounding factors. Po...
Pre-eruptive enamel lesions occur during tooth formation and include fluorosis, traumatic hypomineralization, molar incisor hypomineralization. Minimally invasive treatment approaches, such as microabrasion, should be considered for these cases. This article presents a case series of three patients with pre-eruptive defects in esthetically compromised regions which were treated the microabrasio...
Water is the most vital natural resource for survival of human being and environment on earth surface. But Fluoride contamination water has become a widespread serious problem all over world including India. Supplying right amount fluoride to drinking protects teeth from decay reduces risk cavities. Exposure beyond recommended level longer duration causes both dental skeletal fluorosis. Health ...
Introduced to the commercial market 40 years ago, fluoride dentifrice now accounts for nearly all dentifrice purchased in the United States. During this same time, the prevalence and severity of dental caries has declined while dental fluorosis prevalence has increased. While the caries decline can be largely attributed to widespread fluoride dentifrice use, as well as many other sources of flu...
A PRELIMINARY report of a fluorosis survey carried out in Tanzania in East Africa was recently published.' That paper was designed mainly to report the high incidence of fluorotic bone changes in certain subjects and it constituted the first proof of naturally occurring bone fluorosis in this region of Africa. The present paper has been produced to give further details of the conduct and other ...
A survey was canted oat in two villages near Varanasi covering 2159 subjects. Dental mottling was observed in 24-91 per cent of the subjects but no case of skeletal fluorosis was detected. The prevalence of dental fluorosis was low in children below 5 yr of age but it sharply increased thereafter to a mn*imnm prevalence in the 11 to 15 yr age group. Among individuals beyond that age, there was ...
Decisions concerning use of fluoride in its many forms for caries prevention are more complicated now than in the past because of the need to balance these benefits with the risks of dental fluorosis. This article reviews pertinent literature concerning dental fluorosis (definition, appearance, prevalence), pre- and post-eruptive use of fluoride, esthetic perceptions of dental fluorosis, fluori...
