The prevalence of dental fluorosis is on the increase in different parts of
the world, even in areas with fluoride-deficient public water supplies. Th
is may be due to increased use of fluoride in preventive dentistry. In some
countries, exposure to apparently low fluoride concentrations in drinking
water has resulted in severe dental fluorosis in some children. This unders
cores the importance of taking into consideration all sources of fluoride i
ntake in a community before prescribing fluoride supplements or recommendin
g appropriate fluoride concentration for the public water supply. Preventiv
e management of dental fluorosis includes de-fluoridation of drinking water
in endemic areas, cautious use of fluoride supplements and supervision of
the use of fluoride toothpaste by children aged below 5 years. Aestheticall
y objectionable discolouration of fluorosed teeth may be managed by bleachi
ng, micro-abrasion, veneering or crowning. The choice between these treatme
nts depends on the severity of the fluorosis and this may be satisfactorily
determined by the Thylstrup and Fejerskov index.
