A lthough recent data suggest that the incidence rate of dental caries has begun to decline dramatically in developed nations' Canadians still have a moderate to high rate of the disease.2 Fluoridation of communal water supplies is the most cost-effective measure to prevent dental caries; it reduces dental decay by 30% to 60% yet costs only about 15¢ per person per year.3 Unfortunately, only ab...

one common negative side effect of orthodontic treatment with fixed appliances is the development of incipient caries lesions around brackets, particularly in patients with poor oral hygiene. different methods have been used to prevent demineralization such as fluoride therapy and application of sealant to prevent caries. the recent effort to improve the resistance against the demineralization ...

statement of the problem generally, the main source of fluoride intake is drinking water. excessive consumption of bottled water as a substitute or in addition to the tap water supply may have implications for safe fluoride supplementation. in this study, fluoride contents in six commercial brands of bottled water were measured materials and methods six different brands of bottled drinking wate...

OBJECTIVE This in vitro study aimed to evaluate the effect of a low intensity diode laser (λ=808 nm; 60 J/cm2) associated with stannous fluoride on the inhibition of dentin erosion by assessing percentage of superficial hardness loss (%SHL) and calcium release into the acid solution. MATERIALS AND METHODS Human root dentin slabs were assigned to eight groups (n=10), according to treatments (c...

tea is the second most commonly consumed beverage world wide. tea ( camellia sinensis ) is a naturally rich source of fluoride. the quantity of fluoride intake is important in optimizing its dental caries-preventive role. intense concentration of fluoride in tea, can lead to excessive fluoride intake which may cause health problems in turn. the measurement of fluoride intake usually requires in...

calcium fluoride deposit during fluoride application. uptake and retention of fluoride by saliva depends generally on the concentration of calcium. in this study, the effect of calcium pre-rinse on salivary fluoride concentration after a 900 ppm fluoride mouthwash was investigated.this cross-over double-blind randomized clinical trial was conducted in a girls' dormitory in zahedan university of...

fluoride is one of the most important elements in the composition of teeth and bones. this element can enter the body via different ways. however, drinking water is the most important way to receive fluoride by a lot of people. an increase in fluoride level in the body causes dental fluorosis and its absence leads to teeth decay. standard rate of fluoride in drinking water is determined by the ...
