Fluoride dentifrice has been accepted widely for use in caries prevention and its effectiveness has been confirmed. In order to enable the use of fluoride dentifrice effectively in daily brushing, the present study was performed to examine the relationship between fluoride uptake and the amount of fluoride dentifrice used and brushing time for adults. We examined the relationship between fluori...

UNLABELLED The aim of this study was to examine the prevalence, distribution, and topographic relationship of vascular (18)F-sodium fluoride uptake and arterial calcification in major arteries. METHODS Image data obtained from 75 patients undergoing whole-body (18)F-sodium fluoride PET/CT were evaluated retrospectively. Arterial radiotracer uptake and calcification were analyzed qualitatively...

OBJECTIVES Fluoride therapy is important for control and prevention of dental caries. Laser irradiation can increase fluoride uptake especially when combined with topical fluoride application. The objective of this study was to compare the effects of CO2 and diode lasers on enamel fluoride uptake in primary teeth. MATERIALS AND METHODS Forty human primary molars were randomly assigned to four...

Adsorption is one important technique in fluoride removal from aqueous solutions. The viability of adsorption techniques is greatly dependent on the development of adsorptive materials. A large number of materials have been tested at a fluoride concentration greater than 2 mg/l, and the lowest limit for fluoride reduction by them is about 2 mg/l. Decreasing the fluoride concentration to less th...

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...

Suckling rat pups were given intraperitoneal fluoride injections at selected ages so that we could study fluoride uptake in the enamel of the maxillary first molar at various stages of enamel development. Plasma fluoride levels in six-day-old and 11-day-old pups were monitored following the intraperitoneal injection of fluoride. The findings indicate that: (1) fluoride was more easily taken up ...

Background 18F-fluoride Positron Emission Tomography (fluoride-PET) is a functional imaging technique that mainly detects the acceleration of bone metabolism. We previously demonstrated the usefulness of fluoride-PET in various stages of hip osteoarthritis. Interestingly, the uptake was recognized even in the case without marked radipgraphical findings. The significant uptake in fluoride-PET in...

This study evaluated the effect of sealants on enamel demineralization, focusing on physical protection of the sealed enamel and fluoride protection of the adjacent unsealed enamel. Occlusal fissures with areas measuring 12 mm2 were delimited in 48 extracted molars, randomly divided into 4 groups (n =12): 1) no sealing; 2) sealing with a resin-modified glass-ionomer (Vitremer, 3M ESPE); 3) seal...

OBJECTIVE To determine the association between KOH-soluble and structurally bound fluoride uptake and the erosion resistance of enamel, respectively. Additionally, the effect of enamel pre-treatment with ethanol before fluoridation was assessed. METHODS Sixty bovine incisors (4 specimens/tooth) were randomly allocated to six groups (A-F). Samples 1 and 2 remained untreated, serving as control...

Fresh water crab was exposed in fluoride water at 96h the rate of oxygen uptake was higher in gills followed by hepatopancreas and muscle. On exposure to fluoride water, tissue respiratory rates decreased, effect on gill tissue appeared to be more pronounced than other tissues under the study. The rate of oxygen uptake in male was higher tha control animal. Rate of oxygen consumption showed a s...
