Fluoridated mouthrinses are not advised for preschool children who may swallow much of the agent. An alternate method of delivering topical fluoride to the interproximal tooth surfaces in these young patients may be fluoridated dental floss. The purpose of this study was to determine the fluoride levels of demineralized primary enamel both before and after the use of a commercially available de...

Two pyrene dimers containing an -O-Si-Si-O- or -O-Si-O- linkage have been designed which exhibit ratiometric excimer/monomer emission upon fluoride anion induced Si-O bond cleavage. Incorporation of the probe into water soluble polymeric nanoparticles enhances its intracellular uptake and displays ratiometric fluorescent sensing for F(-) in living cells.

The purpose of this investigation was to study the intra-oral rehardening of acid-softened enamel and fluoride uptake from SnF2 gel. Bovine enamel slabs were softened with 0.1 mol/L lactate buffer at pH 4.0 for 14 hrs and then mounted in a mandibular removable Hawley appliance. Control slabs were worn for 96 hrs by seven adult males whose teeth were brushed daily with a fluoride-free dentifrice...

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...

BACKGROUND Voriconazole is a triazole antifungal medication used for prophylaxis or to treat invasive fungal infections. Inflammation of the periosteum resulting in skeletal pain, known as periostitis, is a reported side effect of long-term voriconazole therapy. The trifluorinated molecular structure of voriconazole suggests a possible link between excess fluoride and periostitis, as elevated b...

Background and purpose - [18F]Fluoride ([18F]NaF) PET scan is frequently used for estimation of bone healing rate and extent in cases of bone allografting and fracture healing. Some authors claim that [18F]NaF uptake is a measure of osteoblastic activity, calcium metabolism, or bone turnover. Based on the known affinity of fluoride to hydroxyapatite, we challenged this view. Methods - 10 male r...

BACKGROUND AND PURPOSE One concern regarding resurfacing arthroplasty is the viability of the diminished femoral head and the postoperative risk of collapse, or a femoral neck fracture. (18)F-fluoride positron emission tomography (F-PET) enables us to assess bone viability despite there being a covering metal component. By F-PET studies, we recently showed the absence of metabolism in the remai...

Fluoride is a key dentifrice ingredient for mitigating dental erosion and promoting remineralisation in tooth enamel. A formulation (NaF/CL - where C = Copolymer, L Lactate), optimised fluoride delivery, containing sodium fluoride, polyvinylmethylether–maleic anhydride (PVM/MA) copolymer lactate ion at controlled pH of 6.2 compared with six commercial dentifrices from European US regulatory reg...

This work was aimed to explore the efficacy of activated charcoal (5 mg g-1 soil) in abating fluoride (25 L-1 NaF) stress rice seedlings, since protective role is widely reported against other forms abiotic stress. Application NaF solution reduced germination rate, dry and fresh weight, shoot root length seedlings. Extensive accumulation lowered chlorophyll level along with higher electrolyte l...
