F luoride varnish is a valuable tool in the prevention of tooth decay. Studies have demonstrated its effectiveness at arresting early cavitated lesions, remineralizing interproximal incipient smooth surface lesions and preventing caries. Medical personnel in many public health clinics now are applying these varnishes in an attempt to minimize treatment needs and reduce accessto-care problems. S...

This paper describes novel and innovative amorphous calcium magnesium fluoride phosphate (ACMFP) core-shell microparticles that may be applied in preventive dentistry for the prevention of caries treatment dentin hypersensitivity. The particles can synthesized with varied content, up to approximately 6 wt%, without any observable differences morphology or crystallinity. Fluoride release from is...

This in vitro study was undertaken to evaluate the caries-preventive effect of three orthodontic band cements (a dual-curing resinmodified glass ionomer cement [RMGIC] and two light-curing polyacid-modified composite resin [compomer] cements) in terms of fluoride release, retentiveness, and microleakage after thermocycling. The RMGIC (Ortholy Band Paste [GC Ortholy, Inc., Tokyo, Japan]) showed ...

12 13 The removal of fluoride using red mud has been improved by acidifying red mud with 14 hydrochloric, nitric and sulphuric acid. This investigation shows that the removal of fluoride 15 using red mud is significantly improved if red mud is initially acidified. The acidification of 16 red mud causes sodalite and cancrinite phases to dissociate, confirmed by the release of 17 sodium and alumi...

In 1983, Wilkinson (5) acknowledged that: ‘If the claim presented in court was correct, then fluoride in water would present a hazard to health as those drinking the water would be at risk from bacterial infections.’ He studied the effect of NaF on the locomotion and chemotaxis of human neutrophils and monocytes, using a microphore filter assay and a time-lapse photographic assay, and found tha...

Fluoride varnishes, both the first and second generations, are effective in inhibiting caries, especially children adolescents, by reducing it on average 43% for permanent teeth 37% deciduous teeth. The aim of this study was to evaluate dynamics vitro fluoride ion release from first- (Duraphat) second-generation (MI Varnish Embrace Varnish) varnishes impact type varnish, time its application pH...

Glass ionomer cement systems have become important dental restorative and luting materials for use in preschoolers, children and teenagers. These materials form chemical bonds to tooth structure, are biocompatible, release fluoride ions for uptake by enamel and dentin, and are able to take up fluoride ions from dentifrices, mouthwashes, and topically applied solutions. Unlike early glass ionome...

Glass-ionomer cements (GICs) are mainstream restorative materials that are bioactive and have a wide range of uses, such as lining, bonding, sealing, luting or restoring a tooth. Although the major characteristics of GICs for the wider applications in dentistry are adhesion to tooth structure, fluoride releasing capacity and tooth-colored restorations, the sensitivity to moisture, inherent opac...

The detection, differentiation and visualization of compounds such as gases, liquids or ions are key challenges for the design of selective optical chemosensors. Optical chemical sensors employ a transduction mechanism that converts a specific analyte recognition event into an optical signal. Here we report a novel concept for fluoride ion sensing where a porous crystalline framework serves as ...

Release of the protein molecule, leukocytic pyrogen, is one of the many reactions exhibited by leukocytes after phagocytosis. After the ingestion of heat-killed S. albus, a 3-4 hr latent period exists, during which human peripheral leukocytes release no pyrogen, yet cellular metabolism is altered in such a way that pyrogen output may subsequently occur in the absence of further phagocytosis. Tr...
