abstract statement of problem: dentin hypersensitivity is one of the most common complaints of patients after periodontal treatments which occur after tissue shrinkage. objectives: the aim of this study was to determine and compare the effectiveness of sensikin gel (10% potassium nitrate and 0.22% sodium fluoride) with sodium fluoride gel (2.7%) and fluoride varnish (5%) in reducing the dentin ...

Aim. The aim of the study was to determine whether three fluoride containing resin composites could maintain fluoride release, fluoride recharge, and mechanical stability over long-term (18-month) aging. Materials and Methods. Fluoride containing composites Beautifil II, Gradia Direct X, Tetric EvoCeram, and glass ionomer Fuji IX Extra were analyzed. Specimens of each material were fabricated f...

Prevention of peri-bracket decalcification is essentially mediated by effective oral hygiene, which is patient dependent. The potential to compensate for poor oral hygiene may be through the release of free fluoride ions from direct bonding agents. It is well established that glass ionomer cements (GICs) release free fluoride ions which may be replenished by exposure to fluoride containing solu...

Uranium and fluoride are often found in combination in the nuclear power industry, where uranium hexafluoride is used to enrich uranium mixtures to increase the activity. Upon contact with moisture, including moisture in the air, uranium hexafluoride rapidly hydrolyzes to uranyl fluoride (UO2F2) and hydrogen fluoride. As these uranium compounds see heavy industrial use, many of the studies of t...

presence of available and stable fluoride in a dentifrice formulation is a major requirement for an anti-caries effect. although the available fluoride concentration in iranian dentifrices has been reported in previous studies, there is little information on its stability; which is dependent upon dentifrice formulation. this study was done to assess the fluoride ion concentration and stability ...

Fluoride varnishes are fast becoming the standard of care as topical fluoride treatments. Fluoride varnishes still await approval from the FDA for use as caries preventive agents. In the meantime, their use for such purposes is considered "off-label." This article highlights the efficacy of fluoride varnishes as caries preventive agents and introduces some of the commercially available fluoride...

BACKGROUND Fluoride is used increasingly in a variety of industries in India. Emission of fluoride dust and fumes from the smelters of primary aluminum producing industries is dissipated in the work environment and poses occupational health hazards. OBJECTIVE To study the prevalence of health complaints and its association with fluoride level in body fluids of smelter workers in a primary alu...

Urinary fluoride concentrations have been measured in electric arc welders using basic electrodes. The fluoride concentration and the total welding fume concentration in air showed a linear relation with postshift urinary fluoride concentration. The measured concentrations were below internationally recommended postshift urinary fluoride concentrations believed to cause fluorosis. Biological mo...

The CSF fluoride level of individuals drinking water with normal fluoride content and of patients with endemic fluorosis were studied. For the purpose of studying the relationship between the dynamic equilibrium of the CSF fluoride and other body fluids, urine and blood fluoride were examined simultaneously. Fluoride was revealed in every CSF sample of the control group and its mean value was l...
