the efficacy of correctly applied fissure sealants has been revealed in the prevention of caries. saliva and moisture contamination of the etched enamel surface before sealant placement can decrease the bonding strength of the sealant to the enamel. the aim of this study was to test the new bonding agents containing nano-fillers in order to reduce the negative effect of saliva contamination on ...

in this study, the removal of cadmium and lead ions from aqueous solution by nanocrystalline magnetite was investigated. the nanocrystalline magnetite was synthesized by mechanochemical activation of hematite in a high energy planetary mill in argon atmosphere for 45 hours. the ability of the synthesized nanocrystalline magnetite for removal of cd(ii) and pb(ii) from aqueous solutions was studi...

Introduction: Tobacco smoke is involved in the pathogenesis of several diseases in different body systems. Saliva is the first body fluid that confront inhaled cigarette smoke which is injurious to the oral cavity and is associated with several oral diseases and cancer. The aim of our study was to evaluate the influence of smoking on the activity of alpha-amylase in the saliva of healthy smoker...

Oral diseases associated with systematic diseases as metabolic and vasculitic have been included in this paper. This will enhance our understanding of the salivary function in promoting healthy oral condition. The study investigates the effects of type I and type II diabetes mellitus in well-controlled diabetic patients, in addition to Behçet disease (BD) on saliva flow rate (SFR), pH, the deca...

OBJECTIVES As the choice of suprastructure alloy to be combined with titanium for the oral cavity is still a much debated issue, the aim of this study was to investigate the electrochemical interaction of the suprastructure/implant couples under the determined experiment conditions. MATERIAL AND METHODS The potentiodynamic polarization curves and open-circuit potentials (OCP) of four UCLA typ...

OBJECTIVE To reduce secondary caries, glass ionomer luting cements are often used for cementing of indirect restorations. This is because of their well-known antimicrobial potential through the release of fluoride ions. The aim of this in vitro study was to investigate the antimicrobial effect of five dental luting cements which were based on glass ionomer cement technology. METHODS Five diff...

GHB and its related compounds have been known for years in forensic toxicology because of their illicit use in drug-facilitated sexual assault, and to a lesser extent, as party drugs. A sensitive and specific method for the identification and quantification of gamma-hydroxybutyric acid (GHB) in saliva has been developed using gas chromatography-mass spectrometry with selective ion monitoring mo...
