Cu-Al-Nishape memory alloys (SMAs) are widely known for their better properties in comparison to other SMAs (lower production costs, increased ductility, enhanced machinability, reduced liquidus temperature, and decreased hysteresis), but there is still controversy terms of the biological these materials. The aim this study was evaluate biofunctional performances Cu-Al-Ni alloy produced by cont...

Background and Aim: Controversy exists regarding the correlation of saliva secretion with obesity. Considering the significant role of saliva in oral and dental health and the increasing prevalence of obesity in Iran in the past three decades, this study aimed to assess the independent association of anthropometric indices including body mass index (BMI), weight gain after the age of 20 years a...

It is well known that the addition of saliva to blood will accelerate its coagulation (1, 2, 7). This property of saliva is not species specific. It has been shown that dog, cat and human saliva will indiscriminately accelerate the clotting of blood obtained from the dog, cat, cow or man (1, 7). Bellis, Birnbaum and Scott (1) noted that while the clotting factor of saliva was stable at 60 " , i...

Background: Dental caries occur due to a dynamic demineralization process that happens when calcium and phosphate ions are dissolved carbohydrates fermented by microorganisms in the mouth, leading decrease saliva pH. Saliva production occurs as response stimuli such tasting chewing food. contains oral cavity bacteria, cervical gingival fluid, leftover food, known whole saliva. Normally, pH rang...

The aim of this study was to investigate the rheological behavior and mucoadhesive nature of saliva substitutes, by incorporating various mucoadhesive polymers into an artificial saliva pump spray formulation. For this purpose various mucoadhesive polymers including cellulosic polymers in the range of 0.1-1.0% and Carbomers such as C974p, C971, C934p and C971 in the range of 0.01-0.1% were adde...

A surface-enhanced Raman scattering (SERS) biosensor has been developed by incorporating a gold nanohole array with a SERS probe (a gold nanostar@Raman-reporter@silica sandwich structure) into a single detection platform via DNA hybridization, which circumvents the nanoparticle aggregation and the inefficient Raman scattering issues. Strong plasmonic coupling between the Au nanostar and the Au ...

introduction: the aim of this study was to assess the galvanic behavior of different bracket and archwire combinations that are commonly used in orthodontic treatments. methods: three types of orthodontic archwires with a diameter of 0.016×0.022 inch and 80 standard edgewise maxillary central incisor brackets were selected. three groups consisted of different wire-bracket couples and one group ...
