Researchers create thin film polymer membranes capable of separating fluoride from chloride and other ions. Targeted ion selectivity by the filtering membranes could have important implications for water purification, environmental remediation and industrial production.
Chula Faculty members joined forces in dental materials science to develop easy-to-use “light-activated dental materials” that meet international standards and help shorten tooth filling time. The secret of these innovative dental materials, made by Thai people, is Acemannan polymer from Aloe Vera that can stimulate the formation of dentin and reduce tooth sensitivity in many dental health products.
Research investigates how fluorine levels affect beneficial soil microbes
Exposing teeth to excessive fluoride alters calcium signaling, mitochondrial function, and gene expression in the cells forming tooth enamel—a novel explanation for how dental fluorosis, a condition caused by overexposure to fluoride during childhood, arises. The study, led by researchers at NYU College of Dentistry, is published in Science Signaling.
A new study by two University of Washington researchers and their colleagues questions the cost-effectiveness of fluoride varnish for preschoolers and calls its anti-cavity effects “modest and uncertain” in this age group.
