Role of Antioxidants in Dentistry. An antioxidant is a molecule which inhibits oxidation reaction. Antioxidants terminate the chain reaction caused by free radicals of oxidation reaction thereby preventing cell damage or death of the cells. Antioxidants are compounds that inhibit oxidation. Oxidation is a chemical reaction that can produce free radicals, thereby leading to chain reactions that may damage the cells of organisms. Antioxidants such as thiols or ascorbic acid (vitamin C) terminate these chain reactions. To balance the oxidative stress, plants and animals maintain complex systems of overlapping antioxidants, such as glutathione and enzymes (e.g., catalase and superoxide dismutase), produced internally, or the dietary antioxidants vitamin C and vitamin E.The term "antioxidant" is mostly used for two entirely different groups of substances: industrial chemicals that are added to products to prevent oxidation, and naturally occurring compounds that are present in foods and tissue. The former, industrial antioxidants, have diverse uses: acting as preservatives in food and cosmetics, and being oxidation-inhibitors in fuels.Antioxidant dietary supplements have not been shown to improve health in humans, or to be effective at preventing disease.Supplements of beta-carotene, vitamin A, and vitamin E have no positive effect on mortality rateor cancer risk.needs update Additionally, supplementation with selenium or vitamin E does not reduce the risk of cardiovascular disease.Antioxidants are substances that may protect your cells against free radicals, which may play a role in heart disease, cancer and other diseases. Free radicals are molecules produced when your body breaks down food or when you're exposed to tobacco smoke or radiation Antioxidants In Dentistry Scientific Journals. Antioxidants are molecules that act against the process of oxidation. The large, complex antioxidant molecules can bond with the unpaired electrons of free radicals, effectively neutralizing the oxidation process. Antioxidants are molecules that act against the process of oxidation. The large, complex antioxidant molecules can bond with the unpaired electrons of free radicals, effectively neutralizing the oxidation process. They act by inhibiting reactions caused by the oxidation process. They neutralize ROS by donating one of their own electrons. They are stable and help to prevent further cell damage. Scientific journal is a periodical publication intended to further progress of science, usually by reporting novel research. There are thousands of scientific journals in publication, and many more have been published at various points in the past. Most journals are highly specialized, although some of the oldest journals publish articles and scientific papers across a wide range of scientific fields. Scientific journals contain articles that are peer reviewed, to ensure that articles meet the journal's standards of quality, and scientific validity. The publication of the results of research is an essential part of the scientific method. If they are describing experiments or calculations, they must supply enough details that an independent researcher could repeat the experiment or calculation to verify the results. Each such journal article becomes part of the permanent scientific record.
