Study indicates that aspirin can reverse caries damages
According to a study conducted by researchers at Queen's University in Belfast, Northern Ireland, acetylsalicylic acid (active ingredient aspirin, analgesic with anti-inflammatory action) can stimulate the regeneration of teeth, filling the cavities damaged by caries.
To reach this finding, the scientists analyzed data from previous research. They then tested how the liquid form of aspirin reacted to the stem cells of the teeth and found that this combination produced the dentin, the inner layer that surrounds the nerve, located just below the enamel, which is deteriorated by a substance produced by the excess of bacterial plaque (causing cavities).
The teeth have limited regeneration capacity, so they can repair a thin layer of damaged dentin, but not a large cavity. The treatment most used by dentists is the application of sealants and resins, so an individual may need replacement several times during the life of the tooth.
According to the author of the study Ikhlas El Karim, treatment with aspirin could result in a reduction of cavities and fillings in the future. "We hope to develop a treatment that gives the teeth the ability to make these repairs, but that will be gradual, it is not immediately that we will no longer need fillings," the scientist explains. to understand the benefit of the drug and find a way to properly apply aspirin to the tooth.
"We need to put the product (on the decayed tooth) so that it can be released over a long period of time. in a caries today, it will be easily washed.We are not encouraging this simple use, but rather the end product to be used by a dentist, not a patient, "the scientist commented. that the fact that aspirin is already a drug available on the market will help the development of a treatment. "We will not need 10 or 20 years to do clinical trials, and there is tremendous potential to change the way we approach one of the greatest dental challenges we have, and this method not only increases tooth survival but can result in immense system economics of public health around the world.

Ministry of Health intends to include the Zika virus in the NAT test, DNA test currently used to detect HIV and hepatitis B virus and hepatitis C in blood bags donated in national blood centers. The development of the new NAT test will be done by the Biomanguinhos Laboratory of the Oswaldo Cruz Foundation (Fiocruz), in Rio de Janeiro, already the creators of the previous test.
Who has never been hoarse from cheering for your team or screaming at a show your favorite band Hoarseness is common after excessive vocal exertion. It is a result of edema or redness in the vocal cords and usually improves in a few days. The problem is when that hoarseness persists for months. The voice and therefore human speech is the result of an ingenious process of modulation of the air that comes from the lungs in order to produce complex sound effects.
