Most of the population of our planet have some or other problems with the teeth. And almost all of us have seals. But the fillings are short-lived. They are destroyed and require replacement. However, recently, scientists have created a filling material that does not require replacement throughout life.
The main cause of destruction and loss of seals are pathogenic bacteria that eventually multiply in the micro-gap between the filling and the tooth. It appears almost always and does not depend on the quality of the dentist's work. The new type of fillings differs from the long-used antiseptic effect, and their longevity exceeds the service life of classical fillings by several dozen times.
Antibiotics are used even now when installing seals, but these antibiotics are used topically, and they last no longer than a few weeks. The advantage of new seals is their composition. The filling material is mixed with special antibiotic nanoparticles that make the seal super-resistant to microbes on the entire surface, and these properties do not disappear with time. Thus, the antibiotic is not only in the gap between the filling and the tooth. This gives local immunity to lesions in the area of filling the seal. The first experiments have already shown the effectiveness of the new material. According to one of the authors of the work,
"To date, antibiotics are used to install seals, but the duration of such formulations does not exceed several weeks. We managed to find such a combination of drugs and microscopic nanoparticles that would contain enough substances that would be enough to protect the teeth for many years. "
