Do you suffer from tooth sensitivity or have heavy hand on brushing abrading your teeth, then your worries are nearing to the end. Russian Scientists have developed the Metal Nano-particles to kill oral bacteria.
An innovative mouth wash developed at the National University of Science and Technology MISIS (NUST MISIS) in cooperation with researchers from Vyatka State University was shown to have a substantial impact on oral cavity micro-flora, removing about 83% of dental plaque.
It's effectiveness was proven during clinical trials at the Dentistry Department of Kirov State Medical University.
Dentists currently recommend mouthwash and oral irrigation devices that use a stream of pulsating water to remove dental plaque; as supplement in oral hygiene which helps to kill bacteria that can cause plaque formation, and remove food debris between teeth that cannot be removed easily with a toothbrush or floss. In coordination with medical experts, NUST MISIS researchers developed an oral rinse that, if used regularly, suppresses pathogenic oral bacteria, reducing the risk of dental carries and gum diseases. The product’s effectiveness is based on the use of metal nano-particles. Experiments showed that these particles stop bacteria that cause plaque from growing.
Svetlana Gromova, Dean of the Dentistry Department at Kirov State Medical University and the project's Co-author says,
“Pathogenic bacteria can be killed through chemical destruction of cell walls and various membranes, including cell organelle membranes, specifically when metal nano-particles enter into contact with bio-polymers of microbial cells. The cell membrane breaks down, releasing its content into the environment. With its bactericidal and bacteriostatic properties, the solution exceeds antibiotics by far when it comes to dealing with staphylococcus aureus and most coccus varieties.”
During clinical trials at Kirov’s Dentistry Department, volunteers were asked to use the new mouthwash for one month, and measurements were taken after 14 and 30 days of using the product. Observations shown that bacteria that cause plaque are sensitive to various solutions that contain metal oxide nano-particles. Microorganisms were also less prone to adhering to teeth and causing inflammation. If used regularly, the rinse helped to reduce the oral fungal microbes,too; normalizing salivary pH.
Head of the research team, Associate Professor at NUST MISIS Department of Physical Chemistry, Georgy Frolov said on the scientific outcome of the experiments:
“Colloidal solutions of metal oxides are not toxic to humans. They have a lasting anti-bacterial effect against dental plaque microorganisms, while also serving as a source of microelements. As we saw during research, using a metal oxide mouthwash substantially reduces soft dental deposits, reducing pathogenic microflora, all but eliminating it.”
NUST MISIS laboratories are currently making the first test batches of the product, patents and registration documents for medical use have been filled.
So, this is a big leap towards effective plaque control because the contemporary methods of plaque control fall short on one or more aspect. Even though it can't be expected from it to completely replace the tooth brushing but can be a great adjuvant to the regular mechanical method like Tooth brush and flossing.
Although, the mouthwash may not have the universal appeal and experts may have difference of opinion on use of mouthwash as exclusive measure of plaque control but it can be a great alternative to the people with abraded teeth and for disabled.
