Dental Cavities May Lower Cancer Risk


Dental cavities may have an unexpected twist for good. A study by the University of Buffalo researchers have discovered a link between dental cavities that reduce the risk of head and neck cancer. The results are surprising and the researchers are trying to connect the links while addressing the consequences of both the dental cavities and cancer.
Dental cavities (or caries) are caused by tooth decay. This is when the bacteria present in the mouth make lactic acids that strip away minerals in the tooth by fermenting carbohydrates. According to the researchers from the University at Buffalo, NY, previous studies have shown the bacteria that causes tooth decay is linked to an immune response, which may be protective against cancer.

New Device Saves Jaws Damaged by Cancer


A new artificial device may win the fight against the results of periodontitis and mandibular cancer. Mandibular cancer potentially disfigures the face and periodontitis causes teeth to loosen over time. Dentists are able to insert artificial scaffolding to determine the new bone tissues growth. The foam and rubber helps the body repair itself. Learn more about the scaffolding device and the benefits it could offer.
To begin with, the invention can save those who suffer from loose teeth and damaged mandibles. Periodontitis is a troublesome infection of the gums. When the infection causes the bone adjacent to teeth to break down, the teeth come loose. Mandibular bone can also be damaged by cancer, infections and accidents. Using this new method, dentists can insert artificial scaffolding that will determine where the new bone tissue will grow. To understand this method, we need to understand how bone can repair itself. After a fracture, the bone fragments can knit together only if they are in very close contact. Even if they have the ability to do this, there are major limitations. When a bone fractures, a lot of blood collects at the site of fracture. Blood contains organic molecules that coalesce into long strands. This coagulum is then populated with cells and turn into connective tissue that later calcify. The connective tissue functions as a porous growth platform for bone cells and blood vessels. The bone cells remodel the calcified structure and forms functional bone. New blood vessels help bring nutrients and oxygen.
