Genetic causes of tooth decay were clear anthropologists long time because of the varying susceptibility of the disease of people of different races. Scientists from the University of Zurich (Switzerland) were able to identify a genetic complex responsible for the formation of tooth enamel. Mutation of the gene in this area increases the risk of disease.
Scientists from the Center of dental medicine at the Institute of Molecular Biology have investigated in the laboratory mice with different mutations in proteins of tooth enamel. All these mice were apparent tooth enamel defects. And the scientists were able to detect a direct link between genetic mutations and defects in tooth enamel.
Opening of Swiss scientists to better understand the processes of formation of tooth enamel and tooth decay. It has appeared that the risk is based not only on bacteria of the oral cavity, but also the reliability of the teeth themselves and their endurance.
