Researchers at Oregon State University have discovered the gene responsible for growing enamel, a hard outer layer of the tooth that cannot be grown back once it begins to decay. In the most recent research, mice were bred without the gene known as Ctip2. Researchers noticed that mice born without this gene were missing the enamel layer of their teeth, and determined the gene was crucial for the formation and function of enamel producing cells. This discovery could impact greatly on the field of dentistry, making techniques such as drilling and filling to treat tooth decay obsolete. Research leader Chrissa Kioussi states that by understanding the role of genetics in tooth development, we may be able to develop means of tooth repair and even the production of new teeth altogether.
