Association between hair disorders and dental problems determined in study

You might not be losing your hair over dental problems, but could it be that you're losing your teeth over hair problems?

According to a study released this spring, certain hair disorders may put people closer to risk for dental health challenges.

Researcher Olivier Duverger, Ph.D., and co-authors of the study found that epithelial hair keratins are also crucial components of tooth enamel and that mutations in these keratins increase the risk for dental defects and caries. Dr. Duverger is a researcher at the National Institutes of Health-National Institute of Arthritis and Musculoskeletal and Skin Diseases in Bethesda, Maryland. He presented these findings in March at the 93rd General Session and Exhibition of the International Association for Dental Research in Boston.

In the study, the researchers assessed the presence and function of specific hair keratins that are also part of fully mineralized enamel in teeth. They used genetic and intraoral examination data from 386 children and 706 adults, testing the association between polymorphism in hair keratin – associated with hair disorders – with susceptibility to dental caries – or cavities. They found that hair keratin mutations led to altered enamel structure and reduced enamel hardness.

How Is Tobacco a THREAT TO ORAL HEALTH?

Tobacco's greatest threat to your health may be its association with oral cancer. The American Cancer Society reports that:

  • About 90 percent of people with mouth cancer and some types of throat cancer have used tobacco. The risk of developing these cancers increases as people smoke or chew more often or for a longer time.

  • Smokers are six times more likely than nonsmokers to develop these cancers.

  • About 37 percent of patients who continue to smoke after cancer treatment will develop second cancers of the mouth, throat or larynx. While only 6 percent of people who quit smoking will develop these secondary cancers.

  • Smokeless tobacco has been linked to cancers of the cheek, gums and inner surface of the lips. Smokeless tobacco increases the risk of these cancers by nearly 50 times.7
