4 News 5/19 Teeth can reveal the stress levels of patients Source: pxhere by Dental Tribune International WASHINGTON, U.S.: Exfoliated teeth, one of the few tissues in our body that record the history of environmental insults, are turning out to be a promising biomarker for modern medicine. The researchers at the American Association for the Advancement of Science (AAAS) in Washington showed the emerging evidence that teeth can reveal stress levels of patients. The most critical finding is that children’s teeth can reveal whether they were exposed to high stress in their early years. At the AAAS meeting, Dr. W. Thomas Boyce, Professor of Pediatrics and Pediatric Psychiatry at the University of California, San Francisco, showed that the individual layers of tooth enamel would be thinner and less dense if exposed to stress, which would make the teeth prone to develop cavities. These structural changes in the enamel layers can be measured by studying a primary tooth in a 3-D model based on a radiograph. The childhood stress might come from excessive demands at school as well as from stressful parental relationships. Even other factors like constant noise, physical and/or mental abuse etc. can play a role and cause stress. Individuals who experience levels of stress produce greater amounts of cortisol, the stress hormone, the concentration of which can be measured in the blood and saliva. increased “But, of course, what we really want and what we are really after and what these snapshots fail to show is total cortisol exposure,” said Dr. Boyce about its limitation. Hence, examining the actual teeth can reveal exactly this, as cortisol influences the development of teeth. The presentation, titled “Social disparities in child oral health: Interactions between stress and pathogens,” was presented on Feb. 15, 2019, in a scientific session at the Annual Meeting of the AAAS.
