Analyze chemical substances contained in 'teeth' to measure the risk of disease

Human teeth begin to develop teeth from about 6 to 8 months after birth, and eventually become permanent teeth . It is reported that by analyzing chemical substances contained in such human teeth, it is possible to measure what type of disease risk the person has.

Usually, when the child's teeth fall out, it is mostly thrown away as it is. However, Mr. Mannish Arora , a researcher at Mount Sinai Medical University in New York, developed a way to exploit missing teeth as a type of human sample to find early signs of illness.

Mr. Arora said, "Human teeth are biological recording media, and by analyzing teeth you can see what kind of chemicals the person has been exposed to." By analyzing chemical substances contained in human teeth, we can find signs of diseases such as autism , ADHD , cancer and amyotrophic lateral sclerosis, and if we can do early treatment, Arora He thinks.

Especially Mr. Arora is paying attention to the tooth which automatically falls out when it reaches a certain age. Mr. Arora uses a laser light that is as thin as about a tenth of the hair, and Mr. Arora is doing research to map the sign of the disease accumulated inside the teeth. By clarifying to what extent chemicals are accumulated in the place of the deciduous teeth, to what extent the risk of the disease is found, it can be used for early detection and treatment of the disease.

When Mr. Arora was enrolled in the doctoral course at Sydney University , his colleague informed me that he was interested in the research that "the amount of lead contained in the child's teeth tooth increases, the child's IQ goes down" about. After that, Mr. Arora cooperated with the Department of Physics to develop an analytical method using laser light and so on and devised a method to detect chemical substances from comparatively easy-toy teeth.

At Mount Sinai Medical College Mr. Arora was studying the impact of humans being exposed to chemicals. During that time, Mr. Arora discovered that autistic children can not handle certain chemical substances in the body and accumulate them. Dysfunction related to chemical substance treatment seems to occur from the third week of pregnancy, and although the cause of malfunction is unknown, accumulation of chemical substances in the body leads to the early detection of autism, Mr. Arora said about.

If we find out that children are autistic at an early stage, it will be possible to treat as soon as possible and also to practice quick care for children with autism. Of course, it can not be analyzed until the teeth fall out without permission, but it may be a clue to find early signs of disease from other samples, such as blood and urine, based on the data obtained from the study. "I can not change genes I was born, but later environments can be changed by discovering diseases," Arora said.
