Metal deposits in children's teeth may portend future GI problems
Early childhood exposure to copper, zinc, chromium and lead is a potential risk factor for inflammatory bowel disease. Scientists made such an assumption by examining the milk teeth of patients with gastrointestinal problems preserved from childhood.

Inflammatory bowel disease (IBD) is a chronic condition that primarily includes ulcerative colitis and Crohn's disease. Very little is known about the causes of their occurrence. Even such studied risk factors as smoking are very weakly associated with the mechanisms of the disease itself.
A new study published in Gastroenterology has shown that environmental pollution with toxic metals can be an important risk factor for IBD. If the new theory is vein, their impact on pregnant women and young children is especially dangerous.
In the study, researchers examined the chemistry of 28 deciduous teeth in 12 adult IBD patients (seven with Crohn's disease and five with ulcerative colitis). They compared these data with those of 16 healthy people from the control group. The study participants lost milk teeth on time, they were saved by their parents and provided to the scientists.
Scientists have resorted to dental analysis because only he could provide information about the effects of metals in the past, including early childhood and intrauterine development. Data on what metals entered the body of children can be obtained from the layer-by-layer study of the teeth - each layer corresponds to a certain age.
The findings suggest that intrauterine and early childhood IBD patients were significantly more exposed to zinc, lead, copper and chromium than controls.
Deposits of metals in teeth are resistant, they easily persist for years, so it was not difficult for scientists to detect them. "Findings" of scientists belonged to the period from the 25th week of intrauterine development to the sixth month of life. In patients with IBD, the level of all studied metals was higher.
Scientists write that lead is known as a toxin that causes inflammation, in experiments on mice, it caused colitis, disrupted the gut microbiome and metabolism. The development of IBD was associated with the effect of zinc and copper on the child's body in utero and at 18 weeks of life, chromium - from 9 to 15 weeks.
Scientists note that this scientific work cannot conclusively prove that heavy metals are the cause of IBD, this issue needs to be studied in larger studies.
