El grosor de las marcas de crecimiento en los dientes de leche, al igual que los anillos de un árbol, pueden ayudar a identificar a los niños con riesgo de sufrir depresión y otros trastornos mentales más adelante, según investigadores del Hospital General de Massachusetts, afiliado a Harvard. Los resultados de este estudio se publicaron en JAMA Network Open.

Exposure to sources of physical stress, such as poor nutrition or disease, can affect the formation of dental enamel and result in pronounced growth lines within teeth, called stress lines, which are similar to the rings in a tree that mark its age. Just as the thickness of tree growth rings can vary based on the climate surrounding the tree as it forms, tooth growth lines can also vary based on the environment and experiences a child has in utero and shortly thereafter, the time when teeth are forming. Thicker stress lines are thought to indicate more stressful life conditions.
No one is certain what causes the NNL to form, says Dunn, but it’s possible that a mother experiencing anxiety or depression may produce more cortisol, the “stress hormone,” which interferes with the cells that create enamel. Systemic inflammation is another candidate, says Dunn, who hopes to study how the NNL forms. And if the findings of this research can be replicated in a larger study, she believes that the NNL and other tooth growth marks could be used in the future to identify children who have been exposed to early life adversity.

Lo que muestra los trastornos mentales es si estás registrado en Menéame o no.
Pero como los van a analizar si se los lleva el Ratoncito Perez?
