DHEP, a chemical compound of the phthalate family, is still present in small quantities in many medical devices despite regulations limiting its use. Work carried out under the direction of Sylvie Babajko (1, 2) at the Centre de Recherche des Cordeliers indicates that even at very low doses, DHEP impacts the development of teeth. This observation is all the more worrying as DHEP is found in medical devices used in neonatology.
These results, published in the journal “Environmental Health” Perspectives in June 2022, were the subject of a press release.
