Harvard University research revives use of decades-old famous St. Louis Baby Tooth Survey | Health
Part of the research will be to find 1,000 adults in their 60s and 70s who took the baby teeth survey and look for links between metal levels in their milk teeth and current cognitive health.
Most of the dental survey respondents are from the St. Louis area, and Missouri has about 33 Superfund locations – toxic waste landfills that require long-term federal cleaning. New toenail and blood samples must be sent for Harvard’s study.
Before tracking down the study participants, the grant covered the cost of a careful but important process: all of the information from the note cards had to be entered into a digital spreadsheet.
The information included the child’s name, the age the child’s mother lived in the last six months of pregnancy, the city the child lived in during the first year of life, how long the child was breastfed, and whether there was any other milk drank in the first year of life.
A friend of Mangano’s, Steven Olenik, 31, spent basically the entire COVID-19 pandemic entering the dates while repeating Pearl Jam and Phish concerts in a small rented office space. Olenik started in February 2020 and is almost done.
Previous estimates put the number of teeth at 85,000. It turns out there are more than 100,000.
While the Superfund study involves testing the milk teeth of just 1,000 people, the researchers will try to contact all donors of the remaining teeth, according to Weisskopf. Weisskopf estimates that some incisors, canines, and molars come from the same child and that these are around 60,000 people.
