Jeffrey Ebersole (Dental) co-authored “Epidemiologic Evaluation of Nhanes for Environmental Factors and Periodontal Disease,” which appeared in the June issue of Nature Scientific Reports. The study’s findings indicated an array of environmental variables were different in periodontitis among smokers, former smokers, and non-smokers, with a subset of specific environmental variables identified in each population subset. Discriminating environmental factors included blood levels of lead, phthalates, selected nutrients, and polychlorinated biphenyls (PCBs).
