Cross-sectional study of the association between serum perfluorinated alkyl acid concentrations and dental caries among US adolescents (NHANES 1999-2012).

ABSTRACT:

Study objectives

Perfluoroalkyl acids (PFAAs) are a class of anthropogenic and persistent compounds that may impact some biological pathways related to oral health. The objective of our study was to estimate the relationship between dental caries prevalence and exposure to four PFAA: perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA), perfluorohexane sulfonic acid (PFHxS) and perfluorooctane sulfonic acid (PFOS) in a nationally representative sample of US adolescents.

Setting/design

We analysed cross-sectional data from the National Health and Nutrition Examination Survey from 1999 to 2012 for 12-19-year-old US adolescents.

Participants

Of 10 856 adolescents aged 12 to 19 years who had a dental examination, we included 2869 with laboratory measurements for s
