dc:description "Merged the 2017-2018 dentition and demographics files on SEQN, kept complete dentition exams, and computed the examination-weighted proportion with at least one third molar coded as a permanent tooth present. a-star is the youngest age from 12 to 30 at which that proportion reaches half the maximum at ages 25-28.";
<http://www.w3.org/2000/01/rdf-schema#comment> "Measured: 18 years (age at half the late-twenties third-molar presence) (n = 1341). Interpretation: The last grinding teeth are the third molars, tooth-count positions 1, 16, 17 and 32 in the NHANES dentition exam. Code 2 is a permanent tooth present. Code 4 (not present) mixes not-yet-erupted, extracted and congenitally absent teeth, so the curve is a presence curve, not a direct eruption-date curve. 'About twenty' is the ages 18 through 22. 'Sometimes in old age' cannot be read from a later presence and is left untested.";
