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. https://w3id.org/delphi/resource/assessment/aristotle-ga05-25--claim-test--pr-169 http://www.w3.org/2000/01/rdf-schema#label Claim test of aristotle-ga05-25 (pr-169): supports, confidence 0.7 https://w3id.org/delphi/resource/assessment/aristotle-ga05-25--claim-test--pr-169 http://www.w3.org/2000/01/rdf-schema#seeAlso https://github.com/fractastical/delphisci/blob/bf2af6ee0a84e23ffa6414ad7a0a50a8c276506e/test-data/claim-tests/aristotle-biology/aristotle-ga05-25/pr-169/result.json https://w3id.org/delphi/resource/assessment/aristotle-ga05-25--claim-test--pr-169 http://www.w3.org/ns/prov#wasAttributedTo https://w3id.org/delphi/resource/agent/delphisci-claim-tester-grok-4-7 https://w3id.org/delphi/resource/assessment/aristotle-ga05-25--claim-test--pr-169 https://w3id.org/delphi/ontology/admissibleDatasets A public dental examination of a human population that records third-molar presence by single year of age across the teens and the twenties, with an examination weight.
