ANT334H5 Lecture Notes - Lecture 4: Periodontal Fiber, Diphyodont, Periodontitis
Document Summary
Evaluate health and well-being: dental disease + overall health has many links. Estimate age-at-death for archaeological purposes hard to do in modern day. Record/identify cultural practices bioarchaeological + modern cultures. Heterodont: different types of teeth for different functions. Incisors: scraping, gripping, as a tool and for eating, thin from front to back to use as scrape. Canines: tearing, puncturing, robust at crown. Premolars & molars: crushing, grinding, multiple cusps and flattened on ocusal (chewing surface) Deciduous: formed in utero, erupt during infancy (ca 6-9 months, evulsed (lost) during childhood (beginning age 6, more variable than teeth development, 20 deciduous teeth, no premolar, no 3rd molar. Teeth are better at age estimation than bones for children. 32 adult teeth 8 for each quadrant. Number of different types of teeth the species has in 1 quadrant of dentition. Adult human 2123: 2 incisors, 1 canine, 2 premolars, 3 molars. Subadult human 2102: 2 incisors, 1 canine, 2 molars.
