ANT334H5 Lecture Notes - Lecture 4: Cervix, Osteology, Pus
Document Summary
Lecture 4 - dentition, anatomy, development and pathology. Why study human teeth: to assess population affinities, to learn about adaptations. Direct contact with environment: we can tell a lot about their diet, or even if their teeth were used as tools. Under strong genetical control: to evaluate health and well-being. Ex: pathology, trauma: to estimate age at death. Least affected by stress: to record/identify cultural practices. Ex: filing, inlaying: to apply to forensic situations. Ex: bite mark analysis, individualization via dental records. Heterodont = there are different forms of teeth for different functions. Diphyodont develop 2 sets of teeth (most mammals are, including. Deciduous teeth (baby/milk) teeth n =20: are formed in utero, erupt in infancy beginning at around 9 months, avulse during childhood (approx. Adult teeth n =32: develop during infancy (approx. 6 months: they begin erupting during childhood (6 years) into late teens. Number of different types of teeth that the species has per quadrant.
