Week 7 & 8 - Age Estimation

Question 1

chronological vs biological age

Answer 1

CA
- > measured by time (days, months, ect.)
BA
- > a function of genetics, nutrition, environmental factors, and activity
- > not perfectly correlated because skeletal aging is different between individuals

Question 2

trajectory affect

Answer 2

the gap between the chronological and biological ages widens with age (due to variable wear and tear)

Question 3

what age estimation methods do we use in non adults

Answer 3

teeth
- > their formation, mineralization, and eruption of permanent dentition
bones
- > ossification, long bone growth, and epiphyseal union

Question 4

relate diaphyseal growth to AE

Answer 4

• > strong linear relation of diaphysial growth (middle length) to age
• > little variation between sex and population

Question 5

ages estimation techniques in adults

Answer 5

- > Pubic symphysis best documented area for
skeletal aging
- > Suchey-Brooks method
- > auricular surface
- > we look at degenerative changes

Question 6

Suchey-Brooks method

Answer 6

• Changing features found
on and surrounding the
pubic symphyseal face
• 6 phases

Question 7

pros and cons to Suchey brooks method

Answer 7

Pros
• Female and male
standards
• Upper and lower limits of
each phase
Cons
• Large age ranges

Question 8

auricular surface

Answer 8

• Age-related changes from
remodelling of the joint
surface
• 8 phases
• Better preserved
(location/bone density)
• Traits are more subtle
