Skeletal Age Estimation Techniques

This video tutorial covers age estimation through skeletal analysis, focusing on skull sutures. It explains the fusion process of various sutures, including sagittal, lambdoid, and coronal, and their timelines. The video also discusses metopic sutures and the condition known as metapism, where these sutures do not fuse. The tutorial provides detailed timelines for the fusion of different parts of the skull, aiding in accurate age estimation.

Which bones are primarily used for age estimation in skeletal analysis?

• Femur, tibia, and fibula

• Skull, pelvis, and long bones

• Ribs, spine, and pelvis

• Humerus, radius, and ulna

What is the most reliable type of skull suture fusion for age estimation?

• Ectocranial fusion

• Endocranial fusion

• Lambdoid fusion

• Coronal fusion

Which skull suture provides the best estimate for age determination?

• Sagittal suture

• Metopic suture

• Coronal suture

• Lambdoid suture

At what age does the anterior part of the sagittal suture typically fuse?

• 18 to 21 years

• 50 to 60 years

• 40 to 50 years

• 30 to 40 years

Which part of the sagittal suture fuses first?

• Middle part

• Anterior part

• None of the above

• Posterior part

By what age is the lambdoid suture expected to complete its fusion?

• 45 years

• 30 years

• 60 years

• 50 years

How is the coronal suture divided for age estimation purposes?

• Into three equal parts

• Into left and right halves

• Into anterior and posterior halves

• Into upper and lower halves

What is the term used when metopic sutures do not fuse?

• Non-fusion

• Suture delay

• Metapism

• Lapsed union

What percentage of people exhibit metapism?

• 3 to 4 percent

• 1 to 2 percent

• 5 to 10 percent

• 10 to 15 percent

What is the significance of the metopic suture in age estimation?

• It is the most reliable suture for age estimation

• It is the last suture to fuse

• It is not used in age estimation

• It divides the frontal bone into two parts
