Gustafson's Method in Dental Age Estimation

The video tutorial explains Gustavson's method for estimating dental age using six criteria: attrition, secondary dentine, periodontosis, cementum opposition, root resorption, and transparency of the root. Each criterion is ranked on a scale from 0 to 3, and the total score is used in a formula to estimate age. The video provides detailed explanations of each criterion and demonstrates the calculation process with an example.

What is the primary purpose of Gustafson's method?

• To design dental prosthetics

• To improve dental hygiene

• To diagnose dental diseases

• To estimate the age of a person using dental criteria

Which of the following best describes attrition in the context of Gustafson's method?

• Loss of tooth color

• Deposition of minerals

• Wear and tear of tooth surfaces

• Inflammation of gums

What does a score of A3 indicate in the attrition criteria?

• Attrition has reached the dentine

• Attrition has reached the pulp

• Attrition in the enamel area

• No attrition

What is secondary dentine?

• A layer of dentine formed after the tooth root is fully developed

• A mineral deposit on teeth

• The initial layer of dentine

• A type of dental disease

What does periodontosis lead to?

• Growth of new teeth

• Whitening of teeth

• Loosening of teeth in the socket

• Strengthening of teeth

What does a C3 score indicate in cementum opposition?

• No cementum deposition

• Greater layer of cementum

• Slightly greater than normal cementum

• Very heavy layer of cementum

What is the role of odonto class cells?

• Formation of tooth cells

• Degradation of dental cells

• Production of saliva

• Strengthening of enamel

Which criterion is considered the most reliable in Gustafson's method?

• Attrition

• Periodontosis

• Cementum opposition

• Transparency of root

What is the formula used in Gustafson's method to estimate age?

• 15.00 + 2.00 * total score ± 5.00 years

• 12.00 + 3.00 * total score ± 4.00 years

• 10.00 + 5.00 * total score ± 2.00 years

• 11.43 + 4.56 * total score ± 3.63 years

In the example calculation, what is the estimated age range of the person?

• 40-45 years

• 30-35 years

• 26.04-33.3 years

• 20-25 years
