b) Used to estimate age only in living

c) Secondary dentin formation

d) Root transparency

1. A, b & c  
2. A & c  
3. C & d 
4. A & b

Answer:-3

Gustafson's method

• It is a method wherein various criteria of normal physiological changes in a tooth other than dental eruption order are considered in determining the age of a person.
• It is useful in determining the age of the victim when teeth are the only trace evidence collected as in cases of victims of a bomb blast or air crash disasters.
• Parameters which are evaluated in this method:- 

1. Amount of occlusal attrition (a)
2. Degree of secondary dentin deposition (s)
3. Loss of periodontal attachment (p)
4. Cementum apposition at the root apex (c)
5. Root resorption at the apex (r)
6. Degree of root transparency (t)

• Age can be estimated by using the formula given below
