A)Both statements are true.
B)Both statements are false.
C)First statement is true,second statement is false.
D)First statement is false,second statement is true.

Answer 1

A
Explanation: A)Dental caries has both environmental and genetic components;because of this,it is important that detailed dental histories be gathered.This does include dental history of parents and siblings and nutritional and oral habits.
