Case Study #30

Yes, this person is approximately 7 - 8 years of age because:

first molar roots are fully formed from 9 - 10 years of age; notice that these apices of the first molar are not fully closed yet
first premolar is not yet erupted - it erupts at age 10 - 12
second premolar is not yet erupted - it erupts at age 13 - 14

first molar is fully erupted - this indicates the child is at least 6 - 7 years of age
