You visit your uncle, a dentist, over winter break. he hands you this x-ray and instructs you to estimate the age of this child, given the eruption time of the permanent molars (6 years old for the first molar, 12 years old for the second, and 18 years old for the third). you reply that the child is in which age range?

The age range of the child is "6 to 12 years".

The first molar has ejected through the jaw bone, yet the second molar is still inside the jaw and its enhancement isn't finished, because it doesn't have roots. That implies the child from which this x-ray came is in the age between 6 and 12 years.
