4) The face forms only 1/8th of the bulk of head whereas in the adult it forms 1/3rd to of the bulk.
Pedodontics Answer: 4
Due to the advanced state of the growth of brain this size at birth of the head of the infant is relatively large . only 1/8th of the bulk of the head forms the face at this age, whereas in the adult it forms 1/3rd to of the bulk. The face appears to be under the bulge of the forehead because the vault of the cranium is so large

3. Nature of bone loss
4. Type of instrument
