Since last April he has grown 5 inches and is now 62 and. He soon turned 14 in June 2010 and we were reassured he wouldnt grow much more as he had alot of hair growth on his legs and he felt he was reaching puberty quickly.
The correlation between the age assessed from dental development and that assessed from the hand and wrist bones is not very strong, suggesting that the growth of these tissues is separately programmed and that there is not a close relationship between the development even of similar tissues. He had x-rays done on his hand which showed his bone age to be 15yrs, a good two years older than his chronological age. The calcification and eruption of the deciduous teeth occur at similar rates in males and females, but calcification and eruption of the permanent teeth are earlier in females. X-ray pictures of the bones of the hands and feet are used to assess a bone age in the same way as X-ray pictures of the jaws may be used to assess dental age.ĭevelopmental age may also be assessed by the appearance of the teeth or, preferably, by X-rays of the teeth and jaws. Only black hair is found on the genitalia. No breast tissue and axillar hair isfond on the examination. 4 year of advancement of bone maturation is seen. Figure 23.1 The sequence of calcification of the wrist bones up to five years of age. My daughter bone age is at the end of 10th age but her age is 6 year and 10 months.
