A child's skeletal age is best determined by:
a. assessment of dentition.
b. assessment of height over time.
c. facial bone development.
d. radiographs of the hand and wrist.
ANS: D
The most accurate measure of skeletal age is radiologic examinations of the growth plates. These are the epiphyseal cartilage plates. Radiographs of the hand and wrist provide the most useful screening to determine skeletal age. Age of tooth eruption has considerable variation in children. It would not be a good determinant of skeletal age. Assessment of height over time will provide a record of the child's height but not skeletal age. Facial bone development will not reflect the child's skeletal age, which is determined by radiographic assessment.
