Abstract:

BACKGROUND: Hand-wrist bone maturation as the gold standard for evaluating of bone age has been widely used in the clinical work, but the cervical vertebrae maturation as a new bone age evaluation, with its economic, simple and strong clinical operability has get widespread attention.
OBJECTIVE: To investigate the correlation between adolescents’s hand-wrist bone maturation and cervical vertebrae maturation in Urumqi region, and to provide valid reference index for making diagnosis and treatment plan in orthodontics.
METHODS: The lateral cephalograms and hand-wrist radiographs of the 96 cases (34 males, 62 females, 9-15 years of age) were taken before orthodontics treatment. The quality of X-ray image was good, and all the observation indicators were clearly visible without overlapping images. Cervical vertebrae maturation and hand-wrist bone maturation were evaluated.
RESULTS AND CONCLUSION: The correlation coefficient between cervical vertebrae maturation and hand-wrist bone maturation was high (r=0.703, P < 0.01 for males and r=0.728, P < 0.01 for females respectively). The cervical vertebrae maturation and the hand-wrist bone maturation on lateral cephalogram were valid indicators on orthodontic practice to evaluate preciously patients’ state of development and growth. And the cephalogram can avoid additional X-ray radiation that patients received, reduce the economic burden of patients.
