Abstract
OBJECTIVES: The purpose of this study is to evaluate the compatibility of ultrasonographic data with hand-wrist radiographs taken to determine the extent of pubertal growth and bone age in patients and investigate the usability of ionizing radiation-free ultrasonography instead of conventional radiography.
METHODS: In this study, a total of 120 children from 10 to 17 years old (mean age was 168 months ± 27.5 months) were treated with routine radiographs before orthodontic treatment, and ultrasonographic imaging was performed on the wrists the same day. Researchers examined the phalanges, sesamoid bone, and radial bone distal epiphysis-diaphysis comparatively in each patient by both imaging methods and statistical evaluation.
RESULTS: There was no statistically significant difference between conventional radiography and USG values at 13 points except for PP1 (proksimal phalanges of the first finger), PP2 (proksimal phalanges of the second finger), and radial epiphysis (p > .05). PP1, PP2, and radial epiphysis showed a statistically significant difference (p < .05). The CBA (bone age obtained from conventional radiographs) of the females was found to be larger than their CA (chronological age) and their UBA (ultrasonographic bone age). For males; the means of the CBA, UBA and CA values close to each other. In females and males; there was a strong correlation between the CA, the UBA and the CBA (p < .01).
CONCLUSIONS: Ultrasonography gives detailed information about epiphyseal diaphysis relations. It can be used as an alternative to conventional radiography in the detection of bone age and pubertal growth, owing to the absence of ionizing radiation.
