目的探讨女性儿童下颌后缩患者的骨成熟度与Ⅰ类骨型错畸形患者比较是否具有差异性,分析下颌后缩与骨发育成熟的早晚是否存在相关性。方法随机选择下颌后缩28例和Ⅰ类骨型错患者47例,均为女性,年龄10～12.9岁,测量其颈椎骨龄,比较两组间颈椎骨龄以及颈椎骨龄年龄差有无差异性。结果下颌后缩组平均颈椎骨龄为11.40,平均年龄骨龄差为0.35,Ⅰ类骨型组平均颈椎骨龄为11.78,平均年龄骨龄差为0.56,两组间颈椎骨龄和年龄骨龄差均无显著性差异,下颌后缩组患者的颈椎骨发育相对于Ⅰ类骨型组患者有轻微推后的趋势。结论下颌后缩与Ⅰ类骨型错畸形女童的骨龄没有显著性差异,下颌后缩与骨骼发育的早晚不存在明显的相关性。
Objective To investigate whether bone maturity in patients with mandibular retrusion in female children is different from that in patients with type Ⅰ malocclusion and whether there is a correlation between mandibular retrusion and early or late bone maturation. Methods Totally 28 patients with mandibular rupture and 47 patients with type Ⅰ malocclusion were randomly selected. All patients were female, aged from 10 to 12.9 years old. The cervical spine age was measured. The differences of cervical spine age and cervical spine age were compared between the two groups. Results The mean cervical spine age was 11.40 for the mandibular retrusion group, 0.35 for the average age. The mean cervical spine age was 11.78 for the Ⅰ group and 0.56 for the average age. There was no significant difference in the age of the cervical spine between the two groups , And the development of cervical vertebrae in the mandibular retrusion group had a slight postponement trend compared with the patients in the type Ⅰ osteoporosis group. Conclusion There is no significant difference in the bone age between mandibular retrusion and Ⅰ type osteoporotic deformity girls. There is no significant correlation between mandibular retrusion and early or late skeletal development.
