目的研究不同性别不同地区青少年骨性Ⅰ类错颅面部软组织厚度的性别差异。方法选取郑州地区恒牙初期骨性Ⅰ类错青少年100例,男50例,平均年龄(13.64±0.53)岁,女50例,平均年龄(14.36±0.66)岁。对其头颅侧位片行软组织厚度测量,对所测得数据采用两独立样本检验。结果郑州地区不同性别青少年鼻根点厚度(Ns-N)、鼻底厚度(Sn-A’)差异有统计学意义(P<0.05);与西安地区同性别间相比较,男性额厚(G’)、鼻低厚(Sn-A)、下唇凹厚(B-B’)、颏厚(Pos-Pog)差异有统计学意义(P<0.05),女性男性额厚(G’)、鼻根点厚(Ns-N)、下唇凹厚(B-B’)、颏厚(Pos-Pog)差异有统计学意义(P<0.05)。结论青少年骨性Ⅰ类错颅面部软组织厚度存在显著性别差异和地区差异。
Objective To study the sex differences in the soft tissue thickness of craniofacial skull base class Ⅰ malocclusion in different sexes. Methods 100 cases of skeletal Class Ⅰ malocclusion in Zhengzhou early permanent dentition were selected, including 50 males (mean age 13.64 ± 0.53) and 50 females (mean age 14.36 ± 0.66). The thickness of the soft tissue of its lateral cranial line measurement, the measured data using two independent sample test. Results There were significant differences in nasal root thickness (Ns-N) and nasal thickness (Sn-A ’) between different genders in Zhengzhou (P <0.05) (P <0.05), the male frontal thickness (G ’), the thickness of lower lip (B-B’ There were significant differences in Ns-N, B-B ’and Pos-Pog between the two groups (P <0.05). Conclusions There are significant gender differences and regional differences in the soft tissue thickness of the craniofacial region in skeletal Class Ⅰ malocclusion in adolescents.
