【摘要】：目的：建立新疆維吾爾族正常牙合青少年顱面軟硬組織X線頭影測量均值和標準差，并探討其性別差異以及同性別維吾爾族、漢族、哈薩克族青少年顱面軟硬組織結(jié)構(gòu)的民族差異，從而驗證維爾族、漢族、哈薩克族青少年顱面測量值有差異的假設(shè)。方法：對3380名新疆烏魯木齊市維吾爾族中小學(xué)生進行普查，從中選取正常牙合青少年84名（男41例，女43例，年齡在12～18歲，平均年齡15.4歲），拍攝牙尖交錯位時頭顱定位側(cè)位片，并用北京醫(yī)科大學(xué)口腔正畸科提供的頭顱測量軟件（華正頭影測量軟件）進行定點和分析。結(jié)果：1)得到了新疆維吾爾族正常牙合青少年顱面軟硬組織頭影測量分析均值和標準差，統(tǒng)計學(xué)分析表明，維吾爾族男女青少年除前顱底（S-N）和后顱底長度（S-Ar）以外的所有骨性和牙性結(jié)構(gòu)測量值均無統(tǒng)計學(xué)差異，但軟組織結(jié)構(gòu)除S1-LL外都存在顯著的統(tǒng)計學(xué)差異。2）與同性別漢族青少年比較，維吾爾族青少年除ANB,H角,MP/FH（男）,Z角（男）,SNA(女),OP/SN(女),MP/SN（女）（P＞0.05）無統(tǒng)計學(xué)差異外，其余測量項目均有統(tǒng)計學(xué)差異。3)與同齡同性別哈薩克族比較，維吾爾族青少年除L1/MP, L1/NB, Pg-NB, OP/SN, MP/SN, SNB（女)無統(tǒng)計學(xué)差異外，其余的測量項目均有統(tǒng)計學(xué)差異(P＜0.05)。結(jié)論：維吾爾族男性青少年的前顱底和后顱底長度以及上下唇突度均大于女性青少年，與同齡同性別漢族及哈薩克族青少年比較，維吾爾族青少年的牙弓突度小，，上下切牙直立，頦部較突，髁狀突位置較靠前，呈Ⅲ類面型特征，具有明顯的民族特征。
[Abstract]:Objective: to establish the mean value and standard deviation of cephalometric measurements of craniofacial soft and hard tissue in Xinjiang Uygur adolescents with normal occlusal, and to explore the gender difference and the same sex Uygur and Han nationality. The differences of craniofacial soft and hard tissue structure among Kazakh adolescents were verified by the hypothesis that there were differences in craniofacial measurements among the adolescents of the Weier nationality, Han nationality and Kazakh nationality. Methods: a total of 3380 Uygur primary and middle school students in Urumqi, Xinjiang, were investigated and 84 normal occlusion adolescents (41 males and 43 females, aged 1218 years with an average age of 15.4 years) were selected. The lateral position of the head was taken in the interlaced position of the cusp, and the fixed point and analysis were performed with the head measurement software provided by the Department of Orthodontics, Beijing Medical University (Huazheng cephalometric software). Results: 1) the average value and standard deviation of cephalometric analysis of craniofacial soft and hard tissue in Xinjiang Uygur normal adolescents were obtained. There was no significant difference in bone and tooth structure between male and female Uygur adolescents except for the anterior skull base (S-N) and posterior skull base length (S-Ar). But there were significant statistical differences in soft tissue structure except S1-LL. 2) compared with Han nationality adolescents of the same sex, Uygur adolescents had significant differences except ANB,H angle, MP/FH (male), Z angle (male), SNA (female), OP/SN (female), male), Z angle (male), SNA (female), OP/SN (female). There was no statistical difference in MP/SN (female) (P > 0. 05), but there were statistical differences in other measurement items. 3) compared with Kazakh of the same age and gender, Uygur adolescents except L1 / MPP, L1 / NB, Pg-NB, OP/SN,. There was no statistical difference in MP/SN, SNB (female), but there was statistical difference in other items (P < 0. 05). Conclusion: the length of anterior skull base and posterior skull base and the degree of upper and lower lip protrusions of male Uygur adolescents are larger than those of female adolescents. Compared with Han nationality and Kazak adolescents of the same age, Uygur adolescents have lower dental arch protrusions. The upper and lower incisors are erect, the chin is protruding and the condyle position is forward.
