摘要:
目的：研究维吾尔族与汉族不同矢状骨面型人群前牙冠根比。方法：选取符合纳入标准的236例CBCT影像资料，按照 矢状骨面型分为4组。A组：骨性Ⅰ类（汉族30例，维吾尔族30例），B组：骨性Ⅱ类1分类（汉族30例，维吾尔族30例）；C 组：骨性Ⅱ类2分类（汉族30例，维吾尔族28例）；D组：骨性Ⅲ类（汉族30例，维吾尔族28例）。测量上下颌前牙根长、 冠长，计算冠根比，并进行统计学分析。结果：①B组中，维吾尔族与汉族上颌切牙、下颌尖牙冠根比差异有统计学意义 （P＜0.05）；C组中，维吾尔族与汉族下颌侧切牙冠根比差异有统计学意义（P＜0.05）。②在汉族四组比较中，D组上下颌 前牙冠根比大于A、B组，C组上颌前牙冠根比大于B组，C组上颌切牙冠根比大于A组（P＜0.05）；在维吾尔族四组比较中，D 组上下颌前牙冠根比大于A、B组，C组上颌前牙冠根比大于B组，C组上颌切牙冠根比大于A组（P＜0.05）。结论：维吾尔族 与汉族在骨性Ⅱ类1分类上颌切牙、下颌尖牙和骨性Ⅱ类2分类的下颌侧切牙冠根比具有差异性，种族是影响上下颌前牙冠根比的一个重要因素。维吾尔族、汉族的骨性Ⅲ类及骨性Ⅱ类2分类冠根比相对较大，正畸医生应根据冠根比设计矫治方案， 并在矫治过程中密切关注冠根比变化。
Abstract:
Objective To study the characteristics of crown-root ratio of upper and lower anterior teeth of Uighur and Han patients with different sagittal skeletal types. Methods A total of 236 patients with Cone beam CT(CBCT) imaging data meeting the inclusion criteria were selected and divided into 4 groups according to sagittal skeletal plane type. Group A:skeletal class Ⅰ(Han 30 cases, Uighur 30 cases),Group B: skeletal Class Ⅱ1 (Han 30 cases, Uighur 30 cases), Group C: skeletal Class Ⅱ2 (Han 30 cases, Uighur 28 cases), Group D: skeletal Class Ⅲ(Han 30 cases, Uighur 28 cases).The length of root and crown of upper and lower anterior teeth were measured with CBCT, and the crown-root ratio was calculated, and statistical analysis was carried out. Results ①There were statistically diff erent ratios of maxillary incisors and mandibular canines in group B ,and mandibular lateral incisors in group C between Uighur and Han people. ②Both in Uighur and Han nationality, the crown root ratio of upper and lower anterior teeth in group D was higher than that in group A and group B (P＜0.05), the crownroot ratio of upper anterior teeth in group C was higher than that in group B (P＜0.05), and the crown-root ratio of upper incisor teeth in group C was higher than that in group A (P＜0.05). Conclusion There are statistical diff erence ratio of maxillary incisors and mandibular canines in skeletal Class Ⅱ1 , and mandibular lateral incisors in skeletal Class Ⅱ2 between Uighur and Han people. Race is an important factor aff ecting the crown-root ratio of upper and lower anterior teeth. Both in Uighur and Han nationality, the crown-root ratio of skeletal Class Ⅲ and Class Ⅱ2 are relatively high. The crown-root ratio should be considered in orthodontic design and the correction process.
