【摘要】：目的:通过锥体束CT(CBCT)成像系统分析新疆维吾尔族成人上颌第一磨牙形态特征和上颌第一磨牙近中颊根根管形态及第二根管(MB2)的发生率。方法:选择体检且上颌牙列完整的100名维吾尔族成人进行CBCT扫描,测量双侧上颌第一磨牙牙根的长度,观察髓底形态、近颊根根管形态,按照Jin Hee Lee评价标准进行分类。统计MB2根管的发生率及男女发生比率差异。结果:200颗上颌第一磨牙中3根3根管者154颗(77%),3根4根管42颗(21%),3根5根管2颗(1%),4根6根管和7根管各1颗(各0.5%)。近颊根管形态以Ⅰ、Ⅱ、Ⅲ、Ⅳ、Ⅴ型各占77%,13.5%、9%、0和0.5%男性和女性MB2根管发生率分别为22.32%和21.2%(P=0.901)。结论:维吾尔人上颌第一磨牙MB2发生率约22%,无性别差异,其形态以Ⅰ型为主。
[Abstract]:Objective: to analyze the morphological characteristics of maxillary first molar and the incidence of mesiobuccal root canal and second root canal of maxillary first molar in Uygur adults in Xinjiang by using the Cone tracheal CBCT imaging system. Methods: a total of 100 Uygur adults with complete maxillary dentition were selected for CBCT scanning. The root length of bilateral maxillary first molar was measured and the pulp floor morphology and buccal root canal morphology were observed and classified according to Jin Hee Lee evaluation criteria. The incidence of MB2 root canal and the difference between male and female were analyzed. Results of the 200 maxillary first molars, 154 had 3 canals and 4 canals, and 42 had 3 canals, 3 canals, 2 canals, 4 canals, 6 canals, and 7 canals, respectively. The morphology of proximal root canal was 鈪，
