本文選題：錐體束CT(CBCT) + 上頜第一磨牙　； 參考：《實(shí)用口腔醫(yī)學(xué)雜志》2015年06期

【摘要】：目的:通過(guò)錐體束CT(CBCT)成像系統(tǒng)分析新疆維吾爾族成人上頜第一磨牙形態(tài)特征和上頜第一磨牙近中頰根根管形態(tài)及第二根管(MB2)的發(fā)生率。方法:選擇體檢且上頜牙列完整的100名維吾爾族成人進(jìn)行CBCT掃描,測(cè)量雙側(cè)上頜第一磨牙牙根的長(zhǎng)度,觀察髓底形態(tài)、近頰根根管形態(tài),按照J(rèn)in Hee Lee評(píng)價(jià)標(biāo)準(zhǔn)進(jìn)行分類。統(tǒng)計(jì)MB2根管的發(fā)生率及男女發(fā)生比率差異。結(jié)果:200顆上頜第一磨牙中3根3根管者154顆(77%),3根4根管42顆(21%),3根5根管2顆(1%),4根6根管和7根管各1顆(各0.5%)。近頰根管形態(tài)以Ⅰ、Ⅱ、Ⅲ、Ⅳ、Ⅴ型各占77%,13.5%、9%、0和0.5%男性和女性MB2根管發(fā)生率分別為22.32%和21.2%(P=0.901)。結(jié)論:維吾爾人上頜第一磨牙MB2發(fā)生率約22%,無(wú)性別差異,其形態(tài)以Ⅰ型為主。
[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，
