摘要
目的:采用锥形束CT(CBCT)观察下颌切牙根管解剖形态结构,为临床治疗提供解剖学依据。方法:收集300例患者的1136颗下颌切牙的锥形束CT图像资料,统计分析牙根数目、根管形态及双根管牙在各年龄组、男女性别及左右侧牙位间的发生情况。结果:1136颗下颌切牙全部为单根牙。下颌中切牙、侧切牙双根管的发生率分别为11.11%、19.38%,下颌中、侧切牙双根管在男女性别和左右侧牙位间的发生率比较无统计学差异(P>0.05)。按照Vertucci根管分型,下颌切牙共观察到5种根管类型,其中以Ⅰ型(1-1)为主,其次是Ⅲ型(1-2-1),Ⅴ型(1-2)的发生率最低,其发生率分别为84.68%,12.24%,0.35%。结论:下颌切牙根管的解剖形态结构复杂,锥形束CT影像可为临床根管治疗术提供可靠的依据。
Objective:This paper was to investigate the root canal morphology of mandibular incisors by cone-beam computed tomography.Methods:A total of 1136 CBCT images of mandibular incisors from 300 patients were collected retrospectively.The number of roots and root canals,root canal morphologies were analyzed.Results:All the mandibular incisors were single root,the prevalence of two root canals in mandibular central incisors,lateral incisors were 11.11%,19.38%,respectively.There was no significant correlation of root canal number between male and female and between left and right(P>0.05).Five Vertucci root canal configurations were observed,and type I(84.68%)was mostfrequent,followed by typeⅢ(12.24%),and typeⅤ(0.35%)was the lowest.Conclusion:The root canal morphology of mandibular incisors are quite diversified and the application ofCBCT helps to facilitate endodontic treatment.
