摘　　要：目的:观察Ⅴ型根管的牙位分布。方法:选取2013-12—2015-02进行CBCT检查的患者198例共2 984个牙为研究对象,对具有Ⅴ型根管的牙位进行观察、记录和分析。结果:1 306个前牙中,下颌切牙和尖牙Ⅴ型根管出现率分别为3.36%和2.24%,而上颌前牙均未出现;897个前磨牙中,Ⅴ型根管出现比率最高的为上颌第二前磨牙5.83%,其次为下颌第一前磨牙4.46%;781个磨牙中,Ⅴ型根管出现率第二磨牙(5.88%)较第一磨(0.52%)牙高。结论:Ⅴ型根管在较多牙位都可能出现,上颌第二前磨牙、下颌第一前磨牙以及第二磨牙出现Ⅴ型根管的可能性最高。AIM： To investigate the distribution of Vertucci type Ⅴ canal configuration. METHOD： 2984 teeth in 198 patients were examined by cone-beam computed tomographic（ CBCT） imaging and the distribution of Vertucci type Ⅴ canal configuration was recorded and analyzed. RESULTS： Type Ⅴ canal configuration was found in both mandibular incisors（ 3. 36%） and canines（ 2. 24%）,but not in maxillary anterior teeth. Of the premolars,the prevalence in the second maxillary premolars（ 5. 83%） was the highest,followed by the first mandibular premolars（ 4. 46%）. Of the molars,type Ⅴ canal configuration was frequently found in the second molars（ 5. 88%）,but rarely in the first molars（ 0. 52%）. CONCLUSION： Type Ⅴ canal configuration can be found in many teeth,especially in maxillary second premolars,mandibular first premolars and second molars.
