摘要: 目的 通过透明牙标本法、锥体束CT扫描法,研究山东地区人下颌第一前磨牙根管系统的形态。方法 从山东各地市医院口腔科选取符合条件的离体下颌第一前磨牙共计164颗为研究对象,肉眼观察其牙根外形,记录有根面凹陷牙齿的数量,通过透明牙标本法采用Vertucci’s分类法观察根管系统形态。选取山东大学口腔医院放射科的锥体束CT(cone-beam CT,CBCT)影像资料中304颗山东人下颌第一前磨牙的影像,观察根管系统形态。结果 透明牙标本法中,164颗离体牙,有2颗为双根牙,162颗为单根牙,双根牙检出率为1.22%;162颗单根牙的根管中,Ⅰ型根管检出率82.72%,Ⅲ型根管检出率为1.23%,Ⅳ型根管检出率为3.09%,Ⅴ型根管检出率为12.96%,Ⅱ、Ⅵ、Ⅶ、Ⅷ型根管检出率为0。164颗离体牙透明牙标本法的双根管检出率为18.29%;36颗离体牙有根面凹陷,其中21颗牙根管数目为单根管,其余15颗为双根管,有根面凹陷的离体牙双根管检出率41.67%;锥体束CT扫描304颗下颌第一前磨牙,55颗牙为双根管,双根管检出率为18.09%。结论 山东地区人下颌第一前磨牙双根管出现率比较高,根管形态比较复杂,临床治疗时需注意,可采取多种辅助手段,确定根管形态。

Abstract: Objective To study the anatomical features of root canal system of mandibular first premolar in Shandong Province. Methods A total of 164 qualified mandibular first premolars were selected from departments of stomatology in several cities of Shandong Province to analyze the root types. The number of the teeth with root concavity was recorded. The root systems were analyzed with the transparent tooth specimen method and Vertucci's classification. Altogether 304 mandibular first premolar images were collected from the cone-beam CT image data of Department of Radiology, Stomatological Hospital of Shandong University. Results According to the transparent tooth specimen method, of the 164 teeth, 2 (1.22%) were double-rooted and 162 single-rooted. In the 162 singled-rooted teeth, typeⅠsystem accounted for 82.72%, type Ⅲ 1.23%, type Ⅳ 3.09%, type Ⅴ 12.96%, type Ⅱ, Ⅵ, Ⅶ, and Ⅷ system 0. The detection rate of double root-canal was 18.29%. Among the 36 teeth with root concavity, 21 had single and 15(41.67%) had double root-canal. From the results of cone-beam CT scan, 55(18.09%) of the teeth had double root-canal. Conclusion The rate of multiple root-canal in the mandibular first premolar root-canal of Shandong population is relatively high, which should be paid more attention by dentists.
