The purpose of this study was to use cone bar CT to investigate the root trench morphology of two-hundred mesiobuccal permanent first molars in the maxilla.
The distobuccal and palatal roots were removed at the furcation in 250 maxillary first molars. The mesiobuccal roots were then imaged using cone beam computed tomography on all specimens. The specimens were analyzed and compared to one another." This study looked into the following factors. How Many Canals There Are and What Shape Those Canals Take Errors such as lateral canals, apical delta, calcified segments, and others.
Vertucci's trench configuration, kinds I, II, III, IV, V, and VII, were seen in 30%, 20%, 5%, 6%, 7%, and 2.5% of the teeth, respectively. Calcified sections were found in the coronal third of the MB1 trench for eight of the samples, and in the central third for two of the samples. The MB1 trench did not have any calcifications at its very end. The coronal 33 percent of the MB2 trench was calcified in eight samples, but no calcifications were seen in the middle or upper thirds.
Noninvasively and with little radiation, a cone beam CT scan can help you learn about your root canal setup.
本研究的目的是使用锥形束CT研究上颌200颗近中颊侧第一恒磨牙的根管形态。
在250颗上颌第一恒磨牙的根分叉处去除远中颊根和腭根。然后对所有标本的近中颊根进行锥形束计算机断层扫描成像。对标本进行分析并相互比较。本研究考察了以下因素。根管数量及其形态 侧支根管、根尖分歧、钙化段等错误情况。
分别在30%、20%、5%、6%、7%和2.5%的牙齿中观察到维尔图奇根管形态,即I、II、III、IV、V和VII型。在8个样本的MB1根管冠三分之一处发现钙化段,在2个样本的根管中三分之一处发现钙化段。MB1根管根尖处未发现钙化。在8个样本中,MB2根管冠三分之一处钙化,但在中三分之一或上三分之一处未发现钙化。
锥形束CT扫描可无创且辐射小地帮助了解根管结构。
