To evaluate the prevalence of C-shaped root canals in mandibular molars using cone beam computed tomography (CBCT) in a subpopulation of Central India.
CBCT scans of patients from diagnostic imaging center were selected in accordance with the criteria given by Fan . (2004) for C-shaped canals. A total of 238 CBCT scans fulfilled the inclusion criteria and thereby divided into two groups: Group 1: Images showing C-shaped canal configuration in mandibular second molars. Group 2: Images showing C-shaped canal configuration in mandibular third molars. The frequency and distribution of canals and their configuration along with the position of lingual/buccal grooves in the images were evaluated, and the data was analyzed.
CBCT evaluation showed that 9.7% of second molars and 8% of third molars had C-shaped canals. A prominent buccal groove was seen in these teeth. The data showed a significant difference ( = 0.038) for the presence of such anatomy on the right side for mandibular third molars.
The study showed a significant prevalence of C-shaped canal configuration in the subpopulation studied.
使用锥形束计算机断层扫描（CBCT）评估印度中部一个亚人群下颌磨牙C形根管的患病率。
根据Fan（2004年）给出的C形根管标准，从诊断成像中心选取患者的CBCT扫描图像。共有238张CBCT扫描图像符合纳入标准，因此分为两组：第1组：显示下颌第二磨牙C形根管形态的图像。第2组：显示下颌第三磨牙C形根管形态的图像。评估图像中根管的频率、分布及其形态以及舌侧/颊侧沟的位置，并对数据进行分析。
CBCT评估显示，9.7%的第二磨牙和8%的第三磨牙有C形根管。在这些牙齿中可见明显的颊侧沟。数据显示下颌第三磨牙右侧存在这种解剖结构有显著差异（P = 0.038）。
该研究表明，在所研究的亚人群中，C形根管形态的患病率较高。
