Abstract：
Background Understanding root canal anatomy variations, particularly C-shaped canals, is crucial for successful endodontic treatment. This study used clinical and radiographic methods to assess the prevalence and characteristics of C-shaped canals in mandibular second molars in Western Maharashtra. Materials and methods This prospective study was conducted in the western region of Maharashtra, India. The samples included patients requiring endodontic treatment for mandibular second molars. Clinical evaluation was conducted using a surgical endodontic microscope and cone beam computed tomography (CBCT) imaging. Inclusion and exclusion criteria ensured the selection of a focused and homogeneous sample. Data analysis included assessment of unilateral/bilateral occurrence, canal distribution, and cross-sectional characteristics. Results Out of 200 mandibular second molars, 7.5% exhibited C-shaped root canals, with no significant gender differences. Canal distribution varied across coronal, middle, and apical levels, with prevalent configurations being C1, C2, C3, and C4. No significant differences were observed in canal distribution based on root levels. No significant gender differences were found in the presence of grooves on the root surfaces. Conclusion This study provides valuable insights into the prevalence and characteristics of C-shaped canals in mandibular second molars in Western Maharashtra. Further research into histological and genetic aspects can enhance our understanding, leading to improved treatment strategies for complex root canal anatomy variations.
摘要：
背景了解根管解剖变异，特别是C形运河，对于成功的牙髓治疗至关重要。这项研究使用临床和影像学方法来评估西马哈拉施特拉邦下颌第二磨牙C形管的患病率和特征。材料和方法这项前瞻性研究是在马哈拉施特拉邦西部地区进行的，印度。样本包括需要牙髓治疗下颌第二磨牙的患者。使用外科牙髓显微镜和锥形束计算机断层扫描（CBCT）成像进行临床评估。纳入和排除标准确保选择集中且均匀的样品。数据分析包括评估单侧/双侧发生，运河分布，和横截面特征。结果200颗下颌第二磨牙,7.5%表现为C形根管，没有明显的性别差异。运河分布在整个日冕中变化，中间,和顶端水平，普遍的配置是C1、C2、C3和C4。根据根部水平，在根管分布中未观察到显着差异。在牙根表面上存在凹槽的情况下，没有发现明显的性别差异。结论本研究对西马哈拉施特拉邦下颌第二磨牙C形管的患病率和特征提供了有价值的见解。对组织学和遗传方面的进一步研究可以增强我们的理解，导致复杂根管解剖变异的改进治疗策略。
