Abstract

This report presents the detection, characterisation, instrumentation and filling of complex canal configurations in the mesiobuccal (MB) root of maxillary first molars. Three patients were referred for root canal treatment in first maxillary molars. Medical history, age, sex and clinical findings were recorded. Intraoral periapical radiographs and cone beam computed tomography (CBCT) were used for diagnosis and pre-operative assessment. Using Ahmed et al. (2017) classification system, codes 3MaxM MB3-5-4-2 DB1-2-1 P1 (case 1), 3MaxM MB2-5-3-2 DB1 P1 (case 2) and 3MaxM MB1-4-2-1-2 DB1 P1 (case 3) were identified. Using the dental operating microscope, CBCT (if indicated) and troughing up to 3 mm allowed identification of more than three canals in the MB root of maxillary first molars. The coding system proposed by Ahmed et al. (2017) allows the classification of MB roots with highly complex canal configurations.

上颌第一磨牙中颊根复杂根管结构的检测、特征描述和处理:病例系列。
本报告介绍了上颌第一磨牙中颊(MB)根复杂根管结构的检测、特征描述、器械操作和充填。三位患者被转诊接受上颌第一磨牙根管治疗。记录了病史、年龄、性别和临床表现。口内根尖周X光片和锥形束计算机断层扫描(CBCT)用于诊断和术前评估。使用 Ahmed 等人(2017 年)的分类系统,确定了代码 3MaxM MB3-5-4-2 DB1-2-1 P1(病例 1)、3MaxM MB2-5-3-2 DB1 P1(病例 2)和 3MaxM MB1-4-2-1-2 DB1 P1(病例 3)。使用牙科手术显微镜、CBCT(如有必要)和最多 3 毫米的切槽,可以确定上颌第一磨牙 MB 根部有三个以上的根管。Ahmed 等人(2017 年)提出的编码系统可以对具有高度复杂牙管结构的 MB 根进行分类。

期刊介绍: The Australian Endodontic Journal provides a forum for communication in the different fields that encompass endodontics for all specialists and dentists with an interest in the morphology, physiology, and pathology of the human tooth, in particular the dental pulp, root and peri-radicular tissues. The Journal features regular clinical updates, research reports and case reports from authors worldwide, and also publishes meeting abstracts, society news and historical endodontic glimpses. The Australian Endodontic Journal is a publication for dentists in general and specialist practice devoted solely to endodontics. It aims to promote communication in the different fields that encompass endodontics for those dentists who have a special interest in endodontics.
