Abstract
BACKGROUND
Successful endodontic treatment requires a significant knowledge of root canal anatomy. The aim of this study was to evaluate the root and root canal number of permanent teeth among the Moscow population using cone-beam computed tomography (CBCT) scanning.
MATERIALS AND METHODS
300 CBCT images of subjects were analyzed to study the anatomy of roots and root canal system of each tooth. The collected data were analyzed using IBM SPSS statistics software 22.0 version.
RESULTS
The maxillary incisors and canines had one root with one canal in 100%. Maxillary premolars had one root with one or two canals and two roots with two canals, while mandibular premolars were single-rooted with one or two canals. Maxillary first and second molar had three separated roots, and the prevalence of four canals was more often in first molars. Mandibular molars had two roots with different number of canals.
CONCLUSION
The root canal system varies greatly among populations and even in different individuals within the same population; thus, using CBCT scanning is an effective technique in investigating the root canal system.
摘要
背景
成功的牙髓治疗需要对根管解剖结构有深入了解。本研究的目的是使用锥形束计算机断层扫描（CBCT）评估莫斯科人群恒牙的牙根和根管数量。
材料与方法
分析300例受试者的CBCT图像，以研究每颗牙齿的牙根和根管系统解剖结构。使用IBM SPSS统计软件22.0版本对收集的数据进行分析。
结果
上颌切牙和尖牙100%为单根单管。上颌前磨牙有单根单管或双管以及双根双管，而下颌前磨牙为单根单管或双管。上颌第一和第二磨牙有三个分开的牙根，第一磨牙四根管的发生率更高。下颌磨牙有两个牙根，根管数量不同。
结论
根管系统在不同人群之间甚至同一人群中的不同个体之间差异很大；因此，使用CBCT扫描是研究根管系统的有效技术。
