A successful endodontic treatment depends on a comprehensive knowledge of the morphology of canal and its variations, an appropriate access cavity, proper cleaning and shaping and adequate root canal filling. The present study was carried out to evaluate the root canal morphology of permanent maxillary first molars in an Iranian population.
In this study, 80 extracted permanent maxillary first molars from a population in Rafsanjan, Iran were collected. Root canal morphology was evaluated by clearing technique under stereomicroscope under 40× magnification. A combination of Vertucci's and Sert and Bayirli's classifications were used to determine the root canal types. Data were analyzed by SPSS 18 software using descriptive statistics.
All palatal roots and almost all distobuccal roots had type I configuration. Ten different types of root canal system were found in mesiobuccal roots, among which type I was the most common (38.75%), followed by type II, IV, V, VI, IX, XV, XVI=XIX and VII, respectively
The mesiobuccal roots of permanent maxillary first molar had the most complex root configuration.
成功的根管治疗取决于对根管形态及其变异的全面了解、合适的开髓腔、恰当的清理和成形以及充分的根管充填。本研究旨在评估伊朗人群中恒上颌第一磨牙的根管形态。
本研究收集了来自伊朗拉夫桑詹人群的80颗拔除的恒上颌第一磨牙。在体视显微镜下40倍放大倍数下通过透明技术评估根管形态。采用韦尔图奇分类法和塞尔特与巴伊里分类法相结合的方式来确定根管类型。使用SPSS 18软件进行描述性统计分析数据。
所有腭根和几乎所有远中颊根均为I型构型。在近中颊根中发现了10种不同类型的根管系统，其中I型最为常见（38.75%），其次分别为II型、IV型、V型、VI型、IX型、XV型、XVI = XIX型和VII型。
恒上颌第一磨牙的近中颊根具有最复杂的根管形态。
