摘要： 下颌第一前磨牙根管系统复杂多变,双根管、多根管都有一定的发生率,临床医师应熟悉掌握其根管系统的正常解剖及其可能出现的变异。本文报告2例左下颌第一前磨牙双根管(2-2型,Verlucci分类)及多根管(1-3型,Verlucci分类)变异,可分为颊根、舌根及位于两者之间的正中根管,并结合相关文献,对下颌第一前磨牙双根、多根的诊断及探查进行分析,以期减少根管遗漏,确保完善的根管治疗。

Abstract: Mandibular first premolars have complex root canals. Double root canals and three root canals usually happen. Clinicians should be aware of the normal anatomy of root canal system and vigilant about the possibility of canal variation. In this paper, two cases of mandibular first premolars with double (2-2, Verlucci) and three(1-3,Verlucci) root canals were reported. The root canal type and its incidence were discussed. Clinicians should carefully explore to confirm the existence of variation and avoid missed canals, which are necessary for a successful root canal therapy.

Key words: Mandibular first premolar, Canal variation, Root canal
