下颌第一前磨牙3牙根3根管临床报告及文献回顾

下颌第一前磨牙由于根管形态比较复杂，牙根的变异情况较多，多根管的发生率较高，成功的根管治疗术除对根管系统进行严格清理、消毒与充填外，还需要对根管形态和解剖知识有正确的认识，否则可能出现遗漏根管，而导致根管治疗的失败。及时的冠方封闭也是根管治疗术成功要素之一。本文报告1例下颌第一前磨牙3牙根3根管的诊断、治疗、修复过程。...

Mandibular first premolar; Three root canals; Root canal therapy; Wedge.shaped defect; Dental restoration
The mandibular first premolar has complicated morphology of root canal,it has more variation which increases the incidence of multiple root canals.A successful root canal therapy not only need strict cleaning,disinfection and filling,but also need a correct understanding of root canal morphology and anatomy.Otherwise there might be a risk of missing canals that resulting the failure of the therapy.Also crown closure is one of the successful elements of root canal therapy.This is a case report accompanied by a review of the literature that shows the unusual anatomy of the mandibular first molar with three roots and three root canals.
