Abstract:

Root canal therapy of mandibular first premolar is challenging for there are some variations in mandibular first premolar root canal. And it is easy to fail when there are some tiny missing root canals. This article reported a mandibular first premolar with apical furcation which was found by the combined application of X-ray and CBCT. This article also focuses on root canal exploration and instrumentation, in order to provide evidence for treatment of mandibular first premolar.

Key words: Mandibular first premolar, Apical furcation, Cone beam computed tomography, Root canal preparation, Root canal therap
