Abstract
The mandibular canal is a single canal that runs in the mandible carrying inferior alveolar neuro vascular bundle and splitting of the mandibular canal into in its course is rare occurrence. With the advent of 3-dimensional imaging modalities like computed tomography or cone-beam computed tomography better visualization becomes possible. As a result, more cases of this nature are being reported in the recent past giving rise to increased prevalence than in the past where two-dimensional imaging like digital panoramic tomography were dominating. This article also appreciates the radiological anatomy of three cases with bifurcation of the mandibular canal incidentally diagnosed in the cone-beam computed tomography and also discusses the clinical significance of this rare anatomical entity.
Highlights
The origins of the bifid mandibular canal can be comprehended by understanding its embryology
This development is followed in time by the fusion of the nerves. This theory would explain the as existence of double mandibular canals in some patients, secondary to incomplete fusion of these 3 nerves
Many authors say that Cone-beam Computed Tomography (CBCT) is a better imaging modality than DPT for spotting bifurcation of mandibular canal (BMC) in the mandible
