This study found that bifid mandibular canals occurred in 0.35% of patients, exclusively in women. These double mandibular canals are an anatomical variant identified through dental radiography.

Area of Science:

  • Dentistry
  • Anatomy
  • Radiology

Background:

  • The mandibular canal is a critical anatomical structure housing the inferior alveolar nerve and vessels.
  • Anatomical variations of the mandibular canal, such as bifid canals, can impact dental procedures.

Purpose of the Study:

  • To determine the incidence and characteristics of bifid mandibular canals.
  • To investigate the presence of double mandibular canals in a patient population.

Main Methods:

  • Retrospective analysis of 2012 panoramic radiographs from dental patients.
  • Utilized panoramic radiography and computed tomography for identification and confirmation.

Main Results:

  • Identified 7 suggestive images of bifid canals on panoramic radiographs.

  • Confirmed the anatomical variant in 2 out of 3 patients via computed tomography.
  • Observed an incidence of 0.35% for bifid canals.

    • Conclusions:

    • Bifid mandibular canals are a rare anatomical variant.
    • All identified cases of bifid mandibular canals were in female patients.
    • Understanding this variant is crucial for dental treatment planning and minimizing complications.
