With the advent of magnification, either by loupes or microscope, the astute clinician must be aware of recent literature that states that the mandibular first molar has a 1-15% chance of a fifth canal. This is a case report accompanied by a review of the literature that shows the unusual anatomy of the mandibular first molar.
