Aim: This case report aims to demonstrate a rare mandibular canal (MC) variation, presenting right trifurcation and left bifurcation through Cone-Beam Computed Tomography (CBCT).

Case report: A 26-year-old female patient with no systemic disorders was referred for surgical removal of the lower third molars due to the presence of painful symptoms. CBCT was requested to evaluate the relationship between third molars and the mandibular canal and to guide the surgical planning. Tomographic volume was analyzed through the Sidexis software (Sirona Dental Systems, Bernsheim, Germany). During the analysis of tomographic sections, it was possible to observe the presence of bilateral MC variations. Bifurcation of the right MC and trifurcation of the left MC were observed.

Conclusion: The present report highlighted the importance of CBCT for the diagnosis of anatomical changes, such as MC trifurcation.
