Numb chin syndrome associated with vertical root fracture and odontogenic infection.
Numb chin syndrome (NCS) is a multifactorial neuropathic disorder associated with paresthesia to the chin, lip, and oral mucosa, particularly arising as a sequela to various dental-related procedures or infections in the mandible. Timely elucidation of the underlying etiology is of paramount importance as the presentation of NCS could serve as a harbinger of malignancy or metastatic disease. This report describes an unusual case of NCS developing synchronously with a vertical root fracture and odontogenic infection in a mandibular first molar. Clinicians should consider the inclusion of a vertical root fracture as plausible cofactor for the development of NCS.
