An unusual route of odontogenic infection from the mandible to the orbit through the facial spaces, resulting in blindness: a rare case report.

Orbital infection is a rare complication of odontogenic infections, mostly originating from maxillary teeth. In our case, we present one of the unusual routes by which an odontogenic infection of a lower molar tooth has spread into the orbit. A 67-year-old uncontrolled diabetic patient was referred to our hospital with a complaint of a swollen right masseteric region and orbital infection following a dental procedure on the right mandibular third molar.
