Extraoral inverted teeth eruption: a case report.

A 14-year-old female presented with extraoral inverted eruption of left mandibular permanent molars 18 and 19 at the lower left inferior border of the mandible. Both the teeth started erupting 1 year after an extraoral surgical intervention for a discharging sinus 6 years ago. The subsequent eruption to the extraoral position of the permanent molars at the inferior border of mandible may be the result of the previous surgical procedure or pathology related to the abnormally positioned teeth. This case presents an infrequent complication affecting the adjacent permanent teeth.
