A 14-year-old girl suffered bilateral condylar fractures with an additional symphysis fracture of the mandible and multiple dental injuries due to fainting and ground-level fall. A dental panoramic radiograph image shows a sagittal corpus fracture (wide arrow) and bilateral condyle fractures (small arrows) of the mandible, which were more detectable with additional imaging. Fractures were treated by intermaxillary fixation and a soft diet. A fragmentary crown-root fracture was observed in the lower left first molar that was removed under general anaesthesia at primary fracture treatment. Additionally, crown fractures were observed in the upper right second premolar and lower right first molar. The lower left premolars did not respond to vitalometer after injury, which was partially explained by the fracture-related neurosensory disturbance in mandibular inferior nerve. Further dental follow-up revealed periapical signs of devitalization and the patient received root treatment to the lower second premolar 14 months after injury. Tooth loss was replaced with an implant at the end of the patient’s growth
