Current publications have demonstrated that the third molar not erupted increases the risk of mandibular angle fracture, and may prevent the condylar fracture. The aim of this study is to report through a case study the involvement of a third molar in mandibular fracture line. Patient, male, 16 years old, attended at the Service of Oral and maxilofacial Surgery and Traumatology of the Hospital Estadual de Emergência e Trauma Senador Humberto Lucena, at João Pessoa-PB, car accident victim. Clinically presented with limitation of mouth opening, occlusal disharmony and pain on palpation. The radiographic examination showed an image compatible with left mandibular angle fracture, with involvement of the element 38 in the fracture line. The treatment consisted of extra-oral surgery, performing reduction and fixation of fractured segments with the use of dynamic compression plate.
