Dental trauma is a common injury observed at dental practices that normally occurs in young patients. It especially affects the anterior teeth, although trauma to the posterior teeth can also be observed frequently when caused by high-impact trauma and masticatory forces. Horizontal root fracture in the posterior teeth is even more rare and involves a more specific type of trauma. This article reports the case of a second molar root fracture that happened during the removal of an impacted wisdom tooth. The patient had no discomfort associated with the event, and the tooth had no change in sensibility or mobility during follow-up. Seven months after the fracture, there was complete radicular healing even though no treatment was given.
牙外伤是牙科诊所常见的损伤，通常发生在年轻患者身上。它尤其影响前牙，不过当由高冲击力创伤和咀嚼力导致时，后牙创伤也较为常见。后牙水平根折更为罕见，且涉及更特殊类型的创伤。本文报告了一例在拔除阻生智齿过程中发生的第二磨牙根折病例。患者在该事件中无不适，且在随访期间牙齿的感觉和松动度均无变化。骨折七个月后，即使未进行治疗，牙根也实现了完全愈合。
