Traumatic injuries to maxillary anterior teeth are a common finding in children because of falls while playing. Sequelae of trauma to dental hard tissue include broken, lost, aspirated and swallowed teeth. One additional hazard is the embedding of fractured tooth fragments in the soft tissues, particularly in the lip. A 10-year-old male patient complained of pain in the lower lip. There was a history of trauma to the upper anterior tooth 10 months previously. Clinical examination showed scarring and discoloration over the lower lip, and the presence of a hard mass was felt on palpation. Intraoral examination revealed an Ellis and Davey class II fracture of number 11. A radiograph of the lip was taken, which showed a radiopaque structure similar to the shape of the missing tooth fragment. Under local anesthesia, the tooth fragment was removed successfully, and the class II fracture was restored with composite. Therefore, proper clinical and complete radiographic examination of both hard and soft tissues following dental trauma is essential to rule out such occurrences.
上颌前牙外伤性损伤在儿童中较为常见,这是由于玩耍时摔倒所致。牙硬组织外伤的后遗症包括折断、脱落、吸入和吞下的牙齿。另外一个危险是断裂的牙碎片嵌入软组织中,特别是在嘴唇。一位 10 岁男性患者主诉下唇疼痛。10 个月前曾有上前牙外伤史。临床检查显示下唇有瘢痕和变色,触诊时可感觉到硬肿块。口腔内检查显示 11 号牙的 Ellis 和 Davey Ⅱ类骨折。拍摄了唇部的 X 光片,显示出一个类似于缺失牙碎片形状的阻射结构。在局部麻醉下,成功地取出了牙碎片,并使用复合树脂修复了Ⅱ类骨折。因此,对于牙外伤,必须进行适当的临床和全面的软硬组织放射检查,以排除此类情况。
