Traumatic dental injuries affect 1 to 3% of the population, and disproportionately affect children and adolescents. The management of these injuries incorporates the age of patients, as children between 6 and 13 years of age have a mixed dentition. This helps to preserve the vitality of teeth that may be salvaged after a traumatic event. The clinical examination of these cases involves a thorough examination of the maxilla and mandible for associated fractures and any lodged debris and dislodged teeth or tooth fragments. The objective is to rule out any accidental aspiration or displacement into the nose, sinuses, or soft tissue. After ruling out any complications, the focus is on determining the type of injury to the tooth or teeth involved. These include clinical examination for any color change in the teeth, mobility testing, and testing for pulp vitality. Radiographic evaluation using periapical, occlusal, panoramic radiographs, and cone beam computed tomography is performed to view the effect of trauma on the tooth, root, periodontal ligament, and adjoining bone. The most commonly used classification system for dental trauma is Andreasen's classification and is applied to both deciduous and permanent teeth. Managing dental trauma is based on the type of injury, such as hard tissue and pulp injuries, injuries to periodontal tissue, injuries of the supporting bone, and injuries of the gingiva and oral mucosa. Hard-tissue injuries without the involvement of the pulp typically require restoration only. Any pulp involvement may require endodontic treatment. Fractures involving the alveolar bone or luxation of the tooth require stabilization which is typically achieved with flexible splints. The most common procedures employed in managing dental injuries include root canal/endodontics, surgical tooth repositioning, and flexible splinting. Recognition and treatment of these injuries are necessary to facilitate proper healing and salvage of a patient's natural dentition, reducing future complications to patients.
创伤性牙损伤影响1%至3%的人群,且对儿童和青少年的影响尤为严重。这些损伤的处理要考虑患者的年龄,因为6至13岁的儿童处于混合牙列期。这有助于保留在创伤事件后可能得以挽救的牙齿的活力。对这些病例的临床检查包括对上颌骨和下颌骨进行全面检查,以确定是否存在相关骨折、任何嵌入的碎片以及脱位的牙齿或牙碎片。目的是排除任何意外吸入或移位至鼻腔、鼻窦或软组织的情况。排除任何并发症后,重点是确定所涉及牙齿的损伤类型。这些包括对牙齿颜色变化的临床检查、松动度测试以及牙髓活力测试。使用根尖片、咬合片、全景片和锥形束计算机断层扫描进行影像学评估,以观察创伤对牙齿、牙根、牙周膜和邻接骨的影响。最常用的牙外伤分类系统是安德列森分类法,适用于乳牙和恒牙。牙外伤的处理基于损伤类型,如硬组织和牙髓损伤、牙周组织损伤、支持骨损伤以及牙龈和口腔黏膜损伤。未累及牙髓的硬组织损伤通常仅需修复。任何牙髓受累可能需要进行牙髓治疗。涉及牙槽骨骨折或牙齿脱位需要进行固定,通常使用弹性夹板来实现。处理牙损伤最常用的程序包括根管治疗/牙髓治疗、手术牙齿复位和弹性夹板固定。识别和治疗这些损伤对于促进患者天然牙列正确愈合和挽救、减少患者未来并发症是必要的。
