This investigation studied the complication that could arise from delayed management of traumatized permanent teeth. Patients reported to the primary care clinic at the College of Dentistry, King Saud University, seeking treatment of traumatized anterior teeth were evaluated. Esthetic consideration (64 patients) and pain, swelling, or discomforts (50 patients) were the main reasons the patients came to the clinic. Clinical and radiographic examinations, as well as history of the trauma, were recorded. It was found that most of the patients had a treatment delay exceeding 1 month. Initial pulp exposure resulted in 100% pulp necrosis. When a fracture involved both enamel and dentin, the frequency of pulp necrosis was 53%. External root resorption and pulp calcification were seen in few teeth. It was concluded that the figures for pulp necrosis could be misleading, because there might have been a bias when only patients with problems sought treatment. In addition, a trauma awareness educational program should be developed to encourage parents and the public to seek immediate dental treatment. Furthermore, a proper diagnostic test for pulp and periodontal complication should be done in patients with initially nontreated dental injuries.
本研究调查了外伤恒牙延迟治疗可能引发的并发症。对前往沙特国王大学牙科学院初级保健诊所寻求治疗外伤前牙的患者进行了评估。美观因素（64例患者）以及疼痛、肿胀或不适（50例患者）是患者前来就诊的主要原因。记录了临床和影像学检查结果以及外伤史。结果发现，大多数患者的治疗延迟超过1个月。初始牙髓暴露导致100%的牙髓坏死。当骨折累及釉质和牙本质时，牙髓坏死的发生率为53%。少数牙齿出现了牙根外吸收和牙髓钙化。研究得出结论，牙髓坏死的数据可能具有误导性，因为可能只有有问题的患者才寻求治疗，存在偏差。此外，应开展创伤意识教育项目，鼓励家长和公众寻求即时牙科治疗。此外，对于最初未治疗的牙齿损伤患者，应进行适当的牙髓和牙周并发症诊断测试。
