The aim of this work was to study the incidence of complications of dental traumatisms and look for associations between factors related to trauma and the occurrence of complications. . It is a longitudinal retrospective study on a sample of 125 traumatized teeth. The sample is taken from patients consulting the dentistry service at the hospital Sahloul Sousse between 2014 and 2017. Criteria for including a patient were presence of a permanent incisor affected by a subluxation, intrusion, lateral luxation, extrusion, or avulsion injuries associated or not with concomitant dentoalveolar injuries. Data were collected using a questionnaire. The information about etiology of trauma, delay of consultation, orientation of the patient, kind of injury, and emergency treatment and complications were obtained from the patients' records.
The incidence of complications was 8%: external root resorption was present in 70% of cases, surface resorption was observed in 10% of cases, and replacement resorption in 10%, ankylosis in 10%. About pulpal complications, pulp necrosis was found after 4 weeks of follow-up, as well as the internal root resorption after one year. The most common cause of the trauma was the fall (40%). The majority of patients came for emergency consultation within "1 to 3 days," and the coronary fracture without pulp exposure was the first diagnosis (20.60%). Statistical analysis showed no significant relationship between the cause of the trauma and the complication (=0.577) and between the delay of consultation and complication (=0.577) and between the delay of consultation and complication (=0.577) and between the delay of consultation and complication (.
Treatment of dental injuries is usually delayed and not given as much attention as general medical treatment that can explain the occurrence of pulpal and periodontal complications. Immediate consultation and treatment could improve long-term prognosis of the injured tooth.
本研究旨在探讨牙外伤并发症的发生率，并寻找与创伤相关的因素与并发症发生之间的关联。这是一项对125颗外伤牙样本的纵向回顾性研究。样本取自2014年至2017年期间在苏塞萨赫勒医院牙科就诊的患者。纳入患者的标准为存在受半脱位、嵌入、侧向脱位、脱出或撕脱伤影响的恒牙，伴有或不伴有牙槽突损伤。通过问卷调查收集数据。从患者记录中获取有关创伤病因、就诊延迟、患者去向、损伤类型、急诊治疗及并发症的信息。
并发症发生率为8%：70%的病例出现外吸收，10%的病例观察到表面吸收，10%为替代性吸收，10%为粘连。关于牙髓并发症，随访4周后发现牙髓坏死，1年后发现内吸收。创伤最常见的原因是跌倒（40%）。大多数患者在“1至3天”内前来急诊，首次诊断为无牙髓暴露的冠折（20.60%）。统计分析表明，创伤原因与并发症之间（=0.577）、就诊延迟与并发症之间（=0.577）、就诊延迟与并发症之间（=0.577）以及就诊延迟与并发症之间（.均无显著关系。
牙外伤的治疗通常延迟，且未得到与一般医疗治疗同等的重视，这可能解释了牙髓和牙周并发症的发生。立即就诊和治疗可改善受伤牙齿的长期预后。
