This study aimed to identify possible associations of the presence or absence of posttrauma sequelae with the factors inherent to the traumatized tooth and treatment.
This retrospective study was performed through the evaluation of records and radiographs of a center of reference for dental trauma between January 2008 and December 2014. The factors were analyzed and associated with posttrauma sequelae, such as pulp necrosis and root resorption.
A binomial logistic regression model was fit ( < 0.05).
In luxations, it was possible to observe 37% pulp necrosis, 16% inflammatory root resorption, and 8% replacement resorption. The binomial logistic regression revealed that male gender ( = 0.0392, odds ratio [OR] = 2.79), avulsion injury ( = 0.0009, OR = 12.27), and elapsed time >16 days between the time of trauma to the beginning of the endodontic treatment ( = 0.0450, OR = 7.53) showed a greater chance of presenting a posttrauma complication.
Gender, type of injury, stage of root development, and time after trauma until the beginning of the endodontic intervention were related to the appearance of sequelae.
本研究旨在确定创伤后后遗症的有无与受创伤牙齿及治疗的固有因素之间可能存在的关联。
本回顾性研究通过评估2008年1月至2014年12月间一家牙外伤参考中心的记录和X光片进行。对这些因素进行分析，并与创伤后后遗症（如牙髓坏死和牙根吸收）相关联。
采用二项逻辑回归模型（<0.05）。
在牙脱位病例中，可观察到37%的牙髓坏死、16%的炎性牙根吸收和8%的替代性吸收。二项逻辑回归显示，男性（=0.0392，比值比[OR]=2.79）、牙脱位损伤（=0.0009，OR=12.27）以及从创伤发生到开始进行根管治疗的时间间隔>16天（=0.0450，OR=7.53）出现创伤后并发症的可能性更大。
性别、损伤类型、牙根发育阶段以及创伤后至开始进行根管干预的时间与后遗症的出现有关。
