External apical root resorption is an iatrogenic consequence of orthodontic treatment, although it may also occur in the absence of orthodontic treatment. Root resorption causes root shortening and breaks the integrity of teeth arch and this is very important for successful orthodontic treatment. Orthodontics is probably the only dental specialty that actually uses the inflammatory process as a means of solving functional and aesthetic problems. They should know the risk factors of root resorption and do everything to reduce the occurrence of root resorption. The aim of our review is to find, classify and estimate factors, that can initiate and induce root resorption during orthodontic treatment. The articles from 2002 to 2007 in English related to the topic were identified. Twenty four articles were selected for data collection. The severity and degree of root resorption associated with orthodontic treatment are multifactorial, involving host and environmental factors. The review shows that root resorption is significantly correlated with treatment duration, fixed appliance treatment, tooth structure, individual susceptibility, type of orthodontic tooth movement.
根尖外吸收是正畸治疗的医源性后果，尽管在未进行正畸治疗时也可能发生。牙根吸收会导致牙根缩短，并破坏牙弓的完整性，而这对于正畸治疗的成功至关重要。正畸学可能是唯一实际利用炎症过程来解决功能和美观问题的牙科专业领域。他们应该了解牙根吸收的风险因素，并尽一切努力减少牙根吸收的发生。我们综述的目的是找出、分类和评估在正畸治疗期间可能引发和诱导牙根吸收的因素。确定了2002年至2007年期间与该主题相关的英文文章。选择了24篇文章进行数据收集。与正畸治疗相关的牙根吸收的严重程度和程度是多因素的，涉及宿主和环境因素。综述表明，牙根吸收与治疗持续时间、固定矫治器治疗、牙齿结构、个体易感性、正畸牙齿移动类型显著相关。
