Abstract

The objective of the paper is to analyze the risk factors of root resorption, conditioned by orthodontic treatment, in order to eliminate them, as well as to prevent complications and achieve positive treatment outcome. The scholarly literature analysis was carried out using PubMed, Scopus, ScienceDirect, Google Scholar, and Research Gate database and it totally involved 60 papers published over the period of 2001-2019. The keywords were ‘root resorption; orthodontic treatment; tooth movement; orthodontic force’. The analysis revealed that development of the root resorption conditioned by orthodontic treatment is a common phenomenon which depends on a number of risk factors that are divided into host factors and treatment method factors. Host risk factors crucial for root resorption in the course of orthodontic treatment include teeth with existing root resorption during pretreatment, anterior open bite, abnormal root shape and teeth undergone root canal therapy. Significant risk factors for treatment methods include longer treatment duration, heavy force applied, intrusion and extrusion of premolars. The paper also presents the biomarkers of root resorption. Apical resorptions which are as a rule not infected are mostly stopped by discontinuing orthodontic forces. Cervical resorptions with a bacterial component require surgical intervention with curettage and restorative build-up of the resorbed area. Inflammatory root resorption conditioned by orthodontic treatment is inevitable, though, its progression into severe stage can be prevented in case early measures are taken and provided that the orthodontist is aware of the host factors, treatment risks and biomarkers involved.
正畸治疗对牙根吸收的影响
本文的目的是分析在正畸治疗条件下牙根吸收的危险因素,以消除这些危险因素,防止并发症的发生,达到积极的治疗效果。使用PubMed、Scopus、ScienceDirect、Google Scholar、Research Gate数据库进行学术文献分析,共涉及2001-2019年间发表的60篇论文。关键词:根吸收;矫正治疗;齿运动;矫正力”。分析表明,正畸治疗诱发牙根吸收的发展是一种普遍现象,它取决于多种危险因素,分为宿主因素和治疗方法因素。正畸治疗过程中对牙根吸收至关重要的宿主危险因素包括预处理过程中存在牙根吸收的牙齿、前牙开咬、牙根形状异常以及接受过根管治疗的牙齿。治疗方法的主要危险因素包括治疗时间较长、施加力大、前磨牙的侵入和挤压。本文还介绍了根系吸收的生物标志物。通常不感染的根尖吸收大多通过停止正畸力而停止。宫颈吸收与细菌成分需要手术干预刮除和恢复重建吸收区。正畸治疗引起的炎症性牙根吸收是不可避免的,但是,如果早期采取措施,并且正畸医生了解宿主因素、治疗风险和所涉及的生物标志物,则可以防止其发展到严重阶段。
