Types of root resorptions related to orthodontic treatment.

OBJECTIVES: Root resorption is one of the research topics that may be looked into and that may arise during orthodontic treatment. It is necessary to determine the type of root resorption that was caused by the orthodontic treatment, its factors leading to aforementioned issue, and means to eliminate it. MATERIAL AND METHODS: In this work, articles issued in 2008-2018 and found in biomedical systems such as PubMed and Oxford Journal have been used. The articles were selected with the keywords provided, 25 articles met all criteria. Other articles mentioned have been used for such root tooth resorption analysis, where at least one factor may have affected the issue under discussion. RESULTS: The mechanism of tooth movement during orthodontic treatment causes external or internal root resorption due to certain biochemical and biological processes. Factors, that cause root resorption during orthodontic treatment, were divided into local and general. Local factors include mechanisms of teeth movement, teeth vitality, length of treatment procedure - these factors may affect the type and level of resorption. General factors include age and other systemic elements. CONCLUSIONS: Root resorption extent and type depends on local and general factors active during the orthodontic treatment. It is not possible to eliminate all active factors, however the root resorption issue can be controlled during orthodontic treatment.
