Reabsorção radicular apical externa durante o tratamento ortodôntico: fatores predisponentes

Abstract

This literature review aimed to present the relationship between external apical root resorption (ERR) of dental elements in relation to orthodontic mechanics, identifying predisposing factors, the consequences on compromised teeth and the conducts for identifying and managing ERR in orthodontic patients. Through the reviewed literature, it can be noted that episodes of external apical root resorption (ERR) are closely related to orthodontic mechanics and that there are numerous factors that potentiate the problem, among them: duration of therapy, previous root resorption, procedures that involving extractions, applied forces, type of bone and tooth morphology and orthodontic devices, malocclusion, previous dental trauma and genetic polymorphism. Even so, affected individuals may have a limiting impairment in the face of some dental situations that may occur and/or occur. Thus, in order to minimize the problem, it is of fundamental importance that the dentist request routine radiographic examinations, in order to assess the behavior of resorptions and thus take prudent measures in the face of the situation. Careful planning, dialogue with patients and family members and knowledge about the predisposing factors of external root resorption during orthodontic treatment by the professional will be of paramount importance in attenuating the resorptive process as a whole.
