Root resorption during orthodontic treatment: Clinical aspects and professional liability [Riassorbimento radicolare post-trattamento ortodontico: Tematiche cliniche e profili medico-legali]

Apical root resorption is an undesirable but frequent consequence of orthodontic treatment. Since biological processes underlying teeth movement are closely associated with its appearance, root resorption should be considered as unavoidable; it is possible, however, to limit the extension of this undesirable event. The aim of this article is to explain, by a literature review, the causal mechanisms associated with root resorption as well as to provide a legislative framework. When a root shortening greater than 2 mm determines teeth mobility and reduces function, professional liability and damage claims may have a sound basis. Another aim of this article is to propose guidelines for orthodontists in order to identify predictive clinical signs which allow to prevent litigation which can sometimes lead to criminal charges.
