Abstract(s)
As reabsorções radiculares são consideradas uma das principais iatrogenias decorrentes da movimentação dentária induzida, apresentando magnitude variável e sendo, na maioria dos casos, imprevisíveis. No entanto, algumas reabsorções leves e controladas podem ser toleradas como custo biológico calculado, previsto no consentimento informado do paciente. Neste caso, para se atingir determinado objetivo estético e funcional, este fenómeno não deve ser considerado iatrogénico, mas sim um dano estrutural assumido.
Objetivo: Este estudo teve como objetivo encontrar e classificar os fatores que podem iniciar e induzir a reabsorção radicular apical externa durante o tratamento ortodôntico.
Metodologia: Foi realizada uma revisão narrativa na base de dados MEDLINE via PubMed, com os descritores “Orthodontic Treatment”, “Root Resorption” e “Risk Factors”, combinados com o operador booleano AND. Foram analisados 23 artigos publicados entre 2014 e 2024.
Resultados: Embora diversos fatores intrínsecos, clínicos e genéticos sejam citados, os principais fatores de risco para a reabsorção radicular apical externa incluem: tempo prolongado de tratamento ortodôntico, aplicação de forças pesadas e morfologia radicular anormal.
Conclusão: Devido à imprevisibilidade da reabsorção radicular e à sua dependência de múltiplos fatores, é essencial realizar diagnóstico cuidadoso, baseado em anamnese detalhada e exames radiográficos periapicais, para planear uma mecanoterapia que minimize os riscos de dano durante o tratamento.
Root resorptions are considered one of the main iatrogenic effects resulting from induced dental movement, often unpredictable and varying in magnitude. However, some mild and controlled resorptions may be tolerated as a calculated biological cost, foreseen in the patient’s informed consent. In this case, to achieve specific aesthetic and functional goals, this phenomenon should not be regarded as iatrogenic but as structural damage accepted knowingly. Objective: This study aimed to identify and classify factors that may initiate and induce external apical root resorption during orthodontic treatment. Methodology: A narrative review was conducted using the MEDLINE database via PubMed, with keywords “Orthodontic Treatment”, “Root Resorption”, and “Risk Factors”, combined using the Boolean operator AND. A total of 23 articles published between 2014 and 2024 were analyzed. Results: Although various intrinsic, clinical and genetic factors have been described, the most frequently associated risks include prolonged treatment duration, heavy orthodontic forces, and abnormal root morphology. Conclusion: Due to the unpredictability and multifactorial nature of external apical root resorption, careful diagnosis—based on anamnesis and periapical radiographic exams—is essential to plan treatment that minimizes potential damage.
