“…A melhor maneira de tentar diminuir os riscos de uma complicação pós-cirúrgica em pacientes oncológicos é realizar a exodontia de dentes comprometidos periodonticamente ou com coroas afetadas de forma irreversível antes do início da terapia radioativa. Porém, o risco de exacerbação da ORN é aumentado bastante quando são feitas exodontias antes, durante ou após o tratamento radioterápico 6,7,21 .…”

“…O paciente acometido por câncer oral ou de cabeça e pescoço submetido ao tratamento radioterápico, além de patologias bucais, corre o risco de desenvolver osteorradionecrose dos ossos maxilares e mandíbula, sendo este risco aumentado por exodontias antes, durante ou após a radioterapia. Além disso, muitas vezes o tempo médio recomendado de cicatrização de exodontias (7-21 dias) é impossibilitado de ser respeitado no período pré-radioterápico, devido à urgência do início do tratamento oncológico, aumentando as chances do desenvolvimento da osteorradionecrose 6,7 .…”

Introduction: Cancer is currently among the five most common causes of death worldwide, resulting from harmful habits or genetic predisposition. Oral cancer plays a major role in this scenario and requires special dental care due to the association of tooth loss with cancer treatment. Aim: This study aimed at the biological analysis of the processes triggered by radiotherapy treatment and presentation of an alternative method for safe tooth extraction in cancer patients. Literature review: Cancer radiotherapy treatment triggers a series of oral complications that will eventually require tooth extraction, for example, osteoradionecrosis, hyposalivation, caries, and periodontal disease. Discussion: Tooth extraction with orthodontic elastics involves the tooth at the cervical height with elastics allowing a slow, gradual, and less traumatic exfoliation of the root; this process takes approximately 5 to 8 weeks. This technique is associated with a good postoperative recovery and ensures adequate healing, significantly increasing the likelihood of a positive prognosis. Conclusion: These techniques are safe and decrease the risk of postoperative complications, thus ensuring recovery without major problems for the patient.
